The two brothers were known locally, and their charitable trust later paid half of the construction of the Wrexham & East Denbighshire Memorial Hospital following World War I.

[1][3][4] The original buildings were of red-brick with dentil eaves, and slate roofs with reticulated keystone to brick voussoirs and stone plinth.

[3] In November 1873, through the Wrexham and Denbigh Weekly Advertiser, a tenant of a local farm requested the brewery reduce their in-take of brook water by their brewery's main sewer, as the over-dilution of the sewage and the excess sand it brought with the brook water became "very embarrassing" to the tenant.

The brewery did not respond, although the tenant expressed their intention to re-lay the surface pipes, that would have needed to be done to tackle the issue.

The sale was held for "the winding up of [the] estate" and concerns over the increasing old age of John Jones, the last surviving owner of the brewery.

[3][4][5] The former Island Green Brewery, including its former malthouse, were listed as Grade II buildings on 9 July 1981.

[6] Following a photographic survey of the old brewery site by the Clwyd-Powys Archaeological Trust in July 1981, the buildings were found to have been built with red brick, with dentil eaves and some with stone mouldings and other detail present.

In the southern outer courtyard, there is a former three-storey malting range and twin kilns, which are bounded by brewery buildings to their west and north.

[5] The remaining brewery buildings have since been restored by the RIBA–CIAT Lawray Architects, and converted into 34 residences in a project costing £2–3 million.

[6][9] The retail park was built on the site of the original Wrexham Central railway station, and the former Island Green Brewery.

Some of the retail park's occupiers, as of 2023, include Asda Living, Costa Coffee, the Food Warehouse, Next, Poundland, Smyths and Wilko.

It would have demolished the nearby St Mark's Multi-storey Car Park, and included a potential new cinema.

This led to visitors, such as those who were dropping off or picking-up passengers from Wrexham Central, a railway station adjacent to the car park, or those picking up pizza,[17] being fined £90 for lack of payment.
