Two separate condominiums were completely reconfigured to create a single new residence. Thickened walls that hide plumbing risers delineate the public living spaces from the more intimate master and guest suites. A “service core” clad in Brazilian cherry provides a transition from the entry to the living room. Combining what were bedrooms in separate units, the new living room occupies the full width of the building’s east bay enabling 180 degree city views. Details of blackened steel provide a tensile contrast to the solidity of the wood and plaster walls.
