Salford's Bnei Akiva bayit will be the last remaining Zionist building in Greater Manchester after the closure of Mamlock House, the former home to Manchester's Israel charities.
Manchester's Zionist Central Council is due to open its new offices at the bayit on October 4 as a temporary measure.
An extension to the bayit will be funded from the Mamlock House sale proceeds.
"It's a bit of a disaster," bayit director Shimon Gillis admitted. "We've got one large building, but loads of organisations are approaching us to use the bayit. It's going to be impossible to juggle."
ZCC president David Berkley said BA had "excellent meeting rooms to allow us to continue to do what we've done for the last 100 years".
