A roundhouse is a type of house with a circular plan, usually with a conical roof. In the later part of the 20th century, modern designs of roundhouse eco-buildings were constructed with materials such as cob, cordwood or straw bale walls and reciprocal frame green roofs.

Bronze Age Britain is an era of British history that spanned from c. 2500–2000 BC until c. 800 BC. Lasting for approximately 1,700 years, it was preceded by the era of Neolithic Britain and was in turn followed by the period of Iron Age Britain. Being categorised as the Bronze Age, it was marked by the use of copper and then bronze by the prehistoric Britons, who used such metals to fashion tools. Great Britain in the Bronze Age also saw the widespread adoption of agriculture.
