The building is mostly about the personal interaction between wealth manager and client, and the design is not so much about offices, as it is about public space. “The core focus was lobbies, meeting rooms, national and international video-conferencing, catering and (of course) the bar. “Slow Lounge” came up a couple of times during the initial briefings. Therefore we probably used as much of our expertise in hotel design as we did our experience in commercial offices,” says Silke. “Cape Town is part of the 100 Resilient Cities challenge and contributing towards climate and city resilience was an important element of the building design,” adds Möller. Green building elements which aim to reduce the environmental impact – such as energy reduction and efficiency as well as the use of natural materials – were included in the building design while sustainable practices were also used during the construction phase. For example, demolition and construction waste was diverted from landfill and where possible, recycled steel has been used. The Citadel targets the efficient use of water and limits the impact of the building’s emissions such as light pollution and ozone depletion. From an interior environmental quality perspective, comfort factors such as external views and glare control are taken into account. Ongoing assessment from the design, through the construction phase until completion has seen The Citadel being awarded a 4-Star Green Star rating. “We veered well away from the commercial obsession with glass boxes from the 1990’s and 2000’s – which is prohibitively expensive and unsustainable. Instead we opted for a crafted stone façade from Namibian granite – which offers dramatic efficiencies in heat gain and thermal efficiency. No expense was spared on state-of-the-art electrical and mechanical systems, designed to achieve drastic reductions in energy consumption. The Citadel has been rated 4-stars in the “as built” category of the Green Building Council of South Africa, meaning that the building is not only designed for sustainability – but was actually built that way. Robert Silke & Partners’ Jessica White carried out the interior design for Citadel’s internal areas and most of its sub-tenancies. Picking up from the stone facade, 28 africandesignmagazine.com
