I'm interested in Tiny Homes. This one in the UK is just gorgeous — After a Divorce, She Built This Incredible Tiny House and Reclaimed Her Life (30 minute video):

The design of this tiny house is incredibly clever. The space feels open and expansive, with skylights running through the centre and mirrors that reflect the sky above, making the home feel larger than it is. A bathtub tucked neatly beneath the sofa is one of those ideas that makes you stop and smile. Everywhere you look, there’s thoughtful design and smart use of space.
