    "hired Mark Brand Architecture to design an extensive remodel for my house in San Francisco. Mark and his staff gave me a lot of help during the remodel, especially when it came to working around or through problems that the old structure of the house posed including working with the project engineers. When I had to temporarily stop the remodel due to health issues, Mark and his team stepped in to make sure the job was kept on schedule.

Expanding your house is a major undertaking. Not only are you altering your existing exterior walls, you are most likely adding new electricity, foundation, and plumbing. Even planning a room addition needs a lot of groundwork before construction begins.

Home addition companies know how to plan, construct, and finish any room and can even add a second story to a single story house. Find local contractors who will work with you to:

  • Make the best use of your existing floor plan and supports.
  • Build the new electrical connections and plumbing to code.
  • Incorporate the existing foundation for better stability and reduced settling.
  • Register the addition with your county according to local regulations.

A reliable home addition contractor can make sure your new addition is safe. They can also ensure the construction goes smoothly from start to finish. Enter your zip code and HomeAdvisor will connect you with prescreened home addition contractors near you.
