(03) How we work

  1. 01

    Start with the ground

    Every project begins with a survey: levels, light, soil, neighbours, history. The building is measured against what's already there.

  2. 02

    Keep what's worth keeping

    The greenest building is usually the one already standing. We repair, reuse and add, and only demolish when there's no better answer.

  3. 03

    Draw it until it's simple

    Good buildings look obvious once they're built. Getting there takes a lot of drawings, most of them thrown away.
