Commercial grade expanding security doors from The Australian Trellis Door Company (ATDC) were recently installed at the historic Capitol Theatre on Melbourne’s Swanston Street.

The RMIT owned, heritage-listed theatre is part of the Capitol House building originally designed by Walter Burley Griffin and his wife Marion in ornate Chicago-Gothic style. The $40-million refurbishment of the theatre included the installation of ATDC’s S04 trackless expanding security doors.

The specifying architect was Melbourne based Six Degrees Architects and the project managers were Hutchinson Builders.

ATDC’s S04 trackless security doors were installed to the bar areas on two different levels of the building. When unlocked and opened, these doors fold and stack back to a compact storage size of just 12 per cent of the opening width, making them an attractive option to specifying architects and developers alike.
