Warringah Timbers is a family run business that began operating as a small timber retailer in 1973 from Brookvale, NSW. Originally, Warringah Timbers only dealt in hardwood and Oregon (Douglas fir). In 1979 the company was incorporated and moved to its current location at 9 Inman Road, Dee Why West. As the company expanded, Warringah Timbers purchased the adjacent property to extend the yard. The two properties lie on the border of the suburbs Dee Why and Cromer and straddle a corner - therefore the site can be found listed under the original address on 9 Inman Road, Dee Why or on the adjoining address of 26 Middleton Road, Cromer.
