Our sites
-
Traditional business parks
Our traditional business parks typically feature multiple mixed‑use buildings and over 30,000 sqm of workspace. Most of these sites were originally constructed by owner occupiers generally for manufacturing and industrial usage but have since undergone significant investment by Sirius to be reconfigured for multi‑tenant use and to meet the needs of modern businesses. Today, these sites offer a range of different workspace options, ranging from conventional large‑scale industrial, storage and office spaces to smaller‑sized and flexible self‑storage, office and conference room options. As a result, traditional business parks are home to large blue‑chip tenants, alongside a significant number of SME and individual tenants, supporting income durability through tenant and lease diversification.
-
Modern business parks
Our modern business parks often comprise expansive sites of over 20,000 sqm, featuring a blend of warehouses and office buildings. These parks are known for their superior quality comprising typically SMEs and individual tenants. Their scale, adaptability and operational efficiency support stable occupancy and predictable cash flows.
-
Office buildings
Our office buildings are typically well located on the periphery of major economic centres, in particular the seven major cities in Germany. They offer both conventional and flexible office space to SMEs and larger corporates seeking a cost‑effective alternative to city‑centre locations. Our office buildings provide high‑quality space that can be quickly adapted to meet the changing needs and working practices of our tenants. This positioning supports affordability for occupiers while maintaining attractive income quality for the Group.

Our sites
-
Industrial
BizSpace provides a range of unfurnished workshops and small industrial units for businesses needing space for light industrial work such as manufacturing, repairing and packing, or warehouse space to store stock. Our industrial spaces range from private, self‑contained workshops to managed workshop units where tenants have access to shared amenities. These formats support repeatable demand and flexible tenure, contributing to stable occupancy over time.
-
Office buildings
We cater to the office needs of small and growing SMEs, ranging from small units of 80–120 sq ft which are ideal for two to three people, to larger units of over 800–9,000 sq ft for companies with 20–200 people. Most office units are offered on flexible and conventional lease terms, providing cost‑effective alternatives to higher‑priced city‑centre locations. Several of our sites also contain fully furnished serviced offices where tenants are charged an all‑inclusive monthly bill which includes Wi‑Fi, utilities, cleaning and reception staff. We also have a few co‑working spaces where entrepreneurs, start‑ups and self‑employed individuals work alongside one another in a single shared space.
-
Mixed use
These sites are typically converted mills or factories which have been modernised and repositioned to provide flexible workspace accommodation and have a combination of unfurnished workshop and office space. Their mixed‑use configuration allows space to be adapted as tenant requirements evolve, supporting leasing resilience.
