The two wings of the building are connected by 3 no bridges at each floor in a glazed atrium supported on a steel structure.

Elevational Treatment

The style of the building is contemporary and reflects the high tech nature of the park.

Careful consideration has been given by the architects to the lower levels of the building, permitting it’s function, say offices or cafe, to inform the landscape as it addresses the pedestrian pathways and roads/cycle ways. The design of the façade and the transparent nature of the atrium within One South County has been formed to control and regulate the impact on open space and the public realm and minimise shadowing of the built environment and the woodland.

Glazing

The façade treatment of the building will be largely full height curtain glazing with capped glazed colour coated aluminium framing to the main elevations and insulated metal or shadow box spandrel panels. The glazing is to be double glazing, high performance and clear in nature, with low E transmissions and an approximate G value of 0.34. There are no opening sections in the glazing as the building is fully air conditioned.

The building incorporates a ‘floating or billowing veil’ feature glazed screen which wraps around part of the building. This feature over sails the parapet to create ‘movement’ and interest.

Atrium

The Atrium will consist of a double glazed sealed system, forming gables and a roof to the heated 5 storey atrium space which permits circulation between the two building wings via pedestrian bridges with glazed balustrades. Access to the reception located at ground level beside the lift banks in the atrium entrance hall, is via hinged and/or mechanised revolving glazed doors.

Stone elements of the building will be finished in a light colour quarried or reconstituted granite.

External Terraces

Selected composite decking or granite faced paving on support feet with proprietary planter boxes.

The main roof will be finished in a sedum green roof to minimise rainwater run off and protect the roof finish from harmful ultraviolet radiation.

External plant equipment will be housed behind metal louvred screens either side of the atrium in the centre of the roofs.
