ZAV Architects has designed the extension of Golmorad in Tehran, Iran.

The Golmorad extension transforms a weekend villa into a permanent home in Kouhsar town on the outskirts of Tehran and Karaj – where temporary stays are intended to become permanent.

"The concept addresses an anatomical growth, where new members are added to an existing body to provide space needed for permanent habitation," said ZAV Architects.

This is achieved through a sequence of interconnected vaults that crawl into the garden, integrating the villa into a larger whole.

Using a carved design language with low-tech masonry and local craftsmanship, Golmorad proposes an alternative model for suburban development based on extension, rather than replacement.
