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…
  • Multi-generational families needing in-law independence — a self-contained in-law suite with its own entrance and facilities
  • Entertaining and outdoor dining — 633 sq. ft. lanai with outdoor kitchen plus rear porch and front entry porch
  • Building on a wide lot — this design is engineered for 80 ft 8 in of frontage and accommodates the footprint
  • Need 4 bedrooms plus flexibility — 4 finished bedrooms with split-bedroom layout, plus loft space on the upper level
  • Work from home — a dedicated home office integrated into the main floor near the entry
! May not be the best fit if you…
  • Need a single-story layout — this is a two-story plan with stairs to the loft and upper level
  • Working with a standard 60-foot lot — this design requires 80 ft 8 in of width
  • Want a compact, affordable footprint — 3,469 sq. ft. across two levels is a substantial estate plan
  • Prefer all bedrooms to be identical in size and location — split-bedroom and loft layouts create varied room configurations

This plan tends to appeal to:

About this plan

Mediterranean Estate with In-Law Suite and Flexible Spaces

This Mediterranean-style beach house delivers 3,469 square feet across two levels, engineered for wide coastal lots with an 80-foot 8-inch frontage. The 2,515-square-foot main level is anchored by an open-concept great room and gourmet kitchen featuring a central island and eating bar. A first-floor primary suite with split-bedroom configuration ensures privacy, while a self-contained in-law suite and dedicated home office provide flexibility for multi-generational living or remote work.

The 954-square-foot second level includes a loft space with balcony, creating a secondary living zone that maintains separation from the main social areas. A two-story foyer enhances natural light distribution throughout the interior. Outdoor entertaining is prioritized: a 633-square-foot lanai with outdoor kitchen, rear porch, and 111-square-foot front porch extend living space. The 853-square-foot three-car garage and stucco exterior with CMU wall framing deliver durability for coastal environments.

  • In-law suite integrated into the main floor plan for multi-gen flexibility
  • Split-bedroom layout with first-floor primary suite and secondary bedrooms separated
  • Loft space on the second level for bonus living or guest retreat

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.
