A typical loft conversion in Wimbledon with LMB Group takes around six to eight weeks, depending on the scale and complexity of the project. For example, a straightforward Velux conversion in a property near Haydons Road might be completed in just over a month, while a larger dormer or hip-to-gable extension in the period homes around Wimbledon Park may take closer to eight weeks due to structural work and interior customisation. Our team follows a clearly phased schedule, beginning with site preparation and structural framing, followed by insulation, windows, plastering, electrics, and final finishes. We manage all trades in-house to minimise delays and maintain high quality throughout. Thanks to our experience working across the borough of Merton, we’re familiar with local suppliers, building control processes, and area-specific planning requirements. This local expertise allows us to keep your project running efficiently while delivering exceptional results within a realistic, agreed timeframe.

We handle all necessary documentation and liaise directly with local building control officers to ensure smooth inspections and approvals. Our experienced team keeps up to date with evolving legislation, including the latest guidance around energy efficiency and escape routes for multi-level homes.

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.

The estimated cost of a loft conversion in Wimbledon typically ranges from £40,000 to £85,000, depending on the type, size, and level of finish. For instance, a basic Velux conversion in a property near Wimbledon Chase may start from the lower end of that range, while a more complex dormer or mansard extension in the larger homes around Wimbledon Village could be at the higher end due to bespoke design features, en-suites, or premium finishes. At LMB Group, we provide a detailed, fixed-price quote after an on-site survey so you have complete clarity on what’s included—from planning and design to construction, insulation, plumbing, and electrics. We also take into account the architectural character of your area and ensure that all work aligns with local planning and building control requirements. Our goal is to deliver maximum space, value, and comfort while working within your budget and long-term property goals.

There are several types of loft conversions to choose from, including Velux (rooflight) conversions, dormer conversions, hip-to-gable conversions, and mansard conversions. The right option for your Wimbledon home depends on the existing roof shape, your desired layout, and whether you’re in a conservation area. For example, properties near Wimbledon Hill Road or close to Wimbledon Park often benefit from dormer or mansard conversions to maximise headroom and usable floor space. Meanwhile, homes with sloped hip roofs, particularly in areas like Southfields, are ideal candidates for hip-to-gable designs that unlock more volume. At LMB Group, we assess your home’s structural potential and planning constraints before guiding you toward the best solution for your lifestyle and property value goals. Our design-led approach ensures your conversion enhances both the appearance and functionality of your home, while also complying with Merton Council’s planning policies and Building Regulations.

A loft extension offers numerous benefits, especially for homeowners in sought-after areas like Wimbledon. It provides valuable extra living space—perfect for an additional bedroom, home office, or en-suite—without sacrificing garden space or requiring a move. Whether you’re in a Victorian terrace near Wimbledon Park Road or a detached property close to Wimbledon Common, a well-designed loft extension can significantly increase your property’s market value, often by 15–25%. It also enhances your home’s energy efficiency, thanks to updated insulation and ventilation systems that meet 2025 Building Regulations. In a competitive local property market, a spacious and well-finished loft room can set your home apart, making it more attractive to future buyers. At LMB Group, we create bespoke loft extensions that not only meet your current needs but also help you make the most of your home’s long-term potential—all while preserving the character and charm of your Wimbledon property.

In many cases, you don’t need full planning permission for a loft extension in Wimbledon, as most fall under permitted development rights. This means you can often proceed without a formal application, provided your design meets specific limits on height, volume, and materials. For example, a modest dormer extension on a home near Wimbledon Chase may qualify as permitted development. However, if your property is located in a conservation area, such as parts of Wimbledon Village or Merton Park, or if it’s a listed building, you will likely need full planning permission and must meet stricter design criteria. At LMB Group, we carry out a full assessment of your property and advise whether planning is required. If so, we handle the application and liaise with Merton Council on your behalf, ensuring your loft extension is not only compliant but also sensitive to the character and planning context of your local area.

The cost of a loft extension in Wimbledon typically ranges from £40,000 to £85,000, depending on the type of conversion, property size, and level of specification. For example, a straightforward Velux conversion on a property near Haydons Road might start around £40,000, offering a cost-effective way to add space and value. In contrast, a larger dormer or mansard extension on a period property in Wimbledon Village or close to Wimbledon Common could approach £80,000 or more, especially if it includes bespoke design features, high-end finishes, or an en-suite bathroom. At LMB Group, we offer fixed, transparent pricing with no hidden extras. Our quotes include everything from design and structural work to insulation, plumbing, electrics, and building regulation compliance. We also work closely with clients to align each project with their budget while ensuring the loft extension enhances both daily living and long-term property value in this premium part of London.

Yes, a loft extension can significantly improve your home’s energy efficiency, especially when constructed to modern standards. Homes in Wimbledon, particularly older properties near Wimbledon Hill Road or Dundonald Park, often have under-insulated or draughty loft spaces. When you convert a loft with LMB Group, we upgrade insulation to meet current Building Regulations, which helps reduce heat loss through the roof—a common issue in traditional homes. We install high-performance insulation, airtight membranes, and vapour control layers that not only retain warmth in winter but also help regulate temperatures in summer. This results in lower energy consumption and reduced heating bills. Many clients notice a noticeable improvement in comfort across the whole home after their loft extension is completed. By enhancing thermal performance at the top of the house, your property becomes more energy-efficient, environmentally responsible, and potentially more appealing to future buyers in Wimbledon’s competitive housing market.
