Four cylindrical towers raised above the ground on stilts extend from each side four-storey-high Paarman Treehouse, each offering large windows to take advantage of views in different directions.Battens of red cedar wrap the building, with larger gaps around the windows and tighter spacing to provide privacy for the residence.
