The planning stage was painless and the build was very professional.I believe the main build was completed in 5-6 weeks. Chris Spencer was efficient at managing the team and everything ran like clockwork, whilst communication was prompt and clear throughout and all second fixes were completed tidily. Throughout the project, a high level of attention to detail was maintained. I would strongly recommend Crown to prospective clients in the future, and especially Chris and his team.Andy BoneWe completed our loft conversion with Crown last year and we’d definitely recommend them!From when we first met Tom, through to all the office team and contractors, we really appreciated how professional, friendly, honest and trustworthy they were. We love our new space they created and would definitely use them again and recommend them to friends and family.Andy DaviesAmazing! We were so happy with the service and quality of finish that was created with our loft conversion.Chris was fantastic and made the whole process easy. The tradesmen that were provided were brilliant – we couldn’t recommend Crown more highly.Lisa MarieI can’t recommend Crown Developments enough. We have a fantastic new loft bedroom with library and bathroom; the finish is fantastic.Our builders Leigh and Tom were an absolute pleasure to have on site – trustworthy and reliable. They were also really responsive when we needed to communicate out of hours and I knew when they were going to be here and what they were planning to do each day.Gemma Scott-SmithWe’ve chosen Crown Development Services from a handful of companies and we’re really glad we did.From the moment the project started it was on schedule, and it’s now been finished to a high standard and met our expectations. We have minimum experience with any sort of construction work, so it was great that we could fully lean on the whole team (Tom, Lina and especially the main project lead Leigh) with all our questions, ideas and concerns.Honza KeprtaTom and the team have been professional and responsive throughout our loft conversion journey.From the first Zoom meeting with Tom we were sold on the family run business feeling, time taken to listen to what we wanted and professional advice. Nothing was too much trouble and we were kept up to date with each stage of the process. The build even finished early which was a big bonus. I would highly recommend this company to anyone wanting a loft conversion.Jenny CreaseyThe team at Crown were great, from Tom coming out and giving us our quote to our builder John; even the scaffolders they used were great.We are so pleased with the job they have done. The loft conversion is brilliant, our builder, John was amazing – his attention to detail was great. He really cared about his work and kept us up to date each step of the way. Would definitely recommend Crown Developments if you are looking for a loft conversion.Adam FowlerWe have recently had our loft completed, and are so impressed with the work and space it has created.From start to finish Chris and Calum were friendly helpful and answered any questions we had. We were told 12 weeks, but it was complete in 6, Chris works so fast – great guy. Behind the scenes Lina is great at getting things to site to avoid hold ups. Thank you Crown and in particular Chris and Calum.Lara ShepherdWe’ve just completed our loft conversion this summer.We now have a new playroom and study. The girls have their new playroom!
