The pool is twelve metres by four, which is long enough to actually swim rather than just cool off. Depth runs from 1.2 to 1.8 metres, so it is usable by children without a separate shallow section.

It is heated by the same air-source system that serves the house, and an automatic slatted cover cuts evaporation overnight — the single biggest cost in running a heated pool.

The deck

The south deck is sheltered on two sides, which extends the usable season by roughly six weeks at each end of the year.

Plant and upkeep

Filtration and dosing are automated and housed in the garage plant room, away from the house.
