The Pavillon Reininghaus is located directly on UNESCO Esplanade in the Reininghaus district of Graz. It was planned by Hohensinn Architektur as a hub for the new neighborhood and built as part of the "Rein in [den] Park" project, for which zwoPK Landschaftsarchitektur created the design for the park and green axis. The pavilion houses a kiosk including a café, a small local supplier, technical rooms and a public toilet.

The building is striking. Even from a distance, the rear-ventilated and mirrored aluminum composite facade draws attention and gives a hint of the building's highlight: a diamond-shaped cantilevered, elevated glulam roof with a honeycomb structure. The primary structure of the roof consists of a diamond-shaped grid of laminated glulam beams. The openings of which were hung a honeycomb secondary structure, the lower edge of which is flush with that of the primary structure. The walls of the pavilion are designed as insulated timber frame walls.

The HASSLACHER Group supplied about 5 m³ of cross laminated timber and about 35 m³ of glulam for the project. Above all, the precise joinery of the glulam parts was the main focus of this project. The straight glulam was precisely trimmed at the site in Stall by NORITEC Holzindustrie and delivered to the carpentry Raimund Baumgartner, where the construction was assembled and then moved to the construction site.
