Home Addition FAQs

Is it better to add onto my home or move?

If you like your location and your existing home can support an addition, adding space may let you stay where you are while solving the layout or space problems you have now. The right choice depends on your home, lot, budget, and long-term plans.

Worthington’s design-build team coordinates the project from design through construction, including planning, selections, permits, scheduling, and communication throughout the build.

The cost of a home addition depends on the size, structure, finishes, mechanical systems, and how the new space connects to the existing home. Worthington develops project-specific pricing after evaluating the home and defining the scope of work.

The design considers the home’s architecture, roofline, materials, windows, interior transitions, and structural requirements so the new space connects naturally with the existing home.

Planning a Home Addition in Indianapolis

A successful home addition has to work with the existing structure, roofline, utilities, and flow of the home.
Worthington’s design-build team plans those details early so the new space feels like a natural extension of the house, whether it is a second story, primary suite, sunroom, guest space, or expanded living area.
