About Gnt Interior Design Office

Gnt Interior Design Office reconfigures a 25 square meter interior with a 5.5 meter ceiling into a compact workspace organized around clarity and spatial efficiency. A steel mezzanine without side wall connections enables vertical expansion while maintaining visual continuity. Transparent and reflective surfaces enhance spatial perception, while a sculptural staircase and vertical lighting emphasize height and spatial depth. Material contrast and integrated design systems allow multiple functions to coexist within a visually calm and continuous environment.

Interviews

Grand Interview

The steel mezzanine at the heart of Gnt Interior Design Office is a remarkable feat of structural ingenuity, engineered without any side wall connections and supported solely by the floor within a 25 square meter footprint. Could you walk us through the moment you conceived this solution and what it meant to you, both as the architect and as the client of your own space, to see that structural idea become a physical reality?

The steel mezzanine emerged from a spatial challenge rather than a structural ambition. Although the office occupies only 25 square meters, it has a ceiling height of 5.5 meters. This unusual proportion made the space feel narrower and deeper than it actually was, creating a tunnel-like perception.My goal was to break down this vertical scale and create a more balanced spatial experience while gaining additional functional area. The mezzanine allowed us to introduce storage and a small service space above, while preserving the openness of the main working area below. The floating wooden staircase became a sculptural element that connected these two levels and helped transform the height into an architectural feature rather than a challenge.As both the designer and the user of the space, witnessing this idea become reality was particularly meaningful. The project reinforced my belief that limitations often lead to stronger design solutions. What began as an effort to solve a difficult spatial condition ultimately became the defining element of the entire office.

Compact urban workspaces are among the most pressing design challenges facing interior architects today, and Gnt Interior Design Office stands as a compelling case study in how vertical dimension can compensate for limited floor area. How do you believe the spatial strategies developed within Gnt Interior Design Office could inform a broader conversation about the future of small-footprint professional environments in dense cities like Istanbul?

Evaluating small spaces only by their floor area means overlooking much of their potential. With the GNT Interior Architecture Office, I wanted to show that a space is not defined by square meters alone. When carefully planned, both visible and hidden solutions can allow all functional needs to be accommodated within the same volume. For this reason, I considered both horizontal and vertical space as active parts of the design.The mezzanine, concealed storage areas, multifunctional surfaces, and materials that enhance visual continuity allowed us to make a relatively small space work much harder. The main idea was to organize the available volume in a way that could support all of our needs without compromising the spatial experience.I believe future workspaces will become increasingly compact, while shared-use environments will become more common. As a result, spaces that make better use of every square meter and can adapt to different needs will become even more valuable. The GNT Interior Architecture Office was designed around this idea.

The integration of concealed elements, including a sink, television, and storage, within the fixed surfaces of Gnt Interior Design Office is a quietly radical approach that keeps visual calm intact while expanding functional capacity. What specific design and engineering methodologies did you develop during the realization of Gnt Interior Design Office that you had not previously employed, and how did precision manufacturing and on-site adjustments shape the final outcome?

One of my main goals in the GNT Interior Architecture Office was to create a calm and cohesive spatial experience by making as many functional elements as possible invisible. For this reason, I developed several custom detail solutions throughout the project.One of the most important was the sink concealed within a large storage unit. To keep the sink completely hidden, I used a glass countertop solution that I had not implemented before. The operable glass cover and the faucet that appears only when needed allowed me to eliminate the visual presence of a kitchenette in everyday use.Similarly, I did not want the television to remain permanently visible. Instead, it was concealed within a volume designed as the supporting leg of the main work desk. When needed, it rises through a lifting mechanism and can be used for presentations and meetings. This detail not only creates an unexpected experience for visitors but also helps preserve the clean character of the workspace.Precision fabrication and on-site adjustments played a major role in the success of these solutions. The concealed sink system, the technical infrastructure integrated within the desk, the custom glass cut-outs, and the precise alignment between the staircase and storage elements all required millimetric accuracy and careful coordination. In the end, these technical details remain largely unnoticed by users, yet they are essential to maintaining the simple and calm atmosphere of the space.

Unique Properties
Gnt Interior Design Office reconfigures a 25 square meter interior with a 5.5 meter ceiling into a compact, highly integrated workspace. A steel mezzanine without side wall connections enables vertical expansion while preserving spatial continuity. The design functions as a multi-functional system, integrating concealed elements within a limited footprint. Transparent elements, mirrored surfaces, a sculptural staircase, and vertical lighting emphasize height, openness, and spatial perception.
Dimensions & Packaging
Area: 25 square meters. Ceiling height: 5.5 meters. The vertical dimension enabled the introduction of a steel mezzanine, allowing spatial expansion within a limited footprint. The compact floor area required precise planning, where all functional elements were integrated and concealed to optimize usability and maintain spatial clarity.

Production Technology
The project combines laminated solid wood parquet, solid wood elements, block marble, mirror surfaces, painted glass, and lacquered cabinetry. A steel mezzanine system was engineered without side wall connections. Custom detailing enabled the integration of hidden elements such as sink, television, and storage within fixed structures. Precision manufacturing and on-site adjustments were essential to accommodate material weight, spatial constraints, and structural requirements.
Design Challenge
The main challenge was stabilizing a steel mezzanine supported only by the floor without wall connections due to structural constraints. Transporting and installing heavy block marble within a limited space required sectional cutting. Municipal regulations restricted mezzanine depth, affecting circulation planning. Coordination with engineers and detailed redesign ensured structural safety and precise integration of all elements.
Research
This project is based on qualitative design research focusing on spatial efficiency within a compact, high-ceiling office. The objective was to integrate multiple functions without visual clutter. Methods included on-site measurements, mezzanine planning under municipal regulations, and layout studies using sketches and 3D models. The designer acted as both client and tester. Results showed that concealed systems improve usability and clarity.
Inspiration
Based on a “less is more” approach, the design is inspired by the challenge of integrating multiple functional requirements within a compact office space. It explores how complexity can be concealed within a clear spatial expression, using vertical expansion and a transparent mezzanine to enhance perception. Material contrast between block marble and solid wood informs the balance between density, warmth, and atmosphere.
Project Duration
The project started in November 2017 in Istanbul, Turkey and was completed in May 2018.
Operation Flow
The space operates through integrated and concealed elements that allow multiple functions to coexist without visual clutter. Storage, media units, and kitchen components are embedded within surfaces, enabling a clear workspace. Natural light is amplified by full-height glazing and reflective surfaces, while the mezzanine introduces vertical circulation. The result is an environment that remains open, adaptable, and easy to use, where functions are accessible yet visually hidden.
