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…
  • Hosting guests regularly—includes a dedicated guest suite on the main floor
  • Working from home—home office on the first floor (3,464 sq ft, two stories)
  • Building on a narrow coastal lot (42 feet wide, pier foundation)
  • Want substantial outdoor entertaining space (703 sq ft combined porches, 557 sq ft decks, outdoor fireplace)
  • Need four bedrooms across two floors (4 bedrooms, 4.5 baths)
! May not be the best fit if you…
  • Require all bedrooms on one floor—bedrooms are distributed across two stories
  • Want a main-floor master suite—the primary suite is on the second floor
  • Need 5+ bedrooms—this plan has 4 bedrooms total
  • Building inland without coastal requirements—pier foundation is engineered for waterfront sites
  • Prefer a single-story layout—this is a two-story design

This plan tends to appeal to:

About this plan

Four Bedrooms with Loft Flexibility on a Narrow Lot

This two-story coastal house plan delivers 3,464 square feet of heated living space, optimized for a 42-foot width and 69-foot depth footprint. Engineered with a pier foundation and 2x6 wall framing, the design is built for waterfront and low-country sites where elevation and structural durability are essential. The 4:12 roof pitch creates a lower-profile exterior suited to beach and lake environments, reaching a maximum building height of 37 feet 8 inches.

The first floor encompasses 1,933 square feet anchored by a great room that integrates with a kitchen island and walk-in pantry. This level includes a guest suite, home office, and half bathroom. Outdoor connectivity is extensive: a 421 square foot covered front porch and 282 square foot rear porch, complemented by an outdoor fireplace for exterior gatherings. An internal elevator provides vertical accessibility.

The second floor spans 1,531 square feet and houses the primary master suite with ensuite bathroom and walk-in closet. Additional bedrooms share the upper level with a loft area, and occupants enjoy access to both covered and open decks totaling 557 square feet. Ten-foot ceiling heights on the first level and 9-foot ceilings on the second create distinct volumetric experiences. A 1,933 square foot 2-car garage provides substantial utility and storage below the main living zones.

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.
