Contemporary new-build house on a London infill plot

New build design

Every successful new build starts with an honest feasibility.

London's backland, infill and corner plots can be highly valuable — or unviable. Access, overlooking, daylight, trees and drainage decide which. We test these constraints before you commit, so the scheme that goes to planning is one the council can approve and a builder can price.

Feasibility study

Capacity, constraints, planning risk and likely value — a clear written answer on what the site can deliver.

Planning

Design development, pre-application advice and the full planning submission with supporting statements.

Technical design

Building regulations drawings, structural design and tender information ready for contractors.

Is my site suitable for development?

Side gardens, garage plots, backland and underused commercial sites across London regularly secure consent for new homes. The deciding factors are access, separation distances to neighbours, daylight and sunlight, trees, flood risk and local policy on character. A feasibility study answers these in writing before significant fees are spent.

How do new build planning applications work?

New dwellings need full planning permission, and most London boroughs expect pre-application engagement, a design and access statement, and supporting surveys. We prepare the complete submission, manage the case officer process, and respond to comments through to decision.

What does a new house cost to build in London?

Build costs for a new house in London typically range from £2,500 to £4,000 per square metre depending on specification, access and ground conditions. We design to a target budget and can introduce builders at the right stage for market testing.

Joined-up design and structure

Foundations, retaining walls and frames are engineered by the same team that designs the house, so structure is resolved in the layout rather than patched in later — fewer surprises on site and a cleaner route through building control.
