Architects and Engineers in Harefield
Local knowledge of Harefield's Green Belt village setting, canal-side hamlets and protected historic centre, from first feasibility conversation through to a finished project.
Living and Building in Harefield
Harefield sits at the northern edge of the borough in the Colne Valley, a village of cottages and larger rural homes surrounded by countryside and the Grand Union Canal.
Diagram X brings AEC (Architecture, Engineering and Construction) together for Harefield homeowners, from careful village-centre alterations to extensions on larger plots.

Planning in Harefield
Harefield Village and Black Jacks and Copper Mill Lock are conservation areas, so the historic centre and the canal-side buildings are carefully controlled.
Much of Harefield is Green Belt, within the Colne Valley Regional Park, so proposals are judged against Green Belt policy and permitted development rights should be checked property by property.

Refurbishing in Harefield
Harefield's cottages, older village houses and larger rural homes call for refurbishment that raises light and thermal performance while respecting what is genuinely worth keeping.
A worthwhile period feature earns its place when retained, but a confidently modern result is always the starting assumption.

Construction in Harefield
Rural access, narrow lanes, ground near the canal and river, and sensitive Green Belt sites affect plant access, drainage and sequencing.
We plan for these early, so a Harefield project is delivered with care for its setting.
