Extending a London home is more than just adding space; it's a precise craft dictated by the city's unique architectural landscape and planning constraints. At LACD Design and Build, we don't just construct; we solve the singular challenges of expanding in a historic city.
The Three Pillars of a London Extension:
1. The Heritage Dialogue
Whether it’s a grand Georgian house or a charming Victorian terrace, your extension must respect its roots. We specialise in the iconic Side-Return Infill, transforming that narrow alleyway into a luminous, full-width kitchen-diner, honouring the existing structure while introducing seamless modern design.
2. The Quest for Light
In tightly packed London, daylight is a luxury. Our designs focus on harvesting light through clever use of materials. Think expansive glazed walls that dissolve the boundary to the garden, and strategically placed roof lanterns that flood formerly dark interiors with sunshine.
3. The Power of Precision
London dictates precision—from navigating the Party Wall Act with neighbours to mastering complex Subterranean Conversions. This work requires a main contractor with a forensic eye. Our expertise in Bespoke Joinery is key here, maximising every precious inch with integrated storage and tailored features that truly make the space functional and unique to your life.
A London extension is a sophisticated answer to a simple need: to make a historic home perfectly fit a modern life. It’s an investment in space, light, and enduring quality.
