Forget never leaving the house; how about never leaving the sofa? This concept by Milan-based Burak Kocak has features enough to mean that you could sit for days on end.
Called Herb, the comfortable seating of the sofa is straddled by a storage shelves on one side and a table on the other, which even holds a plant. Elsewhere, the sofa hooks up the mains to power an overhead light and provide a convenient power point for your phone or laptop. That sofa space is clearly long enough to sleep on, and the storage shelves could handle a few days of snack and supplies.
