Popular Types of Home Additions in Cary
As a fully licensed and experienced contractor, we handle every part of the home addition process from permitting and design to engineering and construction. We’ve worked with homeowners across Cary to build additions that feel like a natural extension of their existing homes while adding function and value.
Second Story Additions
If you're looking to increase your space without changing your home's footprint, a second-story addition is a smart option. It’s perfect for adding extra bedrooms, bathrooms, or even a private guest suite while significantly boosting your home’s resale value.
Room Over the Garage
An existing garage offers a great opportunity to expand. We can build out a finished room above it, perfect for a home office, entertainment room, guest space, or even a rental unit. Since the foundation is already in place, it’s one of the most cost-effective ways to add livable square footage.

Some Common Questions We Receive
How much does a Home Addition cost in Cary, NC?
While the cost of a home addition typically ranges from $50,000 to $150,000, several factors can influence the final price. Here are key elements that impact the cost: Size of the Addition: Larger additions require more materials and labor, increasing the overall cost. Quality of Materials: The choice of materials, such as flooring, windows, and finishes, significantly affects the price. High-end materials cost more but offer superior aesthetics and durability. Extent of Renovation: Comprehensive additions involving changes to the layout, plumbing, and electrical systems will be more expensive than simpler expansions. Custom Features: Adding custom features like built-in cabinetry, high-end lighting, or unique architectural details can increase the cost.
How long does a Home Addition take?
A home addition typically takes anywhere from 8 to 12 weeks, depending on the complexity of the project and availability of materials. Larger or more complex remodels can take longer. The important thing to keep in mind is that the hours and days spent planning = weeks saved in the build phase.
Do I need a permit for a Home Addition in Cary, NC?

At Red's Remodeling, we handle the entire permitting process for you. Our team will ensure all necessary permits are obtained and that your project complies with local regulations, so you can have peace of mind and focus on enjoying your new home addition.
Is it cheaper to build an Addition or buy a new home?
Generally, building an addition is more affordable, but the cost of building an addition versus buying a new home depends on several factors, including the size and scope of the addition, current housing market conditions, and location. Outside of cost, there are other factors to think about. Do you love your neighborhood, the schools, location, etc. If so, you many not be eager to move.
