An attached single-family residence with two levels of living area, with the lower level being fully finished and normally partially below grade (with no basement below it). The entrance is a split-foyer entrance. Each bi-level rowhouse unit is one of a group of two or more units joined by common walls. Such units never have units above or below, always have individual exterior walls and never have more than two walls common with adjacent units. A Center Unit is inside a row, with other units on either side. This style is especially common throughout Canada.
