As a mark of how obsessed we have become by sketchup, here's a design for a ventillation grille to be sunk into the floor of the buffer space to allow cold air to pass into the area. We're looking at oak, as it will go better with grey slate than black plastic will. Meriel has volunteered to drill out the oak in her woodwork class.
