80 acres? That seems quite a lot - even with new resedential blocks, which will presumably be mostly apartment blocks rather than the plush Mill Hill villas they have at the moment.
Maybe with that much space it will even be a Bethel + Assembly/Kindgdom Hall complex?
What about the presumed exodus of Bethelites in the north London congregations? Won't those congregations be much smaller and with far fewer appointed men? I know they have lots of halls shared by 2, 3+ congregations so maybe they'll be glad for the space though, or they'll just merge. So what about the Chelmsford/Essex Congregations? Are they aware they will be getting a huge influx of bethelites? Will they be splitting up?
