Popular as a cottage with room for toys, as an interim dwelling while the main house is being built, or as a guest suite or mortgage helper, this little dwelling unit packs a lot of features into a small footprint. The ground floor features a one-car garage with workshop, laundry and interior or exterior access to the staircase. At the top lies an open-concept living area with an eat-in kitchen and living room. Two bedrooms share a bathroom with bathtub and separate shower. In high-density areas, this is an excellent design, including all expected amenities and an attached garage.
