During 2016 Coin Street carried out consultation about its aspirations to improve the gardens.
Based on this, a design brief to create a public open green space of high quality and sustainability was created and in 2017 a landscape design competition was launched for the north part of the gardens.
Improvements to the planting in the south part of the gardens are already under way.
Five competition entrants have been shortlisted: (Bradley-Hole Schoenaich Landscape; J & L Gibbons; Kinnear Landscape Architects; Reynolds Design; and West 8).
Their outline proposals are now ready for further consultation.
On Thursday from 7pm there will be a presentation by each of the shortlisted landscape designers, and an opportunity to ask questions and feed back views and comments.
The designs will also be on display on Friday and Saturday.
