This total house remodel included adding a third floor master suite and family room to this two-story, single-family residence located on Potrero Hill. The third floor addition steps back, allowing for generous decks and is articulated as two interlocking cubic forms. A luxurious bath clad in Carrara slabs and mosaic offers a spa retreat for the owners. A slot window set between the master vanities further emphasizes the dramatic view. The main floor ceilings were raised to ten feet with all new finishes throughout.
