Transform your home with a beautifully designed, expertly constructed pitched roof extension from LXR Construction. We specialise in high-quality pitched roof extensions across London, helping homeowners add valuable living space, increase natural light, and elevate the architectural character of their homes. Whether you want a single-storey pitched roof extension, a vaulted ceiling kitchen extension, or a complete redesign that blends seamlessly with your existing property, our team manages every stage — from concept and planning to structural engineering and full interior fit-out.
Why Build a Pitched Roof Extension?
- Enhance Space, Light & Character – A pitched roof extension instantly adds height and presence to your home. The sloping roofline creates opportunities for vaulted ceilings, rooflights, and a bright, open atmosphere that feels larger and more inviting than standard flat-roof designs.
- Superior Insulation & Energy Efficiency – The structure of a pitched roof makes it easier to incorporate high-performance insulation, natural ventilation, and thicker roofing materials — helping you reduce heat loss and maintain comfortable temperatures all year round.
- Perfect for London Homes – Many London properties — Victorian, Edwardian, and semi-detached homes — benefit from pitched roof architecture. A pitched roof extension blends effortlessly with traditional building styles, enhances curb appeal, and increases long-term value.
- Longer Lifespan & Better Weather Protection – Pitched roofs shed water more effectively, reduce the risk of standing water and leaks, and typically last longer with less maintenance compared to flat roofs.

Our Step By Step Process To Building Your Pitched Roof Extension
1
Consultation & Design
We begin with an in-depth consultation to understand how you use your home, which areas you want to enhance, and the architectural style you’re aiming for. Our designers explore options such as vaulted ceilings, skylights, roof pitches, glazing, and how the new space should connect seamlessly with your existing layout. We then create a bespoke concept focused on light, space and functionality.
2
Planning & Approvals
Depending on the size and style, pitched roof extensions may require full planning permission. We handle everything — architectural drawings, planning submissions, structural engineering calculations, party wall notices and building regulations compliance — ensuring the project progresses smoothly with no delays.
3
Construction & Project Management
Our experienced pitched roof extension builders carry out the build with precision and care. A dedicated project manager oversees all phases including groundworks, structural steel installation, brickwork, roofing, insulation, skylights, windows, and interior works. You receive continuous updates throughout the build for clarity and confidence.
4
Completion & Interior Fit-Out
Once construction is complete, we finish your new space with flooring, lighting, carpentry, heating, kitchen or bathroom installations (if required) and full decoration. We then perform a thorough quality inspection and walk you through the finished extension to ensure everything meets our high standards.
How Much Does A Pitched Roof Extension In London Cost?
Costs vary depending on roof pitch, complexity, structural steelwork, glazing, and level of finish. As a guide:
£65,000 – £110,000+ for a standard single-storey pitched roof extension
£110,000 – £160,000+ for premium vaulted designs with skylights, bespoke joinery, or larger footprints

Will a Pitched Roof Extension Add Value to your home
Yes the additional space provided by any extension can be a real selling point. With a pitched roof extension you are effectively adding an additional room onto a house. For example, a medium sized pitched roof extension built onto a kitchen would allow you to have a large open plan kitchen/dining room which could free up space in other rooms in the house. This could increase your home’s value by as much as 10–15%, depending on size of the extension.
