The Hollow House cut into the forest slope

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.

Shown by appointment only, accompanied.
