The Model Farm was the home farm of the Coleshill Estate.

It was completed in 1854 at a time of agricultural prosperity and innovation. It was created to make use of the latest agricultural practices and technologies, both in building design and livestock management. Today, the Model Farm remains well preserved.

The Model Farm was designed by George Lamb to capitalise on the work of the agricultural improvers of the 18th and 19th centuries.

Its layout was innovative yet practical and the design was notable for the use of sloping and split level sites. The farm buildings were designed for a mixed farming system, including grain, root crops and various livestock enterprises.

Cattle, sheep and pigs, in which the Earl of Radnor took special interest, were bred, fattened and over wintered in the buildings. Stock feed and manure was distributed around the farm along tramways that made use of the gradients.

The farm was mainly horse-powered although steam-power was used in the granary and mixing room.
