Terwillegar Towne is one of the seven neighbourhoods within the Terwillegar Heights Servicing Concept Design Brief (SCDB), and is located roughly in the centre of the plan area. The neighbourhood is bounded by 23rd Avenue to the north, Rabbit Hill Road to the east, Terwillegar Boulevard to the south and Terwillegar Drive to the west.
Terwillegar Towne was the first community in Edmonton to be planned and built in a neotraditional design model, and provides an example of a New Urbanism-style development within the city. New Urbanism features include roadways designed to encourage pedestrian use, houses situated closer to the street to encourage interaction among residents, vehicular traffic that is dispersed throughout the neighbourhood, and a Towne Square to provide the foci for the community.
The neighbourhood began developing in the late 1990s, and development continued into the 2000s. Residential units in Terwillegar Towne are found within single and semi-detached homes, row houses and apartment-style buildings. Commercial space is provided in the town centre, located along Terwillegar Boulevard on both sides of Towne Centre Boulevard. Two school sites have been provided in Terwillegar Towne. One site is located adjacent to the town centre east of Towne Centre Boulevard and the other is located on the western side of the boulevard in roughly the centre of the neighbourhood. The Leger Transit Centre is located on the northern edge of the neighbourhood along 23rd Avenue, which is also where the new Southwest Recreation Centre is located.
Terwillegar Towne was named in honour of Dr. Norman L. Terwillegar (1884-1948). Dr. Terwillegar was a pioneer, a surgeon, and a local property owner in the area for many years. Terwillegar practiced medicine in the Edmonton area between 1912 and 1947 and was on staff at the Royal Alexandra Hospital for over 35 years. He also served as president of the Alberta Division of the Canadian Medical Association as well as for the Edmonton Academy of Medicine.
