Complete Home Renovation Specialists

Lofts, extensions, basements, kitchens and bathrooms — designed and built to the highest standard, across London.

Hamax Construction

Built on Craftsmanship. Backed by Experience.

Hamax Construction is a London-based building company specialising in complete home renovations. We work directly with homeowners from initial concept through to final finish — no subcontracting chains, no guesswork, just one accountable team managing your project start to finish.

Whether it’s a single loft conversion or a full house transformation, we bring the same attention to detail: honest quotes, realistic timelines, and a finish that looks as good in five years as it does on day one.

House Extensions

Rear, side-return and wrap-around extensions that add space and value without the stress of moving. Includes bi-fold and sliding door installations, like our recent projects.

Loft Conversions

Turn unused loft space into a stunning extra bedroom, home office or bathroom. We handle design, structural work, and building regulations from start to finish.

Bathroom Renovations

From compact en-suites to spa-style family bathrooms, we deliver full renovations with quality fittings, waterproofing done right, and a clean finish.

Kitchen Renovations

Bespoke, modern kitchens built around how you actually live — full strip-outs, re-wiring, plumbing, cabinetry and finishing, all managed by one team.

Basement Conversions

Dig deeper, live bigger. We convert and underpin basements into fully livable, damp-proof spaces — gyms, cinema rooms, guest suites and more.
