Just had an enjoyable few days in Dumfries. An excellent B&B, with bath and
shower, but.....

The house was an 'arts and crafts' inspired place. Our bathroom had been
constructed as a 'box' inside a well-established lean-to conservatory.
Although the conservatory wasn't readily visible from the areas open to
guests, we could make out the shape of the 'box' inside. I have a suspicion
planning would probably not have been granted for a 'proper' fully
weatherproof extension, given the nature of the building as a whole.

Is building an extension inside an existing conservatory a loophole?

IANAPlanner, and I know even less about Scottish planning rules, but I
suspect, like their English counterparts, they wouldn't give a stuff
on whether an extension had a solid or a transparent roof (unless the
building is listed or in a conservation area, etc.).

I think Scottish building regulations were tightened a few years ago
to reduce the size or use of exempt conservatories, and I suspect that
they, like England, would not exempt controlled services or fittings
even in an exempt conservatory.

No, I would have thought your B&B installed a bathroom on the cheap.
They had an existing roofed building, so simply stuck a bathroom in
the corner.
