HENLEY councillors say they are “not convinced” that The Henley College would be able to relocate to a single site.
The college has offered its two campuses for housing development under the joint Henley and Harpsden neighbourhood plan.
It also put forward a smaller parcel of land it owns behind Henley Youth Centre in Deanfield Avenue.
Public consultation on the first draft of the plan, which identifies where up to 479 new homes could go, closed just after the offer was made, so may have to be repeated.
The working groups of volunteers who devised the draft plan could also be reconvened to decide whether the three college sites are more suitable than the nine they have already selected.
