We had a double loft conversion by Kingsmead. Our David Wilson Homes property had two separate lofts, one much smaller than the other and the end result is impressive. We have created two bedrooms, one with an en-suite. The price was competitive and ££ extra's (changes jointly agreed) were fair and reasonable. Overall, the build went well and Kingsmead has created a usable and valuable space using some excellent key trades although it wasn't without challenges. All were friendly and communicate reasonably well together - plasterers (who were fantastic) talk with the tiler (who was also fantastic) and the electrician (just great) finished off with a very competent carpenter. The messy bit (loft steels, roof structure, stairs) went well albeit interrupted by Xmas and an over-optimistic schedule. Plumbing was terrible which led to a number of awkward conversations. The snagging was carried out by Darren & Nick and they were just excellent, challenging trade decisions made previously which we weren't happy with and putting them right. Adam is a good guy who has a lot of concurrent projects so co-ordination relies on the trades talking to each other and updating Adam which worked most (but not all) of the time. As customers we were on site every day since my partner works from home. I would advise that you take an active role in the 'oversight' without getting in the way too much and record areas of concern or reminders whilst the trade is on-site. You will have to intervene occasionally to assist with co-ordination and don't be afraid to challenge. I would recommend Kingsmead.
