Houses developed with earth tend to be naturally cool in the summertime heat and warm in winter. Clay holds heat or cold, releasing it over a time period like stone - building supplies. Earthen walls change temperature gradually, so synthetically raising or reducing the temperature can use more resources than in say a wood constructed home, however the heat/coolness remains longer.
Structural mud bricks are generally used clay, typically clay soil and a binder are the only ingredients utilized, but other components can consist of sand, lime, concrete, stone and other binders. The formed or compressed block is then air dried and can be laid dry or with a mortar or clay slip.
Sand is also utilized as a part of the concrete mix. An important low-cost structure material in countries with high sand material soils is the Sandcrete block, which is weaker but more affordable than fired clay bricks. Stone or rock [modify] Rock structures have actually existed for as long as history can remember.
There are lots of types of rock, with differing qualities that make them much better or worse for particular uses. Rock is a really thick product so it offers a lot of protection; its main drawback as a structure product is its weight and the difficulty of working it.

Many African tribes have lived in houses made totally of lawns and sand year-round. In Europe, thatch roofs on homes were when prevalent however the material fell out of favor as industrialization and enhanced transport increased the availability of other products. Today, though, the practice is undergoing a revival. In the Netherlands, for example, lots of new buildings have thatched roofing systems with unique ridge tiles on top.
Today, crafted wood is ending up being very common in industrialized nations. Wood is an item of trees, and in some cases other fibrous plants, used for building functions when cut or pushed into lumber and wood, such as boards, planks and comparable products - skylights. It is a generic structure product and is used in building practically any type of structure in a lot of climates.
This means particular types are better matched for numerous usages than others. "Lumber" is the term used for construction purposes other than the term "lumber" is used in the United States.
The main issues with wood structures are fire risk and moisture-related problems.  In contemporary times softwood is used as a lower-value bulk product, whereas hardwood is usually utilized for finishings and furniture - building supplies. Historically wood frame structures were developed with oak in western Europe, recently douglas fir has ended up being the most popular wood for the majority of types of structural building.
