We have designed a 12×16 run in shed that uses a wood rail as the foundation. This is a great style of run in shed if you are ever planning on moving the shed or do not need it to be permanent. Some areas do not require a building permit if the shed does not have a foundation. This shed is built using an updated version of the standard post and beam construction. It uses LVL lumber beams and beam holders on top of the 4s4 posts to increase the strength and simplify construction. Visit our website to view this and other run in sheds or horse barns and maybe even purchase one so you can give your horses a new home!
