Two-bedroom flat comes with narrow door in garden leading to underground bunker

A flat in Clerkenwell, London, on the market for £800,000 comes with a door in the garden leading to an underground bunker built in the 1930s, which could provide the perfect space for a home office

A two-bedroom flat on the market in London comes with its own incredible underground bunker – accessed through a small, unassuming door in the garden.

The unique property is located in the iconic Art Deco “Lab Building” development on Rosebery Avenue in Clerkenwell, and has an asking price of £800,000.

It boasts high ceilings, bright rooms and a patio terrace – but it’s what lies behind a narrow lilac door in the garden that may be the flat’s best selling feature.

Stairs lead down under the soil to a huge 1,610 square foot bunker, featuring blast-proof doors, heating, lighting and a ventilation system, meaning it could be easily converted into a useable space.

The property forms part of the ‘New River Head’ development, which was built between 1936 and 1938, and was once the headquarters for the Metropolitan Water Board.

In the 1990s it was converted into flats but the building has maintained many of its original features, including the once-used underground bunker.

It’s for up for sale with Unique Estates Property Services, with the bunker described as “an amazing space”, ideal to adapt into anything the buyer desires.

The description 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 Laboratory Building still retains much of its 1930’s 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. Fully private and sole use throughout.”
