Family Room Addition If you want to increase your square footage and add a room that will never outlive its usefulness, adding a Family Room is a good choice. Its uses can cycle through the changing needs of a growing family. An update is not near as expensive as the bathroom and kitchen. A buyer can envision a diversity of uses -- from a wide screen and pool table to cozy fireplace. They can picture magnificent parties or romantic evenings by the fire. The project model is a 16x25 foot room designed to the style & location appropriate to the existing house on a new crawl space foundation with wood-joist floor framing, wood siding on exterior walls, and fiberglass shingle roof. Also, included is drywall interior with batt insulation, tongue-and-groove hardwood floor, 180 square feet of glazing, including windows, atrium-style exterior doors, and two operable skylights, and tying into existing heating and cooling. The job cost in NC comes in at $39,563 recouping 70% $27,600 after one year. You can reduce the cost of this project by using less expensive flooring & doors. Naturally, if you have a space that already has a foundation and/or walls and roof system, the cost would also be reduced. Costs & the value returned vary from house to house and in different areas even in the same region. So, call your favorite contractor for estimates and call Fran for an opinion on resale value.
