WHO'S WHO IN CONCRETE
16 on Bree Street Renowned as Cape Town’s tallest residential tower, a phenomenal 36-storey building is located on the everpopular Bree Street. Strategically situated in the CBD, it is within walking distance of attractions such as the V&A Waterfront, Cape Quarter and Green Point, with spectacular views of Table Mountain, the Atlantic Ocean and the cityscape itself.
on Bree Street offers a broad range of accommodation, from R1.9 million studio apartments through to premium penthouses valued at R13.9 million.
