Spacious Kennebunk Home Additions
Does your coastal home lack functionality, dependability, and style? If so, you’re not the only Kennebunk homeowner facing these frustrating issues.
Fortunately, home additions are the perfect solution to add livable space to the house you love. Additions are popular among empty nesters in Southern Maine, homeowners looking to customize a historic house to fit their modern style, or large families needing extra room.

Home Addition Options

Bump-Out
Typically used for a bedroom or bathroom, a bump-out (or room addition) is a single room structure built onto the side of your house. Bump-outs can also add extra square footage to an existing room, like the kitchen.

Full Addition
Full additions expand both your first and second floor or add a second story to your home. These additions often include living spaces, bathrooms, or bedrooms, and they blend into the rest of your Kennebunk home’s floorplan.
Remodeling
Remodeling converts unusable spaces in your home, like the attic, basement, or garage, into a livable room, like a bedroom, gym, or bowling alley.

Sunrooms and Entertaining Spaces
Sunrooms are attached to the side of your home and act as supplemental living areas or entertaining spaces. Typically, they are smaller than a room addition and can be closed off from the central part of your house.

Room Conversions
Do you have pesky walls between your kitchen, living space, and dining area? A room conversion creates an open floor plan by removing these barriers.
