Malan Vorster selected only materials that would reflect the passage of time by weathering naturally. Columns, arms and rings are made from Corten steel plate, with the building envelope consisting of timber floor beams, western red cedar and glazing. Hand turned brass components accentuate the connection points between steel and timber. With time, the untreated materials will blend in beautifully with their environment, making the cabin a tree house in the truest sense of the word.
