  Re: SG Blocks, Inc. (the “Company”)
    Amendment No. 1 to Form S-1
    Filed December 5, 2011
    File No. 333-178321
 
To Whom It May Concern:
 
Concurrently with the filing of this letter, the Company has filed Amendment No. 1 to its Registration Statement on Form S-1 (the “Amendment”).  The Amendment primarily reflects revisions to the initial filing of the Company’s Form S-1 as a result of addressing staff comments to the Form S-1 and the Company’s Current Report on Form 8-K initially filed November 10, 2011 (the “Current Report”).  The Amendment also includes certain other updated information.
 
Per our discussion with Aslynn Hogue, the Company deferred the filing of the Amendment until all overlapping comments with the Current Report had been resolved.  Now that the overlapping comments have been addressed, the Company would greatly appreciate it if the Registration Statement is declared effective by the Staff during the week of February 6, 2012.
 
If you have any questions or request any further information, please contact either the undersigned at (212) 451-2252 or by email at kschlesinger@olshanlaw.com or Johnathan Duncan at (212) 451-2245 or by email at jduncan@olshanlaw.com.
