About Terraced Horizon Villa

Terraced Horizon Villa is a contemporary hillside residence conceived as a continuation of its forested slope. Layered horizontal terraces step with the terrain, embedding lower floors while projecting upper volumes through deep cantilevers. Panoramic low e glazing and pronounced horizontal shadow lines draw daylight deep inside and extend views, reinforcing a continuous relationship between interior life and landscape. The steep topography is reconfigured into a calm sequence of inhabitable platforms and outdoor horizons, where shaded edges and terraces support comfort across seasons.

Interviews

Design Interview

What is the main principle, idea and inspiration behind your design?

The main principle behind Terraced Horizon is to transform a steep hillside into a livable architectural landscape. The inspiration comes from the natural stratification of landforms, terraces and plateaus shaped by time. Instead of placing a villa on the site as a separate object, the design follows the rhythm of the terrain. Strong horizontal lines, embedded lower levels and projecting upper volumes allow the residence to feel integrated with the forested slope while opening itself toward panoramic views.

What has been your main focus in designing this work? Especially what did you want to achieve?

My main focus was to create a residence that works with the topography rather than against it. I wanted to achieve a balance between grounded stability and visual openness. The villa needed to feel private, calm and protected, while still maintaining a strong connection with the surrounding landscape. Through terraced platforms, deep cantilevers, large glazed facades and shaded outdoor areas, the design aims to create a refined living experience where architecture and terrain become one continuous system.

What are your future plans for this award winning design?

My future plan is to use Terraced Horizon as a reference for further explorations of landscape-integrated residential architecture. The project opens important questions about how homes can adapt to challenging sites, how structure can support spatial openness, and how passive comfort can be improved through terraces, shading and natural ventilation. I would like to continue developing these ideas in future residential projects that require a sensitive relationship between building, landscape and daily life.

Grand Interview

The Terraced Horizon Villa has earned the Bronze A' Design Award in the Architecture, Building and Structure Design category, a recognition that celebrates creativity, structural ingenuity, and meaningful integration of form and function across some of the most compelling architectural works internationally. What aspect of the Terraced Horizon Villa do you feel best captures the spirit of this recognition, and which single design decision are you most proud of when you reflect on the project as a whole?

For me, the aspect that best captures the spirit of the Bronze A' Design Award is the way Terraced Horizon Villa transforms a difficult hillside into an architectural advantage. Rather than treating the slope as a limitation, the design uses it as the main generator of form, movement and experience. The villa becomes a continuation of the terrain, with lower levels embedded into the land and upper volumes opening toward the horizon through strong horizontal terraces.The design decision I am most proud of is this balance between grounding and projection. The building feels rooted in the forested slope, yet it also creates a sense of lightness through its cantilevered volumes. This duality gives the project its identity. It reflects our belief that architecture should not simply occupy a site, but interpret it, respond to it and reveal its hidden spatial potential.

Hillside residential architecture captivates design audiences worldwide, particularly when a building manages to feel simultaneously rooted in its landscape and liberated from it. How did the Terraced Horizon Villa navigate the tension between embedding lower levels into the forested slope and projecting the upper volumes outward through deep cantilevers, and what does this duality mean to you in terms of how the villa defines its relationship with the terrain beneath it?

Terraced Horizon Villa was designed around a deliberate dialogue between belonging and openness. The lower levels are embedded into the forested slope to give the building stability, privacy and a strong connection to the land. At the same time, the upper volumes extend outward through deep cantilevers, allowing the villa to open itself to the view, daylight and horizon.This duality was very important to the project. It allowed the villa to feel both protected and expansive. The embedded parts create a grounded, intimate relationship with the terrain, while the projecting volumes create a feeling of freedom and visual continuity with the landscape. For me, this is one of the strongest qualities of the design: it does not choose between being part of the land and rising above it. It does both, and that tension gives the house its architectural character.

The Terraced Horizon Villa employs a hybrid concrete and steel structural system to achieve large cantilever spans over a steep forested hillside, a technical approach that carries broader implications for how architects and engineers address severely sloped residential sites. How did the structural research undertaken for the Terraced Horizon Villa contribute to a deeper understanding of what is spatially and architecturally achievable on difficult topographies, and in what ways might this approach offer useful reference points for architects working in similar geographical and climatic conditions?

The structural research for Terraced Horizon Villa was essential because the architectural idea depended on achieving large horizontal projections on a steep hillside. The project required a careful balance between reinforced concrete elements that anchor the villa to the terrain and steel components that support the cantilevered volumes. This hybrid approach allowed us to explore how structure can become an active part of the architectural expression rather than a hidden technical necessity.Through this process, we gained a deeper understanding of how challenging topographies can create new spatial possibilities. Instead of producing a conventional stacked residence, the structural strategy made it possible to create terraces, voids, shaded edges and panoramic openings that respond directly to the slope. For architects working in similar conditions, I believe the project offers a useful reference for treating structure, terrain and spatial experience as one integrated design problem.

Unique Properties
Terraced Horizon is conceived as a series of horizontal platforms integrated into a sloping forested terrain. Lower levels are embedded into the ground, while upper volumes extend outward through deep cantilevers toward the landscape. Large glazed facades and pronounced horizontal roof lines create a layered architectural identity that strengthens the visual and spatial connection between interior living spaces and the surrounding nature.
Dimensions & Packaging
The villa has an estimated total construction area of approximately 1200 to 1500 square meters organized across three main spatial layers. Lower level garage technical rooms and service spaces embedded into the terrain. Main level open living areas kitchen dining and outdoor terraces
Terraced Horizon has an estimated gross built area of 1200 to 1500 square meters, arranged in three layers. The lower level includes the garage, technical rooms, and service spaces embedded into the slope. The main level contains open plan living, kitchen, dining, and outdoor terraces. The upper level houses bedrooms, private suites, and panoramic balconies. The structure combines reinforced concrete retaining walls with steel supported cantilever slabs. The envelope uses high performance low e glazing, natural stone cladding, and composite panels. Passive comfort is supported by deep overhangs, shaded terraces, and cross ventilation.

Production Technology
The villa uses a hybrid concrete and steel structural system. Reinforced concrete cores and retaining walls anchor the building to the sloped site, while steel beams and cantilevered slabs extend upper volumes over the landscape. Large format low e glazing with deep horizontal frames provides passive shading. Finishes combine natural stone, exposed architectural concrete, and wood textured composites. Recessed LED lines define walls, stair edges, and landscape at night.
Design Challenge
The primary challenge was to achieve a sense of architectural lightness while working with heavy structural systems required by the sloping site Large cantilevers had to be structurally efficient without dominating the visual expression. Another key challenge was preserving uninterrupted views while ensuring solar protection and privacy This was addressed through deep horizontal frames recessed glazing and a layered facade strategy. The final design creates a balance between landscape structure and living space transforming a steep hillside into an inhabitable architectural terrain.
Research
The project investigates how contemporary residential architecture can integrate with steep topography while maintaining spatial openness and visual continuity. Research focused on structural strategies for large cantilevers daylight penetration in terraced buildings and environmental benefits of layered shading. Material studies explored the balance between heavy grounded surfaces and transparent lightweight facades Climatic research prioritized passive cooling through shading natural ventilation and thermal mass.
Inspiration
The project is inspired by the natural stratification of landforms and the gradual shaping of hillsides over time. Drawing from the logic of terraces and natural plateaus, the architecture translates these principles into a contemporary residential language. Strong horizontal lines reflect the stability of the terrain and the rhythm of the surrounding forest, allowing the villa to read as a constructed landscape rather than an object placed upon it.
Project Duration
Designed and developed between 2024 and 2025, the project is located on a forested hillside site in Istanbul, Turkiye.
Operation Flow
Arrival occurs at the uppermost level through a landscaped approach. From this point, the house unfolds downward through a sequence of terraces and internal connections. Circulation is guided horizontally along panoramic facades, enabling continuous engagement with the landscape. Large sliding openings allow interior spaces to expand seamlessly into outdoor terraces. Vehicle access and garage functions are discreetly located at the lower level, separating service circulation from the main residential experience.
