Very interesting. I love the brutalist look of the penthouse and the down to earth attitude of Pieter. I live on the other side of the river :-) Would love to once visit this place. Cheers, Luc.
If that is an apartment on top of a building, he must have had the load-bearing structural columns beefed up to take all the weights from soil that he needed for all the trees and plants that are in the garden. I'd love to see the place in person.
