We used Jed Dinger (jeddinger.com) to build in a reading nook into one of our bays. Well thought-out design that gives us exactly what we wanted from the space without seeming an overly heavy addition to the room. It was really fine craftsmanship and well worth the cost. He built everything in his shop and installed it in a single day. The install took a day because he scribed everything perfectly to the wonky floors/walls of our old house.
