A penthouse apartment in an art deco building in the heart of one of London’s most exclusive boroughs would usually set potential buyers back millions.

So this one at £400,000 in Knightsbridge is a bargain… until you realise it’s billed as “technically” a penthouse.

Although it’s the only apartment on the top floor of the building opposite posh department store Harrods, you won’t be getting much space for your money.

The bedroom is big enough for a double bed (Hunters)

In fact, this ‘micro-penthouse’ offers just 12 square metres of room – that’s about 135sq ft.

Princes Court is located on the north side of Brompton Road and, according to estate agents Hunters, the apartment has been designed by specialist “space saving” Portuguese architects, Caiano Morgado.

A snug kitchen adjoins the living room (Hunters)

It has been “expertly arranged to provide such flexible accommodation” to include space for an office/study, dining area, sitting area, kitchen and a “luxurious shower room”.

Hunters further boast the apartment has ample storage – including a dedicated shoe cupboard – and a double bedroom.

Hunters add: “Literally defying the space limitations… (it) has been provided in a stylish design and quality which is both comfortable and practical and pleasing on the eye.”

The 10th floor micro-penthouse is directly opposite Harrods (Hunters)

The 10th floor flat was originally bought for £200,000 in 2012, and was converted over two years before being rented out for £380 a week. The lift, by the way, goes only has high as the ninth floor.
