Popular Home Additions

The most popular home additions include:

  • Outward addition – with an outward addition, you can add a kitchen, bedroom, bathroom, or other room to the front, back, or side of your home.
  • Upward addition (Pop Top) – building up instead of out adds space to your home without costing any space in your yard and avoids the cost of a foundation.
  • Attic conversion – attic remodeling is perfect for turning your attic into a finished additional storage space or an extra living space.
  • Basement finishing – allows you to add an additional story of space to your homes, and is often preferred to an attic conversion because basements are more structurally sound than attics.
