In the 1960's the British Pig Industry discovered the benefits of rearing pigs in controlled environment buildings. This complete with genetic improvements to the pig allowed the UK to lead the world in the supply of breeding animals for some years.
Brick and concrete wall construction was replaced by quicker and more cost effective methods.
Mick Warkup, founder and owner of AM Warkup Ltd developed his own system of constructing pig buildings using prefabricated panels which would give building structures a more robust, cost effective, flexible design and enable speed of erection on site.
AM Warkup started trading in 1963 and found instant success building many new pig units in Yorkshire & Lincolnshire. Many of these still survive to this day !
