It was purchased and renovated in the 1980s by Clwyd County Council into offices as part of the technology park to develop hi-tech services to assist the neighbouring medical institutions, such as Wrexham Maelor Hospital.

It is situated within a fully glazed atrium, which links the main parts of the hall with the NHS Medical Institute.

The hall is arranged in a shallow U-plan, with its entrance facing the west, while its wings enclose a small courtyard to its east.

[1][2] The hall lends its name to the general area which may be also known as Croesnewydd, centred around Wrexham Maelor Hospital, as well as the former large steam locomotive, marshalling yard and railway junction within the area known by the derivative Croes Newydd.
