remodeling up the street

There's a house up the street and round the corner with - as you can see - amazing views. But it's also clearly in terrible condition.  It's being slowly renovated  - very slowly - very slowly indeed - one of those jobs where they clearly have to keep enough of the walls for it to be, technically, a remodel rather than a tear-down and build something new.  What intrigues us is the front door, because it clearly has a large panel of stained class that's almost identical to the one that we have on our second floor door to an outside staircase, and that was made at Judson studios, in Highland Park, in the 1970s. Will they keep it?  Will the door be taken out and sold to a salvage or architectural antiques company?  Of course it would be great if it stays: the speed of work is so glacial, though, that it's hard to predict when any decision will be made on its future.
