Teepee

Made from reclaimed wood by Irene’s furniture-designer father, the teepee’s frame doesn’t obstruct the lines of the clear space, but its curtain can be rolled down for privacy when needed. It is used as a den for reading or meditation, and as a spare room for guests.

Plants

Building the heating system into the clay walls was one of Irene’s ideas for energy efficiency – and it also creates a good climate for plants. “Greenery really makes a home,” she says.

Mixing pale materials with untreated wood creates a naturally calming effect
