I want you to throw some ideas at me regarding my dad’s garage, or perhaps more specifically, the widening or conversion of the typically British narrow garage doorway.

He gets his Mustang this week, and while it *just* fits through, it’s only by 5cm on either side. Knowing my old man, he’ll prang it.

The central pillar cannot be removed or thinned without replacement of the lintles with a full width RSJ and double-and-a-half wide door, an expensive option - so the current idea is to partition the two garages, remove the left hand garage door and framework effectively turning it into a car port and giving an extra 10cm of leeway on each side. That’s 15cm (6in) in total on each side and not unrealistic, while still remaining cost effective. We’ll also install a drop-down pillar into the front of the car port for when he’s away on holiday. He doesn’t want to leave it outside, so are there any other options?

Is it really hard to replace the lintel (I-beam for yanks)? I feel like converting one into a carport would be just as much work.

Edit: Honestly I’m kind of surprised that it isn’t a single lintel, maybe go with putting in a single lintel and then just widening one of the doors a tad.

I would widen both doors by replacing the center brick column with a much narrower steel support post. He could then stay with two openings that are a standard size and will much more easily accommodate his new Mustang. Also, replace those old cumbersome panel doors with sleek roll-up doors while he’s at it - they make garages SO much more usable.

Currently it’s sitting on two L lintels which would need replacing with a single RSJ (I-beam), so it would require external support of the roof trusses and full deconstruction of the top section of brick/blockwork. He’s asked for a quote to see ££££, but the garage door alone will be quite expensive.

Does the car have folding mirrors? There must be a couple of cm there for a start.

What’s the thickness of the wall? Solid brick or brick/block?

Hmm, bugger. I guess the carport would be a good option then.

From the picture it looks like the outer wall has a slightly narrower opening than the inner wall. If that is the case I can inagine that the opening could be made wider by sawing/grinding off a bit of the outer wall, so that it is inline with the inner wall, and installing a slightly wider overhead door.

It looks like the blue door fits inside a white door frame, which itself fits inside the masonry opening. I would remove the door and frame, and then get a new door whose frame attaches to the front face of the wall leaving the full masonry opening clear.

Remove mechanicals, saw the Mustang in half lengthwise, remove 10CM, reassemble.

Brick outer with brick/block inner with insulated (styrene) cavity circa 50mm.

So leave the steel support as is (no cladding or surrounding brickwork) and build the roller doors onto it?

It may look a bit odd against the house, but it’s a damn good idea.

They are actually the same width, trick of the angle I think, and the garage frame doesn’t help matters.

Yeah, you’re looking at I-beam if you’re cavity construction. I’m a licensed engineer in the states, was hoping I could give you a tip. Cavity is tough to work creative solutions on.

We did consider that, but as you can possibly see in the pic the top half of the garage is rendered and sticking out further still is the lintel at the top. The frame would have to be about a foot deep just to accomodate the profile of the garage and the garage door.

Sort of, except from the exterior there would still be a (narrower) brick “column” ~1 - 1.5 bricks wide so it shouldn’t be bad aesthetically. The beam would be visible from the inside but, hey, it’s a garage so who cares?

So if the brick is just facing, would the roller doors be able to attach to it? I don’t see it having much lateral stability (front to back), or would the brick tie into the pillar somehow?

The steel pillar would need to support them both; just use brackets welded to the beam. The roll-up doors are anchored to the upper span, the side spans just need to support the door’s track laterally - fairly easy work for a steel support member.

Thanks all the same

We had about that much room on either side of my wife’s Altima in our garage, (maybe a smidge more - couple inches on either side.) She never tore the mirrors off, but scraped the tips quite a few times. I’d just buff it out and not say anything... That ‘stang is even wider - it’s got to be super tight... are the mirrors folding?

Any pictures of the inside structure showing how the lintels are supported between the doors? Specifically is that block column entirely structural, or is the block hiding a steel column that is actually supporting everything? Do the two lintels butt up to each other between the doors, or do they just catch the edge of the block column?
