BASEMENT CONVERSIONS

If you already have a cellar or basement, then converting it into a new living area is well worth considering, however, if you don’t have a pre-existing cellar then creating one can cost the highest amount per square foot of space compared to any other type of extension and will need to be done by experienced and expert professionals.

By having the project assessed first, you can find out how much work is entailed in converting it to your proposed use – especially important is waterproofing (tanking or drainage) and an expert will be able to advise you what is needed (do you know how high your local water table is?) in order to ensure your basement conversion is free from water penetration & damp problems. Not only that, you may not have enough headroom in your existing basement and could have to lower the floor level (you need about 8 feet or about 2.4 metres floor to ceiling as a rough guide).

You can then agree a design, sort out any “party wall’ issues, find out what planning permissions & building regulations that need to be met and get a quotation for the cost of the proposed work.
