Garden Building

[mayennaise]

An aquaitance has built a home for his mum an dad in this back garden. This is an ex local authority house, that originally had two sheds and a loo in a building in the garden that has an electrical and water link to the main house. He demolished this original building has as built the home comprising a bedroom, lounge, kitchenette and wet room containing a loo and shower. It has extended the footprint of the original building by a few feet.
Should planning permission have been sought for this and also would it affect amount of council tax paid.

[bednobs]

almost certainly yes and yes and building controls.
can i just be clear that this is a seperate dwelling, not an attached granny annexe type affair?

[mayennaise]

not attached to the original house in any way apart from the water, sewerage and electrical connections that already existed.

Have you searched online to see if they have applied for planning permission?

[boxtops]

yes, and yes, the council tax will be for two properties.

[The Builder]

I have to say that it was a pretty silly way of going about it. I suspect that it's far too big to come under "Permitted Development" for an outbuilding. It may well might have been allowable as an extension.

It depends on its dimensions amongst other things. Also, whether it's in a Conservation Area. If the house had merely been extended, then permitted dimensions might have given them the space they needed.

Even if it didn't come under "PD", then an application for a "granny annexe" might well have been allowed under a normal Planning Application.

Any Planning problems can usually be regularised retrospectively. Building Regulations is a much more serious problem. If he built that lot without the usual inspections etc, then, quite honestly, he's a prat.

Council tax is largely academic. Tax for a separate dwelling isn't going to happen since there is not likely to be Permission given for a stand-alone dwelling.

Council Tax with an extension or annexe will simply be higher to take account of the increased amenities.
