Looks like the carriage house is in the rear attached to the main building and there appears to be a hot house on the side. It's impossible to say for sure which way the home faced... although, IF that is present day Gladstone Boulevard in the foreground the house faced either west or north... I'd bet on west...
There are no visible remains of this home now.... it would be fun to do amateur archeology on the site but I think the present occupants of the three homes there now would probably object.
