    What order do all these washers/threads/nuts go in?

    I've attached a photo of my slotted waste. I just want to check I've got the order, and orientation correct: The basin itself would be between the black plastic 'washer?' and the soft, conical rubber seal. Is this what you would expect? The problem is, I am getting a leak from the overflow...

    Screed on split level floor

    We have just dug out our basement, with a split level where one area is 600mm above the other. We plan to put a glass balustrade up to partition the two areas apart.

    Lightwell Design

    I'm in the process of building a light well for a basement conversion. My structural engineer has 'missed' this out from the original statement of work and waiting will put a 3 week delay on the whole project. Opinions on whether or not I should continue with/without the calculations aside...

    Advise on floor layout
