floor couch idea Corner Suite Vento (price upon request): Here’s a spacious corner couch that can easily be transformed into one double bed or two twin beds, making it the perfect piece for those who love to entertain but are short on space
The couch/guest bed opens up to reveal storage, a 40 gal water tank, and water filter. An onboard 3 stage Doulton filter system originally designed for freshwater boaters makes collected rainwater water potable for shower and sinks. -- Minim Homes
For the basement stairs: cabinets, stairs with flip up steps and very narrow stairs. Each step goes up one at a time for each foot. It is sort of spaced so you are putting one foot per step with a steeper step. Very space-saving.
