ZAV Architects Extends Iranian Villa with Ombre Architectural Limbs
A colorful, vaulted extension transforms a weekend villa into a permanent residence in Kouhsar.
1Residential Transformation in Kouhsar
ZAV Architects has completed a significant extension to a weekend villa located on the outskirts of Tehran. Originally designed by Firouz Firouz, the residence has been converted into a permanent home. The project, named Golmorad, expands the structure into three adjacent orchard plots acquired by the client to accommodate new living requirements.
2Organic Architectural Grafting
The studio describes the design process as a form of architectural grafting rather than a simple addition. By extending the home into new wings, the architects created distinct organs that branch out from the original core. This approach allows the building to evolve while maintaining the logic of its original thick-earth construction methods.
3Vaulted Geometry and Layout
The extension consists of a series of overlapping arched roofs constructed from masonry and coated in plaster. At one end, the structure splits into two curved forms of decreasing height. One wing houses a private bedroom and ensuite, while the other features an open-plan kitchen, living, and dining area facing an outdoor pool.
4Chromatic Gradient Design
A striking feature of the project is the color gradient that transitions from terracotta to blue. This ombre effect radiates outward from the existing core toward the newly formed branches. The studio intended this spectrum to make the process of the building's transformation visible, with each segmented shell representing a distinct stage.
5Natural Light Integration
To enhance the interior atmosphere, the architects incorporated specific openings between the overlapping roof planes. These gaps allow natural light to penetrate deep into the home's interior spaces. The design ensures that the new volumes feel connected to the original structure while providing modern amenities and improved spatial flow for the residents.
6Material and Structural Logic
While the extension utilizes curved geometries that clearly distinguish it from the original villa, it remains grounded in traditional techniques. The use of masonry and plaster ensures the new sections blend with the earthen exterior of the predecessor. This balance creates a cohesive aesthetic that honors the villa's history while embracing contemporary architectural forms.
7Recognition and Awards
The Golmorad project has gained notable attention, being shortlisted in the house extension category of the Dezeen Awards. It recently secured the public vote alongside another project by ZAV Architects. This recognition highlights the firm's growing influence in contemporary Iranian architecture and their ability to blend functional needs with artistic expression.
8Architectural Context and Legacy
ZAV Architects continues to build on their reputation for colorful, context-sensitive design. Last year, the firm was recognized with an Aga Khan Award for Architecture for their work on the Majara Residence in Hormuz. Golmorad further demonstrates their commitment to exploring how architecture can emerge organically from existing structures and landscapes.
