Waterside houses by Will Alsop, Sarah Featherstone and Piers Gough ( pictured) were among a group of eight new homes to be unanimously approved by the council.
Property developer Jeremy Paxton has brought together 22 designers to build 50 luxury houses on his 223ha, privately owned Lower Mill Estate - a nature reserve outside Cirencester, as previously reported on ajplus ( Global architects line up for Cotswolds homes)
The other schemes to secure planning permission include homes by Alison Brooks, Sutherland Hussey, Eva Jiricna and Roger Sherman.
Richard Reid, who has already built one house on the estate and helped mastermind the development with Paxton, was also given the nod for another opulent, one-off home in the former quarry site.
Speaking after the committee meeting, a delighted Paxton said: 'This week's approval is a fantastic breakthrough for British architecture, for it is the very first time such a collection of avant-garde properties can be built in the UK.
'I believe it will pave the way for more forward-thinking country-house architecture.
He added: 'This is a serious collection of unique, modern homes which truly puts this lowland area of the Cotswolds on the world's architectural stage, while at the same time successfully blending with the local landscape.'
