From the BBC, following the journalistic guideline "Don't mention land or access to land! It's only about the physical building!":
Case One
Harriet Baggley, 24, her partner, Tom Offen, 25, and their son, Ruben, two, live in a van fitted with a log-burning stove, insulation and a makeshift kitchenette.
The 2008 Volkswagen Transporter 4, nicknamed "Iggy", has been their home since they left rented accommodation in April last year. They move their home-on-wheels to different spots every few days, spending two to three nights a week at a relative's more conventional home while helping them with child care.
They appear to be doing it the hard way, and I hope it works out for them.
Case Two
For Aubrey Fry, 37, and his wife, Clare, 34, life in a repurposed 40ft shipping container was only meant to be short term.
Three years later and the steel box is still home, sweet home. The pair moved to Hay-on-Wye, where Aubrey's family own a farm, after growing frustrated with London property prices. They wanted to keep their costs low, while building their new home and business premises on the land, and Aubrey had an itch to try something different.
Yes, the couple have access to free land. On her parents' farm.
Aubrey would also appear to be stupidest man in the UK:
"I've always wanted to develop a shipping container and make it into a home," Aubrey said. "There are millions of them all over the world, they get used once and then get taken out of action; and I think they are a good space to live in."
Correct, he actually said "they get used once"
Case Three
Tom, who lives in Porthleven, Cornwall, is hoping to build his [tiny home aka caravan], mount it on a trailer and then move it between his friends' smallholdings.
So he's an intermediate case between the Baggleys and the Frys. What will happen when his friends get tired of him, or some officious planner tell him that he's not allowed to live on a smallholding semi-permanently?
