Afternoon all

The house search goes on and we have a few more for consideration. Garages are always an issue, the either don’t have one or they are single and won’t fit a car in at all.

I don’t like wasting sellers time so it would be good to qualify some out before viewing. My question is…would the below garage be suitable to build above? I’m thinking I could install a small lift, meaning the car could be raised and the space below used for winter storage etc whilst soon. Even park below it.
There are two houses similar to this..




Go up say 1500mm or so to accommodate

Thanks!!

Its not a planning question if they are "ok" or not - thats building regs and the answer is - it depends. Until you had dug out the foundations (assuming there are some) and checked with building control I doubt if there is any way to tell.

Assuming the garage is single brick I would assume you'd need to create a cavity wall there anyway? in which case the original foundation probably needs widening at least ?
I would budget for the garage being removed, new foundation dug and build up from there.

No expert on planning but I reckon you'd need it.

Edit: not exactly clear on what the boundary line consists of there, but consider it might be a party wall too ?

Assuming that white line is the boundary, yes it would need planning permission.

It's certainly possible from an engineering perspective, but depending on the existing building (wall strength, foundation depth, etc) it could involve anything from just sticking some more tiers of bricks and a new roof on top to knocking the whole garage down and starting again with new foundations. You'd have to get a structural engineer involved to work out which.

We extended over a double garage (putting in an extra bedroom) and the existing walls were left up but substantial pillars were added for strength (and to hold up the floor) and the foundations were significantly modified.

We wouldn’t be extending to live above it, just raise the hight to be able to get a lift in there.

If it was demolished, new footings etc.. then it would make sense to send a little extra and add a room above, if possible.

1.5m higher for the garage AND a room on top? You'd need to add stairs on the inside because it would be split-level.

It would be far easier (and probably cheaper) to demolish and rebuilt. You will 100% need planning and building regs.

Maybe remove the current roof and extend the height you need by some kind of timber pitched roof design ??

Unless you find a property with the garage you already want I think you're destined to either alter or build from scratch. I think you're going to need planning regardless - even under permitted development you'd be limited to 4m max height., bulding rgs would be needed too.

Do you really need a lift? its going to cost a significant amount of money imho.

We had a single storey attached garage with a single skin wall on the outer side. Flat felt roof.We wanted to replace the roof due to age/starting to need more patch repairs.
Thought of options.....
Like for like or grp or other flat.
Shallow pitch tiled
Then thought of cost of adding another storey for a bedroom.
Did the sums, decided on the extra storey.
Footings on outer single skin needed widening ( underpinning was deemed ok by BC A test dig to check by BC then underpinned at a less than guessed at cost). We had a landing window ( similar to OP).that was converted into a door into the new room.
So, single skin was made into double skin on upgraded footings and extra bedroom added. Yes, cost more but improved the house both from use and future selling potential.
Garage interior height was not raised. So, if the window above the one in OP photo can be accomodated then footings can be beefed up if needed and garage slab made ok for a 2/4 post lift. If just a scissor lift then easier.
This was several years ago so modern BC/Planning/Build cost need looking into.
From my similar (ish) experience what the OP is asking is possible depending om planning/BC regs/money. Worth considering and getting enough answers when looking at the house potential for the job.
