Work is due to start next summer with BAM Construction currently in talks with Portsmouth council about the contract.
The mixed-use community building spans over a dual carriageway and is the first phase of the proposed major regeneration of the inner city Somerstown area.
BAM Design were appointed as concept architects and environmental engineers and are currently developing the scheme as part of two stage negotiated contact secured under the EiSE framework with BAM South East.
BAM Design Director Steve Loughe said: “Obtaining planning consent is a major landmark for what has been an extremely challenging project.
“We have spent a great deal of time consulting with the local community and user groups to gain their trust and support it has thankfully paid off.
“The brief was to provide a landmark building, giving communities on both sides of the road equal access to the much needed new facilities .We also aimed to retain as much scarce open space as possible and spanning over the road achieves this, at the same time creating an iconic statement for the local community.”
