# Thoughtful Office Building Interiors Bruzkus Greenberg Designed the Shared Amenity Spaces at C1 By Kalin Ned | Published 2026-06-01 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/shared-amenity-spaces References: [archdaily](https://www.archdaily.com/1041337/c1-workplace-bruzkus-greenberg)  The architecture and interior design firm [Bruzkus Greenberg](https://www.trendhunter.com/trends/blue-box) has completed the shared amenity spaces at C1 — an office building located at Berlin Alexanderplatz. As part of this project, the studio created approximately 1,600 square meters of communal areas that blend [hospitality, residential, and workplace design principles](https://www.trendhunter.com/trends/storytelling-workspaces) across two lower levels beneath six floors of conventional office space. The shared amenity spaces at C1 dedicate entire floors to spaces that function as a 'third place' for tenants. The design venture offers a library, café, bar, cinema, conference facilities, a gym, a yoga room, and tiered arena seating that steps down to a courtyard connecting the ground floor to lower levels. The design deliberately avoids the aesthetic of a single furniture catalogue by combining bespoke sofas and tables designed by Bruzkus Greenberg with curated vintage pieces and less-common off-the-shelf products.
