The owner's had just moved in when we took this photo. FInal furniture purchases had not taken place. The size of the fireplace was chosen as the design team was valuing the views and connection to nature as being the focal point of the space, rather than a more majestic fireplace element. This would have reduced the windows at eye level when seated and taken away from the feeling of immersion in the forest just outside the windows. That was our decision making process. Either are valid, the team just has to pick which is of higher value for the desired effect. Thanks for your perspective.
