Local Handyman | Loft Conversion and  Home Extension in Bromley. London

Handyman Services in London, Bromley & Beckenham

Alongside our larger building projects, Thima Green Limited also offers a reliable local handyman service for homeowners in Bromley, Beckenham and the surrounding areas. We started the business as a handyman service, helping clients with repairs, home improvements and smaller building jobs, and that same practical, can-do approach remains part of what we do today. Whether you need help with general property maintenance, improvements or small works, you can rely on us for tidy workmanship, clear communication and a professional service from start to finish.

Create a bright new bedroom, home office or master suite without moving. We deliver loft conversions including dormer, hip-to-gable, mansard and Velux options, with careful attention to structure, insulation, stairs, fire safety and finishing. If needed, we can also arrange architectural drawings and structural calculations to support Planning and Building Regulations.

Home Extensions (Rear, Side Return & Wraparound)

If you need a bigger kitchen-diner or more living space, we build rear extensions, side extensions, side returns and wraparound extensions across Bromley and Beckenham. From groundwork and drainage to steelwork, roofing, windows/doors and interior finishes, we manage the full build and coordinate trades to keep everything running smoothly.

Outbuildings & Garden Rooms

Add a flexible space at the end of the garden with a garden room, gym, office, studio, playroom or summer house. We build durable, well-insulated outbuildings with electrics, lighting, flooring and finishes designed for year-round use.

Renovations, Refurbishments, Kitchens & Bathrooms

We improve and modernise homes with full refurbishments, kitchen renovations, bathroom installations and internal upgrades. Whether it’s updating a single room or transforming the whole property, we focus on quality workmanship, clean lines and a tidy site throughout.

Structural Alterations & Internal Reconfiguration

Opening up layouts often requires structural work done properly. We carry out structural alterations such as installing RSJs/steel beams, removing load-bearing walls (with the correct design), creating new openings and reconfiguring internal spaces safely and compliantly.

Loft Conversions & Extensions FAQs (Bromley & Beckenham)

Do I need planning permission for a loft conversion or extension?

Many loft conversions and some extensions can fall under Permitted Development, so planning permission isn’t always required. It depends on the size, location, roof changes, boundaries, and whether your property is in a conservation area. We’ll advise early on what’s likely needed for your home.

What types of loft conversion do you build?

We build Dormer, Hip-to-Gable, Mansard and Velux/Rooflight loft conversions. We’ll recommend the best option based on your roof shape, head height, budget and how you want to use the space.

What types of extensions do you build?

We build a wide range of home extensions in Bromley and Beckenham, including:

• Rear extensions (ideal for larger kitchen-diners)
• Side extensions
• Side return extensions (great for Victorian terraces)
• Wraparound extensions (rear + side return combined)
  We can also help with layouts, structural requirements and finishes to suit how you live.

Can you help with drawings, structural calculations and Building Regulations?

Yes. We offer a complete design-and-build service and can arrange architectural drawings, structural calculations, and documents needed for Building Regulations (and planning if required). This keeps the process coordinated and efficient.

How long do loft conversions and extensions take?

Timeframes vary depending on the scope and complexity. Smaller projects are quicker, while larger dormer/mansard lofts or wraparound extensions take longer. After a site visit and a clear scope, we’ll provide a realistic programme and expected timescales.

Will I need to move out during the works?

In most cases, homeowners stay in the property during loft conversions and extensions. There will be noise and disruption at times, but we focus on tidy sites and clear communication, and we’ll explain what to expect at each stage.

How much does a loft conversion or extension cost?

Costs depend on the design, size, structural requirements and finishes (for example, steelwork, glazing, kitchen/bathroom specs). After a site visit we’ll provide a free, no-obligation quotation with a clear scope of works.

Are you insured and do you offer a guarantee?

Yes — we’re fully insured and we stand behind our workmanship. We’ll confirm the relevant cover and any guarantees at quotation stage.
