Taschen House
The 1960 octagonal Chemosphere House & the proposed extension by OMA is located on the San Fernando Valley side of the Hollywood Hills. The extension would provide a guesthouse and a sundeck with swimming pool. The (new) guest house is connected to the (old) Chemosphere House by a hillivator: providing a rollercoaster-like ride through the sloped area to the extension.
