A completed private residence in the Home Counties of England
Builders · London & the Home Counties

England’s considered private residences, built to endure.

A family-run building firm based in Ickenham, undertaking new-build homes, house extensions and the sensitive refurbishment of period properties across West London, Buckinghamshire and Hertfordshire. In continuous practice since 1995.

The practice

Quietly engaged upon England’s most discerning private commissions.

For three decades, MJ Design & Building has worked alongside private clients, country-house architects and family offices to realise residences of singular ambition. Our remit is narrow by design—new-build private homes, period-property refurbishment and substantial extension—and is delivered with the discretion such commissions properly require.

Many of our projects are undertaken under non-disclosure. References are furnished in confidence to qualified enquirers, and to their architects and surveyors, upon request.

A house is built but once. We treat every commission accordingly.

In our own words

Architecture is built by hand, by the men and women on site. Every other consideration follows from that one truth.

iii.

Construction

Delivered by our own site management, with regular reporting on progress, cost and quality from start on site to completion.

Handover

Snagging, certification and a complete health and safety file—the house delivered as it was promised.
