There’s no shortage of incredible architecture in London. 

From the brutalist Barbican Centre to St Paul’s Cathedral and the Shard, we’ve got so many fantastic buildings, and there are some pretty impressive homes across the capital too.

Usually, we don’t get to peek behind the doors of people’s houses, but one of the ‘most extraordinary’ in the city is inviting the public in this April.

Known as The Cosmic House, the private Grade I listed house, turned museum, is only open during certain times of the year, and it gets booked up quickly.

The Architectural Library is entered from the Solar Stair. Here you can see the radial structure of the library roof expressed as sun rays. Cut outs around the stair resemble a surprised face, with a pealing back of the layers of construction, a Post-Modern play on the Modernist desire of truth to materials. Picture: Sue Barr

Located in West London, on a residential street, The Cosmic House was the home of the late architect, Charles Jencks and writer Maggie Jencks.

It was built between 1978 and 1983 in collaboration with Sir Terry Farrell, and is described as ‘one of the key landmarks in the development of post-modernist architecture’.

From the outside, it might seem like a (somewhat) standard Kensington home; however, the inside is anything but.

Each element of the building is said to be ‘related to the human body and then to the larger cosmos’, according to the house’s website, making it a ‘Gesamtkunstwerk’, which is a German word meaning a ‘total work of art’, or an ‘immersive, synthesised artistic creation’. 

The Cosmic House website adds: ‘It is an architectural essay about our relationship to proportion, building, culture and the universe.’

Inside the house, you’ll find a fireplace designed by Michael Graves in the Winter Room, a jacuzzi designed by Piers Gough, as well as works by Rem Koolhaas, Eduardo Paolozzi and Allen Jones.

It’s intended to provoke discussion about culture, cosmology, science and design.

How to visit The Cosmic House

The house will be open to the public from April 22 until December.

Opening hours run from 12:30 pm until 16:30 pm. 

Tickets to visit cost £16 with a donation, £13 without a donation and £5 for students and can be purchased at thecosmichouse.org/visit

Guests are asked to arrive a few minutes before their visiting time, and can wait in the exterior amphitheatre steps in front of the entrance. 

A few restrictions for visiting are in place – guests must be over the age of 12, no one is allowed to wear high heels due to delicate flooring, and there’s a steep spiral staircase, so some may struggle with this.

Similarly, a user known as @the_monkeypuzzletree said: ‘One of my favourite ever visits to London was to see this house.’

While @kuce_sl said it was ‘so beautiful’, @why_visit thought it was a ‘true hidden gem’, and @thelma_elisa added it was ‘such an interesting place’.

Others branded it ‘amazing’, ‘groovy’, and ‘magical’.
