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.
This custom tiny house has a traditional cabin style exterior with a rustic modern interior that blends white walls and cabinets with warm wood accents. I would do one of those combined washer/dryer combos and make more counter space!
