Styles of Modular Homes in Pennsylvania

Explore endless possibilities with Guardian Homes by Keystone. Our professionals can answer your questions and offer guidance in choosing a prefab home that best suits your preferences and lifestyle goals.

We offer ranch modular homes with practical layouts and easy accessibility. Each single-story dwelling features a low-to-the-ground profile, an open floor plan, large windows, and an attached garage.

If you’re looking for a charming and timeless appearance, consider our Cape Cod modular homes. We offer New England- or European-inspired architecture and customizable floor plans.

Create a grand appearance with white columns highlighting your home’s architecture. Our colonial prefab homes typically have multiple stories and showcase a balanced design with symmetrical windows.

Make a statement with bold, triangular designs. Our A-Frame modular homes feature unique architectural elements, soaring ceilings, and expansive windows that allow you to embrace natural lighting.

Give your extended family members or guests privacy with separate accommodations. We build in-law suites within or attached to a main home. The apartment-like areas often feature a bedroom, bathroom, and kitchenette to support independent living.

After we found our property we began to put on paper what we wanted our house to consist of. We went to a builder and two other modular companies. We were told that what we wanted could not be done.
