Is this the right plan for you?

Most regret comes from buying a plan that doesn't fit your life. Skim this before you decide.

Great fit if you…
  • Have a wide lot of 88+ feet — this design is engineered for 88 ft 8 in width and 95 ft 4 in depth
  • Want flexible bonus space — 301 sq. ft. bonus room functions as exercise room, guest cabana, or bedroom
  • Frequently host guests or multi-gen family — 4 bedrooms, 4 bathrooms with split-bedroom privacy
  • Love outdoor living — 915 sq. ft. lanai plus covered entry significantly extends entertaining space
  • Prefer single-floor living with first-floor laundry — all utilities and laundry on main level
! May not be the best fit if you…
  • Working with a narrow lot under 85 feet — this design's 88 ft 8 in width is a requirement
  • Need a compact footprint — 3,650 sq. ft. plus 915 sq. ft. lanai creates a sprawling floor plan
  • Prefer a two-story layout — this is a single-story design with limited vertical expansion
  • Want fewer than 4 bedrooms — the base plan includes 4 bedrooms and may exceed your needs

About this plan

Mediterranean Single-Story Home with Bonus Room and Lanai

Spanning 3,650 square feet, this Mediterranean house plan is designed for wide lots, measuring 88 feet 8 inches in width and 95 feet 4 inches in depth. The split-bedroom configuration isolates the first-floor primary suite from secondary bedrooms, while the open-concept kitchen, keeping room, and formal dining area form the social core of the home.

The kitchen features a central island and breakfast area with clear sightlines into adjacent living zones. A dedicated home office provides workspace, while a 301-square-foot bonus room offers flexible utility as an exercise room, guest cabana, or additional bedroom. Four bedrooms and four bathrooms accommodate multi-generational living or provide guest flexibility.

A 915-square-foot rear lanai and 145-square-foot covered entry expand usable outdoor space significantly. The first-floor laundry room and 698-square-foot 3-car garage ensure efficient home management. A slab foundation and modest 26-foot 1-inch building height maintain a low-profile aesthetic suited to coastal and inland settings.

We compared three plan sources and Archival's pricing + free design call won us over. Our builder said the construction docs were the cleanest he'd seen.
