Conversion to double garage - brainstorming ideas

Hello everyone,

I need your collective intelligence for brainstorming.
We have two garages plus a shed next to each other. I’ve attached a small drawing.
The whole thing is built with masonry and has a concrete ceiling.
Here’s the problem. The damn doors are simply too small to drive in properly, since the driveway is in the middle of both garage doors and then widens shortly before the garages.
I can only get in properly with folded-in mirrors, and that’s even though we don’t have a big car and actually have a larger one planned.
Also, the garage is very low, especially at the very end you can already hit your head :D

What options are there to turn these garages into a double garage?
Removing the wall in the middle and then putting in beams will probably be difficult because everything is already so low.
Are there cost-effective ways to lift the concrete ceiling, then build up the walls and insert beams so that I can tear down the intermediate wall?
Or tear off the roof, build up the walls and put on a new roof?
I just wanted to ask what can be done that is still somewhat manageable in terms of effort and cost.
I’m happy to do as much as possible myself.
Thanks in advance for your help.

Regards
Martin

The whole thing is built of brick and has a concrete ceiling.

Welcome to the forum. Then the garage was built for Golf1 and the like. Either get rid of it and build new or only drive cars of that size from now on.

Thanks for the warm welcome :) Tearing down and rebuilding was of course also considered. Maybe I need to take another look, but the costs were already steep for the size.

Photos, photos, photos - also of the driveway. That some questioners are so dense as to not put themselves in the shoes of those willing to help for a five-penny fee will be the death of me :-(

Good evening as well. Of course, I don’t want to cause a mass extinction among those willing to help here. I thought the drawing might suffice. I can gladly take a few more pictures tomorrow.
Still wishing you a relaxed evening.

We also had such a garage on the property; during the demolition, the dilapidated condition became apparent. Covering with tarpaper up to 3cm thick, leaking, wooden boards underneath rotted, if we had removed a retaining wall, the roof would have completely collapsed. The stones of the walls were partially loose in the bond, built in 1938 as expected.
