Our expertise in high-end residential architecture

Good residential architecture in London starts with what the building and the borough will allow. Our design team reads the constraints first, then designs a home we can price and build ourselves.

  • Feasibility and options

    What the house or site can become, tested against planning policy and space standards.

  • Planning in sensitive settings

    Conservation areas and listed neighbours read before design. See planning permission.

  • Layouts and extensions

    Floor plans, roof and basement space, extensions and reconfigurations.

  • Technical design

    Structure, services, fire strategy and Building Regulations coordinated before we price.

  • Interiors and joinery

    Finishes, lighting and joinery drawn by the same team. See high-end interior design.

  • Build

    Our construction team builds the design under the same contract. See house renovation.

How a residential design project runs

We meet, see the property and agree the brief. Design projects start from £15,000; the scope is set at this stage.

Planning context, structural condition and constraints mapped side by side.

At Allitsen Road in St John's Wood we developed four options, from minimal intervention to full conversion, each tested against planning policy and London Plan space standards.

We prepare the planning application, then the technical design the build is priced from.

Our team builds it to a lump-sum price and closes every snag before handover.

High-end residential architects: your questions

How much does a high-end residential architect cost in London?

Our design projects start from £15,000; the scope of the fee is agreed at the consultation. See also luxury home design costs.

Do you handle planning permission?

Yes, with our planning team. See planning permission. At Allitsen Road, a conservation-area building opposite two Grade II listed properties, every design option was tested against planning policy first.

Can you design and build?

Yes. Our design team and construction team work under one contract, so the price and the build follow the design you approved.

Do you work on existing homes as well as new ones?

Yes. Our residential projects so far have been existing London homes, from penthouses to a private residence in Knightsbridge.

What should I think about before I start?

What you want the house to do for you, what the planning context allows and your total budget including the build. Our articles on luxury home planning mistakes and features of luxury home architecture are a good start.

How long does a design project take?

It depends on the brief and on planning. We set the programme with you at the consultation.
