Drawing from the original (rejected) application to DOB, from the pro-construction website www.711westend.com |
The developers insist that they are not enlarging the existing building but instead constructing a new one (see PDF below.) In their original application, they claimed there were no existing tenants (on the logic that they are "only" constructing a new building.) With objections from the tenants and elected officials, they have now acknowledged the tenants.
The developers' claim that they are working on an unoccupied building appears to be a pre-planned use of a lapse in NYC codes. The project could not be approved under past or current code, but was submitted during a brief period when the building code was not in effect. See this post for details.
The permit applications to DOB include a smattering of upgrades and changes to the existing building. Submitting those permit requests piecemeal is viewed by some as an end-run around DOB; a tactic for preventing DOB from considering the large-scale project as a whole.
