Great design deserves great delivery
A main contractor for considered, architect-led homes.
The team behind Henley have worked with private clients, developers and architects for over twenty-five years, from design stage or once drawings are in place. Typical contracts range from £150,000 to £1.5m across London and the Home Counties.
What we build
From a single-storey extension to a whole home.
We engage with clients either from the design stage — alongside a panel of trusted, talented design partners — or once designs are in place, to deliver the construction phase with transparency and care.
- Extensions — single & double-storey, rear, side and full-width
- Refurbishment & remodelling — whole-house transformation and interiors
- New-build homes — ground-up residential construction
- Listed & conservation — sensitive work to period and protected buildings
- Basements — new lower-ground space and structural remodelling
- Fit-out & joinery — Crittall, herringbone, marble, bespoke staircases

How we work
A ten-step design & build process.
From a no-obligation first meeting to aftercare months after handover, every scheme is led by an experienced project manager — your single point of contact — supported by systems you would expect on far larger contracts.
- One point of contact — a dedicated project manager throughout
- Fixed-price transparency — detailed tenders and fortnightly valuations
- Value engineering — protecting quality while managing cost to budget
- Weekly reporting — Gantt programmes, photos and clear communication
Their depth of experience and commitment to quality are evident in every aspect of their work. The team communicates seamlessly with both the architect and the client, ensuring design intent and construction execution remain perfectly aligned.Keeps ArchitectsDesign partner · five projects together
