The project involves adding a new office tower extension to an existing high rise office tower at 78 Shenton Way, being located on the edge of the Central Business District.
The existing building comprises a 34-storey tower sitting on a large 3-storey podium linked to a multi storey carpark. To overcome the site constraints, the new tower comprising 8000 sqm of gross floor area is built over and suspended above the existing multi-storey carpark deck.
The typical floor plate is designed with the service core on the west façade, opening up to a large unobstructed column free space with spans up to 21m and net areas of about 1200 sqm per floor. The choice of non centralized core allows a single large space shielded by the western sun with views out to the surrounding harbour beyond.
The overall façade expression of the new extension articulated as cubic volumes, which echoes subtly the existing solidly granite cladded tower. In deliberate contrast with the existing tower, the new extension is fully cladded in glass curtain wall, with the strong modular lines diffused by ‘dissolving’ frit or perforation pattern on the glass or aluminium cladding.
