Hi Joel,

This approach can be found much closer to home for you at The Hancock Shaker Village where the centre lantern posts of the round barn are held up on tensioned rod. See :-

Equally for me "Cross House" which is next to the church in Bramley, Hamsphire, England also employs this type of technology to good advantage. See :-
