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.
Before and various stages of after. A bit too much going on but I wanted to try some things out so I knew what we wanted in the next house.
