Serving Harrow and nearby West London areas

House Extensions in Harrow

A successful Harrow extension depends on resolving planning, structural design, drainage and access before work starts, then keeping the shell and internal fit-out under one coordinated programme.

What to establish before the quote

Rear and side extensions can involve planning permission or permitted development rules depending on the property and proposal. A site review is needed before D-Core can advise which route is likely to apply.

The construction sequence normally moves from surveys and design through foundations, drainage, structural openings, weatherproofing and internal finishes. Neighbour access and occupied-home protection should be addressed in the programme rather than left until work begins.
