An Englishman's home may be his castle - but in Ray Barker's case it's a converted broom cupboard measuring 11ft by 5.5ft.
But location is everything, and thanks to its coveted spot opposite Harrods in Knightsbridge, the miniature pad has been valued at £200,000.
And it’s just right for Mr Barker, who uses the tiny space to sleep in, thus avoiding a lengthy commute between Bath and Chiswick.
Location, location, location: The flat is ideally located opposite Harrods in London's plush Knightsbridge area. The sofa converts into a bed thereby saving Ray Barker a lengthy commute between Bath and the capital
Pricey: Valued at £200,000, the tiny apartment is worth £35,000 more than the average UK home
The 49-year-old bought the pokey space for £120,000 four years ago, the Mirror reported.
He said: ‘I do the cleaning while lying in my sofa bed. In fact, I can wash up, answer the door, make a cuppa and go to the loo all at the same time.’
The flat's two rooms measure 60.5sq ft (compared to a 72sq ft snooker table) and has a toilet, a shower which doubles up as a wardrobe, and six-inch deep cupboards.
It was converted into a living space in 1987 and bought by a secretary for £37,000.
Now worth almost six times as much, selling the flat would enable Mr Barker to put down an offer on 600-year-old Ballyfinboy Castle, which rests on two acres of land in Co. Tipperary, Eire.
But he said: ‘My cosy flat is just fine for sleeping. And it’d be a lot harder getting to my job in Chiswick from Ireland.’
Multi-use: Somewhere to hang his jacket and keep his shampoo. The shower cubicle doubles up as a wardrobe
