In reading the listing description one passage is revealing, notably, the part where the 1915 parcel could be combined with the 1931 Second Ave lot. According to the Daily Journal of Commerce, who first reported this story, it was news to the people behind the 1931 project (Columbia West and The Justen Company):

“That’s unbelievable,” [Justen's Marty] Goodman said of the listing. “We’ve had discussions with them (Intracorp). We haven’t had discussions with them about listing our property as a potential assemblage.”

Update: Interesting…the Intracorp’s interactive Domain Condo website has been replaced with a “priority registration” page. Intracorp previously listed this property for sale as apartments on the Moran and Co. website.

Update 8/13: I’ve been trying to obtain confirmation on the status of Domaine to no avail…seems Intracorp is keeping mum. I wouldn’t be surprised if Domaine joins Expo62 (Axis) and Moda given they’ve closed their sales office, removed signage, dummy downed the website and are media shy (not me…the DJC and PI).
