The Holstein house is an exceptional Berkeley Hills residence designed by John Hans Ostwald. It is sited to take full advantage of its peninsular lot at a sharp turn on Buena Vista. Ostwald did not use the butterfly roof frequently, but here he incorporates it with great aplomb to open the living room to grand Westerly views. It is yet another example of Ostwald’s immense creativity and willingness to experiment with a variety of forms.
