Above the stone layer is located the terraces: an extension of the social area -kitchen, dining room and living room - covered with a wood roof that protects form sun radiation.

Covered terraces and automatic sun roofs above the morning terrace and the patio make it possible to enjoy the sun's heat whatever the season.

Walls of glass throughout the house face the countryside, while decks and sunrooms double as heat sinks and sources of passive solar energy.
