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…
  • Need a true in-law suite for multi-gen living (418 sq ft garage apartment with full kitchen)
  • Working with a narrow lot under 40 feet — this design is 19 feet 8 inches wide
  • Want a main-floor owner's suite for accessibility (first-floor master suite)
  • Need a 2-car garage on a tight footprint (2-car rear-entry garage)
  • Seeking rental income potential or guest independence (self-contained in-law suite)
! May not be the best fit if you…
  • Need 4+ bedrooms for a large family — this plan has 3 bedrooms plus an in-law suite
  • Want a single-story layout — this is a two-story design with stairs between levels
  • Prefer a sprawling footprint — this narrow design prioritizes vertical space (1,548 sq ft on 19 ft 8 in width)
  • Need main-floor laundry — laundry is located on the second floor

About this plan

The Boston house plan is a two-story residence engineered for narrow lots, measuring 19 feet 8 inches in width and 68 feet 6 inches in depth. Spanning 1,548 square feet of total heated living area, this design maximizes site density while providing a distinct separation between private and public zones. The exterior profile features a maximum building height of 25 feet 6 inches, utilizing a combination of 1:12 and 5:12 roof pitches to maintain a low-profile silhouette suitable for urban infill.

The first floor encompasses 1,005 square feet, anchored by an open-concept great room that flows into the kitchen and dining areas. A 10-foot ceiling height throughout this level increases the perceived volume of the interior. The primary suite is located on the main level, providing direct access to the living core, while a half-bathroom serves as a guest powder room. The kitchen includes a central island and a breakfast nook, creating a focal point for daily activity.

The second level adds 543 square feet of living space, featuring two secondary bedrooms and a full bathroom. With 9-foot ceiling heights, the upper level maintains a comfortable scale for residents. The inclusion of a 74-square-foot bonus area provides additional storage or utility space, while the 418-square-foot garage apartment, positioned above the 2-car rear-entry garage, serves as a self-contained in-law suite or rental unit.

Construction specifications include a slab foundation and stick-framed roof assembly. Exterior amenities are distributed across 146 square feet of total porch space, comprising a 68-square-foot front porch and a 78-square-foot rear porch, alongside a second-story balcony. This layout ensures that both interior and exterior transitions are utilized to support a multi-generational living arrangement within a compact footprint.

Key Features: 3 bedrooms, 2 full bathrooms, 1 half-bathroom, in-law suite, rear-entry 2-car garage, first-floor primary suite, slab foundation, front and rear porches, balcony, open-concept floor plan.
