This strategy is underpinned by our purpose to create and manage optimal workspaces that empower small and medium-sized businesses to evolve and thrive.

Our sites
-
Traditional business parks
Our traditional business parks typically feature multiple mixed-use buildings and over 30,000 sqm of workspace. They offer a variety of different workspace options, ranging from conventional large-scale offices, storage and industrial spaces to smaller-sized and flexible self-storage, office and conference room options. The parks are frequently home to large blue‑chip tenants, alongside a significant number of SME and individual tenants.
-
Modern business parks
Our modern business parks often comprise expansive sites of over 20,000 sqm, featuring a blend of warehouses for production and storage, and office buildings. These parks are known for their superior quality and are easier to manage than traditional business parks due to a higher proportion of office space. Tenants are typically SMEs and individual tenants.
-
Office buildings
Our office buildings are typically well located on the periphery of major economic centres and 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.

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.

We also have a number of co-working spaces.

Mixed use
BizSpace’s mixed 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.
