When an architecture firm has been around as long as the 83-year-old Skidmore, Owings & Merrill, it may see some of its buildings receive landmark status, and it may also, on occasion, have to see some of its structures knocked down.

Such was the case with the 12-story Skidmore-designed former headquarters of the American Bible Society, at the southern end of the Upper West Side, which the nonprofit organization sold to the developer AvalonBay Communities in 2015 before relocating to Philadelphia.

Still, even when the building in question wasn’t universally admired to begin with — a Brutalist structure built in 1966, later compromised by an awkward glass addition on the front — the demolition of a “legacy” building, as architects call the works their firms have created, comes with a sting.

“That haunted us,” said Chris Cooper, a partner at the firm. “I’d be lying if I said it didn’t.”

It also spurred Skidmore to beat out competing architecture firms for a chance to design the replacement building on the northwest corner of Broadway and West 61st Street: a 32-story, 172-unit condo residence named Park Loggia whose units go on sale this month.
