The house, slotted between two other properties in the capital, opens out dramatically at the back, providing comfortable open-plan living spaces and a substantial garden.
Huge glass panels allow natural light to flood in and there’s also a roof terrace on one of the three stories giving a view of the garden.
When it was put on sale, the illusory property was listed at £,1250,00 and was sold, subject to conditions.
In their description of the property, Rightmove said: “In the same way that the TARDIS is much bigger on the inside despite its exterior being of limited size, the same is true of this impressive property.”

They added: “Remarkably, the Coach House extends to 1,621 sq ft across three floors, with a modern open plan living space at the back of the property blending into a private, urban oasis of a garden.
“The Coach House has been rigorously redesigned as a ‘smart house’, with underfloor heating, an eight-speaker Sonos system in the living room and kitchen as well as video camera doorbell at the front door.”
Photos of the interior show a modern kitchen joining a spacious living room as well as exposed brickwork offset by concrete pillars.
The elegant design continues upstairs, with a simple bedroom featuring a floor-to-ceiling window and a mirror.
Rightmove property expert Miles Shipside said: “It’s wonderful to see such diverse property for sale on Rightmove and this beautifully contemporary home is definitely one of a kind.
“I love how the narrow façade disguises a quite magnificent home behind it, giving the impression that this property is almost like the TARDIS from Doctor Who.”
