Architects and Engineers in Hornsey
Local knowledge of Hornsey's medieval village core and its late Victorian streets, from first feasibility conversation through to a finished project.
Living and Building in Hornsey
Hornsey began as a village along its High Street, where the 15th-century tower of the old St Mary's church still stands as the oldest building in the area.
Diagram X brings AEC (Architecture, Engineering and Construction) together for homeowners across the late Victorian terraces and larger villas that spread around it after the railway arrived in 1850.

Planning in Hornsey
The Hornsey High Street Conservation Area, designated in 1980, protects the village core, while the Hornsey Water Works and Filter Beds and Hillfield conservation areas lie close by.
Haringey's window-and-door Article 4 directions do not apply here, so each scheme depends on its exact conservation area and listing status.

Refurbishing in Hornsey
Behind late Victorian frontages, 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 Hornsey
Terraces built by speculative builders and larger Warner Estate villas call for different structural approaches, and party wall agreements are routine.
We plan for these from the outset, so Hornsey's layered history and its individual homes are both well served.
