01 — The Studio

A practice built on restraint and daylight.

We begin every project by asking what a place already knows — its light, its weather, its habits of use. What we add is measured against that.

Founded in 2009, Arc Studio works across scales from a single room to a city block. We keep the practice deliberately small: three partners, eighteen people, and no more than ten live projects in the studio at any one time. Every drawing that leaves this office has been drawn, questioned and redrawn by one of us.

Our buildings are quiet, durable and generous. We specify honest materials — concrete, timber, stone, lime — and detail them so they age into something better than they began.

03 — Services

Three ways we work with you.

Design, consultation or interior — the same studio, the same standard of drawing. Most clients begin with a feasibility study and stay with us to the final snag list.

Full-service architectural design from first concept to completion on site. We lead the whole process — planning strategy, technical documentation, tender and construction administration — so nothing is lost in the handover between teams.

  • 01Concept & feasibility design
  • 02Planning applications & consents
  • 03Technical drawings & specification
  • 04Tender, site delivery & handover

Typical engagement runs 12 – 36 months. We work in RIBA-aligned stages and are happy to join an existing design team at any point in the programme.

New buildExtensionsAdaptive reuseCompetitionsMasterplanningHeritage

Before you commit land, capital or a decade, you need an honest read on what a site can carry. We test capacity, daylight, planning risk and cost per square metre — then tell you what we would do if it were ours.

  • 01Site appraisal & capacity studies
  • 02Planning risk & pre-application advice
  • 03Sustainability & energy roadmaps
  • 04Design review & second opinions

Delivered as a fixed-fee study, usually inside four to eight weeks, with a written report, massing options and an indicative cost envelope you can take to a board.

FeasibilityDue diligenceCost planningNet zeroRetrofit strategy

The inside is not decoration applied at the end — it is where the building is actually lived. We design interiors as spatial problems first: light, sequence, storage, acoustics, the path you take from the door to the desk.

  • 01Spatial planning & layouts
  • 02Bespoke joinery & detailing
  • 03Materials, finishes & FF&E
  • 04Lighting design & site styling

We keep a working material library in the studio and prototype joinery at full scale before it is made. Commissions range from a single apartment to a forty-room hotel.

04 — People

Eighteen people. Three partners.

We are deliberately small. The people who draw your building are the people who visit the site, chair the meetings and sign the drawings.

Awards & citations.

Recognition is a by-product of the work, not the reason for it. Listed here because clients ask — and because the people who built these projects deserve the record.
