London properties come in all shapes, from Victorian terraces to 1930s semis and modern homes, so the best single storey house extension is the one that suits your layout and planning constraints. Popular options include rear extensions to create a larger kitchen and dining area, side return extensions to unlock wasted alley space, and wrap-around ground floor extensions for maximum footprint. We help you choose glazing, rooflights, door styles, and internal layouts that improve natural light and flow, while keeping the design in keeping with your home. The goal is simple: create a space that looks right, feels bright, and works better for everyday life.
The cost of a single storey extension in London depends on the size, structure, access, specification, and the level of finish you choose. Groundworks, steelwork, drainage changes, and structural openings can influence the budget, as can premium items like large sliding doors, roof lanterns, underfloor heating, and bespoke kitchens. We keep pricing clear by explaining what is included, what is optional, and where you can spend for impact without wasting money. If you want a realistic budget range, we can assess your property, discuss your priorities, and guide you towards a build specification that matches your goals.
Many single storey extensions London projects can fall under permitted development, but it depends on your property, location, and the size and design of the extension. Conservation areas, flats, and certain layouts may require full planning permission. Even when planning is not required, building regulations still apply, covering structural safety, insulation, ventilation, drainage, electrics, and fire safety. We help you understand what you need from the start, coordinate drawings and submissions where required, and ensure the build is completed to the correct standards. This protects your investment and makes the process far less stressful.
A successful design and build single storey extension starts with listening. We begin with a consultation to understand your space, your ideas, and what you want the extension to achieve. Next, we develop a practical plan that considers layout, light, structure, and finishes, then we schedule the build with clear stages and realistic timelines. During construction, we manage trades, materials, inspections, and quality control, keeping the site tidy and communication clear. The result is a finished extension that feels like it has always belonged to your home, adding comfort, function, and long-term value.
You may need a Party Wall Agreement if the work affects a shared wall, involves excavations close to a neighbour’s foundations, or includes structural changes near the boundary. This is common in London terraces and semis.
Yes. Matching materials is a big part of making an extension look like it belongs. Where an exact match is not possible, we recommend design choices that look intentional and premium rather than “almost the same”.
In many cases, yes. Most homeowners stay in the property during a ground floor build, especially when the work is mainly at the rear. There will be noise, dust, and periods where access is restricted but we plan the sequence to keep disruption manageable, maintain safe walkways, and keep you updated so you can plan around the busiest stages.
