INTERIOR FEATURE TOTAL SOUTH AFRICA INTERIOR DESIGN: PARAGON INTERIORS T IMAGES: RIKKI HIBBERT, PARAGON INTERIORS otal South Africa is an oil and petroleum company founded in South Africa in 1954. The head office is located at Total House, 3 Biermann Avenue Rosebank, Johannesburg, South Africa. Objectives The building was to be renovated, re-vamped, re-designed and meet the requirements of the new building regulations, with the focus on safety. The size of the floorplates in the existing building was to be increased by 1,000m2 to accommodate increasing staff numbers and to allow for future growth. The new head office was to reflect the global corporate identity of Total while at the same time remaining local and African. A new corporate identity for Total Africa was recently developed and this is portrayed through the interiors of the office space in Rosebank. A 4 Star Green rating is being applied for both the design and construction of the final building. Architectural Changes For the new façade, Axient Architects used a unitised façade system which was fitted to the outside of the existing concrete structure. This not only met the new SANS 10-400-XA energy efficiency regulations but also added additional floor area around the perimeter. A fully automated blind system was installed, which adjusts as the sun moves during the day. 66 The design of a new central core in the middle of the building, stretching from the lower basement right up to the mezzanine level, incorporated a new central staircase and lift. On either side of this, the use of escalators from ground to first and first to mezzanine levels was implemented. The extension of the mezzanine level within the existing skeleton of the building was made possible by the engineers at BSM Baker providing the additional 1,000m² of office space the client required. This also incorporated the necessity to re-design the roof truss structure to provide more head height in a specific grid area. The original entrance to the building was located on the East side. This was problematic in that the space was not efficiently used as it faced a taxi rank. The idea to move it to the North made sense in a number of ways. A double volume area already existed and since the sun was at its harshest in this area it made staff seating in this area impractical. The two existing atrium areas were reduced from 12 x 24m to 12 x 12m. A joint effort between the architect, engineer and interior designers brought about the innovative, cantilevered meeting rooms that now fill these voids. As part of the brief, the professional team needed to meet the Green Building Council of South Africa’s specifications in order to achieve a 4 star rating. Various systems were put in place to achieve this, from rain water harvesting to VOC free carpets. Total South Africa
