The historic ''Wilson'' house in the heart of Flagstaff is ready for a new owner to call it home! With all the details that make an older home beautiful - including a coffered ceiling, built-ins and window seats all along the north wall -this home is special. The ample yard has room to entertain and garden to your heart's content. The extra-long garage was the original carriage house. Modern touches include an updated kitchen, newer windows and a Trombe wall to provide passive heating and a warm space to start plants in early spring. Once the home of the town doctor, it still has the sink in the front office which was once Dr. Wilson's consultation room.
