On my 31mb I have added the thermostat shower control, the digital AC/furnace control, made storage under the bunk bed(behind the drawers), made storage under the steps up to the bedroom, added hot water to the outside water port, built a pull out stove beside the outdoor fidge, lights to the pantry, added water sensors behind the walls in the basement, made extra space in the basement, made the basement walls open using magnets to hold them closed, changed all water lines to pex, added flagpole buddy to the ladder for the starlink, added softstart to the AC, put dimmer on the awning light, and I may be missing a bit......Still going to add a motion light under the sink as it is too dark, and led strip around the island under the countertop for a nightlight. Then I'm done I think.
