Room Addition Cost

At $128 per square foot, a 10×20 bedroom addition costs $25,600 on average, while a 20×20 family room ranges from $51,200. When adding a bathroom that requires plumbing, expect to spend from $18,000 to $47,000.

There are many ways to increase your square footage. You can build up by adding a second floor, or you can build out and add a room by adding a section of house that attaches through an opening in an outside wall. You can also convert one kind of room to another kind of room better suited to meet your needs. You can build a detached garage or workshop. All options qualify as a house addition.

When considering a significant room addition, be sure to consult with an architect to draft the design and style you’re looking for. Next, hire a structural engineer to make sure the addition plans are sound before construction. Finally, hire a general contractor who will coordinate all the development and building in the correct order.
