Swansea Council says the redesign will see more than 40% of the square landscaped with greenery, alongside two new pavilion‑style buildings for cafés, restaurants or retail, a green‑roof terrace with public access, interactive water features, and a bandstand‑style stage topped with a large screen.
Contractor Knights Brown is currently on site carrying out enabling works, with completion expected by late 2026.
Cllr Rob Stewart, Swansea Council Leader, said:
“These new images give us the clearest view yet of the greener, more welcoming Castle Square we’re creating for Swansea.
For years, people have told us they want to see more greenery, more activity and more reasons to spend time in the square — and this transformation will deliver just that.
It will bring more life back into the heart of the city centre, support our local businesses and create a place for events, relaxation and community spirit.”
Part of wider regeneration
The Castle Square project is a key element of Swansea’s £1 billion regeneration programme, which also includes major works at The Kingsway, Y Storfa, the former Castle Cinema and the McDonald’s building on Castle Street.
Preparatory works over the past year have included:
- Underground power line upgrades to support the new design
- Removal and safe storage of the Leaf Boat sculpture ahead of relocation
- Installation of hoardings with public access maintained around the site
- Opportunities for local businesses to bid for work packages
The new images will soon be displayed on hoardings around the site. All surrounding businesses remain open during the works.
