Aby Rosen has big plans for Trylons after boot from Chrysler Building

Aby Rosen is done with the Chrysler Building, but not with its little sister — the triangular-topped Trylons next door at 145-155 E.42nd Street.

Rosen’s RFR owns the now-vacant property outright, unlike the leasehold he previously held at the office tower.Rosen, who’s rebounding since Chrysler landowner Cooper Union booted him, has big plans for the low-rise, Philip Johnson-designed retail parcel wedged between the landmark tower and 666 Third Avenue at the corner.“This is a wonderful opportunity,” Rosen said.“We always had the idea to redevelop it.”Rosen and an Austrian partner bought Chrysler and the next-door Trylons in 2019 for just $150 million.

Although intended as an homage to Chrysler’s Art Deco lines, the Trylons were not regarded as among Johnson’s best work.Most of the space was home to Capital Grille steakhouse.“Between you and me, it’s rather ugly,” Rosen said.Rosen intends to lease the parcel, not sell it.

His options are open depending on market demand.The new building could be as relatively small as 100,000 square feet, for which he’d ask $10 million in ...
