Transform your home with a beautifully designed, expertly built kitchen extension from LXR Construction. We specialise in high-quality kitchen extensions across London, helping homeowners create more space, more light and a modern kitchen that works perfectly for everyday living. Whether you want a small kitchen extension, a side return, or a full wrap-around open-plan design, our team handles everything from concept to completion — including design, planning, structural work and full fit-out.

Why Choose a Kitchen Extension?

  • Add Space, Light and Value to Your Home – A kitchen extension is one of the most effective ways to improve your property. More space. Better flow. Brighter interiors. A carefully designed extension can immediately elevate how your home looks and functions.
  • Why London Homes Are Perfect for Kitchen Extensions – Many London properties — especially terraced and semi-detached homes — have untapped potential at the rear or side. Extending into this unused space creates room for open-plan layouts, floor-to-ceiling glazing and spacious dining areas that modern families love.
  • Small vs Large Extensions – Not every home needs a huge extension. Even a small kitchen extension can deliver dramatic improvements with clever design, natural light and smart storage solutions. Our team helps you understand what will work best for your property, budget and lifestyle.
