Looking for recommendations for a log cabin or granny annexe

[BananaMilkshakeWithCream]

Hi all. I’m moving soon and need a log cabin (or any sort of cabin really) for a relative to live in. We were going to get a shepherds hut and have it winched in by crane but have been told that this is unlikely to be possible due to height of house and length of garden. Anyway, now we want something that can be built in situ. Any ideas please?

You need planning permission if it is to be habitable.

What facilities will it have, is it going to be self contained or just a summer house with a bed in it.

It will have a kitchen and bathroom. Basically a little studio flat.
