This project involved expanding an old villa near Tehran, used for weekend family gatherings. Originally, it was a 12x12 meter house with three bedrooms, which was insufficient to accommodate a large family in need of additional rooms. The design process began by studying the relationship between the rooms and the common spaces of the house. As we explored different design alternatives, we decided to give each room a distinct, independent identity, reflecting the primary reason for the expansion. This idea of independence became a key feature, shaping the building’s exterior form and making the rooms visible and legible in the overall structure.
As the concept developed, this approach of giving distinct forms was applied not only to the bedrooms but also to other secondary spaces within the building. For example, a semi-open space was introduced at the center of the villa for gatherings throughout the seasons, as well as a staircase leading to the roof and an exercise area.
The expansion extended the house eastward, increasing its length from 12 meters to 70 meters, with a height of 6.5 meters. Our design strategy transformed the project into a simple gray platform made of granite, with independent, distinct white sloped boxes placed on it. These are clearly identifiable and recognizable in the building's exterior form. The spatial units were carefully arranged on the granite platform (which serves as the common area) in line with our design intentions.
The swimming pool and the building's public spaces were all situated on the main platform, while the rooms, located on the first floor, were grouped into two sets of three rooms, along with a separate main bedroom. Both the rooms and other secondary spaces were designed as white spatial boxes with sloped roofs. The negative spaces between these volumes, sitting on the gray granite platform, create internal voids and contribute to a sense of openness within the building. Two long corridors—one on the ground floor and another on the first—run through the spatial boxes, serving as linear connectors between different parts of the house.
