Liberty Holdings and Pareto Limited's reinvention of the iconic Atrium of 5th (previously known as the Sandton Twin Towers office complex) is nearing completion.

5 Atrium

The premier office space on 5th Street in Sandton forms part of the renowned Sandton City complex and is a prime asset in its owner's property portfolios.

A key aspect of the building's revival is the creation of an 11-storey high glazed atrium, maximising the splendid views up Maude Street.

Speaking on behalf of the property owners, Amelia Beattie, Chief Investment Officer for STANLIB Direct Property Investments (who act as asset managers for Liberty Group's 75% ownership investment in the centre) says,'The building's glass façade will make it one the most eye catching buildings in Sandton.

The suspended glass atrium,is a first in South Africa, with a light post tensioned steel work structure which isn't visible through the glass sheeting'.

The creation of such a prestigious address has attracted the attention of several prominent tenants. 'A number of international banks have already secured space in the development and the SA Gold Coin Exchange (Scoin) will be leasing an entire floor.

Several proposals for the remaining space are currently under review,' Beattie says. Sustainability has been an important driver in the refurbishment, with the project aiming to achieve a 4-Star Green Star SA Office Design and As-Built rating.

Graham Kusano, Divisional Director: Property Development at Liberty Properties (developers and managers of the undertaking on behalf of the property owners) comments, 'The rejuvenation of this 32 year old building presented the ideal opportunity to incorporate numerous environmentally sustainable principles into the design.

Perhaps the most noteworthy is that the entire building structure has been re-used. This means there has been no need for any demolition or construction of an energy intensive new building structure'.

It is a factor that posed a number of challenges for the developers. 'Access to the building has always been a challenge and no tower cranes were possible due to the new façade.

Also the building has been occupied by tenants throughout the refurbishment,' says Kusano. 'To ensure seamless occupancy on their behalf, we completed the first to 4th level floors and then relocated tenants to this completed area.'

The developers have extended the floor plate and changed the façade of the building, whilst continuing to provide unbroken service to existing tenants. Kusano says, 'We achieved this by installing a temporary water tight perimeter to the new façade, as well as the erection of a temporary plant while the existing one was being replaced.

Strict programming has also ensured tenants and visitors to Sandton City and the adjacent hotels have not been adversely affected.

With the vision to create a truly green building, the glass atrium with its new high performance double glazed and insulated façade, will ensure optimal access to views and daylight whilst minimising heat losses through the building envelope.

Kusano says the building's air conditioning system has also undergone a major upgrade to maximise energy consumption and ensure thermally comfortable indoor conditions.

'We were determined to reduce the building's carbon footprint and to this end, we have also accommodated an energy efficient base building lighting system, which will consume less than 2 W/m2 per 100 lux, or 8 W/m2 Water efficiency strategies have also been implemented in the project.'

Another sustainable design feature is the installation of a green wall in the atrium, incorporating a unique system made from recycled material.

Atrium on 5th has been designed to encourage alternative modes of transportation. Kusano says there are cyclist facilities with lockers and showers and a preferential parking system.

With its outstanding location within the Sandton CBD and its proximity to the Gautrain, Liberty Holdings and Pareto Limited are pleased that this significant building is once again relevant to its surroundings.

They believe their investment, with serious emphasis on sustainability,is entrenching Atrium on 5th as a top business address in Gauteng. The development is due to complete in mid-2014.
