Every project that we take on is different, in both its complexity and size and therefore it is very difficult to give an exact timescale. Prior to any project being carried out we will issue a detailed programme. On average a basement conversion would take between 26 and 35 weeks, and a rear extension up to 26 weeks.
There are no reasons why a basement should now be a damp room underneath the rest of the house as long as the waterproofing has been well considered and well designed. In our basement conversions, specialists install a cavity membrane system which works on the principle of allowing water to continue to penetrate the structure but control it in an air gap and then divert it to a suitable drainage point. The advantage of this is that there are not the potential week spots, which can lead to leaks, stained walls and an odor associated with the cementitious tanking system. When we design a basement we will incorporate as large a lightwell at the front and ideally at the rear as possible. This will ensure that natural light floods the building. By the clever use of glass balustrades and skylights we can add more light.
