MODERNIZATION   We continuously invest in the quality of our properties and create modern office space that will remain attractive for our tenants in the long term. The continuous quality improvement increases the company value permanently.

GROWTH   Through selective acquisitions, we continuously expand our portfolio and generate steady corporate growth. The increase and optimization of our portfolio furthermore creates synergies in the management of our assets.


alstria owns and manages a high-quality portfolio of office properties in the major German office centers. Due to our local presence and many years of experience, our team has in-depth market knowledge and develops detailed concepts for each individual building. Modernizing the properties is an substantial part of our integrated business model, on the basis of which we create consistent value.
