Remodeled 1 bed plus den with 2 full baths on the 6th floor of Tidemark, the Key Colony I tower on the ocean side of Key Biscayne. 1,059 SF with ocean views and an open balcony facing east, so you get the sunrise over the water every morning. The kitchen was rebuilt around a stone island, with custom millwork and designer lighting carried through the whole unit.
