How Much Does a Room Addition Cost?"},"content":{"rendered":"<p>You love your space, but honestly, you could use a little more space. If you add a home office, an ensuite, or just a few more feet to your kitchen, you could transform your house into a forever home. So, around how much would a room addition cost? According to HomeAdvisor, homeowners spent on average <a href=\"https:\/\/www.homeadvisor.com\/cost\/additions-and-remodels\/build-an-addition\/\">$21,903 to $83,368<\/a> to add onto their homes.
