Extension over a communal garage

stuuyb

Custards,

Yea there are houses at the other end.
To the right side of our house is our neighbours semi joined to us. To the left is our garage joined to our house. Joined to the left of that is our neighbours garage (the semi to our right), then to the left of their garage is another garage followed by another garage joined to that. This end garage is then joined to the side of a house.
So basically four garages in a line, a house at either end ( ours being one) and the two garages in the middle belonging to the semis at the other sides. Hopefully ive explained that right.

27col,that makes a lot of sense, I'm guessing if the foundations arnt adequate then it may make it quite expensive..... There is another house on our estate that has extended over their garage, however their garage wasn't joined to Another garage.

I was looking at getting ideas of whether planning would allow it ( im told they can be very funny) before spending money on surveys and that.

If someone else has done it chances are you'll be allowed too.

You don't need a survey, speak to planning department see if it's ok in principle. Submit plans and get permission. Dig a test hole to test your foundation. Chances are it's not upto it and needs strengthening. I bet you've s single skin wall on your garage too that will need addressing.

You could phone planning department and ask them. I have found them to be helpful.

Thanks all

Am going into our council planning office today just for a quick chat to see what they say.

Captain, think our garage wall is single skin, which must likely means expensive to sort, but hey first priority is to see if it's an achievable project. I'm told by friends (one in the know so to speak) that's there's nothing to say you can't extend but nothing to say you can....?! The council in question (WBC), im told are really quite tough and strict in what they allow, much more so than other councils nearby....great...not

to dig new foundations for your extension, you will have to demolish your garage and the garage attached to yours.

Not true! The existing single skin will have its own footings. You will need to dig out the inner perimeter floor (presumably a concrete floor about 15inch across) to expose the footings for the wall and then dig down to 500mm below this, pour in new concrete (C25 grade) and build a new internal cavity wall (75 - 100 mm blocks) off this tied into your existing single skin wall. This should adequately take the weight of the extension. If in any doubt speak to a structural engineer for best advice!

Should ensure you cant use it for a car anymore at least!

Only if op is going for change of use i.e. garage no longer to be used as garage.

Thanks rite sh, read the other post and was like really...knock the garage down surely not!

My main concern was the council saying it's feasible. I spoke to to the duty planner today only for a few minutes and to be fair all he really did was refer me to wbc design guide, though he thought extending over garage should be fine ( even though it's joined to other garages), providing the guild lines online are followed.
He referred to a pre application that you can do...

In terms of the garage seems a structural engineer maybe the way forward, though I'm led to believe for them to access it we are talking big money, in the region of 2k plus (their drawings, digging into garage etc), seems very pricey
