providing new commercial and retail spaces, a 150-key Canopy by Hilton hotel, and secure pedestrian routes linking Kloof Street to Cape Town’s CBD. The client brief for Longkloof’s catalyst project, 32 on Kloof, was to establish additional premium rentable space by adding two floors to the existing building, maximising the floorplates and reinventing the windowless basement. Ultimately, the client’s vision was for 32 on Kloof to serve as the attractive ‘front face’ of the Longkloof precinct concealed from Kloof Street. dhk’s response was to respect the buildings’ heritage and intentionally contrast its existing order and rhythm with a new contemporary addition. This concept allows for an honest dialogue between heritage and contemporary elements, forming a hybrid of architecture that politely enhances the building’s street presence. To increase the building height and provide additional commercial space, the existing hipped red-tiled roof (originally added in the 1990s) was removed to allow for a two-storey orthogonal addition atop the heritage masonry building. Not only does the glazed façade showcase the property’s enviable Table Mountain and City Bowl views, but the two distinct levels provide a clear distinction between old and new – referencing, not replicating, the building’s heritage. Deep expressed aluminium-clad fins articulate the façade, contrasting the historic building’s order and rhythm while acting as a ‘stitching device’ integrating the heritage detail with the contemporary portion. To ensure a single articulated composition of contrast, building setbacks permitted by Heritage Western Cape were contested. Overall, the minimalist design refrains from competing with nor detracting from the building’s heritage, ensuring that the total building mass and scale are sympathetic to its surroundings. Occupied by Workshop17, a provider of coworking spaces, the building offers 30 private offices, nine meeting rooms, three boardrooms, a seminar room, event space and bar, six lounges and libraries, and a courtyard and café. Striking yet respectful, the contemporary addition modernises Kloof Street’s streetscape and serves as an indicator to the upgrades occurring behind the building. The new sunken courtyard is another notable element of the design. Constructed at the rear of the building, the courtyard was reinstated by demolishing the two-storey 1990s annexe building and lowering the existing courtyard to align with the basement level. The existing retaining walls were broken out to create new glazed frontage facing the courtyard with external staircases on the northern and southern ends connecting the courtyard to Kloof Street and the remainder of Longkloof. A café occupies the courtyard and basement, engaging the local community and forming an exciting new hub of activity within the area. 32 on Kloof 35
