Sometimes the most fruitful journeys are the ones that begin without a fixed destination. Consider the finely tailored modernist house that the Los Angeles architecture firm Woods + Dangaran designed for a real estate developer in the city’s Mar Vista neighborhood. Uniquely responsive to the exigencies of its site at the crest of a sloping hillside, the striking residence should finally put to rest the old canard that modernism is somehow inimical to warmth and comfort.
