Where we are

19 Lansdowne Walk
London W11 3AH

The Cosmic House is in Holland Park, an area long associated with architects and artists. It has a rich legacy of radical houses, including the homes of Sir Frederick Leighton, William Burges, Linley Sambourne and others designed by Arts and Crafts architects Richard Norman Shaw and Phillip Webb.


The house is a five-minute walk from Holland Park Underground Station on the Central Line.


Buses 31, 94, 148 and 248 stop near the house.


There are no bike stands at the house, but there is bike parking at the Holland Park Underground Station.


The Cosmic House is in the Congestion Charging zone and there are some limited parking spaces with parking meters nearby.


We welcome visitors with disabilities but there are stairs both at the entrances and throughout the house so not every part of the interior will be accessible to all. Regretfully, due to layout, the house is inaccessible for wheelchairs. Please let us know about any special requirements in advance and we’ll try to make your visit as enjoyable as possible.
