“Highly recommend. Larry, Cade, and David are great to work with, honest and fair people willing to go the extra mile for clients.”

Delaney Harris

“McGee Construction has completed multiple large scale home renovation projects for me and my clients recently and have done an amazing job. These were complex renovations and they provided top-level expertise in all project scope areas and very high quality work. Larry McGee is very responsive to my client's needs and as a Designer, I only want to work with responsive contractors like McGee Construction, who care about their clients, and who are committed to doing the job right. I look forward to working with them again on my next project and highly recommend them to others!”

What is a home addition

Add space without leaving the home you love

A home addition gives you more room without moving. It works for homeowners who feel cramped or need better layout. We build new space that fits your home and your life. You stay in your neighborhood while gaining comfort, function, and long-term property value.

  • More usable space
    Add bedrooms, living areas, or a second story. Get the space your home is missing so daily life feels easier and less crowded for your family.
  • Fits your home
    We design additions to match your existing home. The new space blends in, so it looks and feels like it was always part of the original build.
  • Clear cost upfront
    You get real pricing early, not vague estimates. This helps you plan with confidence and avoid budget surprises or scope creep during construction.

What’s Included

What You Get With Your Home Addition

A home addition is more than extra space. You get full planning, structural work, and clean integration with your home. We handle permits, follow local rules, and keep pricing clear. From start to finish, every step is managed so your project stays on track.

  • Structural integration
    Your new space is tied into your existing home the right way. We plan framing, load paths, and connections so everything is safe, stable, and built to last.
  • Foundation work
    We build the right foundation for your addition. This includes excavation, footings, and slabs that match your home and meet local soil and building requirements.
  • Roofing
    Your new roof is designed to match and protect. We tie into your current structure, manage drainage, and make sure the finished look feels consistent and complete.
  • Architecture blending
    We make the new space look like it was always there. Exterior lines, finishes, and layout are matched so the addition fits your home without awkward transitions.
  • Permits and zoning
    We handle city rules, zoning limits, and permits. This removes a major headache and helps avoid delays, rework, or costly mistakes during construction.
  • Clear pricing scope
    You get clear pricing and defined scope before work starts. This helps prevent surprises, keeps decisions focused, and reduces the risk of budget creep mid-project.
