Walls that turn 360°
Two curved glass halves glide around a circular track and open up to 180° in any direction.


The Rondo is a round glass garden pavilion made in Germany by KGT, the sister company of Hoklartherm. Its curved walls are built in two semicircular halves that slide all the way around a circular track, so you can close it completely, open it up to 180° in any direction, or turn the opening toward the view, the sun or away from the wind.
It is a show-stopping garden room, outdoor dining room or hot tub enclosure, with 5 mm tempered safety glass walls, a high-impact roof and an elegant wind-driven roof fan. Choose from five diameters, a dome or pyramid roof, and a dark grey or dark green frame.

The Rondo is designed, engineered and manufactured in Germany by KGT, the sister company of Hoklartherm, makers of the Riga greenhouses, with more than 40 years of experience.
