We stumbled upon a fantastic blog that documents wood-framed Brooklyn row houses, a type of building that hasn't been constructed in over 100 years due to the fire hazard it poses. The above image depicts a block with some colonnaded houses on Humboldt Street in 1935 Greenpoint. See how it looks now after the jump.
Though most of the columns have been removed, you can still make out the shapes of the houses and compare their current iterations with those from the past. Building materials have certainly changed in the past decade, and those that we now consider to be more wholesome (such as brick and stone) are oftentimes replaced with synthetic siding. It's fascinating to judge the character of a neighborhood against its former self. The Wooden House Project features lots of helpful information about bygone structures, and also directs readers to city photo records of buildings, so that you can see what came before on your own block.
