The £800k apartment which is up for sale with its own massive underground bunker

As any estate agent will tell you, there's a checklist of all the things buyers look out for whilst house hunting.

Spacious living room, big kitchen, nice garden for the kids to play in - all qualities that make a property more desirable to anyone looking for a new home.

Something which rarely makes that list of desirables though is ' private underground bunker ', but that's exactly what's being offered by one apartment currently on the market.

The two-bed flat, which has recently been advertised on Zoopla with a £800,000 price tag, boasts a subterranean space that's been "fully refurbished as a usable space with its own ventilation system, heating and lighting, possibly good for a home office, gym, music room or a safehouse."

With access via the garden, it even has its own heavy-duty blast-proof metal doors.

Located in Clerkenwell in London, the property is part of an amazing looking Art Deco building which formerly belonged to the Metropolitan Water Board.

The estate agent blurb reads: "This apartment offers the occupier a different style of residence from normal flats with high ceilings throughout - a bright living space which includes an open plan kitchen with built-in appliances and two double bedrooms with good storage and a delightful patio terrace.

"There is also a separate underground bunker that has a very spacious fully refurbished space which could ideally be used as an office or a music room, gym or just storage; an amazing space.

The Art Deco building's exterior is stunning (Unique Estates)

"The building still retains much of its 1930s style with original hallways, a large beautifully maintained communal rose garden and daytime concierge.

"The bunker has a ventilation system and heaters, it also has lights throughout (lower lighting, walls and ceiling) with separate switches for different sections."

"It's fully private and (the buyer will have) sole use throughout."
