The Rubik is a 27-storey mixed-use tower designed for Abland Property Developers. The developers wanted a viable yet unique design for a modern mixed-use building on an 821m² site that straddles the historical inner-city district and the more recently developed city blocks north of Riebeek Street in Cape Town’s CBD. The design needed to address the challenge of its location in a Heritage Overlay Zone and required approval from heritage authorities. The result is a distinctive form that rises to 91 meters. While exceeding initial height restrictions, the resulting approval led to a building that enhances the city skyline with its dynamic sculptural elegance.

Retail spaces activate the streetscape from ground to first floor and the parking podium rises ten floors above. The upper levels, from floors 11 to 26, are divided into three stacked,orthogonal twisting cubes rotated around a central axis. These levels contain commercial offices and residential apartments, including one- and two-bedroom units, duplex and triplex penthouses. The fragmentation creates visual interest and captures varied reflections of the surrounding cityscape. Small recessed terraces punctuate the facade, adding to the building’s aesthetic.
‍

The façade design is thoughtful and contextual. The parking podium’s exterior references the scale and rhythm of nearby heritage buildings, using a combination of pre-cast concrete, extruded aluminium, and glazed panels. The office and residential levels feature flush glazing co structural elements and incorporates discreet balconies.
‍

Despite the tight site constraints, the internal layout maximises efficiency. The centralised lift core and scissor stair accommodate parking circulation below while providing flexibility for office and residential layouts above. Terraces to the residential units are stepped back, providing protection from the weather. A common roof terrace with a pool and indigenous planting crowns the building.
‍

The Rubik incorporates several sustainable features including high-performance glazing, energy-efficient systems and environmentally-friendly materials. Its mixed-use nature and central location promote urban density and walkability, aligning with sustainable urban development principles. Overall, The Rubik stands as a significant contemporary addition to Cape Town’s skyline, balancing modern design with sensitivity to its historic context while promoting a vibrant, mixed-use urban environment.
