breeze blocks carved thermolight blocks

A friend was building a sauna – I was commissioned to build the
plunge pool in it. The challenge was to make use of the limited &
unusually shaped space available (the sauna was in the shape of
a nautilus shell), & consider practicalities such as access &
waterproofing as well as aesthetics. It’s built from breeze blocks,
carved thermolight blocks & then rendered.
