CALCULATING BASEMENT COSTS: In very broad terms, the following are the typical range of costs for a completed basement project of circa 100 Sqr M: • Professional Services These fees typically come in at £60,000 to £120,000 +VAT depending on the extent of services engaged and scale of project. • Basement ‘shell and core’ construction (including insurances and guarantees). Costs are typically £2,700 to £3,700 +VAT per Sqr M. This generally comprises the excavation and creation of your watertight concrete box. It includes the perimeter walls, superstructure steelwork and underpinning, concrete floor slab, roof slab, ground and foul water drainage and architectural glazing. • Basement fit-out Costs are typically £1,000 to £4,000 +VAT per Sqr M. This covers labour, fixtures, fittings, equipment and finishes for all the internal elements of your new basement. These costs are hugely variable according to the selections that you make. For example, timber floors can range between £50psm to £400psm. It is also driven by what you are going to use the space. For example, cinema rooms and swimming pools are far more expensive than bedrooms and playrooms.  SUMMARY In summary, the three biggest factors that dictate the cost of your new basement are: • The size/volume of your new space. • The extent of expertise required from various Professional Services firms. • The quality level of the fit-out.
