The cost of a loft conversion in Kingston upon Thames can vary based on several key factors, including the size of your loft, the complexity of the design, the level of customisation, and the materials chosen. Whether you own a terraced property near Kingston Market Place, a semi-detached home in Norbiton, or a detached house in Coombe Hill, each project is tailored to suit your specific space and vision.

At LMB Group, we offer a free, no-obligation consultation, where we take the time to understand your goals, assess the structure of your home, and provide a detailed, transparent estimate. Our quotes cover everything—from structural changes and insulation to electrics, plumbing, and finishing touches—so there are no hidden extras or surprises.

We’re committed to providing excellent value for money, combining high-quality workmanship with solutions that suit your budget. A loft conversion with LMB Group is not just an upgrade in space, but a long-term investment that can significantly increase the value of your Kingston home.

At LMB Group, we offer a range of loft conversion types to suit the diverse homes found throughout Kingston upon Thames. Whether you’re in a period property near Richmond Road, a 1930s semi in Norbiton, or a more contemporary home in Surbiton, we can recommend a conversion style that complements your space and meets your specific needs.

Velux loft conversions are ideal if you’re looking to add natural light and ventilation without altering the existing roofline—perfect for properties that already benefit from generous head height. Dormer conversions are a popular choice across Kingston, offering excellent additional headroom and floor space, especially in homes with sloping roofs.

For those seeking maximum space, a mansard conversion is ideal. These are well-suited to larger detached or end-of-terrace homes, such as those around Coombe Lane. If your home features a hipped roof, common in Berrylands and New Malden, a hip-to-gable conversion can dramatically open up the loft space by extending the side of the roof vertically.

Our experienced team will assess your property, listen to your ideas, and guide you toward the most suitable conversion based on structure, planning requirements, and your goals. The result is a loft that enhances both your living space and your home’s original character.

A loft extension is one of the most effective ways to unlock extra space and add long-term value to your home in Kingston upon Thames. At LMB Group, we’ve worked on properties throughout the area—from charming period terraces near Kingston Station to spacious family homes in Coombe Hill—and we’ve seen the incredible transformation a well-planned loft can bring.

Rather than expanding out and sacrificing garden space, a loft extension allows you to build upwards, making full use of your property’s existing footprint. It’s an ideal solution for growing families or homeowners in need of an extra bedroom, home office, or even a self-contained suite.

Loft extensions can significantly boost your home’s market value, especially in high-demand areas like Norbiton, Surbiton, and Kingston Hill, where space is at a premium. Beyond functionality, they offer a chance to customise your home to suit your lifestyle—whether that’s a light-filled workspace, a relaxing retreat, or an entertainment room designed just for you.

Whether or not you need planning permission for a loft extension in Kingston upon Thames depends on your property type and the scope of the proposed work. In many cases, particularly for homes in areas like Norbiton, Berrylands, or Surbiton, loft extensions fall under Permitted Development Rights. This means you may not need formal planning permission, as long as the design complies with certain conditions around height, volume, and materials.

However, if your property is located in a conservation area—such as near Kingston Hill or Coombe Wood—or if you own a flat or listed building, those rights may not apply. Larger or more complex designs, like mansard or hip-to-gable extensions, may also require planning approval.

At LMB Group, we always advise clients to consult with our team early in the process. We have in-depth knowledge of Royal Borough of Kingston upon Thames planning policies and can manage the entire application process on your behalf, ensuring your loft extension meets all legal requirements and progresses without unnecessary delays.

The cost of a loft extension in Kingston upon Thames can vary widely depending on a range of factors, including the size and type of extension, the materials selected, and any bespoke design features. A simple Velux conversion in a home near Kingston Road will typically cost less than a large-scale mansard extension in a detached property in Coombe Hill or Kingston Vale.

At LMB Group, we offer a free, no-obligation consultation to assess your property and understand your needs. Based on this, we provide a detailed and transparent quote that clearly outlines each stage of the work—so you always know exactly where your money is going.

We’re committed to offering high-quality results at a fair and competitive price. Whether you’re in Norbiton, Surbiton, or near Richmond Park, we’ll tailor the project to your space, goals, and budget—ensuring your loft extension delivers real value while enhancing your home and lifestyle.

Yes, a loft extension can absolutely improve your home’s energy efficiency—especially when designed and built with modern standards in mind. At LMB Group, we prioritise eco-friendly construction in every loft extension we undertake across Kingston upon Thames, from homes in Norbiton and Surbiton to the leafy residential streets of Coombe and Kingston Hill.

By converting your loft, you’re able to integrate modern insulation materials into the walls, roof, and flooring—dramatically reducing heat loss in winter and keeping your home cooler in summer. This improved thermal performance can lead to noticeable savings on your energy bills and a more comfortable living environment year-round.

We also offer energy-efficient glazing, Low-E roof windows, and the use of sustainable materials, all of which contribute to reducing your property’s carbon footprint. Whether you’re focused on cutting costs, supporting sustainability, or simply enhancing your home’s comfort, a thoughtfully designed loft extension can be a smart, energy-conscious upgrade for your Kingston home.
