The Growlery originally had three very small windows which were really beyond refurbishing. Then I caught a little luck, and coupled with a little cutting and banging boards around, I got two new windows.
The large window was part of an earlier remodel of the house next door, which was then razed last Fall. I got the window. It's a good window, double-glazed, low-E glass, etc. John Rust and I enlarged the opening (a lot) and we put it in the south wall where it would maximise my sunlight.
I was going to just block off the other two windows, but I would have lost cross-ventilation and the view to the north from my desk chair. The other day I was visiting Tom Furleman looking for a keeper for an antique rimlock. Tom sells a number of lines of replacement windows and I noticed his sample windows were about the same size as my original little windows. We struck a deal. I came away with an extra sample window and he got rid of one.
