Roof gardens are common enough but this suspended green oasis is something rather different. In fact there is a roof garden as well, but the particular feature is this “micro courtyard” which you can look up to and view while seated in your armchair below. In fact the article by Mitchell Parker which I found on the Houzz website is mostly about an amazing loft conversion but is well worth reading because of this intriguing feature.

Architect Andrew Franz didn?t want his clients to pass up an opportunity that comes only once in a lifetime. The couple, both in finance, were looking to buy a place in New York City that would require only modest renovations. But when Franz saw a messy unfinished studio with raw concrete floors, he urged his clients to jump on it.
Why? The unfinished unit occupied the top floor of a low-key building in Tribeca, one of New York?s most desirable neighborhoods. The top position gives the unit roof rights, meaning whoever renovated it could create a dramatic outdoor space ? an extreme rarity in the city ? overlooking the Hudson River. ?They would have carte blanche to do what they wanted with it,? Franz says. ?You don?t stumble on something like this every day.?
But if an outdoor space is hard to come by in the city, try an outdoor space indoors. To get that one-of-a-kind amenity, the couple and Franz punched a hole in the roof to create a suspended glass-encased garden that hangs like a green oasis right in the loft interior, shown here.
Franz felt that his clients might not be inclined to use a rooftop garden if it remained unseen. By dropping a portion of the garden into the interior, the homeowners can enjoy the view and be encouraged to venture up and outdoors. ?It?s like a micro courtyard,? he says.
The drop-down garden also allowed light to flood into the unit ?rather than cutting a million skylights in the roof,? he says.
