outbuilding attached to house

[Jupiter01]

I want to build a small (2mx2m) wooden shed like structure which will be attached to the house. I plan to use it as a utility and storage space. Where it joins the house, I have an existing soffit and gutter. I was thinking that I would go underneath this and not interfere with any of what is already there and then flash it into the existing wall. By the time I allow for the height of flashing and roof joists in this new structure, I wont have much floor-to-ceiling height in this new space. I wanted to check if there is a common solution to this?

Thanks in advance.

I assume it is a bungalow.
You may not even need flashing if it is under the eves.

Step the roof under the overhang. Ceiling joists only need be 75mm, use fence posts.
Why flashing if it's under a soffit? Not needed.

Not especially no. You could go to the trouble of digging the footprint of the shed downwards so that the deck of the shed is level with the outside slabs. Few would though. Presumably the door sits at the high end whilst the storage will occupy the low end.

You could get away with flashing, but it might be a nuisance in the winter, if drifting snow gets blown up there and melts..

It's a house but this is against the ground floor which is sticking out. I could slide the new roof under the existing soffit and use 75mm raters. There will be a slight fall on this new roof but I was thinking that if water splashed near the start of this, it may travel up and under the existing sofitt.

Depending on the prevailing wind you might indeed have trouble with snow melt or even blown rain being a problem. It will be easier to prevent it now ( perhaps with flashing ) than trying to sort it out later.

Inclined to agree. But flashing requires around 200mm (?) gap between the existing soffit and the top of my new rafters. I then have the height of my rafters. Am concerned about what height will be left in the actual room itself.

A shed attached to the house may well be considered an extension.

Check the permitted development rules, ensure it's OK as both an outbuilding or extension, just in case a busybody neighbour wants to cause trouble.

You'd be better off extending the roof and having decent headroom. It's not necessarily vastly more complicated, it probably doesn't need much or any alteration to the existing roof, just butt up to it.

There are no doubts about it, once you attach something to a house it is an extension. That's said most BC departments have half a brain and will see it for what it is ....

Do you have any pictures on what this might look like please? I am struggling to comprehend it.

Would it be a "lean to" - is that still a thing
