Sounds to me like a bunch of you Piggs should consider a shared-ownership situation.
An extra home is an expensive luxury and I doubt many would use it more than once a month. This is why you can rent vacation homes. Probably ends up being cheaper in the long run, though you don’t get to play architect.
Find 4 people to each take a weekend every month, cut your building costs 75% by sharing the burden, and allow yourself this luxury much sooner.
