For such a small project, Mark Richardson and Studiobird really pack a punch with their security “Hydronaut” at Monash University’s Caulfield campus. Addressing “security challenges” the demountable structure takes up five parking bays to house security staff and gives them a perfect position to watch out for trouble brewing. With a brief including semi-permanence and waste minimisation, the tent-like modules are ingeniously handmade from waste PVC truck side-curtains stretched over frames made from exercise trampolines, old steel storage racks and reused stud framing. Inside, reject perforated-ply acoustic panels line the walls punctuated with the trampoline-shaped peepholes. Watch yourself.
