A1 Title Sheet and Site Plan A2 Crawlspace Improvements A3 South Deck Roof A4 Details Sheet Index Project Narrative The existing house was built in 1969. There are two scopes of work for this project. The first is new and replacement elements in the crawlspace to improve structural bearing, reduce deflection and seasonal cracks in the house above. The second scope is the addition of a roof over a portion of the existing south deck. The addition does not increase building height and only slightly increases the horizontal extent of the house to the south. The foundation for new roof posts are upsized to accommodate future possible expansion of the house's conditioned space. This work does not affect the existing house's egress or thermal envelope. An existing exterior light fixture near the door is to be replaced and relocated to provide ambient up lighting into the new roof structure. All direct artificial light is to be captured by the new roof structure. As an alternate, the GC will provide pricing to the Owner to replace the concrete piers shown supporting the new roof posts with rectangular concrete foundations and footings with stone cap and veneer.
