A rendering has arrived on the plywood outside the under-renovation 421 E. Sixth St. ...

It doesn't look too different from the existing building ... from the exterior anyway.
Here's a side-by-side look (as noted previously)… showing the existing building (left) and the proposed front...

The address between Avenue A and First Avenue was a Con Edison substation built in 1920-21 that converted direct current to alternating. Artist/sculptor Walter De Maria owned the building from 1980 to the time of his death in July 2013.
As previously reported, the building will be a gallery space to display new owner Peter Brant's personal art collection.
