What do you do when you love your home, and the neighborhood it’s in but you just wish you had more space? That’s the principal motivation of undertaking a room addition remodeling project.
Every room addition project is unique, so it’s impossible to know an exact cost before planning your design and construction details. But the Remodeling Cost vs. Value Report (www.costvsvalue.com) is the best place to get a ballpark figure of potential cost. This is a trusted source for realistic pricing that helps adjust expectations and plan budgets.
Since 2002, the Remodeling Cost vs. Value Report has been compiling nation-wide renovation data provided by professional and experienced remodeling contractors. We at Mosby Building Arts confidently share this information with homeowners seeking ballpark figures. The report provides a realistic starting point for a conversation about your project.
Here we share with you the Remodeling 2016 Cost vs. Value Report descriptions and average costs of several types of room addition projects in the Metro St. Louis area.
