The cost of a loft conversion in Balham with LMB Group depends on several key factors, including the size and layout of your property, the complexity of the design, the materials you choose, and any bespoke features you’d like to include. Homes near Tooting Bec Common, Chestnut Grove, or along Balham High Road can vary widely in structure and style, so we tailor every quote to your specific space and needs.

To give you a clear picture, we offer a free, no-obligation consultation, where we assess your property, discuss your vision, and walk you through the options. Whether you’re considering a dormer conversion for a terraced home on Ramsden Road or a hip-to-gable for a semi-detached on Hydethorpe Road, we’ll provide a detailed, transparent estimate—no hidden fees, no surprises.

We’re committed to delivering excellent value for money, ensuring your loft conversion not only enhances your lifestyle but also adds real value to your property. With LMB Group, you get premium quality, honest pricing, and a team that genuinely knows Balham homes inside and out.

At LMB Group, we offer several loft conversion styles to suit the wide variety of homes found throughout Balham—from Victorian terraces near Ritherdon Road to 1930s semis around Cavendish Road and flats near Balham High Road.

Here’s a quick overview of the main types:

• Velux (Rooflight) Conversions – Great for homes with plenty of headroom already, like those around Weir Road. These are the least disruptive and most cost-effective, using skylights to bring in natural light without altering the roofline.

• Dormer Conversions – One of the most popular options in Balham. Ideal for adding both headroom and usable floor space—perfect for families in terraced properties around the Heaver Estate.

• Hip-to-Gable Conversions – Best for semi-detached homes with sloped (hipped) roofs, often found near Hydethorpe Road. This type extends the side of the roof to create a full-width gable wall, opening up valuable extra space.

• Mansard Conversions – A more extensive transformation, often used in conservation areas or for maximum space. Suitable for homes around Endlesham Road or where planning allows, as it involves altering the slope of the roof.

Choosing the right type depends on your property’s structure, your budget, and how you plan to use the space—whether it’s a master suite, home office, or even a rental unit. Our team will carry out a full assessment of your home, talk through your ideas, and guide you toward the best solution that blends functionality, planning feasibility, and aesthetic appeal.

Our goal? To deliver a loft conversion that not only adds space but feels like a natural extension of your Balham home.

A loft extension is one of the most effective ways to create valuable extra space in your Balham home, especially in an area where outdoor space can be limited. At LMB Group, we’ve worked on homes across the neighbourhood—from Victorian terraces near Hildreth Street Market to period properties along Balham Park Road—helping homeowners make the most of their unused attic space.

One of the biggest benefits of a loft extension is the ability to maximise your home’s existing footprint without needing to expand outwards. Whether you’re after an additional bedroom, a light-filled home office, or even a quiet retreat with views over Tooting Bec Common, a loft extension can deliver a beautifully functional new space tailored to your lifestyle.

In a desirable area like Balham, adding extra living space also has strong financial advantages. A high-quality loft conversion can significantly increase your property’s value, making it an excellent long-term investment. It’s a smart alternative to the costs and stress of moving—especially if you love your current home and want to stay close to local spots like The Exhibit or Chestnut Grove School.

Perhaps most importantly, a loft extension gives you the chance to create something that reflects your personal needs and style. From sleek modern finishes to traditional features that complement older homes, every detail can be customised. With LMB Group, you get a space that feels like a natural part of your home, designed with both practicality and aesthetics in mind.

Whether or not you need planning permission for a loft extension in Balham depends on your property and the type of extension you’re considering. In many cases, particularly for straightforward dormer or Velux-style conversions, the work can fall under Permitted Development Rights, meaning you won’t need to apply for formal planning permission. However, these rights come with strict conditions regarding height, volume, materials, and proximity to boundaries.

Things can be more complex if your home is within a conservation area—like the Heaver Estate—or if you’re in a flat or a converted property, where permitted development doesn’t usually apply. Larger mansard or hip-to-gable conversions, or projects that significantly alter the roofline, may also require approval from Wandsworth Council.

At LMB Group, we strongly recommend discussing your plans with our experienced team from the outset. We have in-depth knowledge of local planning rules specific to Balham and can advise you on whether permission is needed. If it is, we’ll take care of the application process on your behalf, ensuring everything is fully compliant and avoiding any unwanted delays or complications.

The cost of a loft extension in Balham can vary significantly depending on factors such as the size and type of extension, the materials selected, the complexity of the build, and any bespoke design features you choose to include. Whether you’re adding a modest Velux conversion in a top-floor flat near Balham High Road or a large-scale mansard extension on a period home near the Heaver Estate, each project is unique.

At LMB Group, we offer a free, no-obligation consultation to assess your property and understand your vision. Following this, we provide a detailed, transparent quote that breaks down every aspect of the cost—from structural work and insulation to finishes and fixtures—so you know exactly where your investment is going.

We pride ourselves on offering high-quality workmanship at competitive prices, and we’re committed to finding a solution that suits your budget without compromising on style or durability. With our expert guidance, you’ll get a loft extension that adds space, enhances your lifestyle, and increases the long-term value of your Balham home.

Yes, a loft extension can absolutely enhance your home’s energy efficiency—especially when it’s done right. At LMB Group, we prioritise eco-conscious building practices in all our Balham projects. Upgrading your loft space gives you the opportunity to install high-performance insulation and airtight construction methods, which can dramatically reduce heat loss during the colder months and help maintain a cooler indoor temperature in the summer.

Many older homes in Balham, particularly Victorian and Edwardian properties around Ritherdon Road or Cavendish Road, can benefit hugely from these modern energy-saving upgrades. By adding new, energy-efficient windows—such as double- or triple-glazed rooflights—you also increase natural light while minimising drafts and thermal bridging.

We also offer sustainable material options and can advise you on the best products to lower your carbon footprint without sacrificing style or comfort. Ultimately, a well-designed loft extension can make your home greener, more comfortable, and more cost-effective to run—all while adding valuable living space.
