Office parks reimagined

Office parks reimagined: When sustainability meets market leadership

By Samantha Lambert, General Manager, Redefine Properties

In an era of unprecedented environmental and operational challenges, South Africa’s office parks stand at a critical juncture. Energy insecurity, water scarcity, and ageing municipal infrastructure are no longer distant concerns but immediate challenges that demand innovative solutions. Yet, within these challenges lies an opportunity to reimagine office parks as beacons of sustainability and operational resilience.

The business imperative for sustainable office parks

Sustainable office parks are no longer just an environmental consideration; they are a business imperative. Unreliable municipal power supply and recurring water shortages directly impact operational continuity and tenant satisfaction. Simultaneously, tenants and investors increasingly demand spaces that combine operational resilience with environmental responsibility. This convergence of operational necessity and stakeholder expectations is reshaping how we approach office park development and management.

Black River Office Park in Cape Town’s Observatory district exemplifies this transformation. The park’s evolution has been accelerated by significant node activation, including Amazon’s new head office development across the way. This strategic location, with its superior road infrastructure connecting to both northern and southern suburbs, has catalysed the area’s development into what we envision as an emerging Century City-calibre node.

Infrastructure that powers performance

Leading sustainable office parks are distinguished by infrastructure investments that address both environmental impact and operational resilience:

  • Renewable energy systems: Black River’s solar fleet, with an installed capacity of 1,496 kWp supported by 5,715 panels, significantly reduces grid dependence while ensuring consistent power supply.
  • Backup power solutions: A comprehensive backup generator system, coupled with a centralised power plant, ensures business continuity during grid interruptions – a critical feature that’s no longer optional but essential for tenant operations.
  • Water security measures: Strategic use of borehole water for refuse yards and irrigation supports water-wise landscaping, reducing municipal water dependence while maintaining attractive green spaces.

These investments deliver measurable returns through reduced operating costs and enhanced tenant satisfaction. The park’s near-full occupancy demonstrates the strong market demand for sustainable, resilient office space.

The multi-tenant advantage: How diversity drives growth

Sustainability extends beyond utility management to encompass how spaces support diverse business needs. Black River Office Park comprises 14 distinct buildings, each with its own identity, enabling a unique ecosystem where corporate offices and business process outsourcing (BPO) operations successfully coexist. As we’ve discovered, sustainable office parks must be flexible enough to accommodate varying density requirements while maintaining premium-grade standards.

The park’s design thoughtfully incorporates energy-efficient building systems alongside carefully planned green spaces that enhance both environmental performance and user well-being. Supporting amenities promote tenant productivity and satisfaction, while flexible spaces readily adapt to changing business needs.

This approach has attracted a diverse tenant mix, including boutique gyms, award-winning salons, medical practices, and varied food offerings. As a result, it has created a vibrant, community-centric environment that supports approximately 2,000 employees, a number set to double with recent expansions.

Collaboration: The key to sustainable success is collaboration

Achieving meaningful sustainability requires close collaboration among REITs, tenants and vendors. At Black River, this collaborative approach begins with our tenants, working closely with them to optimise space utilisation and resource efficiency. We engage suppliers in sustainable procurement practices while maintaining strong partnerships with the City of Cape Town and CapeBPO to align with regional development goals. Our Red Thread initiative exemplifies this collaborative spirit, repurposing materials from gutted buildings to benefit the community and demonstrate our commitment to circular economy principles.

Smart design, smarter returns

Modern technology plays a crucial role in maximising sustainable infrastructure performance. At Black River, we’re investing in smart building systems for resource optimisation, complemented by advanced monitoring tools for energy and water consumption. Our commitment to continuous assessment of environmental performance drives strategic upgrades that maintain our premium-grade status.

The planned redevelopment of Gate House, which anchors the entry point to Black River Park, illustrates our commitment to ongoing evolution. This project will enhance the building’s exterior while maintaining its distinct character, demonstrating how sustainable design can complement heritage features.

Market leadership through environmental excellence

As South Africa continues to face environmental and infrastructure challenges, sustainable office parks will play an increasingly vital role in our business landscape. The success of Black River Office Park demonstrates that sustainability isn’t just about environmental responsibility; it’s about creating resilient, future-ready spaces that deliver lasting value for all stakeholders.

Property owners and managers must take a long-term view, balancing immediate operational needs with future sustainability requirements. This means investing in robust infrastructure, fostering collaborative ecosystems, and maintaining unwavering commitment to continuous improvement.

The future belongs to office parks that can adapt, evolve and thrive in the face of change. Embracing sustainable practices today not only protects our environment but also ensures the long-term viability of our assets. At the same time, it creates spaces where businesses can flourish for generations to come.

Olympus Sandton achieves stratospheric sales success

The landmark Olympus Sandton residential and retail development has achieved a phenomenal R940 million in sales just days after its luxury apartments were launched for public purchase on 27 February 2025, with 295 apartments sold by the close of the public sales launch weekend.

Olympus Sandton is being developed by Growthpoint Properties (JSE: GRT), South Africa’s leading real estate investment trust (REIT), in partnership with Tricolt, a premier developer specialising in high-end residential projects. It is the latest development in Sandton Summit, where Growthpoint is shaping its vision to create South Africa’s premier walkable mixed-use precinct. At the high-profile junction of Sandton/Katherine Drive and Rivonia Road, Sandton Summit is anchored by Discovery’s iconic head office building (co-owned by Growthpoint 55% and Zenprop 45%). Adjacent to this landmark, along Rivonia Road, the Olympus Sandton high-rise residential development will elevate fine living in vibrant Sandton, setting a new benchmark with 512 state-of-the-art apartments across its two towers.

The development’s first 24-storey residential tower, The Athena, is nearly sold out with 227 of its 288 apartments already secured by eager buyers.

Tim Kloeck, Chairman of Tricolt reports, “Olympus Sandton sales are exceeding all expectations. In response to the overwhelming demand, we are pleased to announce the immediate release of apartments for sale in the second tower, The Apollo. Tricolt brings its expertise in world-class residential living to this landmark project.”

The first 68 of The Apollo’s 224 apartments were snapped up swiftly on release.

Neil Schloss, Head of Asset Management: South Africa at Growthpoint Properties, adds, “The exceptional sales momentum has accelerated the Olympus Sandton development timeline, and we can confirm that construction of both towers should commence in the latter part of 2025 and early 2026. The development’s sales success exemplifies Growthpoint’s strategic approach to unlocking maximum value from prime real estate assets through strategic, market-aligned development and partnerships.”

Kent Gush from Kent Gush Properties states, “I have been selling property for 40 years in Sandton and Olympus has been the most incredible success story of my career.”

Olympus Sandton offers a variety of premium residences, with prices ranging from R1.49 million to R7.2 million for studios and one- and two-bedroom apartments. Penthouses are available from R14 million to R45 million.

The sales team notes that buyers report Olympus Sandton’s most compelling features are its prime position in vibrant Sandton Summit, offering effortless connectivity, premier amenities and a dynamic neighbourhood.

Growthpoint and Serra® set a new benchmark 6-Star Green rating

Growthpoint and Serra® set a new benchmark for logistics and industrial properties with 6-Star Green rating

In an environmentally innovative achievement, the Serra® facility, owned by Growthpoint Properties (JSE: GRT), has become South Africa’s first industrial property to earn a prestigious 6-Star Green Star Existing Building Performance (EBP) rating from the Green Building Council South Africa (GBCSA), setting a new benchmark for logistics and industrial properties.

Located in Meadowbrook, Germiston, the 7,400sqm light manufacturing facility has consistently been an example of a strong commitment to leading green building standards. In 2020, it was awarded a 5-Star Green Star EBP rating, marking the first time an industrial building in Gauteng had achieved this certification.

The new 6-star rating recognises an ongoing sustainability journey. Underpinning the achievement are Growthpoint’s 15 years of recognised green building leadership and Serra®’s 40 years of experience in the commercial washroom industry, resulting in a deep focus on water efficiency and conservation at the property. This powerful partnership also earned the building the 2024 GBCSA Leadership Awards for theHighest Rated Building (EBP), with accredited professional Danika Taylor of Imbue Sustainability also playing a key role in achieving this milestone certification.

The building boasts several cutting-edge features that contribute to its impressive green credentials. The entire facility is 100% off the grid. It features solar PV energy generation and waste management, including recycling.

Yet it shines brightest in its positive impact on water resilience – the heart of sustainability. The property features substantial rainwater harvesting, including a petrol/oil separation system for water recycling, a water purification plant, and an underground water reservoir about the size of an Olympic swimming pool. This is particularly significant given the current water scarcity concerns in South Africa, especially the diminishing water security in the Gauteng region.

The alignment between Growthpoint and Serra® in their environmental commitments makes this property a standout example of cooperation between a property owner and occupier, especially when both are leaders in environmentally sustainable practices in their respective sectors.

Growthpoint’s goal is to be carbon neutral by 2050. Its progress includes 123 current green building certifications and securing access to a rapidly growing reliable mix of renewable energy sources – electricity from water, on-site and remote solar, and wind – for tenants to access through its e-co2 benefit scheme, being the first of its kind in South Africa. Thanks to a PPA with Etana Energy, Growthpoint will begin wheeling 195 GWh/y of renewable energy to select buildings starting from July 2025, which represents 32% of its total electricity consumption and demonstrates its commitment to innovative, scalable energy management.

These and other sustainable business practices not only move Growthpoint closer to its ESG (Environmental, Social, and Governance) targets but also help tenant businesses towards their own ESG goals.

As a proudly South African family-run business with a strong passion for ESG principles, Serra® is wholly invested in sustainable green practices and has voluntarily pursued rigorous sustainability certifications. This goes well beyond its manufacturing and showroom facility. Serra® has made substantial investments in developing sustainable products and practices. For instance, it supplies floor covering and mats from recycled fishing lines recovered from the ocean. It is aiming for Net Zero emissions.

Paul Thomaz, CEO of the Serra® Group (Pty) Ltd, comments, “Our business is dedicated to creating a positive impact on the environment and communities we serve. Working with Growthpoint to achieve the 6 Star Green Star reinforces our long-term vision of minimising harm and promoting sustainable practices throughout our operations and product offerings.”

The Serra® building’s 6 Star Green Star EB rating sets a new benchmark for logistics and industrial properties in South Africa. It continues Growthpoint’s pioneering approach to green logistics and industrial buildings in South Africa. The company jointly developed the GBCSA’s certification tool for industrial facilities in a progressive move that enabled more building types to be certified green. It was also awarded South Africa’s first-ever Green Star SA rating for industrial property, for Greenfield Industrial Estate in Cape Town.

Errol Taylor, Growthpoint’s Head of Asset Management: Logistics & Industrial Property, says, “Growthpoint is committed to providing relevant spaces that support occupants while addressing key global and local efforts in response to environmental concerns. We are incredibly proud of this achievement and the strong partnership with Serra® that has made it possible.”

The environmental commitment of both businesses is being put into action in other ways too.

As a leading hygiene services provider and washroom accessory manufacturer, Serra®’s commitment to environmental responsibility extends to its service agreements, and the company currently services around 90 of Growthpoint’s Johannesburg buildings. This not only benefits Growthpoint as the owner but also enhances the experience of the tenants.

The 6-Star Green Star rating for the Serra® building underscores the growing importance of certified green credentials. As businesses increasingly prioritise ESG considerations, buildings that can demonstrate exceptional operational performance are increasingly attractive to tenants and investors.

For Growthpoint, the Serra® building’s new rating is a testament to the value and impact of its green initiatives. The company continues to explore and collaborate on opportunities to enhance the sustainability of its portfolio, creating properties that benefit both the environment and those who occupy them.

For Serra®, its manufacturing and showroom facilities serve as a living inspiration for environmental sustainability, and it welcomes designers, facility managers, property developers and built environment professionals to visit the property to encourage greater green building excellence.
