Lukasz and his team built a lower floor kitchen extension and downstairs WC for my wife and I. From start to finish, they were extremely professional and helpful. They were the perfect builders for first time renovators such as ourselves, guiding us through difficult decisions, while sticking religiously to their timescales. They began with helping us scope out the design, adding useful insight and advice. They then set to work, making our vision a reality. Their work ethic was superb, and we were ecstatic with the level of craftmanship exhibited. Like any building project, there were unforeseen costs and issues, but these were always handled very fairly and efficiently by Lukasz and his team. We are over the moon with the end product! I would (and have) recommend Lukasz to anyone looking to undertake building work.

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.

Loft Conversion- 1 Aug 2025
Sami completed our loft conversion to a high standard, on time and within the agreed budget. He was respectful, supportive, and very knowledgeable. He offered helpful input and practical suggestions throughout the project. When I came up with ambitious design ideas that would have cost a fortune, he provided honest, pragmatic advice and suggested smart, cost-effective alternatives that saved us a lot of money. He communicated clearly, was easy to work with, and kept everything running smoothly. He also recommended trusted tradespeople when needed, all of whom did excellent work. In addition to the loft, Sami and his team completed other jobs around the house with the same high standard and care. I wouldn’t hesitate to recommend him — reliable, skilled, and genuinely committed to quality. A fantastic builder who takes pride in his work and delivers results you can trust. We’re absolutely delighted with everything he’s done.

We needed a rear extension built with an internal courtyard. From day one when we first contacted Mert to get a quote he was professional and easy to talk to. His quote was good value for money. During the job he and his team were approachable, careful with our property and always easy to talk to and answer questions we had. The work Mert did was fantastic and our neighbours have already gone on to use him. We will get him back again for more work and highly recommend him.

I had the pleasure of working with Romeo and his team on my kitchen renovation, and I couldn't be happier with the results! From start to finish, his work was great. The kitchen looks fantastic, and they even finished the project ahead of schedule! Romeo and his team were very professional, always on time, and always kept me updated on the progress of the project. They also kept the flat clean and tidy every night, which made it much easier to live in the flat while the project was being done. I highly recommend them to anyone looking for a kitchen renovation!

I charge 60£ for a home visit and quote. This is to cover for my time and the website fee attributed to each add. If the jobs goes trough, this cost will be included in the final price. Hi, I am Flo, your local handyman with a decade plus of experience. Putting up a frame or building up an house extension, I can accommodate both and everything in between. If you have a project in mind i have a decade plus of experience that could come in handy so let’s get in touch. Yours sincerely, Florentin.

What experience do you have with similar extensions in Wandsworth?
