Architects and Engineers in Hillingdon
Local knowledge of Hillingdon's Metropolitan-line suburbs, canal-side towns and Green Belt villages, from first feasibility conversation through to a finished project.
Living and Building in Hillingdon
Hillingdon is London's second largest borough by area, home to 305,907 residents at the 2021 Census, stretching from Hayes and the Heathrow villages in the south to Northwood and Harefield on the Hertfordshire and Buckinghamshire edge.
Diagram X brings AEC (Architecture, Engineering and Construction) together for homeowners across a borough of interwar suburbs, historic village centres, canal-side towns and some of outer London's most generous plots.
Planning in Hillingdon
The borough has 31 conservation areas, from Eastcote Village, Ruislip Village and Ickenham Village to Old Uxbridge, Northwood's Frithwood and the canal locks along the Grand Union.
Much of Hillingdon is Green Belt, including land within the Colne Valley Regional Park, so protected trees, local designations and permitted development rights should be checked property by property.
Refurbishing in Hillingdon
Across the borough's interwar semi-detached and detached houses, most interiors have had little meaningful updating in decades, so refurbishment starts from bringing a home's light, layout and energy performance properly up to modern standards.
A genuinely worthwhile period feature earns its place when retained, but a confidently modern result inside is always the starting assumption.
Construction in Hillingdon
Heathrow flight paths, canal-side ground, large plots and mature trees all shape foundations, access and sequencing, alongside the usual party wall agreements.
We plan for these from the outset, so Hillingdon's varied suburbs and its individual homes are both well served.
