South Dublin County Council is bringing a 2.49-hectare (6.15 acres) site at Grange Castle Business Park to market shortly which would have a value of around €3.075 million.

The site would be ideal for a headquarters office development of 21,000sq m (226,000sq ft) in one or a number of separate blocks.

The council is now seeking expressions of interest from developers keen to acquire the site or to partner with the council where the value of the site would be related to any future income streams from it.

However, the council is not interested in entering into a design-and-build and leaseback arrangement.

Grange Castle Business Park is already home to Google, Pfizer and Microsoft.

It is set on 500 acres, and is 50 per cent occupied. Some 2,500 work for companies located at the park.

There are plans to expand the park so that it can accommodate up to 7,000 workers in a range of office buildings.

Grifols is one of a range of new tenants at the park where significant expansion is already planned by Microsoft and Pfizer.
