Keystone is a contemporary three-story house plan engineered for narrow lot constraints, measuring just 20 ft in width and 30 ft in depth. This vertical design utilizes 1,337 sq ft of heated living area to maximize efficiency, incorporating a walkout basement foundation that adds 536 sq ft of finished space to the total footprint. The exterior profile reaches a maximum building height of 41 ft, defined by an 8:12 roof pitch that complements its modern aesthetic.
The main level provides 64 sq ft of utility space, serving as the base for the vertical circulation. The second floor encompasses 600 sq ft, housing the primary social core. This level features an open-concept kitchen equipped with a central island and a breakfast area, facilitating direct sightlines across the floor. A loft-style balcony enhances the sense of volume, connecting to a 527 sq ft mezzanine bonus room that offers flexible square footage for a home office, media area, or studio space.
Occupying the entire 600 sq ft third floor, the master suite provides a secluded environment with a dedicated walk-in closet and a full bathroom. The internal layout includes a total of 2 full bathrooms and 1 half bathroom, with a cluster bedroom configuration that promotes separation between the primary suite and secondary sleeping quarters. Ceiling heights of 9 ft on both the first and second levels contribute to the vertical scale of the interior.
Structural integrity is maintained through a combination of finished basement utility and elevated living zones that leverage the narrow building site. The walkout basement provides direct exterior access, increasing the utility of the lower level, while the overall design prioritizes efficient circulation between the three levels. With a total area of 2,464 sq ft including basement and bonus space, this home accommodates modern requirements for privacy and communal gathering.
