Architects and Engineers in Pinner
Local knowledge of Pinner's medieval village core and its Metroland suburb, from first feasibility conversation through to a finished project.
Living and Building in Pinner
Pinner's High Street is a medieval village street lined with listed buildings, and the arrival of the Metropolitan Railway in 1885 gradually turned the village into a suburb that boomed as Metroland in the 1930s.
Diagram X brings AEC (Architecture, Engineering and Construction) together for homeowners across both the village core and the interwar streets around it.

Planning in Pinner
Pinner has more than ten conservation areas, including Pinner High Street (designated 1968), Pinner Hill and the 1930s Pinner Road area, home to the Art Deco Pinner Court.
Article 4 directions apply to parts of the village, so permitted development rights should be checked property by property.

Refurbishing in Pinner
Across the area's interwar houses and older village properties, 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 Pinner
Listed neighbours in the village core, mature trees and interwar semis with hipped roofs each need a different approach, alongside the usual party wall agreements.
We plan for these from the outset, so Pinner's layered history and its individual homes are both well served.
