Harrow is family-home territory — the inter-war semis of Pinner, Kenton and Rayners Lane, the period streets around Harrow on the Hill, and pockets of new apartment development near the centre and Wealdstone. Kojo Construction builds across the borough and the wider North West London suburbs: developments and conversions for investors, and the extensions, loft conversions and whole-house renovations that growing families take on. Every trade is ours, so there’s one team answerable for the result.
There’s no Harrow project on the board yet — so instead of stock photos, here’s the real thing: a cross-section of finished rooms and live sites from recent Kojo builds. It’s the standard of work, and the level of detail, we’d bring to a job in Harrow.
From a full apartment development to a side-return extension or a single family bathroom — the same in-house team handles it all across Harrow and North West London.
One contractor for the whole project. Across Harrow and North West London we take the role of main contractor on apartment developments, conversions and major home projects — coordinating demolition, structure, every trade and Building Control — so you have a single point of contact and a single programme from start to handover, not a site full of separate subcontractors.
Open up a ground floor, add a storey, divide a building into flats. We design and install steel beams, SFS framing and drylining for Harrow projects — the structural work behind knock-throughs, loft floors and new-build apartments.
ExploreHarrow’s inter-war semis in Pinner, Kenton and Rayners Lane respond brilliantly to a full refurbishment. We reconfigure, re-service and re-finish them top to bottom — keeping the character buyers love while adding the space and efficiency a modern family needs.
ExploreAlmost standard across Harrow’s semis, and ideal for a growing family. We build dormer, L-shaped and hip-to-gable lofts — new bedroom, en-suite and staircase — fully structural, insulated and signed off to Building Regs.
ExploreSafe, certified electrical and plumbing for Harrow homes and developments — full rewires, consumer-unit upgrades, heating systems, hot water and bathrooms, all tested and signed off to current standards.
ExploreDesigned, supplied and fitted. From a single family bathroom in Stanmore to kitchens across a development, we handle the demolition, services, tiling and installation — you get a complete room finished to a premium standard.
ExploreEngineered and solid wood, natural stone and porcelain, plastering, bespoke joinery and decoration — the interior finishing that gives a Harrow home its final, premium look.
ExploreFrom a borough-wide development to an extension on your own street, we’ll handle it as one team with one point of contact — first survey to final handover. Tell us about your Harrow project and we’ll put together a clear, no-obligation quote.
