Room Additions

If you own a great home in a great neighborhood but need a more space, Vanderbilt Family Builders can help add space, style and value to your home through a room addition. Room additions are often a very cost effective way to gain space in the home because it is often more expensive per square foot to buy a new home. The most cost efficient addition is to build out into a backyard or side yard. However, if your lot is too small or you don’t want to give up your backyard space, consider adding a second story or converting your attic into usable space.

Room additions can be just as complex as building homes. Designs must be drawn, permits must be secured and the addition must be matched to the current home. By choosing Vanderbilt Family Builders to construct your room addition you will have the advantage of working with an experienced design build contractor that can easily combine the elements of a remodel and custom home into a unique home addition.

If you are thinking adding a space to your home, consider adding one these popular rooms:

  • Home Office
  • Great room
  • Master Suite including Master Bath
  • Mudroom
  • Home spa
  • Home Gym
  • Media Center
  • Game room
  • Children’s playroom or home schooling center
  • Guest suite
