I had my double side and single rear L shape Extension which had kitchens and bathrooms with bedrooms. It was turnkey project and didn’t know them before but they are Pro Contractor as they got all planning permission approved with structural calculations. They completed work in time with high standard quality and regulations and got my certificates from council. I would recommend them as Pro builder all the time.

The job was a complete refurbishment of a one bed flat, including rewiring and re-plumbing. We would recommend Al and his team without any hesitation. From the very beginning and all the way to completion, we felt very lucky and fortunate to hire them. We found them to be very hardworking, conscientious and professional. The job was a difficult and complex one, but the team still completed within time and within budget. Al's advice made the whole process easier and we found him to be very trustworthy and honest. The end result was better than we originally hoped for and was done to a high standard.

Loft Conversion- 18 Feb 2024
I wanted to express my gratitude for the exceptional work done by Cool Dudes Construction on my loft and bungalow conversion project. Despite an initial estimate of 12 wks, it was completed to a high standard within 15 wks, with only a minimal 3-wk delay due to 3rd parties (window suppliers) and the holiday season. A complex project. Full rebuild of bungalow, which included hip to gable conversion, rear loft dormer, stair, ground floor extension and full ground floor rennovations (1st & 2nd fix). Mandeep and Balwinder tackled a complex design that involved the integration of steel beams and pillars. They coordinated with various suppliers and also helped me to order skylights, windows, and doors, ensuring timely delivery and installation to keep the project on track. Team always showed professionalism, ensuring that they were always punctual, tidy, and respectful. Commitment to completing the project on time was evident, they maintained open communication throughout. One +ve aspect was their willingness to work with a private building control company that i hired, which ensured compliance with regulations. Another +ve aspect of working with them was clear payment milestones in the agreement. Payment was made on completion of milestones, which provided transparency and reassurance throughout the project. Extremely satisfied with the build and would not hesitate to recommend Cool Dudes Construction to others seeking reliable and efficient building services.

Restoration & Refurbishment- 31 Aug 2015
We have had quite a bit of work on our property in the last few years and the final project was to be our bathroom with the focus around a beautiful copper bath which has been sitting in the spare room waiting to be installed for nearly a year. We needed a company that could deliver a very high standard of work at a competitive price. Top building were not only very fair and competitive but wonderfully detailed in their approach both in quoting and their workmanship which is second to none. Vladimir and team understood the project from day one – made a few trips before hand which built the relationship and made myself and my husband very comfortable with our decision to instruct Top Building. What I enjoyed most is that Vladimir made great suggestions and offered money saving advice. Nothing was too much trouble and I really felt the team got behind the project. The knowledge and expertise is of an exceptional level. We had a few odd jobs that needed to be done which the team (Evo and Dimitri) welcomed and efficiently completed. I very much appreciate the patience and flexibility shown by the team and Vladimir’s brilliant way of keeping us informed every step of the way. Bathroom was totally refurbished including new Walls, plastering, electrics, tiling and new boiler. It really has been a pleasure working with the team – I will most certainly be recommending them.

Loft Conversion- 10 Feb 2026
We had a great experience working with BS Loft Conversions on our L-shaped dormer loft conversion. Anxhelo was friendly, approachable and professional from the initial quote through to completion. We made a few changes as the build progressed, and he was always open to discussing options and finding sensible solutions. We found the original quote fair, and the additional items we added were also priced fairly. Anxhelo was generous with his time in offering advice on different aspects of the build, which we really appreciated. The team – Anxhelo, Klaidi, Henry and Jimmy – were on site consistently, worked hard, and are clearly experienced at what they do. At the end of each day, and at the end of each stage of the project, the site was always left very clean and well organised. Before choosing BS Lofts, we spoke to previous clients and heard positive feedback, which gave us confidence. Having now worked with them ourselves, we’re happy to recommend them to friends and family.

Questions to ask local loft conversion companies in Hammersmith

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Hammersmith?

A local loft conversion company in Hammersmith will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Hammersmith should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Hammersmith loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in Hammersmith

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Hammersmith before agreeing to start the work.

Do I need planning permission for a loft conversion in Hammersmith?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Hammersmith loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Hammersmith loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
