Chapter 04From brief to handover

Five phases. Predictable.

Most projects move from first walk to permit set in eight weeks.

    Site visit + brief
    We walk the site, take measurements, and pin the brief in one session — not three.
  2. 02
    Schematic options
    Two or three real schemes in plan and 3D. Pick a direction; we kill the rest.
  3. 03
    Design development
    Materials, fixtures, joinery details. You sign off on the palette before drawings start.
  4. 04
    Permit + CDs
    Construction set, specs, permit submittal. We handle the city back-and-forth.
  5. 05

Chapter 06Blueprint · about the studio

The blueprint, in four marks.

Hospitality, residential and retail interiors — drawn, detailed, quietly built.

06
i.
No canvas is impossible

The medium is a starting point, never a limit.

ii.
Character before style

Every client carries a unique voice — we render that character into form.

iii.
Made to outlast

Materials, drawing and detail chosen for the long, quiet life of the object.

iv.
Spread creative wisdom

Every project leaves the discipline better than we found it.
