4th Avenue Concrete Giant Shadows Last Remaining Wood Frames.

548 Fourth Avenue. Architect Felix Tambasco designed this R8A zoned 9 story 93 foot tall apartment building going up quickly now on the corner of 15th Street in Gowanus.  We're looking at a sum total of 26,159 square feet divided into 15 dwelling units as well as a 691sq ft community facility space, and a required commercial/retail space of 1,697 sq ft at the street level. 

As seen from directly across Specially Enhanced Fourth Avenue standing in the parking lot of the now bankrupt for almost a year, now shuttered  Strauss Auto Center.  No plans have been filed by XYZ Property for this mega block long development site as of yet.

Star Spangled Banner Yet Waves
Still occupied, the well maintained 137 15th St. pictured on the left clad in patriotic red siding and its sister the already doomed to destruction 139 15th St. slam up against the new 9 story development.  ACRIS shows 139 15th, the 22 by 100 foot deep property, traded hands in 2010 for $330,000... A speculators bargain I would think considering same size lots farther up the Slope go for at least two to three times that price. 

Still standing, BEST Squad approved a mechanical demo permit of all things way back in December of 2010.  A prerequisite to extermination, rat bait stations and posted yellow warning signs.  Original? floor to ceiling double hung windows and what remains of a wooden porch and concrete stoop.  Some kind of cellar exists below the house with additional windows and door, now boarded up and filled with mud. 

A front facade covered with asphalt shingles, two brackets left exposed while the entire cornice has been hermetically sealed in a layer of tin flashing.

Second story window details. Nice bracket...

139 15th Street.  Plans have been approved for a 50' tall, four story with penthouse, 8 family apartment building to contain some 10,720 square feet of floor area. No off-street car or bike parking is required.

 In this 1924 aerial photograph showing the blocks just below 4th Avenue you can see the row of attached frame houses.  Fourth Avenue is considered the border between the neighborhoods of Gowanus and Park Slope South.
