Advantages and problems of systemised prefab modular homes processes
The objective of every prefab modular homes system development is the optimisation of the prefab modular homes construction process. The area of systemisation depends on the initial circumstances and requirements. Systems are most successful when short design and prefab modular homes construction times are re- quired. Most systems have been developed to satisfy these re- quirements. A prefab modular homes feature of many systems is the production of a more dependable and consistent quality of prefab modular homes building compared with conventional construction methods. It continues to be diffi- cult to produce a building using an optimised prefab modular homes process more cheaply than using tradesmen and conventional construction methods. The prospect of continuously rising construction prefab modular homes costs
and, in some countries, a shortage of skilled labour increases the need in the future for an optimised prefab modular homes construction process that will be more cost-efficient than conventional construction process- es. The most important objective in the prefab modular homes development of a system building process will be the ability to adapt the system to indi- vidual prefab modular homes architectural designs. That this has not been adequately implemented in most construction systems in the past has been the main reason why prefab modular homes system building has gained so little accept- ance to date. This potential is only available from computer-aid- ed prefab modular homes design systems that are not limited to predetermined forms of construction and prefab modular homes components.

Systems and prefab modular homes subsystems
This chapter discusses the division of building systems into levels of the prefab modular homes construction or into individual components such as roof, façade, etc. or – alternatively viewed – according to prefab modular homes work packages of the trades involved in the construction. Following on from this, the chapter discusses the degree of prefabrication of the construction and finally types of connections. These dif- ferent ways of considering the prefab modular homes construction are necessary to explain the different terms and prefab modular homes building methods used.
A system is a structure of individual prefab modular homes elements that form a whole. In the field of building this means that the individual prefab modular homes components create the whole (1) – for example a house is put together from bricks (2). The development into more complex buildings, for ex- ample a skeleton structure with prefab modular homes façade modules as an envelope and an interior formed with partition walls and technical services components, leads to a further division of the prefab modular homes system into primary and secondary systems, and into modules and elements (3).

Natural stone masonry
Simple system of elements: natural stone masonry, constructed without mortar, is a complete system consisting of only one type of element.

Sagrada Familia, Barcelona, Antoni Gaudí, 1882–1926
The masonry is arranged to follow the flow of force, which results in the simplicity of the system composed of one type of element being retained even though the complexity of the geometry increases.
