Extensions- 28 Oct 2018
We appointed HWB to carry out a full refurbishment on our house, this involved re-gutting the interior and building an extension and loft conversion plus some landscaping in the garden. We spoke to many builders but finally appointed HWB based on their previous projects and professionalism. Appointing builders for any work is always difficult however we are delighted that we went with HWB. Throughout the project they have demonstrated high levels of professionalism, were very organised and worked to very high standards. They were collaborative throughout the whole project and kept us informed at every stage. As the project developed there were some changes made and HWB were flexible and open to new instructions made by us, as well as giving us valuable advice. Farag, Ayoub and the HWB team were always available to answer any questions and provided us with constant feedback on progress as well as identify new solutions to aid the development. They have a great team of workers who work to a high standard and are supervised throughout the project. We made the right decision going with HWB Construction and have no hesitation in recommending them.

Bathroom Fitting- 21 Apr 2026
Marcin and his team did a fantastic job on our bathroom rennovation. A very tight space and demanding request from me (difficult tiling and suite to install), Marcin and his experts gave me some great advice on how to approach the job and the quote provided was very fair for the work undertaken. I have been so impressed by the quality of the work at every step and the project stayed on time and on budget (a miracle!). All the team members were extremely polite, respectful and always on time with great work ethic. I will be using Marcin and his team for my next project no question. Thank you Marcin, Rad & Igor for all your work and kindness.

Extensions- 11 Jan 2018
This was our first project, and we were exceptionally fortunate to find Bujar. We're actually getting tired of hearing our family and friends tell us how lucky we are and how amazing he sounds. One of the most honest, trustworthy, and genuine people I've ever met. If I had a problem, he'd be one of the first people I'd call! In fact I did last week and he came to the rescue :) His team were all friendly, polite, conscientious and very tidy. They worked around us as much as they could, always making sure we had access to what we needed which sometimes meant it took them longer to work. Bujar is a perfectionist and is so proud of what he does, he made sure everything was done to a high standard - the estate agent who came round after we were done was impressed! His prices are very fair (better value than other quotes we got and much less time). We couldn't believe it was done in the 3 months he said it would take, and we managed to fit in a few extra bits and pieces after that. He was so helpful throughout, took all project management on and didn't bother us unless an important decision needed to be made. He drove us around all over the place to sort kitchens, bathrooms, etc. and gave us really helpful advice throughout the process. Highly recommend him and his team. I can't imagine ever wanting to look for another builder unless I had to - something that is quite common amongst Bujar's clients. We are extremely pleased with everything about our new house.

Extensions- 29 Apr 2026
Heera, Jagthar and team was my first personal experience with builders. Let me tell you, it was a pleasure to have them do our porch and other renovations in the house. They are so courteous, hard working and provided a great service. Firstly, I had a comprehensively written quote breaking down all of the steps required. Heera then ensured to keep me in the loop of any developments/any changes of plan required, outlining the reasons why and options, making it easy to understand and work together to completion. Their finish was to a high quality and they would always go the extra step to ensure this. I highly recommend AS Builders for any job and will definitely use them again in the future, and would recommend to my friends and family also. If you are considering them, grab a free quote and go from there... That's what I did! Thank you AS Builders for our renovations!

Questions to ask local loft conversion companies in Knightsbridge

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 Knightsbridge?

A local loft conversion company in Knightsbridge 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 Knightsbridge 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 Knightsbridge 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 Knightsbridge

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 Knightsbridge before agreeing to start the work.

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

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 Knightsbridge 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 Knightsbridge loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
