Second Floor Home Additions in State College, Huntingdon & Surrounding Towns

Adding a second story is one of the most significant ways to increase your home’s square footage without expanding its footprint. We work with homeowners throughout Central Pennsylvania to plan and build structurally sound second-floor additions, whether over a garage, an existing one-story home, or a portion of the roof.

Our design-build process ensures that your addition matches your home’s architecture while meeting all local building codes. These projects often include:

  • New bedrooms or guest suites

  • Upstairs bathrooms

  • Loft spaces and sitting areas

  • Full second-level additions for growing families

Second-story construction requires careful engineering and attention to detail—and Cisney & O’Donnell delivers on both.

Bathroom and Utility Room Additions for Central PA Homes

Older homes often lack the functional spaces modern families need. That’s why we provide bathroom build-outs and utility room additions to improve livability and convenience.

We serve homeowners in Huntingdon, Port Matilda, and surrounding communities with:

  • Half-bath or full bathroom additions

  • Utility rooms with washer/dryer hookups, cabinetry, and sinks

  • Combination mudroom-laundry rooms near garage or side entrances

  • Basement bathroom installations or conversions

Every build-out is designed to meet plumbing, electrical, and ventilation requirements—and to fit your style and storage goals.

Family Room Additions in Huntingdon and State College

Looking to bring everyone together in one comfortable space? Our family room additions provide the extra square footage you need for entertaining, relaxing, or gathering around the holidays.

  • Entertainment centers and home theaters

  • Game rooms

  • Home libraries or media lounges

  • Open living spaces with lots of natural light

From insulation and structural framing to lighting and trim, we’ll build a family room that enhances your lifestyle and your home’s long-term value.

Kitchen Expansions for Central Pennsylvania Homes

  • Extend your kitchen into a rear addition

  • Create space for a large island or breakfast bar
