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…
  • Building a coastal home on a pier foundation with compact width—the design is 40 feet wide and fits tight waterfront lots
  • Want a guest suite on the main floor separate from the primary suite upstairs (4 bedrooms, 4.5 baths)
  • Love extensive covered outdoor living—1,151 sq ft total porch area plus open deck
  • Need an optional bonus room for media, hobby, or guest flexibility in addition to the 4 bedrooms
  • Prefer second-floor laundry near the bedrooms to minimize chore transit
! May not be the best fit if you…
  • Need a first-floor master suite—the primary suite is on the second floor
  • Want a single-story layout without stairs
  • Prefer a wide footprint—this design needs 40 feet width but maximizes depth
  • Seeking a more compact overall footprint to reduce build costs (3,121 sq ft across two stories)

About this plan

Two-Story Coastal Home with Dual Master Suites and Extensive Outdoor Living

Haddies Hideaway 1 is a 3,121 sq ft two-story coastal residence designed for a compact 40-foot width and 56-foot depth on a pier foundation. The structure features 2x6 wall framing, a 4:12 roof pitch, and reaches 36 ft 9 in in height. The exterior is defined by 1,151 sq ft of total porch area—193 sq ft covered front porch and 958 sq ft rear porch—providing exceptional outdoor connectivity and coastal weather protection.

The first floor (1,686 sq ft) centers on a keeping room, kitchen with island and walk-in pantry, dedicated home office, and a guest suite with half-bathroom. Nine-foot ceilings maintain consistent volume. The second floor (1,435 sq ft) houses the primary suite with private bathroom and walk-in closet, plus secondary bedrooms with walk-in closets and a second-floor laundry room. An open deck provides private outdoor space, and nine-foot ceilings continue the vertical scale.

A 975 sq ft front-load 2-car garage anchors the ground level, while an optional unfinished bonus room offers flexibility for media, hobby, or guest sleeping space. The pier foundation and extensive covered porch area make this plan ideal for elevated coastal or waterfront sites.

Key features include 4 bedrooms, 4 full bathrooms, 1 half-bath, first-floor guest suite, second-floor laundry, home office, walk-in pantry, optional bonus room, and coastal architecture optimized for elevated construction.

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.
