The Hollow House
A courtyard cut into the slope, open only to the sky.
The house
Vestergaard put the entire house below the natural ground line and opened it to a single square courtyard. From the track above you see a meadow with a hole in it. From inside you see nothing but your own walls and the sky.
The roof is planted with the seed mix taken from the site before excavation, and it has taken.
