Help with garage plans

[malcolm]

I have a shed to repair. The right side is utility room and the left side currently just shed. It occurred to me that if I continue the shed backwards to the brick barn then I would have a double garage. Currently the shed is about 9.5m long, 3m deep with 2.8m apex and 1.8m eaves.

I'm struggling with the roof design and I'm hoping for ideas. Here's a photo of the shed with the brick barn in the background.



I can figure out a good roof line for a single garage in the middle of the shed. It's the second one to the right I'm struggling with highlighted by the thin red line. It sits under a very messy willow tree so shallow slopes or flat roofs might be problematic for leaf litter.


Something like this might work. I'm a bit limited on heights - the eaves on the brick barn are 2.5m so I would need to go quite low on the garage eaves at that side to get a reasonable pitch for a slate roof. For a 20 degree pitch the ridge would be 2.8m and the eaves 1.8m which is probably not high enough for garage doors. A 30 degree pitch would make the ridge 3.1m and the eaves 1.4m. I suppose that would make it easy to clean out the gutters but garage doors still an issue.



Any ideas would be most helpful. I find when I'm working on my own I make really bad decisions so it's good to bounce ideas off other people.

I presume you wouldn’t want a flat roof coming straight back to the barn off the ridge of the existing shed?

Could you do a mansard style roof as a bit of a compromise?

Or being really radical you could do a butterfly roof coming off the ridge of the original shed down to a valley in the middle, then back up towards the brick barn?

I suspect I might not be being that helpful

Where exactly are you wanting the garage doors to go, on the wall shown in the photo, or at the right hand end where the door is on the shed currently?

The garage doors would be facing the camera in the photo. I suppose I can control the eves height above the doors by having the front face of the shed all the way from side to side as in the photo. I would need to raise the eaves and ridge by 20cm.

Actually that would hide the ridge line of the bit that goes back to the barn from the driveway side, and from all the other angles you can't see both sides of the roof at once. So the roof going back towards the brick barn can be asymmetric. And it wouldn't be a bad idea to have gutters I can clear without a ladder on the tree side. That was helpful.

Apologies as having spent 10 hours at my desk today I can’t face going back in to fire up my CAD package so crappy sketch it is.

This was my radical butterfly idea, effectively creating a significantly taller frontage to facilitate double garage doors - you have enough space for posh electrified roller ones

Would involve major surgery to the existing shed but would maximise height - might need to play with the location of the valley a bit to get your pitches right.
