The exhibition is made up of eleven large-scale photographs accompanied by a brief explanation of each project that visitors can gather to make up their own exhibition catalogue. The exhibition “Architecture and City” covers the past, present and future of Prof. Badia’s studio, BAAS Arquitectura. The layout is structured chronologically and reflects on the existence and role of emptiness in architecture as an asset to be preserved in the morphology of cities.

“When necessary, architecture should be able to let go of its individual nature to embrace a context and work with it collaboratively. It should accept its condition with modesty. A building is just a small piece of a larger puzzle that has grown over the centuries. The most important thing in architecture is often not what is built, but what is not built. We’re building cities, not just architecture”, said Badia.

DESSA is an acronym for Delovna skupnost samostojnih arhitektov, the Slovenian term for Association of Freelance Architects. The organization provides a business framework and a physical space for the activities of freelance architects who work in various design fields, including urban planning, architecture, interior and graphic design, and theatre set design. It was founded in 1982 by 36 architects with the primary purpose of helping architects working on private projects, as well as raising public awareness about the cultural value of architecture through publications and organizing exhibitions, lectures and tours. The DESSA gallery and office, located in Ljubljana's city centre, opened in spring 1989. The gallery organizes approximately ten architecture exhibitions each year and also participates in activities to promote Slovenian architecture abroad.
