The 1.5m deep reinforced & waterproofed pit was prepared for the 5.3 x 3.8m pool to be craned into before the walls and roof of the extension could be built around it.

Drainage installed to manage surface water and an emergency bilge pump will kick in and empty the tanked pit in the event of flood or malfunction.
