The Centre for Plant Health features one of the oldest buildings on the border to North Saanich.  Building 28, also known as the Machine Shop and the Former Cattle Barn, is a modest two-storey structure located in the operational component area of the Saanichton Centre for Plant Health. As the oldest existing structure of the Dominion Experimental Station (later the Saanichton Centre for Plant Health), the Machine Shop is associated with the expansion of the Experimental Farm System which responded to the agricultural impacts of various soil and climate conditions found across the country. Although the research at the Saanichton station focussed on the local concerns of small fruit and vegetable farms, and later with the development of flower seeds and bulbs, it originally included a small dairy operation.
