St Mary's Island – a unique place to live
Originally a series of marshy inlets, St Mary’s Island was enclosed and made up during the great expansion of the dockyard in the late 19th century. This expansion involved the building of the three huge dock basins which separate St Mary’s Island from the “mainland” and the South Maritime Estate.
St Mary’s Island is a primarily residential area, which will eventually contain towards two thousand homes. The homes are mostly being built by Countryside Properties, with smaller sectors by Redrow and Barratts.
What we do
The Trust maintain the 350 acre estate to a high standard ensuring it is a desirable place to live for our c. 5,000 residents. We look after the parks, play grounds, the flood protection system, riverside walks and cycle ways and so much more.
