The roof/guttering situation? Had the idea when obsessively staring at local lofts; most have a step-down from the large dormer to the smaller outrigger, with the associated mess of pipes/gutters/soffits and low head-height in the outrigger. Wasn't up for this, so scoured the permitted development planning documents, and couldn't find anything that stipulated that there had to be a step-down.
I then started noticing the odd double-dormer here and there without the step-down, so drew up what I had in mind and got advice from an architectural technician about the roof pitch, then chucked it in our builder's lap. Seems OK so far, hope it holds up during a deluge lol
This also has the side-effect of achieving a grand ceiling height in the small outrigger room...

Thanks!
The only down pipe is at the front of the house; the entire flat loft roof is one contiguous surface (no step-down between large dormer and small dormer), which is pitched towards the front, so no gutters/down pipes needed on the rear/side elevations.
This can also be achieved with concealed guttering, but that’s hugely more expensive to construct, consumes internal volume, and is a proper cunt to maintain if it gets clogged/starts leaking.
As for turd cupboard: this has been pre-plumbed in case we decide to put one in later, and the waste pipe runs through the eaves storage void and out via the side passage, so wouldn’t be visible regardless.
