Add to the existing house enough volume for a large master suite with private bathroom, a guest room , a laundry room and an office. Blend the addition with the exterior
Report of the technologist
Even though the surface area of the existing building is quite large , the addition of a story is proposed to provide all the required spaces and not to encroach on the land. The new sheathing used for the addition will also be used on the ground level to blend all the levels harmoniously.
