Studio

Forty-two people. One drawing table.

Architects, landscape architects and engineers in Istanbul. One studio, one drawing table, and every building drawn by the same hands from first survey to handover.

Philosophy

We stay small on purpose. At forty-two people, we are large enough to build a library and small enough to know every junction in it by name. The partner who draws the first line is still on site when the last stone is set.

Principles

Three ideas we have kept since 2004. Every drawing is tested against them.

  • Site before style.

    We don’t arrive with a signature. We arrive with a survey, and the building grows out of the ground it stands on.

  • Build once. Build well.

    The most sustainable building is the one nobody needs to replace. We choose materials that age into their beauty.

  • Leave room for light.

    Light costs nothing and changes everything. We design the rooms around it first, and the walls second.

Leadership

Who you’ll work with.

The partners and directors of the studio. One of them leads your project from the first site walk to the day we hand over the keys.

  • Astrid Halden

    Founding Partner · Istanbul

    Trained at the Royal Danish Academy. Leads every project from first sketch to handover, and still draws the first plan by hand.

  • Karim Voss

    Founding Partner · Istanbul

    Co-founded the studio in 2004. Twenty years designing buildings for extreme climates, from the Arctic to the Empty Quarter.

  • Lina Haddad

    Led Qasr Al Nour and Atlas Desert Lodge. Writes and teaches on shade as the first material of Gulf architecture.

  • Mikkel Brandt

    Director of Technical Design · Istanbul

    Responsible for every junction, specification and site review. Believes a building is only as good as its worst detail.

  • Noor Al-Sayed

    Head of Landscape · Istanbul

    Landscape architect behind The Quarry Garden and Wadi Terraces. Plants for the century, not the opening.

  • Jonas Ek

    Head of Sustainability · Istanbul
