Thanksto large sliding glass doors, inside and outside becomeone, with a continuous raw concrete ceiling and identicalwindow sizes.

On the ground floor of this generously open plannedunpretentious simplicity and elegance, there are twolarge children’s rooms in an area of 280 square metres, abathroom and a granny flat.
