3 Home Addition Projects, 3 Budgets & Scopes

A new home addition is different from a remodel of an existing room in your home. Columbus, OH home additions typically add new square footage and require everything from the floor up. This includes the foundation, walls, ceiling and roof as well as mechanical systems like electrical, plumbing and heating. Because you are adding something instead of changing a space that already exists, costs can vary greatly. Calculating the cost of a home addition requires knowing first the design, scope and size of the project and the type of room you’ll be adding. Will new utilities be required? Maybe not for a sunroom but definitely for a new bathroom. There are also many other variables, including permits, trade prices and material costs.

Our Design-Build Team created the following project profiles to help you begin the discussion for your next home addition project. We also recommend reviewing Remodeling magazine’s annual Cost vs Value report for more information on building and remodeling costs in Columbus OH.
