Loft Conversions Bromley

A typical loft conversion in Bromley with LMB Group usually takes between 4 to 6 weeks, depending on the size and complexity of the project. Whether your property is tucked away in the quieter residential streets of Shortlands, along Beckenham Lane, or near the bustling hub of Bromley South, our team approaches each build with efficiency and precision.

We begin by taking the time to fully understand your vision and requirements during a detailed planning and design phase. From there, our experienced designers and craftsmen work to ensure that your loft conversion is completed with minimal disruption to your everyday life. We know how important it is to maintain your routine—especially in family-oriented areas like Hayes and West Wickham—so we keep the process as smooth and stress-free as possible.

Throughout the build, we maintain clear and open communication, updating you on progress and any changes along the way. Our priority is delivering a high-quality, beautifully finished loft space on time, without ever compromising on workmanship or detail.

Yes, absolutely. At LMB Group, full compliance with local building regulations is at the heart of everything we do. Every loft conversion we carry out in Bromley—whether it’s a family home in Chislehurst, a period property in Bickley, or a semi-detached house near Bromley North Station—is designed and built to meet or exceed the standards set by Bromley Council and UK building control guidelines.

We’re well-versed in the local requirements, covering essential aspects such as fire safety, structural integrity, sound insulation, energy efficiency, and access. From the outset, our experienced team ensures that all plans are drawn up with regulatory compliance in mind, helping to avoid costly delays or complications further down the line.

By working with LMB Group, you can rest easy knowing your loft conversion isn’t just beautifully crafted—it’s structurally sound, legally compliant, and built to last. We take pride in delivering safe, efficient, and future-proof living spaces across every corner of Bromley.

The cost of a loft conversion in Bromley with LMB Group depends on a number of factors, including the size of your existing loft space, the complexity of the design, the materials chosen, and any bespoke features you’d like to include. Whether you’re based in a traditional terrace near Sundridge Park, a semi on Ravensbourne Road, or a detached property in Bickley, we tailor each project to suit both the home and the homeowner.

To give you a clear idea of costs, we offer a free, no-obligation consultation, where we assess your space, listen to your ideas, and provide a detailed, transparent estimate. Our quotes cover all aspects of the project—from structural work and insulation to staircases and finishes—so there are no hidden surprises.

We’re committed to delivering exceptional value, combining quality craftsmanship with cost-effective solutions. With LMB Group, your loft conversion is an investment that not only adds space, but also enhances the long-term value and livability of your Bromley home.

At LMB Group, we offer several types of loft conversions to suit the wide range of property styles found across Bromley. Whether you live in a classic Edwardian semi on Highfield Road, a 1930s detached home in Shortlands, or a Victorian terrace near Bromley South, we’ll help you choose a loft conversion style that works for your space, budget, and lifestyle.

Velux (or rooflight) conversions are a great option for homes that already have generous roof height, particularly in areas like Hayes and Chislehurst, where retaining the existing roofline can preserve character and reduce costs. Dormer conversions, one of the most popular choices in Bromley, are ideal for adding headroom and usable floor space, especially in family homes near Widmore Green.

If you’re looking for a larger transformation, mansard conversions are perfect for maximising space—often used in areas with more generous planning allowances. Meanwhile, hip-to-gable conversions are ideal for properties with hipped roofs, commonly found in Bickley and West Wickham.

Our team will carry out a full assessment of your home, taking into account your goals, the existing roof structure, and any planning constraints. From there, we’ll recommend the most suitable option to ensure your loft not only adds space but also blends seamlessly with the character of your Bromley home.

A loft extension is one of the most practical and rewarding ways to enhance your home in Bromley. At LMB Group, we’ve worked on properties across the borough—from family homes in Beckenham and Bickley to period terraces in Shortlands—and we’ve seen first-hand the transformative benefits a well-designed loft space can offer.

One of the biggest advantages is the ability to gain valuable extra space without sacrificing your garden, which is particularly important in areas like Bromley South or Sundridge Park, where outdoor space may be limited. Whether you need an additional bedroom, a light-filled home office, or a playroom for the kids, a loft extension allows you to expand upwards instead of outwards.

Not only does it improve everyday functionality, but it can also add significant value to your property—often by as much as 15–20%. With the flexibility to tailor the design to your lifestyle, a loft extension offers a smart, future-proof investment that makes full use of your existing footprint.

Whether you need planning permission for a loft extension in Bromley depends on the type of property you own and the scale of the proposed work. In many cases, especially for homes in areas like Hayes, West Wickham, and Bromley Common, loft extensions fall under Permitted Development Rights, meaning you won’t need formal planning permission—provided the design meets specific criteria regarding size, height, materials, and roof alterations.

However, if your property is a flat, located in a conservation area like parts of Chislehurst or Shortlands, or is a listed building, those rights may not apply. Similarly, more substantial designs—such as a large mansard or hip-to-gable extension—might require formal approval.

At LMB Group, we always recommend speaking with our team early in the process. We’re well-versed in Bromley Council’s planning policies and can advise you on what permissions you may need. If an application is required, we’ll handle the process for you to ensure your loft extension meets all legal requirements and moves forward without unnecessary delays.

The cost of a loft extension in Bromley can vary significantly depending on the size of the space, the type of conversion, the materials selected, and any bespoke design features. Whether you’re planning a straightforward Velux conversion in Hayes, a dormer extension in Beckenham, or a more complex mansard design for a property in Bickley, each project is priced according to its individual scope.

At LMB Group, we offer a free, no-obligation consultation where we visit your home, assess your loft space, and discuss your ideas. From there, we provide a detailed quote that breaks down the full cost—so you can see exactly where your investment is going, from structure and insulation to finishes and fixtures.

We pride ourselves on delivering excellent value for money. Our pricing is transparent, competitive, and tailored to your budget, with no hidden extras. With decades of experience working across Bromley, we’re here to help you make the most of your home—both in terms of space and long-term value.

Yes, absolutely—a loft extension can be a smart way to boost your home’s overall energy efficiency, especially when it’s done properly. At LMB Group, we make energy performance a key focus in every loft extension we deliver across Bromley, from period homes in Shortlands to family houses in West Wickham.

Modern loft extensions offer the opportunity to install high-performance insulation in your roof, walls, and floors—areas where traditional properties often lose the most heat. This helps to maintain a more stable indoor temperature year-round, cutting down on heating costs in winter and keeping things cooler during summer.

We also use energy-efficient glazing, such as Low-E roof windows, and can incorporate sustainable materials where possible. Whether you’re near Bromley South Station or overlooking the green spaces around Norman Park, our aim is to create lofts that are not only stylish and functional but also environmentally responsible. The result is a more comfortable home, lower energy bills, and a smaller carbon footprint.
