Volumetric systems

Unlike panel systems, volumetric systems consist of a room or whole floors being factory made, and craned into position on site - often with one unit sitting on top of another. The use of materials can be similar to some forms of panel construction, in that the carcass is often made from lightweight steel, which is fitted together and then insulated and lined internally. The services are prefitted, and connected on site to risers or other service provisions.

Volumetric forms have been popular in student accommodation projects, hotels and some fast food outlets. Sometimes referred to as pods, they can be integrated into traditional forms of construction. The external facade can also be constructed on site to suit planning conditions. Some manufacturers even fit out the internal space, complete with carpet, wall coverings and fixed beds and desks.

One feature of volumetric systems is the thickness of floors and walls. Each unit has its own, so consequently the floor depth and wall thickness are likely to be greater than those in traditional construction. The walls are also likely to be load bearing.
