Detailed planning permission has been given for a tower that would be the tallest building in the South West.
The £75m project will take about three years to complete
The site earmarked for the 330ft (100m) structure is near Plymouth Hoe on the edge of the city centre.
The 31-storey tower would house nearly 200 residential flats on a site that would also include shops, offices, and a hotel.
The £75m public open space would form part of a corridor linking the city centre to the sea at Millbay.
The plans have been drawn up by architects in Plymouth for Falmouth-based developer Devington Homes.
The project has taken several years to plan and will take about three years to build.
