Clients benefit from a streamlined process, from initial survey to final decoration, ensuring minimal disruption and guaranteed timelines.

Dormer loft conversions expand headroom and floor space, ideal for creating bright, airy bedrooms or workspaces. We handle all aspects, from planning permission to structural work, using premium materials for durability.

My wife and I had our loft conversion done by Ash Island back in January and February and couldn't be happier with the end result. From the very start, with our first meeting with Matt to discuss our plans, all the way through to completion, they were fantastic throughout. The construction team were always on time each day, kept us updated with the schedule, made sure the property was kept as clean as possible, always found solutions to tricky problems, resolved the few issues there were straight away and completed the work in a quick timeframe and to a brilliant standard. The neighbours also commented

We are really happy with our loft conversion (two bedrooms and one bathroom) and Matt and the team made it a really smooth and easy process from start to finish. The level of detail and breakdown to their quote was refreshingly transparent and meant there were no unexpected surprises at the end. Karel managed our project day to day and he was brilliant. A real asset to the business - very efficient and on top of everything. Communication was great throughout. We were impressed with the speed of the build and the project ran seamlessly. We were happy with the quality of the work, and all the trades

A big thank you to Matt and his team for completing our loft conversion well within the time period they quoted, professionally and smoothly.
Matt is a great chap to speak too and he will answer any queries promptly, also I have to give a big thumbs up to our Project manager Timmy and also Robert who both worked on our build from start to finish, both were pleasant and professional to have on-site during the build, in fact, all the team that worked on our build were great along with Michelle and Chris in the office. I would highly recommend Ash Island to anyone considering a loft conversion

We wouldn't hesitate to recommend Ash Island. They converted what we thought was a small unusable space into a roomy, light double bedroom and bathroom loft conversion which has transformed our house and looks as though it's always been there. They took care of the whole process from design through planning to completion. They clearly are total experts and we received a much better service from them than anyone else we looked at in terms of design, cost and timescales. They were friendly, efficient and trustworthy throughout and excellent value for money. Thank you to everyone at Ash Island!

We found the team at Ash Island Lofts really affable and easy to do business with. We appreciated how transparent their quote was. There were no hidden charges and any additional work needed during the build was always discussed and agreed with us before pressing ahead. We also liked the fact we were able to visit a previous job close to us to see the space we'd be able to get before commissioning the build. We had a two room dormer loft conversion (which included lowering ceilings) completed on schedule in six weeks as promised and are thrilled with the result. We were kept up to date through
