About Cu 29 Executive Office

Cu 29 is an executive office designed to support business meetings and temporary residential use. The project combines a formal workspace with the comfort of a private suite. Hidden doors integrate living functions while preserving the perception of an office environment. Dark surfaces emphasize copper elements inspired by the clients work with copper, while framed city views and materials define the spatial character of the project. Handcrafted mosaic details introduce an artistic element within the space. Strategically placed mirrors extend the Istanbul view deeper into the interior.

S.A.I.T. Studio's Cu 29 Executive Office represents a distinguished contribution to the contemporary discourse surrounding workspace design that honors material heritage while embracing forward-looking spatial philosophies, positioning itself within the broader movement toward biophilic and materially honest interiors that emerged prominently in the second decade of this century. The design demonstrates sophisticated understanding of how copper, referenced in the title through its atomic number designation, operates as both functional surface and symbolic carrier of meaning, with the oxidized ceiling treatment evoking alchemical transformation, geological time, and the patina of institutional permanence traditionally associated with spaces of authority and deliberation. The compositional achievement lies in the careful orchestration of multiple material voices, from the supple warmth of vegetable-tanned leather to the geological drama of figured marble, each element contributing to a polyphonic whole that rewards sustained visual attention while maintaining the functional clarity essential to productive workspace. The chromatic strategy demonstrates considerable accomplishment, establishing a predominantly warm analogous palette spanning copper, cognac, amber, and walnut while introducing strategic cooling moments through the blue-tinted panoramic vista and neutral stone accents that prevent visual fatigue. Thematic resonances extend beyond mere luxury signification toward deeper explorations of sanctuary, prospect, and the human need for spaces that simultaneously protect and inspire, the commanding view suggesting mastery while the enveloping warmth of materials offers comfort and groundedness. Iconographic references to the traditional gentleman's library, the alchemist's study, and the contemplative retreat interweave with contemporary sensibilities regarding transparency, light, and connection to the broader urban fabric. Viewers might consider how such spaces shape not only aesthetic experience but also the psychological conditions of creative thought and consequential decision-making.

Production Technology
The interior was realized through custom designed furniture, concealed door systems and integrated smart automation systems. Materials such as natural marble, laminated parquet flooring and solid copper transition profiles were carefully combined to emphasize spatial hierarchy. A smart automation system controls floor lighting, sun responsive motorized curtains and air purification devices, enabling flexible lighting, privacy and environmental comfort throughout the space.
Design Challenge
The main challenge was transforming a 120 sqm space into a hybrid environment functioning both as an executive office and a residential suite. Maintaining a strong office identity while integrating private living areas required careful spatial planning. Concealed doors, flexible layouts and material transitions were developed to preserve the formal office atmosphere while discreetly accommodating residential functions.
Project Duration
The project started in May 2025 in Istanbul, Turkey and was completed in August 2025. The interior was designed and realized within a residential tower located in the Fairmont Quasar complex.
Operation Flow
The space is organized to function primarily as an executive office. Upon entry, a glazed partition door frames the city view, creating a strong first impression. The layout enables smooth transitions between reception, meeting and lounge areas for business use. Concealed doors discreetly connect the kitchen and private rooms, allowing the space to transform into a comfortable residential suite when longer stays are required.
Research
Design research combined spatial analysis and user centered evaluation. The objective was to develop a hybrid executive office that could also support temporary residential use. Layout simulations, material studies and lighting tests were conducted during the design process. Observations of the clients workflow and meeting habits informed the spatial program. The result is a flexible environment balancing privacy, work efficiency and residential comfort.
Inspiration
The project was inspired by the clients involvement in the copper trade and the need for a refined environment where business meetings could take place outside the factory setting. The project combines the atmosphere of an executive office with the comfort of a private suite. Dark tones, copper details and framed city views shape a spatial identity that supports both professional use and temporary residential functions. The name Cu 29 refers to copper through its symbol and atomic number.

Design Interview about Cu 29 Executive Office

CU 29 was developed around a simple question: can a workspace offer the comfort, privacy and atmosphere of a home without losing its professional identity?

The project was designed as an Executive Office Residence rather than a conventional office. Today, many executives spend long hours in their workplaces, host guests, hold meetings, work individually and occasionally need spaces for rest and privacy. We wanted to bring all of these functions together within a single environment while maintaining a clear and coherent design language.

The inspiration came from contemporary lifestyles where the boundaries between work and personal life are becoming less defined. Instead of creating a strictly corporate setting, we focused on designing a place that feels personal, comfortable and lived in.

Material selection played an important role in expressing this idea. Natural stone, wood surfaces and custom copper details were combined with a dark colour palette to create a calm and masculine atmosphere. The result is a space that supports different ways of working while reflecting the character and lifestyle of its user.

Our main focus was to make every square metre work efficiently while maintaining a strong spatial character. The project area is only 120 square metres, yet it needed to accommodate a reception area, executive workspace, meeting and dining functions, a kitchen, guest facilities, storage areas and private living spaces.

Rather than separating these functions with conventional boundaries, we aimed to create a natural flow between them. Privacy was important, but so was continuity. Concealed doors, integrated storage solutions and carefully planned circulation helped us achieve this balance.

We also wanted to challenge the perception of scale. One of the key interventions was increasing the ceiling height from 2.60 metres to 3.20 metres. This significantly changed the spatial experience and allowed the interior to feel more open and comfortable.

From the beginning, our goal was not simply to design an office. We wanted to create an environment that people would genuinely enjoy spending time in, whether they were working, meeting guests or taking a moment away from a busy schedule.

CU 29 was designed for a specific client and location, but the ideas behind the project are highly adaptable. We see increasing demand for spaces that combine professional and residential qualities, particularly for business owners, executives and entrepreneurs whose daily routines no longer fit within the boundaries of a traditional office.

For future projects, we plan to continue exploring this type of hybrid environment while adapting it to different scales, cultures and lifestyles. Each client works differently, so the concept is not about repeating a design solution but about applying the same design thinking to new situations.

The project has also encouraged us to further investigate how privacy, comfort and functionality can coexist within compact spaces. Many contemporary workplaces prioritise efficiency, while residential interiors prioritise comfort. We believe there is still significant potential in bringing these qualities together in a more balanced way.

The design process took approximately four months, from the initial concept stage to the completion of the detailed design package.

A significant part of this period was spent studying how different functions could coexist within a relatively compact footprint. The project needed to accommodate professional and residential activities without feeling fragmented or overcrowded. This required several iterations of the layout before the final arrangement was established.

The ceiling intervention was another important part of the process. Increasing the ceiling height from 2.60 metres to 3.20 metres had a major impact on the overall spatial quality and influenced many subsequent design decisions, including lighting, material transitions and built-in elements.

Although the project was completed within four months, many of the ideas behind it came from our previous experience with residential and executive interior projects. In that sense, CU 29 was also the result of an ongoing design exploration rather than a concept developed in isolation.

This project was commissioned by a client who wanted a space that could support both professional and personal needs within a single environment. From the beginning, it was clear that a conventional office layout would not fully address the way the space would be used on a daily basis.

The client's lifestyle played an important role in shaping the concept. Meetings, focused work, hospitality, dining and private time all needed to be accommodated within the same setting. Rather than treating these requirements as separate functions, we approached them as parts of a continuous experience.

The project also gave us an opportunity to explore a subject that has interested us for some time: the changing relationship between working and living spaces. As professional routines become more flexible, the distinction between office and residence is becoming less rigid. CU 29 allowed us to investigate this condition through a real project with real constraints and expectations.

The design was therefore both a commissioned work and a chance to further develop ideas that we have been exploring in our practice for several years.

CU 29 was developed as a bespoke interior design project for a specific client and is currently in use as intended. The design was not created as a product or a concept to be licensed, sold or reproduced in an identical form.

Our practice focuses on creating site-specific solutions that respond to the unique requirements of each client, location and programme. For this reason, we do not approach projects as repeatable templates. Instead, we apply the underlying design principles to new situations and develop tailored solutions for each project.

That said, many of the ideas explored in CU 29, particularly the integration of professional and residential functions within a single environment, have informed our subsequent work. We expect these principles to continue evolving through future projects, adapted to different users and contexts rather than replicated directly.

This type of project emerged from a real observation rather than a predefined design ambition. Over the years, we noticed that many business owners and executives no longer use their offices solely as places for work. These spaces increasingly serve as environments for hosting guests, making important decisions, spending long hours throughout the day and occasionally finding moments of privacy away from a demanding schedule.

In this case, the client's expectations reflected that shift. The project required a setting that could support professional activities while offering the comfort and practicality of a private residence. This challenged us to think beyond conventional office planning and explore how different aspects of daily life could coexist within a single interior.

What interested us most was finding the right balance between openness and privacy. While the workspace needed to remain welcoming and representative, the residential functions needed to remain discreet. Concealed doors and carefully planned transitions allowed us to separate these areas without disrupting the overall spatial continuity.

Projects that bring together different modes of living and working often create the most interesting design questions. That is one of the reasons we were particularly drawn to this work.

Rather than being influenced by a specific designer or project, CU 29 was shaped by a broader interest in architecture and interior spaces that prioritise atmosphere, materiality and spatial experience.

We have always been drawn to projects where materials are allowed to express their natural character and where details are integrated into the architecture rather than applied as decoration. This approach influenced many decisions throughout the project, from the use of natural stone and wood to the incorporation of custom copper elements and concealed architectural features.

The project was also informed by our own experience designing high-end residential interiors. Many of the qualities people appreciate in a home, such as comfort, privacy, warmth and a sense of belonging, are often absent from traditional office environments. CU 29 was an opportunity to bring some of those qualities into a professional setting without compromising its purpose.

In that sense, the project was influenced less by individual references and more by an ongoing exploration of how people experience space, materials and daily life.

CU 29 was designed for an executive who required more than a conventional office environment. The target user is someone whose professional responsibilities occupy a significant part of daily life and who values comfort, privacy and flexibility alongside functionality.

The project is particularly relevant for business owners, entrepreneurs, senior executives and professionals who regularly host meetings, welcome guests and spend extended periods in their workplace. For users like these, the traditional distinction between office and residence often becomes impractical.

The design responds to this way of working by providing spaces for formal meetings and professional interactions while discreetly accommodating personal needs. Areas such as the bedroom, dressing room, bathroom and kitchen remain hidden from visitors through concealed transitions, allowing the user to maintain privacy without affecting the professional character of the space.

Ultimately, the project is intended for individuals who seek a workplace that reflects their lifestyle as much as their profession.

What distinguishes CU 29 is not the inclusion of residential functions within a workplace, but the way these functions are integrated without compromising either privacy or professionalism.

Many hybrid office concepts openly display residential elements as part of the design expression. In CU 29, we took a different approach. The kitchen, bedroom, dressing room and bathroom are positioned behind concealed doors and integrated architectural surfaces, allowing them to remain completely hidden when not in use. As a result, visitors experience the space as a refined executive office, while the user benefits from the comfort and practicality of a residence.

Another defining aspect of the project is the transformation of the existing volume. Increasing the ceiling height from 2.60 metres to 3.20 metres fundamentally changed the perception of space and allowed the interior to achieve a sense of openness that would not normally be expected within a 120-square-metre footprint.

The project is also characterised by a restrained material palette and a strong architectural language. Rather than relying on visual gestures or decorative elements, the design focuses on proportion, material quality, detailing and spatial continuity. This approach helped create an environment that feels both professional and personal without becoming overly corporate or overly residential.

The name CU 29 comes from copper, one of the defining materials of the project. "Cu" is the chemical symbol for copper and "29" is its atomic number on the periodic table.

Copper was not selected solely for its aesthetic qualities. The client works in the copper industry, making the material both professionally and personally meaningful. Rather than using copper as a decorative reference, we incorporated real copper into the project through custom architectural details and interior elements.

This connection between the client and the material became an important part of the design narrative. Copper contributes warmth and character to the interior while also reflecting the client's background and identity in a subtle way.

For this reason, the name CU 29 felt like a natural choice. It references a material that is physically present throughout the project and acknowledges the story behind why that material was chosen in the first place.

The project was developed using a combination of digital design, visualisation and technical documentation tools. Concept development, spatial planning and technical drawings were primarily carried out in AutoCAD, while three-dimensional modelling was developed in SketchUp.

For visualisation, we used Enscape to evaluate materials, lighting conditions and the overall atmosphere of the interior throughout the design process. These visual studies played an important role in testing different spatial decisions and communicating the design intent to the client.

Alongside digital tools, physical material samples were an essential part of the process. Since the project relies heavily on natural stone, wood finishes and real copper details, many design decisions were made through direct comparison of materials rather than solely on screen.

The design process moved continuously between drawings, models, visualisations and material studies, allowing both technical and aesthetic decisions to develop together.

The most unique aspect of CU 29 is the way it accommodates two very different modes of use within the same space without allowing one to dominate the other.

At first glance, the project reads as a refined executive office. Meeting areas, workspaces and reception functions are clearly defined and support a professional environment. What is less apparent is that the project also contains a fully functional residential programme, including a bedroom, dressing room, bathroom and kitchen.

These spaces are concealed behind integrated architectural surfaces and hidden doors, allowing them to disappear from view when guests or business partners are present. This approach preserves the privacy of the user while maintaining the formal character expected from an executive workspace.

Rather than treating the office and residential functions as separate zones, the design carefully manages the transition between them. The result is a space that can adapt to different situations throughout the day while maintaining a consistent architectural language and atmosphere.

Another distinctive aspect of the project is its relationship with the Istanbul skyline. The office benefits from panoramic city views, and we wanted those views to remain present throughout the interior rather than being experienced only near the windows. Mirrors integrated into the bar backdrop and selected wall surfaces reflect the skyline from different angles, extending the visual presence of the city deeper into the space and creating a constantly changing backdrop throughout the day.

CU 29 was designed by S.A.I.T. Studio through a collaborative process involving architects, interior architects, engineers and skilled craftspeople. While the overall design concept, spatial planning and material strategy were developed within our studio, the project benefited from the expertise of several specialised disciplines during both the design and implementation phases.

Structural consultants contributed to the feasibility of key architectural interventions, including the ceiling modifications that played an important role in the final spatial experience. Mechanical and electrical engineers were involved in integrating building systems without compromising the clarity of the interior design.

The project also required close coordination with manufacturers and craftspeople responsible for custom-made elements. Particular attention was given to the production of real copper details, concealed doors, bespoke joinery and material transitions, all of which demanded a high level of precision during execution.

We believe successful projects are rarely the result of a single discipline. CU 29 was shaped through the combined knowledge of different professionals working toward a shared design objective.

Technology plays a supporting role in CU 29. Rather than becoming a visible feature of the interior, it was integrated in a way that allows the user to benefit from it without disrupting the overall atmosphere of the space.

The project incorporates a smart home system that enables control of lighting, climate, curtains and selected building functions. This allows the user to adjust different settings according to changing needs throughout the day, whether hosting a meeting, working individually or using the residential areas.

Technology was also important during the design and coordination process. Three-dimensional modelling and visualisation tools helped us evaluate spatial relationships, material combinations and lighting conditions before implementation, allowing design decisions to be tested and refined throughout the project.

Our approach was to use technology where it improves comfort, efficiency and user experience while ensuring that the architectural qualities of the space remain the primary focus.

The project was not driven by formal academic research or quantitative data. Instead, it was shaped by a detailed analysis of the client's daily routines, working habits and spatial requirements.

At the beginning of the design process, we spent time understanding how the space would be used throughout the day. We studied the types of meetings hosted by the client, the level of privacy required in different situations, the frequency of guest visits and the relationship between professional and personal activities within the space.

This analysis directly informed many design decisions. The placement of the executive office, meeting areas and reception functions was carefully considered, while private spaces such as the bedroom, dressing room, bathroom and kitchen were positioned behind concealed doors to maintain privacy when visitors were present.

We also analysed the existing architectural conditions, including ceiling height, circulation patterns, natural light and the panoramic views of Istanbul. These observations influenced key interventions such as increasing the ceiling height and using reflective surfaces to extend the visual impact of the city skyline deeper into the interior.

Although the research process was primarily qualitative rather than statistical, it played a central role in shaping the final design.

One of the biggest challenges was accommodating a wide range of functions within a relatively compact 120 sqm space. The project needed to operate as an executive office while also incorporating a bedroom, dressing room, bathroom and kitchen without creating a sense of compromise between the two.

Maintaining privacy was another important challenge. We wanted the client to have access to all the comforts of a residential environment while ensuring that visitors, business partners and meeting guests experienced the space as a professional workplace. This led to the development of concealed doors and integrated architectural surfaces that hide the private areas from immediate view while maintaining a seamless interior composition.

The existing ceiling height was also a limitation. Increasing it from 2.60 metres to 3.20 metres required careful coordination with structural, mechanical and electrical systems. This intervention had a significant impact on the final spatial quality but introduced additional technical challenges throughout the design and implementation process.

Another challenge was balancing the strong material identity of the project. Real copper elements, natural stone, dark wood finishes and reflective surfaces all have distinctive visual characteristics. The design required careful control to ensure that these materials complemented one another and contributed to a cohesive atmosphere rather than competing for attention.

As with many interior projects, the most demanding aspect was bringing together technical requirements, user expectations and architectural intentions in a way that felt natural and effortless once completed.

We decided to submit CU 29 because it represented an approach that we felt could contribute to a broader discussion about contemporary working environments.

The project was developed for a specific client, but many of the questions it addresses are becoming increasingly relevant across different countries and cultures. How can workplaces support longer and more flexible daily routines? How can privacy be maintained without sacrificing openness? How can professional and personal functions coexist within the same environment? These were some of the ideas that motivated us to share the project with an international audience.

Design competitions also provide an opportunity to evaluate a project beyond its local context. Presenting the work to an international jury allows different perspectives and encourages reflection on the design decisions made throughout the process.

For our studio, participating in international competitions is not only about recognition. It is also a way to communicate ideas, exchange experiences and contribute to ongoing conversations about architecture and interior design.

CU 29 reinforced a principle that has guided our work for many years: every project should be shaped around the individual rather than around trends, predefined styles or widely accepted formulas.

The client did not provide a detailed design brief or specific visual references. Instead of asking what kind of interior he liked, we focused on understanding who he was, how he worked and how he wanted to feel within the space. The design developed from those observations rather than from a predetermined aesthetic direction.

The dark material palette was a good example of this approach. It was a bold decision and certainly not a solution that would suit every client. However, we were confident that it reflected the character of the person we were designing for, and we remained committed to that idea throughout the process.

After the first presentation, the client told us, "I did not know what I wanted, but this is exactly what I wanted. In such a short time, you understood me better than I understood myself." For us, that moment was not a lesson learned but a confirmation of something we already believed: meaningful design comes from understanding people first and designing spaces second.

Projects like CU 29 remind us why we continue to defend this approach in our practice.

One aspect that may help explain the project is the specific role it plays in the client's daily life.

The client already had an office within his production facilities. CU 29 was conceived as a separate executive office dedicated to hosting important clients, holding meetings and conducting business in a more private and refined setting. It was also intended to provide a comfortable environment for working, resting or spending time between appointments when necessary.

These requirements shaped many of the design decisions. Rather than creating a conventional office environment, we focused on establishing a balance between professionalism and comfort. The dark colour palette was chosen to reinforce a sense of formality and presence, while natural stone surfaces, real copper details and carefully selected materials contribute to the overall character of the space.

An important influence on the project's atmosphere was the idea of a contemporary private members club. Since many meetings would take place in this office, we wanted to create an environment that encourages conversation and hospitality rather than feeling strictly corporate. The leather Chesterfield seating, marble fireplace, custom bar, real copper details, dark wood finishes and natural textures were all selected with this intention in mind.

Several features were introduced to make the office feel more welcoming during long meetings and extended visits. The custom bar allows drinks and cigars to be served when hosting guests, while the fireplace adds warmth and familiarity to the interior. Together, these elements help create an environment that feels distinguished, comfortable and personal.

Ultimately, CU 29 was designed around a specific individual and a specific way of working. The project reflects our belief that every design should be shaped by the people who use it rather than by predetermined formulas, trends or expectations.
