Out of room but love your neighborhood? You’re not alone. Many of our clients in Holly Springs, Cary, Apex, Raleigh, and Fuquay-Varina want more space,without the hassle of moving. We design and build home additions that feel original to your house: kitchen bump-outs, primary suite and family room additions, sunrooms and screened porches, as well as garage and over-garage builds.
What sets us apart is how we plan. We start with your goals and budget, then look at structure, HVAC/comfort, windows and doors, and how to match your exterior (brick, siding, trim, roof) so the new space blends in. We handle drawings, permits and HOA approvals in Wake, Chatham, and Durham counties and keep you informed from first layout to final walkthrough. With 26+ years in the Triangle, we’re licensed and insured in NC, A+ BBB rated, and active members of the Home Builders Association of Raleigh & Wake County and NKBA.
Common addition types we build
-
- Kitchen bump-outs & open-plan expansions — bigger opening with a properly sized beam, more light, better flow.
- Primary suite & family room additions — smart foundations, roofline tie-ins, and a bath that fits your routine.
- Sunrooms & screened porches — 3-season vs 4-season comfort, glass packages, and insulation that actually works.
- Garages & over-garage bonus rooms — structure, stairs, fire separation, and clean interior finishes.
What drives price and timeline: foundation choice, roof/roofline tie-in, windows/doors package, adding a bathroom, and the HVAC strategy (extend ducts or dedicated system). We’ll walk you through good-better-best options so you can choose where to invest.

Our Home Addition Process
Additions don’t have to be stressful. We listen first, why you need the space, who will use it, and how it should feel. With this information we can plan a build that ties in cleanly with your home. You’ll know the plan, the number, and the schedule before we start. We’re a family-run team with 26+ years in the Triangle; licensed and insured, A+ BBB, and known for clear communication.
1) Listen
We talk about your goals, timing, and a comfortable budget range.
2) Measure & assess
On site, we take precise measurements and photos. We review structure (walls, rooflines), utilities (electric, plumbing, HVAC), and basic zoning/HOA notes.
3) Design options with pricing
You’ll see 1–2 layout choices (kitchen bump-out, family room, primary suite, sunroom/porch) with good / better / best budgets and clear line items.
4) Final plan, engineering & permits
We refine the design, detail how the new work will tie into your existing structure, complete structural engineering, and handle permits/HOA.
5) Order & schedule
We order long-lead items (windows/doors) first, then set a firm start window and share a simple build timeline.
6) Build cleanly
Floors protected, dust controlled, tidy site. One point of contact and regular updates. We match exterior materials and interior finishes so the addition looks original.
7) Walkthrough & support
We finish the punch list, show you how everything works, and provide close-out docs. Our warranty is in writing, and we’re here if you need us later.

Our Home Addition Services Include
There are various types of home additions that we can build for you.
Yes, you will need a building permit for a home addition in Wake County. Permits ensure that construction projects adhere to local building codes, zoning regulations, and safety standards. You can learn more about the permits required for a home addition in Wake County, here: https://www.wake.gov/departments-government/planning-development-inspections/inspections-permits/add-or-alter-my-home
Branch Home Improvement can walk you through the process and submit all of the required paperwork for your permits.
Zoning regulations govern various aspects of construction, including setbacks, building heights, and land use. These can vary from property to property. At Branch Home Improvement we will be able to discuss the specific zoning issues that might affect your home addition project.
The module follows Google guidelines and adds FAQ schema.
The timeline for a home addition depends on factors such as the size and complexity of the project, weather conditions, and our current availability. We can discuss a realistic timeline with you for your particular addition project. A home addition is generally a several week, if not a few months, long project.
Property taxes in Wake County are based on the assessed value of your property. A home addition may increase your property's value and, consequently, your property taxes. You would need to contact the Wake County Revenue Department to discuss how your addition might impact your property taxes.
If your home is in a historic district or is a designated historic property, there may be additional regulations and guidelines to follow when planning a home addition. Consult the Raleigh Historic Development Commission (RHDC) or the relevant local historic preservation organization for guidance.
Financing options for home additions may include personal savings, home equity loans, home equity lines of credit (HELOC), cash-out refinancing, or personal loans. Consult with your financial advisor, bank, or mortgage specialist to determine the best option for your situation.
A home addition will increase the value of your property, which may require updating your homeowner's insurance coverage. You will need to contact your insurance agent to discuss any changes needed to ensure you and your new home addition and it's contents are adequately covered.
Depending on the scope and complexity of your home addition project, it may be possible to continue living in your home during construction. However, you should be prepared for disruptions such as noise, dust, and limited access to certain areas of your home. We can discuss the construction schedule and potential disruptions with you before work begins.
Depending on the complexity of your home addition, you may need to consult with an architect or designer to create detailed plans and ensure your project meets local building codes and regulations. A professional designer can also help you maximize space, create a cohesive design, and ensure the addition complements your existing home.
At Branch Home Improvement we work closely with several local architects and designers based in Wake County, NC and can recommend someone if this is required.
Incorporating energy-efficient features in your home addition can reduce energy consumption and save on utility costs. Consider options such as energy-efficient windows and doors, insulation, heating and cooling systems, appliances, lighting, and solar panels. We can discuss green, energy-efficient options with you.
