When it comes to expanding your home, we are the experts in creating spaces that not only add square footage but also enhance the quality of living. Nothing can breathe new life into your home and your daily routines like a well-constructed home addition. Our home additions are thoughtfully designed to meet the evolving needs of their clients, whether it's for a growing family or adapting to new life stages.

At K. Fedewa Builders Inc., we’ve been helping Greater Lansing residents make the most out of their homes for decades, so we have the knowledge and skills at our fingertips to advise you on a home addition that will change the way you enjoy your house and go about your daily routines.

Whether you need more light, extra space, better accessibility, or are just looking to increase your home’s value, an addition can be the ideal solution. In fact, a well-planned and expertly constructed addition can offer the following benefits:

  • More space for living and storage
  • Extra room for people, whether guests or kids moving back home
  • Rental income potential
  • Additional property value and resale appeal

From a master suite or family room, to kitchens and multi-room additions, we've seen and done it all. A poorly-planned or shoddily-built addition will stick out like a sore thumb visually. Thanks to our exclusive design-build knowledge and experience, we are uniquely positioned to offer you great advice on designing the perfect addition, not only to suit your needs and lifestyle, but also to blend in with the existing architecture and character of your home. As can be seen in our photo gallery, our additions blend seamlessly to look as if they have always been a part of the existing structure.
