About this service
About custom home design & build
A custom home design and build service provides a complete solution for creating a bespoke residence. Unlike standard new builds, custom homes are designed around your specific lifestyle needs, site conditions, and aesthetic preferences. We integrate architecture, structural engineering, and construction into a seamless process. Custom homes typically start from £225,000 and take 9 to 15 months from design to completion.
Who it's for
Discerning clients who want a home designed specifically for their needs rather than adapting to an existing property. Custom homes are ideal for unique sites, complex briefs, or clients with specific sustainability or accessibility requirements.

FAQ
Common Questions
Design and build is a project delivery method where one company handles both design and construction under a single contract. It gives you a single point of responsibility and can improve coordination, speed, and cost control compared with a more fragmented route.
Bespoke custom homes in London typically cost more than a straightforward new build because the design, coordination, and finish are more tailored. As a guide, compact bespoke homes often start from around £225,000, with the cost per m² rising as complexity and specification increase.
Yes. We have experience delivering Passivhaus and other high performance sustainable homes. Passivhaus design requires careful attention to insulation, airtightness, and mechanical ventilation with heat recovery.
From initial brief to completion, custom homes typically take 12 to 18 months. This includes 3 to 6 months for design and planning, and 9 to 12 months for construction. Complex or larger homes may take longer.
