basement conversions - basement sitting room and stairsBasement conversions are an increasingly popular way to create extra space for homeowners in London. Absolute Building & Construction Ltd. are one of the London’s leading basement conversion specialists and we can offer a complete design and build package for your basement conversion project.

Our experience allows us to accurately cost the excavation and structural elements of the work with very little variation. Although the exact makeup of your soil and water table under your house will need to be taken into account these are similar across large areas of London. We can calculate the cost of your conversion based on the size of the space and a small number of other straightforward parameters.

Part of the cost of your basement conversion will depend on exactly what you want to do with the finished space. Basement conversions in wealthier parts of London can include full scale swimming pools, gyms, garages, cinemas and even bowling alleys. More standard uses for the extra space created by a basement conversion are play areas for children, lounges and kitchens. Whatever the use you intend to put your basement to we will ensure the space is dry, well ventilated and has ample natural light.
One of the biggest considerations when planning a basement conversion project is how it will impact on your day to day family life. We will work with you to plan out when and how the work will be done to minimize disruption to you, and to your neighbours. This will include detailed planning of how we are going to do to the excavations and structural work.
