We build house extensions, loft conversions and refurbishments in Northwood and Northwood Hills. The area is one of the greener, more spacious parts of Hillingdon, with larger homes on bigger plots.
Planning in Northwood
Northwood is in the London Borough of Hillingdon, and Hillingdon Council decides planning applications. Parts of Northwood are conservation areas, and some roads have special character protection, so permitted development may be limited. Parts of the area also border the Green Belt, which affects larger schemes.
Homes and typical work
Northwood has large detached and semi-detached houses, many from the interwar period, with mature gardens. Typical projects are a deep rear extension and an additional side extension, a loft conversion for a main bedroom suite, and a complete refurbishment of a larger house.
Points particular to Northwood
- Larger homes often have more complicated drainage, trees and boundaries, so the site visit covers them before a price is given.
- Check for tree preservation orders, which are common in leafy areas.
- Where a plot borders the Green Belt, the council looks closely at size, and a design that respects the original house has the best chance.
Frequently asked questions
Is Northwood a conservation area?
Parts of it are. Hillingdon Council’s map will show whether your road is covered.
Can I build a large extension on a big plot?
Possibly, but a large plot does not remove the limits. The rules still look at the size of the original house, and larger schemes usually need planning permission.
