Instead of leaving all you love, simply expand your home to meet  your needs.


Home additions

Hiring Whelan Builders for your home addition means you are hiring a team whose attention to detail is second to none. Our skilled craftsmen can match the design aesthetic and detail of your house, for a flawless natural extension of your home, while also incorporating the latest and best ideas in home upgrades.

We have experience designing and building first and second floor home additions, sunrooms, three-season rooms and screened in porches, as well as stand-alone casitas and in-law suites. Additions are also very popular for expanding kitchens and mudrooms, especially in older homes. We love to incorporate solutions for the homeowner’s needs, and design with technology in mind. For example, mudrooms typically need storage for coats, backpacks and shoes, but we can also build an area for storing and charging Chromebooks and other electronics.

While building an addition can feel like a big undertaking, our team walks you through the process from start to finish, to ensure that you love the end result. And we are dedicated to leaving a clean workspace at the end of each day, which helps ease some of the challenge of living with construction in your home. Whether working with our architect or one that you choose, we deliver a finished product that will not disappoint.

Adding extra space to your home is a great way to add value whether it’s adding another bedroom, a sunroom, a home office, or something else. We’d love to talk to you about your home addition project, call us today to get the conversation started at 630.356.4441.
