RSHP designed the original building, and have been reappointed for the next phase of the building’s life.

There is opportunity to make enhancements in terms of sustainability, public spaces and urban greening, while bringing the building into an appropriate use.


The existing building is Marks & Spencer's London HQ with a lease commitment to 2028


A ground floor that is disconnected from the public realm and canal


A building that does not meet Brockton’s sustainability aspirations


Emerging context of approved schemes and Imperial College NHS Trust’s ambitions

The Location

Waterside House is located in Paddington Basin, offering a canal-side mixed commercial and retail environment, with St Mary’s Hospital opposite. Paddington has undergone significant change, over the last twenty years, and there is an opportunity to sensitively upgrade the building for modern requirements.

The Area

Paddington is strategically placed for the development of a Life Science Hub within London, with excellent connectivity to other Life Science Clusters in London, Oxford and Cambridge.

Existing Public Spaces

The existing open space sits 1.7m below the wider public realm, and the main entrance rises up from North Wharf Road to Upper Ground Floor level. These existing split level changes result in a failure to maximise the benefits of the canalside location.

Our proposals present an opportunity to upgrade the public spaces and create a welcoming space at the heart of the Paddington Basin.
