We specialise in turning a vision into something that can actually be built. Eighteen people, one room, and every drawing done here.
Architectural design
New build, extension and conversion, from the first sketch through planning to the drawings a contractor can price.
Interior design
Layout, light, materials and the joinery that makes a plan work once people are actually living in it.
Workplace
Offices, studios and showrooms. Space planning, acoustics and a fit-out package that survives contact with a building manager.
Retrofit
Fabric-first upgrades to existing buildings: insulation, glazing, airtightness and the heating that then actually suits the house.

Five year aftercare
Antra is eighteen people in one room in London. We draw everything ourselves,
we visit every site, and the person you meet first stays on the job to the end.
Yes. A single room done properly is a good project. What we will not do is take a job on and then hand it to someone junior because it is small.
Do we need planning permission?
Often not. Permitted development covers more than people expect. We tell you at the first visit, and if an application is needed we handle it.
How are you paid?
Fixed fee per stage, agreed before the stage starts. No percentage of construction cost, because that rewards us for making your building more expensive.
Can you work with our builder?
Yes, and we would rather you had one you trust. If you do not, we can tender the job to three and help you read the returns.
