The next stage of the £11.5 million redevelopment of Fratton Park will begin in the North Lower from January.
This will ensure that the club can restore 100 per cent capacity to this area of the ground, as well as improving levels and sightlines throughout the stand.
The work will also deliver 12 new spaces for wheelchair users and their personal assistants, add kiosks, increase milling areas in the concourses and increase WC toilet facilities for female supporters.
Safety will be enhanced through wider staircases, additional safety barriers, renewed LED lighting and electrical works.
There will be a net increase of 600 seats across the North Lower, representing another step towards increasing capacity across Fratton Park.
The first stage of works will take place across the whole of Blocks A-E in the North Lower, meaning these areas will be closed from the new year, starting with the League One home fixture against Wigan on Saturday, January 8.
It is expected that this work will be completed in May 2022, with work then commencing on Blocks F-K over the summer.
More information will be communicated to supporters seated in Blocks F-K should this work have any impact on the start of the 2022/23 season.
In the meantime, the club have set up a North Lower season ticket holder working group with a number of affected supporters to try to deliver the best solution to this complex process.
Season ticket holders in Blocks A-E will need to select a new seat for the home fixtures from January 8 until the end of the current season. The club have today (November 9) written to those season ticket holders who are affected to take them through their options from January and the process to confirm seats. Those season ticket holders in Blocks F-K will be unaffected during this period.
When the works are completed, Portsmouth Football Club will, in March, write to all season ticket holders again to ensure that they can continue to sit with friends and family, and have the same view (ie, areas towards the front or back and aisle seats) wherever appropriate, so that nobody is removed from the area where they may have enjoyed watching Pompey from for several years.
