One of the key aspects of the design was the cantilever balcony leading out from the café. In order to enhance the view and experience, it was important to ensure a level threshold from the café on to the balcony and that the balustrade did not obstruct but frame the view. The balcony was constructed in concrete utilising the building foundations as counterbalance and the old warehouse retaining wall as a prop. To providea seamless balustrade, a stainless steel handrail system was used with glass infills.
A great deal of thought was put into minimising the environmental impact of demolishing the old warehouse and creating the new Visitor Centre. All the rubble was crushed and graded and re-used under roads and the car park to minimise imported material with the excess transported to nearby sites for re-use as capping layers.
