Phase 3 will combine Plots 9,10, 11, 12 and 13a of the Masterplan area, comprising the sites currently occupied by Marland House, the Wood Street multi-storey car park and the Saunders Road surface car park. It is planned to contain the replacement bus station for Central Square and form part of a new, state of the art transport interchange which will eventually integrate public transport facilities within Cardiff city centre in conjunction with plans for improvements to Central Train Station.
