Building a lean to shed

[dern]

I already have a shed on the side of my house which I built about 5 years ago. It's been great but I now want to build a bigger one. The problem is that the plot is an odd shape and I want to maximise it...



Basically I've got two questions...

At the moment the main drain cover is outside the existing shed and as I want to extend the shed it will then be inside. As this is a wooden shed and not a permanent structure is this ok or not allowed?

Secondly (assuming the first thing was ok) my current shed has a pitched roof made from corrugated transparent polycarbonate which is brilliant because I get loads of light in. With new shed being an odd shape building a pitched roof will be tricky. Has anyone got any methods/websites/advice on how to build a pitched roof on such a shape or can I build a flat roof out of corrugated transparent polycarbonate?

The wall at the bottom will be roughly 8 feet out from the wall and the one at the top will be roughly 12 feet.

Thanks,

Mark

Was going to start a similar thread at some point in the future.

We have a piece of land a similar shape to yours down the side of the garage. If money was no object i'd have the garage extended out to the wall but we can't afford to do that.

The plan for later in the summer will be to clear the area, lay a concrete base and install some sort of lean to.

The question is how do you stop water getting in through where the roof meets the garage and also where it meets the boundary wall?

The existing shed that I built from scratch is rectangular so it's all a bit easier. The roofing I used was transparent corrugated polycarbonate sheet. At the low end it simply overhangs the side of the shed. This isn't over a boundary and the rain falls on a gravel path and as the shed isn't massive this doesn't cause any problem in terms of drainage. At the house wall end I got some self-adhesive lead flashing on a roll, left it in the sun on a hot day and simply stuck it half to the wall and half to the polycarbonate pushing it on very firmly. You could route out a channel of morter and cut in some proper flashing but the stuf I used is fine and has been completely leak free for 5 years.

As long as you leave some sort of access to the drain (A trap door of some sort ) then I can't see a problem with it.

Second question is not that hard to answer if you want to go the true pitched roof way then it is just a case of building the new wall(by the fence) in a Trapezium shape ,not so good as drawing as you are but if you turn your pic so that the thick brown line is the base of it then thats the shape you need to build it

Does that make sense ?

We can practise on yours then do mine afterwards!
