Construction in Harrow
Harrow (HA1) sits in North West London and is characterised by large detached and semi-detached houses, mansion blocks and Arts and Crafts stock, with substantial plots that support basements, pools and garden buildings.
Foxter works throughout Harrow and the surrounding HA1 postcode district, covering loft conversions, extensions, whole-house renovations, kitchens, bathrooms, basements, roofing, landscaping and commercial fit-out. Every project is run by one site manager with directly employed trades, so you have a single point of accountability from survey to snagging.
Wider streets and driveways generally allow on-plot storage and plant, which shortens programmes on larger projects such as basements and pools.
Before we quote we visit the property, measure it and write a scope of works. That matters more in Harrow than a per-metre average, because two houses on the same street can have completely different structure, drainage and consent constraints.

Consents and neighbours
We check permitted development rights, conservation area status and article 4 directions against your address before designing, and we serve party wall notices early so a two-month notice period never delays the programme.
Access and logistics
Skip permits, parking suspensions, protected internal routes, dust screens and agreed working hours are planned and priced before we start in Harrow — not added later as extras.
Price and programme
A fixed price against a written scope, with staged payments tied to milestones. Our instant quotation tool applies a North West London area factor so the indicative figure reflects local rates.
