CannaRoomz is a new bar in Prague that leans into what many renovation teams try to hide: the raw structure. Designed by BekArch and completed in 2025, the 610-square-foot space occupies the basement of a residential building on Sokolovská Street in the Karlín district. The interior is organized around the original brick vaulting, which was meticulously restored and left visible to create a sequence of intimate bays.
Instead of boxing out mechanical systems, the design keeps ventilation ducts exposed and uses them to support climbing plants. That approach keeps the ceiling plane open and makes sure nothing visually competes with the brickwork that defines the room.
At the front, guests meet a bar counter finished with vertically arranged glossy green tiles. Integrated lighting and the tile’s rustic texture create reflections that make the counter a focal point. Overhead, a custom structure with ivy and frosted globe pendants casts a soft light that still lets the geometry of the vaults read clearly.
Farther back, the palette shifts from green-and-white marble to deep emerald velvet booth seating, with concrete, brick, and plantings balanced so no single material overwhelms the space. As lighting changes at night, the vaults continue to guide both the layout and the feel of the room.
For mason contractors and restoration crews, projects like this underline a simple point: when historic brick vaulting is the finish, not a substrate, every repair shows. Coordination matters, too. Exposed ducts, lighting, and any new attachments need to be planned so the masonry stays the star, and the historic character stays intact.
