Allenmoosstrasse 116-120

Short description

Complete renovation of eight multi-occupancy homes and building extension

The project

The property on Allenmoosstrasse in Oerlikon is situated close to the centre of Zurich at the point where urban building developments and garden-city areas meet.

In addition to a complete renovation of the residential units and a building extension, the underground car park with 48 spaces was also renovated. After the building was stripped back to the support structure and various adjustments were made to the floor plan, new lift systems were added to the existing staircases. Furthermore, the existing balcony recesses were enlarged.
