It’s in a very luxury holiday complex of other holiday homes on the water park, and there’s a premium on it for that. You wouldn’t be buying it to live in but to let out.
For that money in the village itself or just around you’d get a fairly large period vicarage or equivalent with good gardens, if you want to live here.
I might be biased about the area, but it is close to anywhere nice - not far from Cirencester and all the lovely villages we have round here, typical Cotswolds, close to places like Kelmscott and Bibury, some of the most picturesque places around!
