20'x50' Modern Cabin Plan 2BR/2BA with Loft, 1,430 sq ft

Build a Modern 2-Bedroom Cabin with Loft: Complete House Plan Package

Looking for a small modern cabin house plan that lives large? This 20x50 loft cabin gives you 1,430 sq ft of heated living space on a narrow 20-ft-wide footprint, making it perfect for narrow lots, sloped sites, lakefront properties, backyard ADUs, vacation rentals, and first-time owner builders.

A Layout That Works Hard
The ground floor opens with a bright dining and living area (each 9'7" x 13'2") flowing into a 12'8" x 9'11" kitchen with island seating. A ground-floor bedroom, full bathroom with walk-in shower, and a utility room with washer/dryer, water heater, and furnace complete the main level. Upstairs, the 430 sq ft loft holds a private 11'7" x 11'11" bedroom, a second full bath with tub, two full-depth closets, and eave storage, with an open-to-below void that floods the living area with light from the clerestory windows. Outside, a cedar pergola-covered front porch with built-in benches and a rear deck extend your living space.
