42541 Cambria Modern Twin is a 3,110 sq ft duplex house plan engineered with a 42-foot width and 45-foot depth, optimized for narrow urban infill lots. The design features a two-story vertical configuration with a 6:12 roof pitch and a total building height of 25 ft 1 in, providing a contemporary profile while maintaining structural efficiency.
The first floor spans 1,350 sq ft and includes a 520 sq ft, 2-car front-load garage. This level is anchored by a private office, one bedroom, and a full bathroom, establishing a self-contained zone suitable for remote work or multi-generational requirements. An 80 sq ft covered front porch provides a sheltered transition from the exterior to the internal mudroom entry.
The second floor offers 1,760 sq ft of living space, functioning as the primary social and private core of the home. This level contains the main kitchen, a secondary kitchen, and an expansive family room. The layout provides two distinct floor plan configurations for the upper level, allowing owners to prioritize either additional bedroom count or expanded storage and entertainment zones. Four full bathrooms and two half bathrooms are distributed across the levels to support high-density usage.
Construction specs include 9-foot ceiling heights on both the first and second levels, which allow for consistent natural light penetration and a sense of volume within the living areas. The design emphasizes modularity, ensuring that the footprint remains compact while maximizing the total heated living area to 3,110 sq ft.
Key Features: 4 bedrooms, 4 full bathrooms, 2 half bathrooms, 2-car front-load garage, dual kitchen configuration, first-floor home office, walk-in pantry, covered front porch, two-story duplex design, multi-generational layout, 6:12 roof pitch.
