Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.

Loft Conversion- 26 Nov 2020
I would highly recommend Kaca Constrution, Elson and his team were extremely professional, polite and the work was carried out to an excellent standard. I am extremely pleased with the result! I heavily researched builders before choosing Kaca Construction. The service was brilliant! The team always arrived on time and completed each stage of my project perfectly. This was the first building project that I have done (a loft conversion - hip to gable with dormer). Elson helped so much – from project planning, to connecting me with reliable suppliers - his advice was always reliable, clear and priceless. Elson was also very flexible, he always listened and tailored the project to my specific needs. I found him to be very knowledgeable and experienced. I highly recommend Kaca Construction and would definitely work with them again in the future. Excellent service and top quality work!

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.

Conversions - General- 3 Sep 2025
Big refurb of 1650 sq ft flat, plus building 2 additional ensuites. Initial quote seemed reasonable but then once in, costs started to rise exponentially. Some work was done well, like the building component and flooring, but finishing was poor. Painting, particularly of internal doors, was done poorly, without removal of fittings first, so lots of overpainting and insufficient prep and coats. Regrouting and redecoration of front and rear patios was done poorly, with weeds already poking through. There was damage to existing bathtubs and WCs by not protecting surfaces and pouring waste materials down the pan. Everything was an argument with constant demands for more money e.g. front door only painted one side as the other side not included under "paint door". Lots of "snagging" - I only have manual on/off control of heating and hot water as "smart" thermostat won't connect, there are odd water pressures through some fixings...and now there's a leak under one of the WCs...

Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!

Questions to ask local loft conversion companies in West Kensington

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 West Kensington?

A local loft conversion company in West Kensington 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 West Kensington 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 West Kensington 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 West Kensington

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 West Kensington before agreeing to start the work.

Do I need planning permission for a loft conversion in West Kensington?

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