A little bigger...but with a great deal of light and ventilation. So the windows are tall but split like this...

[A sketch comes together quickly under Kaveh's fingers. Windows with a smaller pane on top that opens out to ventilate, but otherwise span nearly from the ceiling to the floor for two thirds of the room. A small and cozy workspace with similar ventilation and a little chimney in the roof to allow the fumes to escape.]

Something like this, you think?
