We have a base in South London but we can quite easily work anywhere in the Greater London area. We've worked all over and we'll normally have a loft converted not too far from where you live, we'll aim to show you a local project so you can check out work

Probably the most common loft conversions happen on these types of houses. Check the options here and you will find something similar.

Some end-of-terrace conversions are the same as if a house were mid-terrace, some are gable ended and some have the sloping hip end.

This period of property is one of the most commonly worked on through out year, and we have many examples for you to view.

If you live in a conservation area, the council may not allow you to have a rear dormer, but they will let you have a mansard or a combination of Velux roof windows and small dormers.


  • We were absolutely thrilled with the work that South London Lofts did for us last year. They were incredibly professional and a delight to deal with. The entire team worked very hard to get the work done and we’re really pleased with the result. We had a couple of issues after the work was finished and I was very impressed at the speed and efficiency with which the project manager and roofers returned, dealt with the problem and made the necessary repairs. The extension is so well done I can’t actually remember what the house used to look like before…

  • We chose to go with South London Lofts due to their credibility and reputation that they had in and around my surrounding area. The work was of high standard, was completed in budget (no hidden surprises), and on time. The after service care has been impeccable as well. I would highly recommend using SLL.

  • Just to say we were very happy with the conversion. From start to finish. It was very well organised and the team working on the loft were thoroughly considerate and professional throughout.

    We would not hesitate to recommend your company to others considering a conversion.
