The Galeria Teplice shopping centre expands into the open space in the southeast corner of the building and follows the original architectural concept of alternating horizontal stripes, but uses different materials. The project also includes the modification of the existing northern entrance from Svoboda Square. A new revolving door will be installed here to replace the existing sliding door entrance hall.

In the first underground floor, the current arcade will be extended and several new business units will be created. On the first and second above-ground floors, the extension will offer an expansion of the leasable commercial areas.
