THIS c.1900 BROOKLYN ROW HOUSE is about as green as you can get without being LEED-certified. The DUMBO architecture firm Delson or Sherman took on the job of converting the three-unit house, which had had the same owner for 50 years, into a single-family residence.

The building is chock full of sustainable strategies, including radiant heat flooring, solar water heating, spray foam insulation, a high-efficiency boiler, and a whole-house fan. Daylight is maximized by enormous skylights, as well as the replacement of one-third of the back wall, left, with expanses of glass. Materials were re-purposed whenever possible, even the little ‘Juliet’ balconies at the rear of the house, which are segments of the original fire escape.

It’s now utterly sleek and modern, which aroused a furor today on Brownstoner, with comments flying pro and con. Go here to see and read it all.
