There are many factors that affect the cost of constructing a new basement to your home. The cost of basement construction is decided by the ground conditions, the ease of access during the build in terms of spoil removal, along with the finished specification. Other factors which affect the cost of construction is the finished required head height and layout. Bathrooms can easily be fitted into your new basement but require sewage pumping stations to remove the grey waste. Also, there is the matter of what permits are required to undertake the construction works and these may include bay suspensions, skip licence, hoarding licence, conveyor belt licence and a material permit. In areas where there are poor ground conditions or a high water table, this can add to the costs as well.
