Kitchen Renovation & Extensions | London & Home Counties

Kitchen renovation is J&D Building’s most requested service — and it’s easy to understand why. The kitchen is where London families actually live, and a poorly designed one affects daily life every day. We’ve renovated hundreds of kitchens across London, Surrey and Kent, from tight galley kitchens in Peckham flats to full rear-extension open-plan builds in Surrey. We’re builders first, not kitchen showroom salespeople. That means we give you honest advice about what your kitchen actually needs structurally — before you spend money on units and worktops.

Kitchen Extensions – combine the renovation with extra space

The most transformative option: extend your kitchen into the garden and renovate at the same time. We handle everything — groundworks, steel beam installation, roofing, glazing, bi-fold doors, plumbing, electrical and kitchen fit-out — under one quote, with one point of contact.

  • Single-storey rear extensions: popular across South London terraces
  • Side return extensions: maximise width in Victorian semis and terraces
  • Open-plan kitchen-diner designs with bi-fold or sliding doors

Full Kitchen Refits — new layout, no extension

If your kitchen is the right size but the wrong layout — or simply worn out — a full refit redesigns the space without structural work. We project-manage the whole process: remove the old kitchen, replumb, rewire, new units, worktops, tiling, and decoration. Most full refits take 2–3 weeks.

Period Property Kitchens — Victorian and Edwardian houses

South London’s Victorian and Edwardian terraces have specific structural characteristics: chimney breasts, load-bearing rear walls, and narrow floor plans. We know how to work with these — and how to open them up without compromising structural integrity. We’ve removed more rear walls in Croydon, Sutton and Bromley than we can count.

Approximate costs (London & Home Counties, 2026)

A basic kitchen refit (new units, worktops, appliances, tiling) typically costs £8,000–£20,000 depending on kitchen size and specification. A kitchen extension combined with renovation typically starts at £35,000 for a single-storey addition. We provide itemised written quotes — there are no hidden costs.

A straight refit (no structural work) typically means 2–3 weeks without a working kitchen. We sequence the work to get plumbing and basic appliance connections operational as quickly as possible. For extensions, the kitchen is usually operational within 5–6 weeks.
