A couple gave up their jobs to live off-grid in a shed and built a $43k-a-year Airbnb business.

John Kernohan, 62 and his wife, Fin, 45, sold almost all their possessions and moved into a 304 square-foot shed structure costing $6,500.

They spent a further $6,000 kitting it out with furniture and electrics - as well as some unique adaptations.

Despite being just 304 square feet, their space boasts a bathroom which doubles as a greenhouse, and an outdoor kitchen with a pond full of Koi Carp.

John and Fin have lived off-grid for 13 years - expanding their land as they go.

The couple, started renting out small shed's across a two acre piece of land in August 2020 and earn $43k-a-year from their "side hustle"."

John, a business owner, from Miami, Florida, US, said: "We've got a total 10 Airbnb's, they are all different shapes and designs and our tiny houses on wheels."

"We cleaned out a section of land and they are spread out for a course of two acres."

"Depending on the unit, day of the week and time of the year the price will range from $99-$159."

"We earn $3,600 a month - it's a nice little side hustle."

John and Fin met online in 2010 despite living on opposite sides of the world - and travelled back and forth between Miami and London while dating.

When John stayed in the UK for a while they rented a narrowboat to live on together and enjoyed it.

When Fin visited his three-bed Miami home, she made her feelings about the size clear.

John said: "We had a joke conversation where she said 'I don't know where this relationship is going, but I'm never going to clean this place'."

"I joked I'd hire a housekeeper – and she responded suggesting getting somewhere smaller."

"The seed was planted."

In December 2011 Fin moved to the US to live with John permanently, and convinced him to go off-grid by saying "I love the man you are when we're out in the woods"."

They started by leasing a plot of land for $1,200.

Soon they moved into their first shared home - a 304 square foot cabin in rural Georgia costing $6,500, which they paid for by selling most of their possessions.

They spent a further $6,000 on the cabin's plumbing electrics and insulation, and kitted it out with furniture and equipment before moving in permanently.

The cabin is fully powered by solar and thermal energy, as well as using a biogas system - creating cooking gas from their non-compostable waste such as leftover meat.

John said: "We are completely solar for our electricity needs. "

"All our water is rainwater collection - we have 2,000 gallons tanks."

"It is completely clean water, and we create methane gas for our cooking fuel and the biogas digester sorts our sewage and cooking waste as well - and converts it into methane."

"We have a wood burning stove to heat the house during the winter."

While small, they've made their home their own - and over the years added quirks such as a greenhouse bathroom and kitchen.

Their kitchen even features ponds complete with seven Koi Carp and eight other tropical fish swimming around.

John said the Airbnb business is booming since starting it in August 2020 and the couple even run 'tiny house festival's', workshops and events.

John said: "When we started out, I thought we made a mistake because we were always on top of each other and never had any space."

"She said 'if you want space, we have acres and acres out there, go take a walk'."

"I realised she was right, it's what you make of the space, not its size - personal space doesn't have to be a room."

"If we ever get annoyed at each other, we just get over it real quick - we resolve the negative vibe and move on."

"We have friends in big houses near us on the lake and we go there for parties - but now I can't believe we used to live that way."
