Just completed most of the framing for a master suite (single story ranch addition). Also, part of the addition is a 12'x16' office space that has an unconditioned room on each side that will be used as "attic" storage, although this is technically not an attic. It will be unheated and un-insulated. I live in the Seacoast area of New Hampshire and I am trying to figure out what is required by code. I would like to purchase and install solid pine six panel doors that I will weather strip. I do not want to install "exterior doors" for cost and to avoid the look of having an exterior door in an interior location (office space). Does anyone know if this solution will meet code?
