Swansea Council say contractors working on behalf of National Grid are now on site in the square, with all businesses in the area trading as normal.
The work will see high-voltage cables moved and re-laid to reflect the needs of the square’s new design.
National Grid’s access to the square will mean that pedestrian access has been temporarily re-routed; the square and shops remain open.
Council leader Rob Stewart said: “It’s great to see work moving ahead at this pivotal location; our new-look Castle Square Gardens will be a fantastic place to meet, spend quality time and enjoy public events and gatherings. We thank the public for their understanding as contractors work on these vitally important cables.”
The council say that main work on Castle Square is due to start in this year and is due to be completed around a year later.
The transformation will include two pavilion buildings for food, drink or retail businesses, an increase in the amount of other greenery, including new lawns and planting, a new water feature for interactive play, new giant TV screen and bandstand-style facility, outdoor seating areas and the retention of public-use space.
It is planned that the leaf sculpture will be moved to another suitable Swansea location.
