Enjoy being surrounded by nature and yet convenient to transit, shops and restaurants in the Forest Hill Village and along Dupont Street.

The photos attached are: renderings of the approved house, possible renderings of limestone facades, existing lot and house photos, and some historical photos of the Ardwold "High on the Green Hill" Estate.
