Through drastic rebuilding over four decades, Tehran has gone from a city of infinite gardens with single-family dwellings to a city of infinite apartment blocks. In a purely economically-driven construction process, the relationship between buildings and their urban fabric are lost.

As memories of place are wiped out, a metropolis with no stories left to tell takes shape. This is Tehran’s current cityscape. VOID+ is a residential scheme developed by Architect Maryam Pousti that challenges the city's environment.

The building is located in the northern part of Tehran, Iran. It strives to offer an alternative to conventional models of habitation and dense urban living, which has resulted in closed-up building envelopes that lack a dialogue with their context. Situated on an extremely narrow site, VOID+ consists of 10 units on five floors. The striking feature of the project is an intimate void strategically carved into the north facade in an attempt to engage the building with its periphery. The massing of the void creates a vertical flow between the skyline of the building and its feet.

The main entrance is defined by the particular moment when the verticality of the void turns into a horizontal plain stretched 20m along the length of the building. This horizontal platform connects the street level to the back garden. The aim is to redefine the building’s territory and to assimilate a single-family house that expands into its surroundings without the interference of rigid borders.

The interior layouts of the building reveal a deep structural and volumetric connection to the facade, a vocabulary that is used throughout the project. The juxtaposed volumes of the void offer playfulness through shifting perspectives and views, allowing the interior and exterior boundaries to be experienced simultaneously. The ‘hide and seek’ between inside and outside takes place through the interplay of solid and void, challenging notions of exposure and privacy.

There are two units on each floor, rendering noise and privacy as driving forces in the positioning of a rectangular stairwell, which acts as a buffer to prevent sound and direct visual contact between the units. Each unit sits around an intimate balcony, which is perceived as an interior garden.

There is an arrangement for materials and a hierarchy of finishes and textures, which celebrates the value of working with artisans. This is evident in the combed vertical cement pattern of the facade, which also acts as a conductor of rainwater, keeping the building’s skin clean. Door handles, railings, lighting fixtures and cabinets have been skilfully integrated into the architectural detailing of the building. Collaboration with makers of different backgrounds in this project is a reminder that buildings are a product of intense engagement and time.
