Welcome to the Co-op Farm Building Plans Collection. Farm structures are purposefully built and used to store or work on machinery, keep animals or operate the business. Like any investment, it pays to get the job done right. It also pays to get a building that accommodates your operation and provides room for you to grow. Co-op is working with CADvantage Design, which uses its knowledge and experience to create innovative and practical designs. Co-op Home and Agro Centres can help you modify one of our existing plans below, finalize construction drawings and put the right materials package together.
