Architects and Engineers in Southall
Local knowledge of Southall's historic Manor House, its distinctive cultural character, and its evolving town centre, from first feasibility conversation through to a finished project.
Living and Building in Southall
Southall's oldest surviving building is its Grade II* listed Manor House, built in 1587, now at the centre of a genuine heritage-led plan to become a hospitality training centre.
As a London AEC (Architecture, Engineering and Construction) consultancy, Diagram X brings its disciplines together for homeowners and businesses across one of London's most distinctive communities, shaped since the 1950s by its large Punjabi and Sikh population alongside the Grand Union Canal that first brought industry here.
Planning in Southall
Planning in Southall is guided by a 2024 town regeneration framework protecting and reusing key heritage assets, including the Manor House and the Grade II* listed Himalaya Palace Theatre, alongside planned major redevelopment such as the former Southall Gas Works site, now approved for thousands of new homes.
An Article 4 direction applies across the wider borough, so permitted development rights should never be assumed without checking the specific property first.
Refurbishing in Southall
Across the area's Edwardian terraces and post-war housing, 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 Southall
Construction in Southall benefits from being planned around both the area's active regeneration sites and its borough-wide Article 4 restrictions on individual properties, alongside the usual party wall agreements for Southall's Edwardian terraced housing.
We plan for both from the outset, so Southall's distinctive character and its individual homes are both well served.
