Volumetric modular units are large building elements that can be linked together to form complete buildings without the need for additional superstructure. The internal fit-out, finishes and building services are pre-installed and commissioned in the modules prior to leaving the factory ensuring that defects are minimised and quality control is very high. The external façade, claddings and roof treatments are usually installed onsite. Volumetric units plant rooms or flexible living and working spaces. Applications include commercial offices, public buildings, hotels, airports, sport stadiums, hospitals, universities and schools.
