Service introduction

Good interiors start before the first paint swatch

Walls move, loads travel and codes decide what is possible. Our architects survey your building to the millimetre, test what can change, and draw a legal, buildable shell — so the interior design that follows rests on certainty, not assumptions.

From brownstone extensions to loft combinations and landmark-adjacent alterations, we handle drawings, filings and structural coordination in-house.

How it runs

From survey to stamped set

  1. Step 1

    Survey & brief

    Laser measurement, photos and a working session on what must change — and what must not.

  2. Step 2

    Concept layouts

    Two to three test-fits compared side by side for flow, light and cost impact.

  3. Step 3

    Approvals

    We prepare, file and chase planning and board approvals until the stamp lands.

  4. Step 4

    Build-ready set

    Dimensioned construction drawings contractors can price and build from directly.
