City Ground expansion estimated cost revealed as Nottingham Forest granted permission for 52,500 development

Nottingham Forest have been given the green light for a major redevelopment of the City Ground that could increase its capacity to 52,500 at an estimated cost of £790m.

Rushcliffe Borough Council's planning committee approved the club's proposals on Wednesday, September 16, marking a major step forward in Forest's long-running plans to transform their historic home.

The project will be delivered in two stages, with full planning permission granted for the redevelopment of the Peter Taylor Stand and Trent End, taking the stadium's capacity to around 45,000 before a further expansion of the Brian Clough Stand could add another 7,500 seats.

Forest receive approval for 52,500-capacity City Ground

The first stage will see the existing Peter Taylor Stand demolished and replaced, while the Trent End will also be redeveloped to provide additional capacity and improved facilities.

The plans include a new public plaza and restaurant, alongside upgraded conferencing, media and back-of-house facilities. 

The second stage has received outline planning permission for the redevelopment of the Brian Clough Stand, although Forest will need further approval for the detailed design before that part of the project can proceed.

Once completed, the development would make the City Ground the largest football stadium in the East Midlands, with the club's plans representing a substantial increase from its current capacity of around 31,000.

Forest had previously received permission in 2025 for a smaller expansion to approximately 35,000 seats, but returned with a significantly more ambitious proposal after reassessing the long-term requirements of the stadium.

City Ground expansion faces transport challenge

The planning approval comes with conditions that Forest must satisfy before construction can begin.

One of the biggest challenges is managing the additional supporters who will attend matches at a significantly larger stadium. 

Planning conditions require a new plan for crowd movement on matchdays, with a new pedestrian and cycle bridge across the River Trent among the options being considered.

Nottinghamshire County Council and Nottingham City Council, acting as the highways authorities, have opposed a proposal to permanently close two lanes on Trent Bridge, although both councils otherwise support the stadium development.

Forest will also contribute more than £4m towards public transport and infrastructure improvements designed to encourage walking and cycling. That includes £990,000 towards proposed parking restrictions around the stadium, although the precise measures have yet to be finalised.

East Midlands Mayor Claire Ward described the approval as a landmark moment for the club and said the redevelopment could help drive wider investment in the Trent Sports District. 

Rushcliffe Borough Council leader Neil Clarke also welcomed the decision, saying the authority looked forward to working with Forest as the plans progress.

FGG Says: Forest have ambitious plans

The £790m estimate underlines just how ambitious Forest's plans have become since the club first began exploring a major expansion several years ago.

The most significant point from Wednesday's decision is that Forest now have permission to pursue a 45,000-capacity first phase, while the outline approval for the Brian Clough Stand keeps the 52,500 target alive.

However, planning approval does not mean construction can begin immediately. The transport and crowd-management requirements, particularly the unresolved issue around movement across the Trent, remain important hurdles.

If Forest can navigate those conditions, the City Ground could eventually become one of England's largest club stadiums while remaining on its historic riverside site.
