Local knowledge of Harlesden's Victorian streets and its conservation area, from first feasibility conversation through to a finished project.

Living and Building in Harlesden

Harlesden grew from a village into a busy Victorian town centre, still marked by its Jubilee Clock and surrounded by streets of Victorian villas and terraces.

Diagram X brings AEC (Architecture, Engineering and Construction) together for homeowners across an area where renovation and extension offer real value and where new housing is planned through its neighbourhood plan.

Planning in Harlesden

The Harlesden Conservation Area, designated in 1994, was extended in 2024 along Craven Park Road, Manor Park Road and Park Parade, and the council's Local Plan highlights the setting of the conservation area.

Permitted development rights should be checked for the exact property.

Refurbishing in Harlesden

Across the area's Victorian houses and flats, most interiors have had little meaningful updating in decades, so refurbishment starts from open, light-filled layouts and modern performance.

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

Construction in Harlesden

Terraced streets, party walls and busy road frontages shape structure and logistics, alongside the usual party wall agreements.

We plan for these from the outset, so Harlesden's Victorian streets and its individual homes are both well served.
