Boulder Historic Places Plan

Walls Framing The original structure and additions are constructed of wood framed stud walls. Only the framing of the original structure was visible, seen from the attic to be 2’’ x 4” studs spaced at 24”on center. There is now a cripple wall in the attic space above the location in the kitchen where the original exterior wall was removed when the first addition was constructed. A supporting element beneath this cripple wall was not visible at the time of the observation visit. The stud walls are in good condition; however, the rear wall sheathing appears to be suffering from moisture related decay where the gutter is missing. It is not known if the concealed stud framing beyond is deteriorating, although it is likely given the level of decay of the siding. In the kitchen, it is unclear what is supporting the attic cripple wall at the location of the removed original south wall of the farmhouse. This wall takes a significant load from both the main hip roof and the shed roof of the first addition, so it is important that it is adequately supported. Lateral force resisting system (LFRS) The LFRS of the farmhouse consists of the wood stud walls sheathed with exterior siding, as well as the wood roof sheathing and framing. The existing LFRS is in good condition. It has performed well over the lifetime of the structure; however, it likely does not meet current Code requirements. If a change in use is suggested, Code required upgrades may be triggered. Other Structural Features The farmhouse has a brick masonry capped chimney in the center of the original space that now terminates in the attic at the ridge of the hip roof. The remains of the chimney are in good condition. The front porch is supported by a row of four columns. One of the porch columns has become dislodged and is not supporting the north edge of the porch roof. All of the columns are rotting at their bases where in contact with the concrete porch.
