Discover Your Ideal Prefab Home in Maryland

Most prefabricated homes in Maryland are Cape Cod, contemporary, ranch, or two-story styles, each offering charm and unique benefits. At Guardian Homes by Keystone, we  have several prefabricated home styles to choose from, including:

  • A-Frame: With its striking triangular silhouette and expansive windows, this design delivers bold curb appeal and stunning natural light.  
  • Cape Cod: Featuring steeply pitched roofs and balanced floor plans, Cape Cod-style homes blend timeless charm with a warm, inviting atmosphere.
  • Colonial: This elegant style includes a stately entryway and signature columns, offering a classic, refined look rooted in tradition.
  • In-Law Suite: Designed for flexibility, this layout adds apartment-style space or an additional wing — ideal for hosting extended family or long-term guests. 
  • Rancher: A single-story layout with open living areas and attached garage access makes this design practical and easy to navigate.

Customize Your Maryland Modular Home

We offer a comprehensive selection of standard features and optional upgrades so your modular home aligns with your preferences and lifestyle. Our standard offerings include customizable floor plans, Andersen high-performance windows, custom cabinetry, stainless steel kitchen sinks, and durable CertainTeed roofing and siding. We also prioritize safety with features like radon venting systems, carbon monoxide detectors, and AC/DC smoke detectors in bedrooms and corridors. 

For those who prefer even more personalization, we offer optional features like custom fireplaces, HVAC systems, exterior finishes, structural additions, lighting configurations, doors and windows, stairs and railings, storage solutions, cabinetry, appliances, and more.

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.
