Delaying decisions is one of the worst mistakes in a rénovation maison (house renovation) project. If you want the process to work well, make sure that you make all the big and small decisions before the work begins. If you are not too experienced with such things, a professional builder will always be able to take you through all the major considerations. There are a lot of situations that may arise, so each of them must be considered upfront. Delaying small decisions can lead to a lot of problems, such as mismatching bathroom furniture and plumbing.
