Moving the YMCA into the former private boarding school has had its challenges.
"It's taken a while to decide how best to use the facility. We've been moving things around," Mr Tunnicliffe said.
The Y has already had some temporary tenants through word of mouth - specialist teachers working for the Education Ministry, and Plunket's carseat scheme. Groups like St John and Sustainable Whanganui have used space for events.
More is possible, and there are a range of spaces to choose from - an amphitheatre for outdoor concerts, a boardroom, a kitchen, offices, classrooms and grass and concrete outdoors.
Mr Tunnicliffe is looking for groups wanting short- or long-term leases, and preferably groups with similar aims. Cost-sharing for services such as reception is possible, and the building has ultrafast broadband.
