The cost of a loft conversion in Wimbledon can vary based on several key factors, including the size of the loft, the complexity of the design, the materials you choose, and any bespoke features you’d like to include. Whether you’re in a period property near Wimbledon Village, a family home close to Haydons Road, or a 1930s semi in Merton Park, each project is tailored to the individual property and homeowner.

At LMB Group, we offer a free, no-obligation consultation where we visit your home, assess your existing loft space, and talk through your vision. Following this, we provide a detailed, transparent quote with a full breakdown of the costs—so you’ll know exactly where your investment is going from day one.

We believe in offering excellent value for money and work closely with each client to create cost-effective solutions that never compromise on quality. A loft conversion with LMB Group is not just about gaining space—it’s about adding real, lasting value to your Wimbledon home.

At LMB Group, we offer a range of loft conversion types tailored to suit the varied property styles found across Wimbledon. Whether you live in a period terrace near Wimbledon Broadway, a 1930s semi in Merton Park, or a detached home around Wimbledon Village, we’ll help you choose the right conversion to make the most of your space.

Velux conversions are a great option for homes with sufficient existing head height, providing natural light and ventilation without altering the roofline—ideal for quieter conservation areas or homes near South Park Gardens. Dormer conversions are a popular choice in Wimbledon, particularly for mid-terrace homes, as they offer increased headroom and practical living space.

If you’re looking for maximum floor space, a mansard conversion is ideal—especially for larger or end-of-terrace homes near Wimbledon Park. For properties with a hipped roof, commonly found in areas like Raynes Park, a hip-to-gable conversion extends the roofline and creates a more usable layout.

Our experienced team will carry out a full assessment of your home and guide you through the best options based on your layout, budget, and planning constraints. We focus on creating lofts that are functional, beautifully finished, and in harmony with your home’s original character.

A loft extension is one of the smartest ways to expand your living space in Wimbledon without sacrificing your garden or navigating the hassle of moving. At LMB Group, we’ve transformed homes across Wimbledon Village, Raynes Park, and Southfields, helping families unlock the potential of their unused attic space.

By extending upwards, you can add a spacious new bedroom, home office, or even a self-contained suite—ideal for growing families or flexible modern living. In high-demand areas like Merton Park or near Wimbledon Chase, where floor space is valuable, a loft extension is a cost-effective way to gain more room while adding significant resale value to your property.

Loft extensions also offer incredible scope for personalisation. Whether you want built-in storage, skylights, or an en-suite bathroom, the space can be tailored to suit your lifestyle. The result is a beautifully integrated, practical addition that elevates both your home and the way you live in it.

Whether you need planning permission for a loft extension in Wimbledon depends on the scope of your project and the type of property you own. In many cases—especially for homes in areas like Merton Park, Raynes Park, or near Wimbledon Chase—loft extensions fall under Permitted Development Rights. This means you can proceed without formal planning permission, provided the design meets specific criteria for height, volume, and external alterations.

However, if your home is in a conservation area, such as parts of Wimbledon Village or South Park Gardens, or if it’s a listed building, you may need to apply for full planning permission. Larger-scale extensions or roof alterations, like mansard or hip-to-gable conversions, may also trigger the need for formal approval.

At LMB Group, we’re highly experienced with Merton Council’s planning regulations and can guide you through the process from start to finish. We’ll assess your property, advise on what permissions—if any—are required, and manage any applications on your behalf to ensure your project runs smoothly and stays compliant.

The cost of a loft extension in Wimbledon can vary depending on several factors, including the size and complexity of the build, the materials you choose, and any bespoke design features you’d like to incorporate.

Yes, a loft extension can make a real difference to your home’s energy efficiency—especially when built with modern materials and insulation techniques. At LMB Group, we prioritise eco-conscious design in all our projects across Wimbledon, from character properties near Wimbledon Common to family homes in Raynes Park or Southfields.

Converting your loft offers the perfect opportunity to install high-performance insulation, significantly reducing heat loss through the roof—one of the most common sources of energy inefficiency in older homes. As a result, your home stays warmer in winter and cooler in summer, leading to lower energy bills and improved year-round comfort.

We also offer energy-efficient glazing, Low-E roof windows, and can recommend sustainable building materials where appropriate. Not only does this help reduce your carbon footprint, but it also enhances the overall performance and value of your property. With LMB Group, your new loft space won’t just look fantastic—it’ll work smarter for your home and the planet.
