Description
Designed for lots as narrow as 20 feet, this three-story townhouse maximizes every square foot while maintaining a strong street presence and comfortable proportions. Ground floor: single-car garage, entry vestibule, and a flexible room (home office, guest bedroom, or studio) with full bathroom and exterior access. Second floor: open-plan kitchen, dining, and living room with a small balcony off the living area. Third floor: primary suite with ensuite bath, one additional bedroom, and a shared bathroom. A roof deck with steel cable railing adds substantial outdoor living space — ideal for urban settings where yard space is limited. A light well on the north side brings daylight to the stairway and second floor. The plan has been built in Portland, Denver, and Austin infill lots. Zero-lot-line configuration available.
