• 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.

  • Brilliance. Where did you get that idea from?

  • the entire flat loft roof is one contiguous surface (no step-down between large dormer and small dormer), which is pitched towards the front

    Doesn't this mean raising the roofline - i.e. the back of your house is now the highest point, not the ridgeline of the OG roof, to achieve enough pitch?

    Or am I misinterpreting how this works completely (likely tbf)
