This house is on a corner lot with large frontages on both sides. The frontage on the Ridgeline Road is almost twice wider than the regular lots across the street. Its value is the potential of this beautiful lot. It has the same width of frontage on the Rocky View Road. It has a gentle slope to the lot line. In summary, the house could be expanded to provide paramount curbside view from both streets. There is a total of five car garages, whereas thee are facing ridge line road, a fourth garage with side entrance currently used as an artist workshop and a fifth garage with 10 ft garage door for trailer or RV. The back courtyard paved with slate over concrete provides spaces for exterior living and cooking. Adjoin the courtyard is a good size swimming pool with a Jacuzzi on the side. (The pool has a crack at the sidewall and is currently not used)
