Cruising down Skillman Avenue this past weekend, we were struck by the extremes of these two houses. The house on the left at 173 Skillman is pretty cool, we think. (See, haters, we don’t diss everything new.) It’s a modernist play on the vernacular of vinyl siding so common in Williamsburg and Greenpoint. We’re dying to know more about it. The house on the right at 179 Skillman is, well, we’re at a loss for words. Who can give their best architecture grad-student critique of this place? GMAP
