Not just builders — the design, conservation and structural experts behind prime London homes
OLBC — the Oxford & London Building Consultancy — is a multidisciplinary practice: architecture, interior design, conservation, structural engineering and construction, all in-house. For over twenty years, prime-London homeowners and their architects have brought us in for the work that needs more than a contractor:
- Listed-building restoration
- Structurally complex renovation
- Whole-house projects, from Kensington and Chelsea to Wandsworth and Wimbledon

Why a consultancy, not a contractor
Most prime renovations mean assembling a team — architect, structural engineer, interior designer, main contractor — and hoping the seams hold.
OLBC removes the seams. Design, planning, conservation, structural engineering and construction are all in-house, run by one team under a single point of accountability.
It’s why our planning consent record is 100%, why our own structural crews — never subcontracted — handle the most sensitive underpinning and basement work, and why a project that would otherwise pass through four firms passes through one.
- 20+ years
- 100% planning consent record
- In-house design, structural & construction teams
- £10m employers’ liability
- £1m professional indemnity
- JCT contracts
- A Director on every project
What we take on
Listed buildings & conservation. Grade II and Grade II* restoration — securing listed building consent, matching original fabric, and adapting period homes to the way people live now without losing what makes them worth keeping.
Whole-house renovation. Major renovation of prime and period London houses, taken end to end — one team, from first survey and design through to the final coat.
Structural & complex work. The projects that defeat a general contractor: sensitive underpinning, basements beneath historic homes, structural stabilisation of listed buildings — handled by our own structural teams, never subcontracted.
Design & planning. Architecture, interior design and planning consultancy, in-house — including a 100% record on planning consents across central and south-west London.
Twenty years of these projects, across London’s prime and period housing — see the portfolio.
Selected projects
- Kensington Gate, W8 — Grade II*
Full renovation of a substantial period house, including planning and listed building consents and a major basement extension.
- Flanders Road, Chiswick, W4
A retrofit basement in waterlogged ground — formation level 1.5m below the water table. Built so tightly the pumps clear only condensation.
- Routh Road, Wandsworth, SW12
Whole-house renovation and basement to a large Edwardian family home.
- Marryat Road, Wimbledon, SW19
A very substantial family home extended and modernised, with a new basement swimming pool and a solar-thermal system to cut its running costs.
Their enthusiasm to create our perfect family home made OLBC the clear choice for us.

Unbelievably few snags on such a large project – we were also really impressed with the help and support we got after moving in.

Every enquiry starts with a Director
If you’re considering a project — a renovation, a listed building, something a general contractor has turned down — the first conversation is with one of our Directors, not a sales desk. They’ll tell you honestly what’s possible, what it’s likely to involve, and whether OLBC is the right firm for it.
We’ll only use your details to respond to your enquiry — see our privacy policy.
