Home Extensions in London
Expand Your Space, Elevate Your Life..
About The Service
At Loftnix Developments Ltd, we understand that sometimes your house needs to grow with you.
Whether you’re expecting a new family member, working from home, or simply craving more space to breathe, a home extension is one of the most transformative investments you can make. We design and build stunning, seamless home extensions across all London postcode zones – SE, SW,N, NW, E, W, EC, and WC.
From light-filled kitchens to spacious open-plan living rooms, from private home offices to playrooms that echo with laughter – we extend more than space. We extend life.
Why Choose a Home Extension?
Moving house in London can cost tens of thousands of pounds in fees, taxes, and stress. With a home extension, you get the space you want, right where you are.
Our extensions:
- Increase the size and usability of your home
- Add value (10-20%) to your property
- Improve layout, natural light, and flow
- Avoid the cost and stress of moving
- Modernise older layouts for 21st-century living
Extension Types We Specialise In
1. Rear Extensions
Extend outwards from the back of your home into your garden. Perfect for adding a new kitchen, dining space, or large family room. Popular in SE and E London zones.
2. Side Return Extensions
Use the narrow alleyway on the side of many Victorian homes to extend your kitchen or create more width. Common in SW, N, and NW London.
3. Wrap-Around Extensions
Combine rear and side return into a large, L-shaped build. Ideal for dramatic open-plan spaces that connect kitchen, dining, and living in one flow.
4. Double-Storey Extensions
Build both ground and first floor extensions for bedrooms upstairs and living space below. Ideal in detached and semi-detached homes in North and South London.
5. Basement Extensions
Create new lower-ground floors under your existing house. Great for extra bedrooms, gyms, media rooms – especially where outdoor space is limited.
Our Extension Process - Seamless from Start to Finish
Step 1: Free Home Visit & Assessment
We begin with a no-obligation visit where we listen, measure, assess, and advise. We look at access, light, structure, and potential.
Step 2: Design & Architecture
We handle everything: floorplans, 3D visuals, structural engineering, and planning permissions. If you already have an architect, we work as a team.
Step 3: Quotation
We send a clear, fixed-price quote with all materials, labour, and timelines itemised – no hidden costs, ever.
Step 4: Build
Our expert builders handle groundworks, brickwork, steels, roofing, plumbing, electrics, and all finishings. We work clean, respectfully, and on time.
Step 5: Handover
After a full clean and inspection, we walk through your new space with you. Every detail is checked and finished before sign-off.

What Clients Say
Common Questions
Expand Your Space, Elevate Your Life..
Do I need planning permission?
Many extensions fall under permitted development. We’ll advise based on your postcode and property type.
How long does it take?
Most ground floor extensions take 8-12 weeks. Larger or two-storey builds take longer. We give full schedules before we begin.
Can you match my brickwork?
Yes. We source bricks that blend with your original structure for a seamless finish.
What's included?
Everything. Foundations, structure, plaster, electrics, plumbing, finishes – unless you ask us to exclude something.
