Your Trusted Local Building and Metal Roofing Contractor

Since 1945, Spane has been constructing some of the finest garages, barns, agricultural buildings, homes, commercial structures, and horse arenas, throughout Skagit, Whatcom, Island, Snohomish, King and San Juan counties.


Done right, on time, and on budget.  That is the Spane way, the same process we have been using to build for nearly a century.

If you are familiar with the Skagit Valley construction industry then you have heard of  Spane Buildings, where we’ve perfected the art of constructing post frame and pole barn buildings. For more videos, and images of some of our projects, visit our construction blog, or our post frame videos section.
