Conversions - General- 3 Jul 2023
We chose SWLBC to refurbish a two-bedroom flat. This entailed complete redecoration, replacement of the flooring with a new engineered wood floor, moving old and installing new electrical sockets and light switches, running some new piping and replacing the heating system with a more modern and efficient one. The quote from SWLBC was very competitive and we are really happy with the quality of the work. The flat is transformed and it looks terrific. Ben Toone who is the proprietor of the company is very professional and helpful. He was easy to contact and responded to our questions quickly and thoroughly. We met some members of his team during the works and they are hard working and competent. They also cleaned up the site beautifully after they had finished. Thank you Ben and your team. We are delighted with your work and highly recommend SWLBC.

Bathroom Fitting- 1 Jun 2025
I am really pleased with my new bathroom. I needed a partial refurb and new flooring due to a previous leaking shower. Landi did a great job fitting new taps, shower and sink in my bathroom. He was also able to advice me on the best sink and radiators and helped me to choose the right fittings when I was ordering. I didn't like the colour of the sealant and he redid it in another colour with no issues. He was efficient, friendly and completed the job in good time. Communication was always swift and I would be happy to recommend him to others and use him again for other jobs. Thanks Landi for great service.

We had the pleasure of working with Alfa Style Limited on our loft conversion and we can recommend them highly and without reservation. Their work is incredible, attention to detail outstanding – our build was done with care and precision. They turned up on time every day, worked incredibly hard and quickly. In addition, they were extremely clean and tidy in the workplace – they never left the worksite in disarray. This is the first time we have done such a big project – Ruslan, Slava and their team were amazing. They were brilliant at explaining what was going to happen, day by day, week by week and translated the more technical information! No question or query was too much. The service after the build had finished has also been great, calls to check everything is OK and any queries we have, they are only a phone call away. We have had so many compliments from family and friends who have seen the finished build … it has made a huge difference to our house, we could not be happier.

Bathroom Fitting- 20 Jan 2023
We highly recommend Mario & his team. They fitted a new kitchen & bathroom to a really high standard within a short, timeframe. They work hard, are friendly, professional & honest, my neighbour even commented on how considerate they were! Upon first meeting Mario we were impressed by how organised he was. He arrived on time with the description we’d posted on my builder & went through it methodically. We had A LOT of questions! He answered all of them & didn’t rush us. We received a competitive quote within a day as promised. It included everything we discussed & he quickly answered our follow up questions. We wanted an accurate idea of the cost of electrical work & Mario arranged for his electrician to come & inspect/quote before we’d appointed Mario the job. Our kitchen & bathroom is complicated, with lots of difficult angles. Damp, unlevel floor, unlevel windows, a low ceiling were uncovered in the bathroom. Mario did well to identify solutions, giving us expert advice. Pipes were neatly chased into the wall. Underfloor heating & LVT, tiling, grouting & painting all done to a very professional finish. He kept us informed of progress, checked our preferences & was patient when we had supply delays, finding ways to ensure the job finished on time enabling us to move from our temporary accommodation back home in time for Christmas. He promptly fixed some minor issues after the job finished. We highly recommend Mario & would use him again.

What experience do you have with similar extensions in West Norwood?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the West Norwood extension builder’s ability to deliver a result that meets your expectations.
