Building construction is an ancient human activity. It developed with the wholly practical need for a controlled environment to withstand the effects of climate. Constructed shelters were one means by which people were able to adapt themselves to a wide variety of climates and become a global species.
Human shelters were at first very unsophisticated and perhaps lasted only a few days or months. Over time, however, even temporary structures developed into such highly refined forms as the igloo. Over time more stable structures began to arise, particularly after the beginning of farming, when people began to remain in one place for long periods. The first structures, but eventually other functions, such as food storage and ceremony, were placed in different structures. Some structures began to have symbolic as well as functional value, denoting the beginning of the characteristics between architecture and building.
The history of building is recognised by several trends. One is the developing durability of the materials used. Early building materials were flimsy, such as leaves, branches, and animal hides. Later, more durable natural materials—eg clay, stone, and timber—and, finally, synthetic materials—such as brick, concrete, metals, and plastics—are used. Another is the desire for structures of ever greater height and span; this was made possible by the development of stronger materials and by knowledge of how materials act and how to use them to better advantage. A third major trend is the degree of control placed over the interior environment of buildings: increasingly precise regulation of air temperature, light and sound levels, humidity, odours, air speed, and other factors that affect our comfort has been made possible. Yet another trend is the change in energy available to the building process, starting with human muscle power and developing into the powerful machinery used today.
The present state of home construction is complex. There is a large range of building products and systems which are aimed specifically at areas of building types or markets. The design process for buildings is highly organised and uses research establishments that study material properties and performance, code officials who develop and enforce safety standards, and design professionals who determine user requirements and design buildings to meet those needs. The construction process is also highly organised; it includes the manufacturers of building products and systems, the craftsmen who create them on the construction site, the contractors who employ and coordinate the work of the builders, and consultants who have expertise in such areas as construction management, quality control, and insurance.
Building construction today is a significant part of modern culture, a product of its range and complexity and a measure of its mastery of natural forces, which can produce a widely varied built environment to provide for the diverse needs of society. This article first outlines the history of building construction, then portrays its development at the present time.
