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…
  • Working with a narrow lot under 40 feet wide (20 ft width, 30 ft depth)
  • Need a home office or flexible workspace (527 sq ft mezzanine bonus room)
  • Want the master suite completely separated from guest areas (third-floor master with full bath, cluster bedroom on second floor)
  • Seeking finished lower-level space with exterior access (walkout basement, 536 sq ft finished)
! May not be the best fit if you…
  • Prefer single-story or avoid multiple levels (three-story design with vertical circulation)
  • Need 3+ bedrooms (plan includes 2 bedrooms plus bonus room only)
  • Seeking a compact total footprint to minimize build costs (2,464 sq ft total including basement and mezzanine)

This plan tends to appeal to:

About this plan

Vertical Contemporary Home for Narrow Lots

Keystone is a three-story contemporary house plan engineered for narrow lot constraints, measuring just 20 feet in width and 30 feet in depth. This vertical design uses 1,337 square feet of heated living area efficiently, with a walkout basement foundation adding 536 square feet of finished space. The exterior reaches a maximum height of 41 feet, defined by an 8:12 roof pitch that complements its modern aesthetic.

The second floor features an open-concept kitchen with a central island, breakfast area, and 527 square feet of loft-style mezzanine bonus room suitable for a home office, media area, or studio. The entire third floor is devoted to the master suite with a walk-in closet and full bathroom, creating a secluded primary retreat. A cluster bedroom configuration on the second floor separates the primary suite from secondary sleeping quarters. All main living levels feature 9-foot ceiling heights.

The walkout basement provides direct exterior access and additional flexible space, while the narrow footprint makes efficient use of tight urban or hillside lots. With 2 bedrooms, 2 full bathrooms, and 1 half bathroom across 2,464 square feet (including basement and bonus), this design balances privacy and shared living.

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.
