Squaring off against rivals such as No1 Spinningfields, Ordsall Chord, and Mackie Mayor, what makes the facility so special? The challenge facing the judges of the Building of the Year Awards is that the criteria is broad — the building is voted on based on what it gives back to the community, rather than design merits, cost, construction methods, or history.

The winning building may have all or some of these, plus its own distinct value.

Each building on the shortlist this year presented a different positive. At Mackie Mayor, a long-disused historic property was restored and is now an incredibly popular restaurant and bar.

Ordsall Chord is an impressive piece of transport infrastructure which, once fully operational, will be a core link for train routes across not just Manchester city centre, but the North.

In order for the tonne proton beam machines to work and the Therapy Centre has three for treating patients, and a fourth as a test areathey need to be able to rotate around degrees.

That means the building is built around four massive gantry spaces, with walls as thick as six metres in places, which was delivered through 17,m3 of concrete and 1, tonnes of reinforcement by contractor Interserve. Wiring runs through 10 km of pipes, checked for any blockages beforehand using, appropriately, endoscope cameras.

Should the machines ever need to be lifted out, the roof above is air-tight but removable, structured in a way reminiscent of Jenga.

Arup engineered the Proton Beam Therapy Centre and managed detailed Building Information Modelling process Images of the inside of the hospital are scarce due to privacy requirements, however being faced by the central, circular treatment space of the proton beam machine, with its associated corridors and control rooms, is best described as like being on the set of Star Gate.

The sheer amount of detail and engineering required to treat one patient is immense.

Special Reports

A patient is placed on a platform in the centre of the machine, at a subtly-adjusted position and angle calculated beforehand to ensure that the proton beam hits any tumour at a sub-milimetre accuracy. Proton beam therapy is a vast scientific exercise delivering on a medical need.

Essentially at the centre of the machine is a particle accelerator, and a lot of the surrounding structure is focused on radiation protection. The corridors and piping around the treatment rooms twist at 90 degree angles so that any renegade neutrons, travelling only in straight lines, never escape.
