They join architects Stride Treglown and engineers BuroHappold who have already been appointed on the scheme.
The project which aims to provide a new stadium for the football club alongside new community facilities and the regeneration of Twerton High Street.
Championship club Preston North End’s striking Deepdale ground was led by FWP and the National League club AFC Fylde’s new home at Mill Farm is another award-winning project from the FWP team.
FWP is also working with Scunthorpe United to design a striking 12,000 capacity all-seater stadium and has created stunning new facilities for Fleetwood Town, Peterborough United and Oldham Athletic.
Brad Grime, FWP’s associate partner, said: “In all our sports sector work our aim is to deliver real destination venues for sport, leisure and entertainment for the whole of the local community, with real benefits for clubs and their supporters.
“The talent on the Bath City redevelopment team will ensure a winning regeneration project that benefits everyone.”
Nick Blofeld, chair of Bath City, said, “We are entering a key chapter in the life of the club.
“Our proposals for a partial redevelopment of the ground and an upgrade of the facilities will see us “fit for purpose” again, not only benefiting the Club, but also the wider community.
“Now we are community owned, we are determined to keep Bath City in the heart of Twerton and make it a key part of the community.
“We are very pleased FWP have joined the project team as they have recent, very relevant experience.”
