DeKalb, Illinois Barn Restoration & Addition

This 1880s hay barn had severe sill damage, as well as damaged girts where the lean-to addition joined the original barn. Additionally, the lean-to addition, which was a poorly constructed stick-built addition, was on the brink of collapse. After the owners tore down the existing lean-to, TD lifted most of the barn, removed and replaced damaged sills with new white oak sills, and selectively replaced damaged posts and girts. In addition, two sides of the rubble stone foundation were relaid and tuckpointed. Wanting to use the lean-to space for a horse barn, the owners elected to have TD design and build a timber-frame lean-to to the dimensions of the original lean-to. Square rule joinery was used to match the existing timber frame, and southern yellow pine was a near match to the original pine.
