We used Avonvale for a 2 floor extension to our Victorian house replacing our existing dining room, utility, bathroom and a bedroom with much bigger versions. The work was complicated by the fact that we were living in the house throughout the work and that we needed the existing upstairs bathroom to be retained until the latest possible moment, building the new structure around the existing upstairs bathroom and then moving the bath, sink and loo from the existing bathroom to the new one. Rob gave one of the most detailed quotes, the negotiation was straight forward and open, and we agreed a simple contract based on the Which Trusted Trader template. Rob and his team did a great job in getting all of the work done with us still being able to live in the house, with a special mention for Phil who lead the work on site and who made sure we were involved in all of the key steps, giving us warnings of anything we needed to be aware of for the week or two ahead. Possibly the two biggest worries are expensive variations or the builder leaving the job part way through. Because of the age of the house we came across a couple of major problems where the drawings did not match the reality discovered as the existing walls and ceilings were removed. This is where Rob really starred. In both cases Rob and Phil came up with a good alternative solution, checked the acceptability of that with building control, and then gave a very fair quote for the additional work required.
