“Due to the exposed marine environment and the consequent need to provide a robust outer skin to the building, concrete is proposed as the structural frame and main building element for the shells. The inherent quality of concrete and the construction process lends itself to manufacturing the complex shell forms and the concept design explores the possibilities that concrete offers. Through design development the shells could be manufactured locally using repetitive moulds and the tough outer skin can be produced with textured form work to create the rough texture reflecting the oyster theme.”
“In contrast to the robust and textured outer weather protective skin, the internal walls will be a smooth plaster finish, with an almost pearlescent finish, reminiscent of the natural make-up of oyster shells. The internal make-up of the shells will be adaptable to suit the changing needs of the Visitor Centre and will be easily maintained. The space between the outer and inner sandwich skins will contain service voids to service the galleries and provide a high level of building insulation.”
