Tape, plastic, metal — all the essential ingredients of a warm welcome. There’s so much going on here, so much aftermarket iterative change, from the built-in doorbell button, to the intercom speaker, to the standalone button reinforced in a protective container and then labeled “BELL” because the whole thing has gotten so complicated — and heck, why not replace the key with a keypad while one is at it. This is a marvel of domestic hodgepodge, of the not so much dark side as the deeply mundane side of DIY. It takes a lot of care to not care this much.
