55,000 sq ft green roof

This  55ksf  extensive  green  roof  serves  multiple  functions.  While  the  local  environment  benefits from  a  reduction  of  the  heat  island  effect,  minimized  storm  runoff  and  added  protection  to  the roof  membrane,  this  sedum  green  roof  transforms  a  series  of  bare,  unattractive  spaces  into  a vibrant,  lush  amenity  for  the  residents  of  this  new  development.  The  green  roof  is  perhaps  the most  visible  element  of  the  suite  of  high  end  amenities  and  finishes  envisioned  by  the  developer,  and  emblematic  of  the  continuing  evolution  of  this  historic  neighborhood.

9,500 sq ft of Dumbo rooftop…

On the Brooklyn waterfront nestled between the Brooklyn and Manhattan Bridges is 45 Main Street, a 475,000 square-foot office building and one of the signature properties of the neighborhood known as DUMBO. Here, developer Two Trees Management has converted the former factory building to create a mix of private and co-working spaces with incredible views a short walk to the waterfront. With the ground floor dedicated to retailers and the arts, the rooftop is a 9,500 square-foot shared space designed by Landscape Architect James Corner Field Operations and built by Blondie’s Treehouse Inc. We retrofitted the rooftop on this historic building with a mix of stone and wood surfaces. A herringbone pattern of grey and white granite creates a distinct area for blue bistro tables. In the south section of the rooftop an elevated ipe platform introduces an additional level for more casual lounging. Large planters of weathered Corten Steel feature Gleditsia, Amalenchier, Dogwood and Witchhazel as well as perennials and grasses. Custom ipe benches create privacy seating and serve as space dividers along the north and east walls. To install this project on time, Blondie’s brought in a 140-ton crane and secured permits allowing the closure of Washington Street. In a single morning, we lifted 250 cubic yards of soil and drainage stone, twenty-five 15’ trees, each with 30” root balls, 1,600 one gallon perennials as well as pavers and a variety of construction materials. Without the crane, this material would have required the freight elevators for a solid week, a difficult prospect in a busy building at full occupancy. Over a period of nearly four weeks, Blondie’s craftsmen and gardeners fabricated custom woodwork and planters and carefully planted thousands of perennials, shrubs and trees, transforming this rooftop from an empty and unutilized space into a fully realized, functional and quite gorgeous urban landscape.
