Louisville, KY Room Addition Company

Typically, contractors can extend your home 3 feet deep and up to 10-12 feet wide without additional foundation work, increasing square feet with minimal disruption. Whether you’re welcoming a new family member, or you just need more space, home additions can provide the extra privacy and versatility you need.
Adding a room can be one of the biggest and most rewarding projects you’ve ever done in your home. In addition to increasing the market value and usability of your home, additional rooms can add personal and emotional value to your home. Not many homeowners realize this, but adding a room is one of the best investments you can make for your home.

Because a room extension is a large project, there will be a longer process, more steps, and more questions to ask before starting. You may have heard of people building additions to their homes, but you may not know how they did it, or what challenges they faced along the way.


  • Map out and do not interfere with power lines or pipes
  • Have power and water lines marked before any construction
  • Make sure all structural changes are consistent with the frame and foundation of your building
  • Have a solid estimate of the cost of adding a room addition before starting any home improvement work.

Room additions typically cost $300 to $500 per square foot. However, this depends on the structure and foundation of the home as well as levels, etc. As an example, the average cost of converting a garage into a room addition project is about $11,065, and the ROI is as high as 80%

While a room addition can cost anywhere from $90,000 to $200,000, it greatly increases your home’s footprint and resale value. Regardless of the type of extension you choose to build, some costs will be standard. How much an add-on costs depends on your house variables and what you want.

If you don’t want to pay to build an extension, renovating an unfinished part of your home, such as an attic, basement, or attached garage, is a great way to add square footage at a reasonable price. If you’re looking to invest in your home by building a basement or attic, decorating those spaces is one of the most important things you’ll do when it’s time to sell.
