Indoor/Outdoor Living, its effect on appreciation of home values?

[Christian Solinski]

Currently, I have a full time job in the fenestration business, and I was legitimately curious if the whole concept of "indoor/outdoor living" had a major effect on home values. 

For those that may not know, the fenestration business is simply know as the window/door market. "Indoor/outdoor living" is the concept of putting in a huge sliding glass door (the size of a whole wall), for instance, that would, when open, combine a backyard and living room into one free flowing state. Obviously, you would not do this if you did not have a good backyard.

Market research indicates that renovations, and subsequently, "indoor/outdoor living", are very popular right now.

For a personal perspective, would it be worth it to put these types of products in a Class B home, in a Class A or Class B neighborhood? Only downside ... most of these types of products are incredibly expensive (I would obviously account for the cost when calculating cash flow).

This would be a visual example of what I am talking about...
