Hi Hafod.
I think you've seen the thread that I posted on here a while ago on Shepherds huts but I've managed to lose the contact details that I took. The site was in a garden centre on the main road near to Church Stretton heading towards Ludlow and Hereford but a quick Google has failed to locate it. If you can be patient with me, I'll be travelling that way again in the next month or so and I'll pop in again.
What my Googling did reveal however, was that there are umpteen companies making Shepherd huts across the length and breadth of the country but that some of them are asking rather high prices for their wares. The price was the main attraction of the one that I found but then of course, you've still got to kit it out with all the various mod cons.
