Home Additions

Besides providing a home with more living space, home additions can be a terrific investment. You'll want to keep some things in mind as you consider a home additon project:

  • What is the home market values in the neighborhood
  • The cost of the project
  • Creating architectural plans
  • Is financing available or needed
  • What should be the timetable for completion
  • What sweat equity are you willing to invest in the project
  • How much distruption are you willing to endure

building a home additionWhile it can be a challange, creating an addition on your house has a number of advantages. Your family will enjoy the extra room and you'll love the potential increase in home value! Better yet, an home addition will allow you to add amenities that you may be missing. Want a walk in closet or pantry? A larger stove? A media room or library? Or maybe you'd just like to site outside and enjoy warm Wisconsin evenings. Anything is possible with a house addition!
