The Mackintosh Interpretation Centre, designed by Gareth Hoskins Architect, will be a permanent facility and will occupy the third floor of the Lighthouse. The Gallery will be divided by a 16m-long curved glass screen, with information on Mackintosh buildings as they are now on one side, and an installation depicting Charles Rennie Mackintosh and Margaret MacDonald's life and work on the other. Cantilevered glass rooms contain multi-media presentations on particular buildings, and different aspects of the Mackintoshes' work. gha is working with historian Alan Crawford, the film-maker Mondo Ghulam, Wigwam Digital, and Mint Design to design touchscreen interactives, films and graphics. At the threshold between the present-day guide and the interpretative section, the visitor can go up to the top of the corner tower and look out over Glasgow.
