(01) — The Studio

A quiet practice built on proportion, patience and honest material.

Antra is a twelve-person studio working across architecture, interiors and objects. We begin every project with the site — its light, its history, the way people already move through it — and let the plan grow from there. Nothing decorative that isn't also structural.

“A room is finished when there is nothing left to remove —
only light, surface and the people inside it.”
Elin Haugen — Founding Partner
Our Process

Four steps, no surprises along the way.

Every stage is signed off — drawings, costs and programme — before the next one starts. You always know what happens next and what it costs.

01
Week 01 — 02

Listening

A long first conversation, a site visit, and an honest brief with real numbers attached.

  • Measured site survey
  • Written brief
  • Realistic budget range
02
Week 03 — 06

Concept

Plans, models and a material board. One direction, argued for — not five to choose from.

  • Floor plans & layouts
  • Material palette
  • 3D views of key rooms
03
Week 07 — 12

Detail

Technical drawings, joinery, lighting and procurement. Everything specified before site starts.

  • Construction drawings
  • Joinery & lighting design
  • Full FF&E schedule
04
Week 13 — handover

Delivery

We run the site, snag it, style it and hand you the keys with a maintenance file.

  • Weekly site supervision
  • Snagging & sign-off
  • Styling and handover file

Typical programme for a whole-house scheme. Single rooms run to about a third of it.
