The interior of the Lounge Bar on the upper level is an intricate arrangement of 3-dimensional, faceted wooden panelling, acoustically treated with sound proofing material. The pattern of the panelling is a series of trees with intersecting branches. We devised a 3 point co-ordinate system to map out the pattern onto the walls of the heritage wing, given the 3 dimensional nature of the panelling and that each intersecting point had a totally different x,y and z co-ordinate. This system allowed local craftsmen using fairly primitive tools to achieve a high level of fit and finish for the interior works. The faceted panelling is finished in walnut veneer with bronze channels making up the tree pattern.
