Portside: Office Space to let in Cape Town CBD

Portside Towers — P-Grade Office Space to Rent in Cape Town.
Portside Tower is Cape Town's tallest building, standing 139 meters on the Foreshore at the corner of Buitengracht, Hans Strijdom Avenue, Bree Street, and Mechau Street. Completed in 2014, it was the first major skyscraper built in the Cape Town CBD in over 15 years, and the first tall building in South Africa to receive a 5-Star Green Star SA certification from the Green Building Council. The building delivers approximately 25,154m² of gross lettable area across its office and retail floors, with floor plates of around 2,500m² providing one of the most efficient large-format office configurations in the city. Views span Table Mountain, the Atlantic Ocean, the harbour, and the Cape Town skyline from virtually every level. With over 1,400 parking bays, direct highway access, and a ground-floor retail and restaurant offering, Portside is a self-contained business address at the centre of Cape Town's financial district.

Portside Tower offers office space from partial floors to full-floor tenancies of approximately 2,500m² — one of the largest single-floor configurations in the Cape Town CBD. The floor plates are designed for efficient open-plan layouts, with the flexibility to incorporate collaborative areas, private offices, boardrooms, and executive suites within a single level. This means most businesses can house their full operation on one floor rather than splitting teams across multiple levels.

The let-able office floors occupy levels 9 to 18. The azure double-glazed façade runs the full height of the building, providing high levels of natural light across all floors while reducing reliance on artificial lighting. On clear days, views from upper floors take in Table Mountain, the Atlantic Ocean, the harbour, and the full Cape Town city bowl

5-Star Green Star — South Africa's Greenest Tall Building
Portside Tower was the first tall building in South Africa to receive a 5-Star Green Star SA Design rating from the Green Building Council, and subsequently earned the 5-Star Certified rating. For businesses with ESG commitments, carbon reporting obligations, or sustainability targets, occupying a 5-Star Green Star certified building directly supports those requirements.

Parking at Portside Tower
Portside Tower has over 1,400 parking bays across three basement levels and seven structured podium levels, among the largest on-site parking provisions of any single building in the Cape Town CBD. The parking structure supports staff, clients, and visiting vehicles without dependency on external public parking.

Location — Buitengracht Street, Cape Town Foreshore
Portside Tower straddles a full city block on the Foreshore, bounded by Buitengracht Street, Hans Strijdom Avenue, Bree Street, and Mechau Street. This position sits at the boundary between the Foreshore financial district and the upper CBD, giving tenants access to both precincts without being embedded in either.

Highway Access
The N1 and N2 highway on-ramps connect directly to Buitengracht Street and Hans Strijdom Avenue, placing Portside within minutes of both the northern and southern suburbs by car. Cape Town International Airport is approximately 20 minutes in off-peak traffic. Staff commuting from Stellenbosch, Somerset West, or the Atlantic Seaboard can reach the building by car without navigating the congested lower CBD grid.

Public Transport
Cape Town Station, the main rail and MyCiTi interchange for the metro, is within easy walking distance. Multiple MyCiTi bus routes and minibus taxi routes serve Buitengracht Street and the surrounding Foreshore streets, giving the building broad accessibility for staff arriving from across the metro.

Surrounding Business District
Portside sits within the Foreshore's emerging financial district, surrounded by the offices of major banks, insurers, law firms, and professional services businesses. The CTICC, multiple five-star hotels, and the V&A Waterfront are all within a short drive. Ground-floor cafes and restaurants within the building itself cater to daily working needs without requiring tenants to leave the block.
