Single storey PD extension that will require existing Garage to be Rebuilt

[Chunkytfg]

Looking to possibly in the future extend our house(not that we have even bought it yet) with the usual 3m Single Storey Extension out the back with Bifolds etc however we have a Single garage set back and to the side from the house but on the same line with the edge of the house.

As the garage has been there since the 60's and as far as we know still has the original roof and therefore asbestos in it (original plans for garage specify asbestos roof) will need to be dealt with. We were planning on maybe making the garage into a gym space (not Habitable but coat of paint, free from draughts etc) so knocking it down and starting again seems like maybe the most straightforward approach as the corner of the Extension will share a wall and access door with the garage.

As things are at the moment the house has a nasty unusable Conservatory on roughly the limit of PD but its cold, un heated and falling apart so needs to go.

Ignoring the cost aspect of it would the knocking down and subsequent rebuilding of the garage change the likelihood of the extension being allowed under PD?

TIA

If you demolish the garage it will surely require permission to be rebuilt, under pd or otherwise, so a risk either way, whereas if its kept the project can be considered as a whole with the new garage and conservatory being viewed overall as an enhancement.

The Council might be willing to advise on the pd position.

As long as the garage and back extension are not physically connected, both should be OK under permitted development (subject to the usual criteria being satisfied).

I wasn't thinking of demolishing it straight away but doing it as part of the extension. So in essence taking it down so sufficient footings can be put in place to support the extra weight on the corner that will join the Extension.

As long as the garage and back extension are not physically connected, both should be OK under permitted development (subject to the usual criteria being satisfied).

So if I want to join them to allow access to the garage from the extension I would need PP? Currently the Conservatory is on the garage corner creating an indoor route to the Garage. If thats the case it will probably be better to move the garage back further into the garden keeping them separate and maybe allowing for a wider than current Garage/ future gym.
