In 2004, contracts were exchanged and the Birmingham Alliance sold the redeveloped shopping centre, raising sale proceeds of £93 million net of costs. The redevelopment of Martineau Place in 2001 had been planned as the first phase of a wider development of the area, with a second phase expected to redevelop further 1960s-era buildings at the other side of Bull Street, including the adjacent shopping centre formerly known as Martineau Square. The completed development originally received a single combined planning approval, and was to be known as ""Martineau Galleries"" when completed. However the second phase was not progressed, and the un-modernised part is now called Priory Square. In 2016 One Martineau Place, the 13-storey office building above the development (which had not been part of the 2001 modernisation of the centre, and was by then vacant, having previously been occupied by insurer Aviva) underwent a £35 million refurbishment, and was converted to a 168-room apartment hotel under the Staybridge Suites brand. In July 2015, Poundland agreed a ten-year lease on a 30,000 square foot unit on Corporation Street (following a temporary presence in a smaller unit in te centre). Burger King also agreed a 20-year lease on an 8,000 square foot unit that would become its flagship store in Birmingham city centre (relocating from a smaller and less prominent unit inside the centre on Martineau Way). In 2017, the Midland Metro opened an extension running past the northern entrance to Martineau Place, with the Corporation Street tram stop adjacent to the centre. In 2017, the owners of the centre secured flexible use categories for many of the units in the inner Martineau Way part of the development, which had seen higher vacancy levels than the main frontages on the outer part of the development, in order to ensure vacancies could be quickly filled.
