It’s Retail Week over at the Municipal Art Society’s New Penn Station blog.  As they point out, the  Moynihan Station project proposes 1.1-million-square-feet of retail development for Moynihan East, the new train station that will rise on the current site of Madison Square Garden.

But what exactly does that mean?  This post attempts to quantify that huge number (hint: it’s 9 times the size of the retail space at Grand Central Terminal).  “Is it possible,” they ask, “for any architect to realize an ‘iconic and distinctive’ train hall with ‘well lit, spacious concourses’ if it must be surrounded by the equivalent of 3 Time Warner Center malls? Or 10 Target stores?”  MAS suggests spreading the development throughout the subdistrict, rather than concentrating it in one area.

What do you think?  Will a concentration of retail help revitalize the area, or will it detract from the mix of new and historic buildings?  What kind of retail would you like to see on this site?
