Active asset management helped to further reduce the vacancy rate to 4.3% by the reporting date. The renovation work in Oerlikon is making good progress and will be completed in the near future.
Active Asset Management
Züblin maintained the positive progress in lettings and portfolio enhancement in the first half of 2025/26. A number of successful lease signings and extensions with existing tenants demonstrate the high quality of the property portfolio and underline the ongoing benefits of the asset management strategy the company has implemented.
The property in Hofwiesenstrasse in Zürich-Oerlikon was an area of focus for asset management. Züblin owns a 34% share of condominium ownership in the property, which is currently being completely renovated. The work is now entering its final phase: alongside the renovation of the electrical installations and wet cells, the building security and fire safety have been brought up to the latest standards. The general areas have also been refreshed with a modern look. The aim of these investments is to position the property in the market long term as an attractive, well-maintained and future-ready location.
We were able to further strengthen the market position of the property in Morgenstrasse in Bern-Bümpliz. The successful signing of a lease with a well-known gym/fitness centre not only considerably reduced the vacancy rate, but also increased the attractiveness of the entire property. New tenants moving in over recent months have made the property much busier – an important step in being able to place the last available space on the market to its best advantage.
At Gewerbestrasse in Egg we maintained our focus on small, flexible office spaces with communal infrastructure. The redesign of around 400 m² met with solid demand: around half of the space has already been let to new tenants after completion of the work. This confirms the relevance of this approach, even if letting in peripheral locations remains challenging.
