Putting a concrete basement into your brand new home is one of the best investments you can make. Basements provide inexpensive space for a variety of purposes, from a family room or entertainment center to an office or extra bedroom.

ESS undertake general and specialised basement extensions and basement construction throughout U.K. Existing basements can be extended to provide significant additional usable  space. Consequently, we can also incorporate new build basements from rear or side extension by creating additional basement price even under an existing building

Due to our basement extensions, you can have the advantage of adding upto 30% floor space to your building which adds more value to your building by incorporating a basement, relatively with just a small increase in the overall building costs costing from 10 to 20% of the original project cost.
