DESIGN & CONSTRUCTION
Extensive public consultations Extensive public consultations were carried out with all immediate neighbours, particularly the Paramount Court Residents Association and Charlotte Street Association, local resident groups, London Borough of Camden councillors, Westminster Council, and the Greater London Authority. A Planning submission was made in December 2013, and granted in Spring 2014. Despite the impact of COVID-19, the project was delivered in February 2021. The old UCLH Rosenheim building (along Huntley St.) was not fit for purpose, and was demolished as part of the overall redevelopment. Its functions had already been transferred to the new Macmillan Cancer Centre next door. The existing UCLH tunnel system is utilised for transferring patients, staff, and FM, between UCLH buildings. In order to create the necessary clinical
space, while respecting the Mayor of London’s View Corridor height limits and surrounding heritage, the building consists of seven storeys above ground, and four storeys plus a mezzanine below ground. Construction of the building, which is 57 m high in total, included excavation to a maximum depth of 28.5 m, with occupied buildings on the same urban block and near an underground line making it one of the most complex building projects to

Using electric fields, the cyclotron can accelerate the hydrogen protons to two-thirds the speed of light

be undertaken recently in the UK.
Essentially a concrete structure The building is essentially a concrete structure throughout the main blocks and basement. The main structural grid is 9 m, with typical floor-to-floor heights on upper floors of 4080 mm, providing resilience and flexibility in terms of a future change of use. There is also provision for all major equipment replacement and removal designed into the structure, including that in the Basement area. This building’s section is particularly
complex, so as to overcome the structural and servicing challenges for the very large- scale PBT gantries, which are positioned beneath a double-height plantroom sitting beneath an eight-theatre day surgery facility, which is itself beneath a seven-storey hospital, split into two blocks and connected via the atrium. The key challenges in designing the Proton Beam Therapy Centre were the size and weight of equipment, radiation shielding requirements, and the installation of the equipment itself. The system comprises of a Cyclotron (a particle accelerator)
