MARS Architects Cleverly Fold Climbing Walls into Bulgaria's First Sustainable Activity Center | Communication design |
MARS Architects snagged first place in an international competition for the design Walltopia's Collider Activity Center, Sofia's first sustainable mixed use center.

Located in Sofia, the Collider Activity Center will mark the city's first green mixed use center to combine both leisure and exercise space. To tie together the site’s diverse programs, the architects inserted a series of dramatic climbing atriums into the folds of the building, creating a continuous climbing experience.
