Kitchen Extensions in London

A well-designed kitchen extension can completely change how your home feels and functions. If you’re planning kitchen extensions in London, Decorators Builders delivers rear and side return extensions that create practical, open-plan space with a finish that feels integrated—not “added on”.

Kitchen extensions are often the centre of family life. That’s why we focus on proper planning, tidy site management and careful sequencing, so the build runs smoothly and the final result feels cohesive with the rest of the property.

Rear kitchen extensions

A rear kitchen extension is one of the most popular ways to increase ground-floor space, improve layout and bring more natural light into the home. It can create room for a larger kitchen, dining area, family space—or all three.

Rear extension work can include:

• Ground-floor extension build and structural works
• Steelwork and structural openings where required
• Roofing, insulation and weatherproofing
• Glazing options such as rooflights and large openings (spec-led)
• Internal fit-out and making good

Side return kitchen extensions

A side return kitchen extension is ideal for many terraced and semi-detached properties where a narrow side passage can be brought into the main footprint. This often unlocks a wider kitchen-diner layout and improves the flow of the ground floor.

Side return extension work may include:

• Infill extension to widen the kitchen area
• Structural alterations and steelwork where required
• Roofing upgrades and insulation
• Drainage considerations and practical detailing
• Finishes that blend with the existing home

Kitchen-diner and open-plan layouts

Most kitchen extensions are done to create a better layout, not just more space. We often build kitchen-diner extensions designed around everyday living: cooking, dining, and spending time together in one connected space.

Common layout goals include:

• Creating a kitchen-diner with better circulation
• Improving storage and worktop space
• Bringing in more natural light
• Adding practical zones (dining, seating, utility)
• Finishing the extension so it feels part of the original home

If you already have drawings, we can quote from plans. If you’re early stage, we can help you sense-check practical options and buildability.

What’s involved in a kitchen extension build

Kitchen extensions typically require careful sequencing so the home stays safe and manageable during the build. Works may include:

• Site setup and protection
• Foundations and structure (where required)
• Structural openings and steel installation (where required)
• Roof build-up, insulation and weatherproofing
• First fix services coordination (plumbing/electrics where required)
• Plastering, flooring, finishing carpentry and making good
• Final snagging and handover

Kitchen installation can be part of your wider refurbishment plan, depending on the project scope.

Kitchen extensions for occupied homes

Many clients stay in the home during a kitchen extension. Where practical, we phase the build and keep the site organised to reduce disruption. We’ll advise honestly on what to expect based on your layout, access and programme.
