Creating the space you need

It all starts with a complimentary in-home consultation and estimate where our designers can develop a comprehensive plan to create the type of home addition you desire, while seamlessly blending it with the rest of your property.

The Kuhn Home Additions team in Islip NY is proud to be part of a design/build firm that has been providing high-quality Home Additions in Islip NY since 1986. We can even help you identify best possible solutions, with options including:

  • Second floors: Adding a second floor is among the most popular choices. This doubles the living area and often provides growing families with the additional bedrooms and bathrooms they need.
  • First floor expansions: Expanding the main floor of your home is a great way to do this, and the experts at Kuhn Home Additions can ensure that you have a seamless transition between old and new.
  • In-law apartment: If you have a parent or in-law moving in or a grown child returning home, an addition is the perfect solution. We can create the perfect attached apartment for your needs, complete with a separate entrance, kitchen, and bathroom.
  • Bonus rooms: Adding a bonus room over the garage or converting the garage space is a great option for creating a new living room or play area for the kids or an extra space to entertain friends and family.
  • Master bath/bedroom suite: A master bath/bedroom suite is a fantastic add-on to a home. Home Additions that bring bathrooms in line with bedrooms will provide a good return on your investment. With this type of addition, there’s unlimited potential. From a stand-up shower, to a large stand-alone tub and walk-in closets, a master bath/bedroom adds more space, privacy, and value to your home.
  • Sunroom additions: Enjoy the warmth of the sun, every season of the year, from the comfort of your home. A sunroom addition will light up your home and is usually built in the back of the house, facing the sun, absorbing the most warmth and light. These sunrooms almost never include a kitchen or bathroom, making this type of add-on different from a conventional addition. With a sunroom home addition by Kuhn Construction, we can build the space with beautiful, over-sized glass and then you can sit back, relax, and enjoy the views of the outdoors all year.
