Add a 4-season sun room to the rear of the house to enjoy the sun year-round plus a view on the garden. Create a terrace on second floor enjoy the sun from the master bedroom. Make sure the enlargement fits the house's spirit with the least exterior maintenance as possible.
Report of the technologist
We notice a rather narrow space for construction. We then suggest a construction on concrete pillasters. We plan an adequate insulation of the floors and walls for a 4-season sun room with radiant floor heating. We maximize the lighting with large windows and a skylight. We use a cedar polymer horizontal siding for easy maintenance and good match with existing siding.
