Furniture and Appliances by Owner - Not In Contract Vicinity Map Estes Park, Colorado Not to Scale north Project Site 1047 Morgan St Morgan St 36 LAKE ESTES Project Narrative The existing house is approximately 30 years old. A secondary RV garage was added to the house approximately 20 years ago. This proposed project expands the RV garage 6'-0" to the east and 2'-0" to the north to more easily accommodate the Owner's equipment. The existing roof, south wall, east wall and a portion of the north wall of the RV Garage will be demolished - except the east wall construction and window will be retained for reuse in the new construction. The General Contractor shall take care to safely maintain the electrical service with is overhead above the RV garage and paneled on the remaining portion of the north wall. The conventional concrete foundation and slab-on-grade will be expanded as illustrated. A new portal frame will be constructed around the garage door opening to the south. The existing east wall construction and window will be reinstalled. ½" OSB Sheathing will be added to the interior faces of both the east and west walls for lateral resistance. Vertical microlam beams will be added to the interior west wall to mitigate a structural hinge condition (existing) where the high walls of the RV garage was built on top of the then existing lower walls of the conventional 2-car garage. The north wall will be rebuilt including a new man-door. The roof will be rebuilt using pre-engineered 2x wood trusses with ⅝" OSB sheathing installed across the bottom of the trusses. New finishes and colors will match existing. The RV garage is and will remain unconditioned space. The roof is to be minimally insulated as shown.
