To transform a 1,094-square-foot ranch-style single-story home into a two-story Mission style home of approximately 3,000 square feet (under roof), numerous challenges were overcome. The main challenge was utilizing the relatively small existing footprint while maintaining the scale and proportions for the new addition in relation to the existing spaces for continuity. A rear existing bedroom was opened up into a family room and approximately 200 square feet was added adjacent for stairs to the second story without consuming space from the existing footprint. Keeping the ceiling height for the second story at 9 feet kept the overall home height in check, and existing fenestrations on the front elevation and elevated front porch assisted in the exterior proportional element with the second-floor addition. Overall, the project scope added a master suite and two additional bedrooms as well as a remodel to the kitchen and update to existing spaces, including converting a rear bedroom into the family room. R-30 spray foam insulation in the roof and R-20 in the walls were installed throughout the home. Insulated – Low-E impact resistant vinyl windows and sliding Glass Door units are installed. A Trane XR energy efficient 15 seer HVAC system was installed to replace the older HVAC unit. A tank less gas water heater was installed to replace the existing 50 gallon electric water heater.
