Harlequins have announced plans for a new centre of rugby at Surrey Sports Park.
Quins have reached an agreement with the University of Surrey, owners of the Sports Park, near Guildford.
The new centre, adjacent to Quins' existing training pitches they have used since 2010, will include changing rooms, medical suites, video and statistical analysis suites, meeting rooms and a lecture theatre.
Reigning Aviva Premiership champions Quins say work on transforming an existing building will start immediately, with players, coaches and support staff moving into the centre next September.
Quins chief executive David Ellis said: "Our players and coaches deserve the best training facilities that the club can afford, and now they will have them.
"This development represents a major investment by the club, and we are grateful to our owners and to the University of Surrey, in particular to the management of Surrey Sports Park, for making it possible.
"As part of our commitment to the park, we will identify future opportunities to share our knowledge and experience of the sport with members of the University community, and support any related academic programmes, research or teaching in an active and positive way."
