A complex development involving both new build and refurbishment of an existing Grade II listed building needed HUSH’s expert knowledge and management to balance the varied aspects of the project. ​

The development is comprised of 113,000 sq.ft. of net office space, 47 apartments providing both private and affordable housing accommodation, museum and retail space. ​​The construction project, taking place at the location of the historically significant Elizabeth Garrett Anderson Women’s Hospital, involved preserving and integrating the existing structures. These structures are carefully organised alongside a nine-story tower covered in stone cladding, all centred around a magnificent atrium topped with a glass roof.​

The Elizabeth Garret Anderson Gallery features the original restored 1890 Entrance Hall and a fireplace designed by Garret’s sister. The gallery includes a variety of media, such as interactive displays and projections, bringing to life the work of Garret’s hospital.​

The sustainability of the project was at the forefront of the client’s values, with initiatives including: ​
Future connection to the local community heating and power network within the borough​
BREEAM Excellent​
Carbon emissions lowered by 53% (GLA target 20%)​
20% of energy required within the building serviced from renewable sources
