Bath have been granted planning permission by Mendip Council to begin the transformation of Farleigh House into the club's new headquarters.
The 17th century manor house was acquired by Bath's multi-millionaire new owner Bruce Craig on a 99-year lease and the redevelopment will include turning the chapel into a new gym. Work will begin on the first training pitch while the house will become Bath's administrative centre.
Chief executive Nick Blofeld said: "We were delighted to hear the news that we had been granted permission. This will now enable us to move the admin staff out to Farleigh over the next few weeks and then hopefully the first team squad in early October."
He added: "Farleigh House is a real statement of intent for the club, and to have an elite training facility and everyone in one location will be a big step forward.
"It will be fantastic to finally be able to start using it as the Bath HQ."
