Professional Home Additions and Expansions

As your family grows or your lifestyle changes, you may find that your current home no longer fits your needs. Rather than facing the stress and expense of moving, consider a custom home addition from Cornelius Construction.

Multi-Room Extensions

Whether you need to add a new wing for a master suite, a larger kitchen, or a dedicated home office, we handle the structural complexities of expanding your foundation and roofline. We manage the entire process, from breaking ground to the final coat of paint.

Second Story Additions

If your lot size limits your ability to build out, we can build up. Second-story additions are a fantastic way to double your living space without losing your backyard. We have the engineering expertise to assess your current structure and reinforce it to support a new level, ensuring safety and stability.

Garage and In-Law Suites

We frequently build attached and detached garage additions, often including living space above for in-laws or guests. These "Accessory Dwelling Units" (ADUs) are becoming increasingly popular in Western New York for their versatility and property value benefits.

Increasing Your Home Value


 A well-executed addition is one of the best investments you can make in your property. It increases your square footage and functional living space, which are top drivers of resale value. At Cornelius Construction Co., we build additions that are durable, code-compliant, and beautiful. Don't settle for a cramped home; let us help you expand your horizons right where you are.
