"I found a picture of a sunroom that was my dream room, windows everywhere and curved wood beams. We found a little Scandinavian fireplace to go in a corner and still have room for all of our windows. The woodworking is outstanding the travertine floors are great but the beams are the highlight of the room and everyone’s favorite. Trent is very accommodating, willing to find solutions and an excellent craftsman."
