I 'spect this is old hat but have you tried taking yourself for a (mental) walk through a building........I visualise every detail from the hall to the 33rd ( if necessary) bedroom......colour, furnishings,purpose, books, bed linen.....every little thing until the place is more familiar than home.....mostly I don't get further than the library...on bad nights, the 5th bedroom......and as I said, on one very bad night, the 33rd bedroom but as mental chewing gum, it works.
