Park Slope Green Roof and Deck Design

Here is a green roof and deck we are designing for a job in Park Slope Brooklyn. The deck area ranges from 900-1100 square feet. It would be made out of salvaged fir or possibly Black Locust if budget permits.

The pergolas are intentionally without many beams. The vegetation will be the main source of shade. The green roof would be a shallow growing medium of 2-3 inches.

The client is a condo board so we are building the deck and green roof across their four buildings.

Our architect Nic Liberis did a great job at making the area look attractive. There are several design considerations to choose from.


Option 1

Long board walk along the length of the buildings with pergolas covering part of it. This has the benefit of keeping people away from the doors where there could be sound issues. The drawback is that there is not that much privacy, which could be resolved with planters.

Option 2

This has the hang out areas in between the bulk heads, providing more privacy and possibly protection from the elements. The one drawback is the possible sound issues of people on the roof bothering residents below through the stairway.

This is the same option without the plant renditions:

Option 3

This option is the same as option 2 except a trellis has been added. For more protection from wind and more shade.

    Hello All, I vote for option I.

    I also like option 1. I feel that for a 7200 square foot deck, we must have more than 900-1000 feet of decking, particularly b/c part of that square footage is path space. I think the only place to really add decking is to the existing decking itself– even if we extend it completely to the wall. Right now, there is green space adjacent to the decking leading to the wall (which overlooks street). I suggest making this entire space decking. What could also happen because of this minimal decking is that people may walk on the grassy space by the deck b/c the decking area is so cramped.

    I think Option 1 is promising. It needs more deck area. Also, the bulkhead should not intersect the deck. The deck should be a full rectangle. We could move the whole deck away from the bulkhead, toward the street, so that it could be lined on both sides with green. Or we could move the deck all the way to the edge of the roof? And I definitely think we should green roof the rest of the roof down the road, money permitting.

    Not a fan of option 2, not enough deck space.
