Architects and Engineers in Hanwell

Local knowledge of Hanwell's remarkable engineering heritage and its village-like residential conservation areas, from first feasibility conversation through to a finished project.

Living and Building in Hanwell

Hanwell is home to two genuinely remarkable pieces of engineering history, the Wharncliffe Viaduct, Isambard Kingdom Brunel's first major work for the Great Western Railway, built in 1836-37, and the Hanwell Flight, six locks on the Grand Union Canal now a Scheduled Ancient Monument.

As a London AEC (Architecture, Engineering and Construction) consultancy, Diagram X brings its disciplines together for homeowners across a place where significant engineering achievement sits comfortably alongside quiet residential streets.

Planning in Hanwell

Planning in Hanwell is shaped by several conservation areas, including Hanwell Village Green, Hanwell Clock Tower, and St Mark's and Canal, each protecting a distinct pocket of the area's character, from its village-like core to its canal-side terraces.

Individual listed structures, including lock keepers' cottages along the Grand Union Canal, add further heritage consideration for nearby work.

Refurbishing in Hanwell

Across the area's Victorian and Edwardian terraces, most interiors have had little meaningful updating in decades, so refurbishment here starts from bringing a home's light, layout and performance properly up to modern standards.

A genuinely worthwhile period feature earns its place when it's retained, but a confidently modern result inside is always the starting assumption.

Construction in Hanwell

Construction in Hanwell benefits from being planned around its several distinct conservation areas and the scheduled monument status of its canal locks, alongside the usual party wall agreements for its terraced housing stock.

We plan for both from the outset, so Hanwell's layered heritage and its individual homes are both well served.
