Typical costs:
  • RemodelingOnline does an annual survey of average costs for specific home projects. The site lists prices nationwide and by nine US regions; it sells detailed findings for 60 cities. These are average prices so actual costs may be higher or lower.
  • A 6x8-foot bathroom with standard amenities is $25,567-34,311; an upscale 9x9-foot master bath averages $55,453-$68,852.
  • A 10x20-foot sunroom costs about $45,889-$55,813; a 16x25-foot mid-range-quality family room averages $66,840-$88,371; and a 24x15-foot master suite is $84,411-$111,157 for a mid-range project with walk-in closets and a whirlpool tub, jumping to $163,192-$199,312 for a 20x32-foot upscale version with all the bells and whistles.
  • Adding a 16x20-foot composite-material deck runs $13,891-$16,297, while a two-story, 24x16-foot wing with a family room below and a second-floor bedroom with bath is $94,918-$122,085.
  • The more changes a project makes to your existing floor plan, roof line, plumbing or other aspects of your home, the higher the price of the project.
What should be included:
  • A relatively simple addition can be handled by a remodeling contractor but you may need an architect for an extensive project. It might also be necessary to have a heating and air conditioning specialist calculate the increased demand the addition will put on your present system.
  • Early in the design and decision process, ask your local planning department about height restrictions, required lot setbacks or other rules that might shape the design of your project.
  • Even the smallest project has a lot of details to consider and coordinate. There are many step-by-step home addition books available, RemodelOrMove.com sells a workbook organizer or HomeAdditionPlus.com sells detailed construction bid sheets.
Discounts:
  • To save on design costs, TheHouseDesigners.com sells "stock" plans for typical additions to standard home layouts; CADSmith.com offers do-it-yourself designs for the New England region.
