Thanks for the great comments! I, too, hate the loss of space for the other door. I tried to place the darkroom in the other space, but there were too many incursions from a/c & sewer plumbing. There is not enough sheer wall clear height to place the doors elsewhere.
I have sketched making the "enlarger end" into a "u" shaped counter area,, but because of the narrowness of the floor space, I felt that I lost nearly as much accessible counter space in the corners as a I gained. But I will play with the counters some more. BTW, I will put shelving darn near everywhere!!
Thanks to all for the comments.
