There’s nothing more technical than a 1:100 InDesign document with a similar level of detail to what you previously posted and a couple of bad pencil sketches on post-its for the cabinetry. Massive recessed cupboard over the cistern is a game changer, it absorbs so much crap. Would recommend.
Dont suppose you have any technical drawings? I'm still playing around with the layout of mine... cant wait to start ripping it out.
