4.3 / 5 · 97 totalThey did work on our lots a few years back and it was great. Very prompt and on budget
A top company. They’ve done two jobs for me over past few years: kitchen side extension and most recently a loft extension. Great quality finish, great price, excellent workmanship. Very pleased. Happily recommend
Craig and the Design Team at South London Lofts provided a first-class service, guiding and supporting us through the planning application process for our loft conversion to our home in Camberwell. We would have no hesitation in recommending them.
Had our loft done recently by SLL. Craig was extremely helpful and patient for several years as we worked through acquiring the loft space and getting relevant consents from freeholders and council. Minda and his team who were responsible for actually building the project got the job done swiftly and as/when there were problems (inevitable in any project) solved them quickly. Minda had a good book of contacts to get electrics, carpentry, tiling and decoration done concurrently with the building. All the individuals (both at SLL and the external parties recommended by Minda) worked extremely hard and efficiently - we lived in the property during the works and everyone was friendly, respectful and made the experience so much easier than it could have been. Really pleased with our new bedroom and bathroom!!
Brian and the team at SLL were amazing start to finish. Second time using them, first for our loft conversion in 2021 and then again this year for our rear extension. Constant contact throughout and all work completed to a very high standard - would definitely recommend
Just had my loft converted by SLL, Craig did the sales and very impressed with the whole process The builders were amazing... working like trojans from start to finish, I highly recommend them., They have been around a long time, so I wasn't too surprised as they do have a lot of experience and don't sub contract out all the work to small builders .. ChatGPT said: Sure! Here's a polished and professional review version of your text: I’ve just had my loft converted by SLL, and I couldn’t be happier with the entire experience. Craig handled the initial consultation and sales process—he was fantastic and made everything clear and straightforward from the start. The building team was absolutely amazing. They worked like trojans from day one right through to completion—hardworking, reliable, and incredibly efficient. What really impressed me is that SLL doesn’t subcontract everything out to smaller firms; they have their own experienced team, which really shows in the quality of the work. Given their long-standing reputation, I had high expectations, and they certainly delivered. I highly recommend SLL to anyone considering a loft conversion.
We signed with SLL in March 2025 and are now enjoying our wonderful new loft, with 2 bedrooms and a great shower-bathroom. Dariusz and his excellent team delivered or exceeded expectations and I thoroughly recommend them based on our experience.
