50 new manhole vestibules designed by Holscher Design are currently ready to be installed in the city of Oslo. Each with a weight of 2 tons. Holscher Design’s Manhole vestibules were chosen by Oslo municipality among 80 suggestions at a design competition in 2010.
The twisted slits in the vestibules outline the spiral movement of ventilation, ensuring proper draining and protecting the surface against graffiti. The ornaments and the dynamic, sculptural shape give them character and recognisability.
The vestibules are produced at Sabro A/S Foundry and function as both ventilation and access to technical underground installations under the city of Oslo.
The broad base allows installation on the existing foundation.
