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. The St Mary’s Island Residents Association appoint two of our Trustees making sure residents voices are heard.

What our householders say...

Just wanted to say thank you for the Friday Flyer. It’s a valuable source of information and I can appreciate the time involved to produce it.

I find the Friday Flyer most useful and interesting to keep in weekly touch with what is happening in our area. Congratulations to the editor and all involved in its production.

The trees have been cut back on the crown; they look really nice now and we still have a wonderful view in the background. Well done whoever put this plan into action.
