What Defines a Mansion House Plan?

The term “mansion” traditionally refers to a residence exceeding 5,000 square feet, often situated on expansive properties. Our mansion house plans not only meet these criteria but go beyond by incorporating thoughtful details such as porte-cocheres, grand foyers, multi-car garages, private guest suites, and entertainment wings.

From Mediterranean villas to Georgian estates, every design prioritizes space, flow, and function while maintaining timeless beauty. And with access to editable floor plans, homeowners can tailor their dream estate to reflect their personal style.

Top Features Found in Our Mansion House Plans

  • Heated square footage starting at 5,000+ sq. ft.
  • Multiple levels, often with finished basements and attic suites
  • Grand entrances with double staircases and multi-story foyers
  • Chef-style gourmet kitchens and butler’s pantries
  • Dedicated home theaters, libraries, wine cellars, and fitness rooms
  • Indoor/outdoor entertaining areas with large decks, porches, and courtyards
  • Primary suites with spa-inspired bathrooms and expansive walk-in closets
  • Guest quarters, in-law suites, or dual owner’s retreats
  • 4–6+ car garages, including RV bays and golf cart storage
