Adding an addition or extension to your home comes with substantial benefits:

  • Avoid the stress and cost of moving.
  • Accommodate a growing family in the neighborhood you love.
  • Improve a distressed property that has “good bones.”
  • Upgrade the entire house at once for a cohesive look.
  • Add a new room or use unfinished spaces to increase your home’s square footage and property value.
  • Create a more accessible space that allows you to age in place. This may include the addition of an elevator. ​
  • Enjoy all four seasons with a sunroom addition or conservatory.
