We liked the simplicity and the aesthetics of this solution. The overall addition was the most in keeping with the existing structure, and would seem to be the most doable. we also liked the table/island idea, which seems like it would be highly funtional, and the butlers pantry and mud/laundry room were appealing. on the downside it did not do much to improve functionallity of the second floor space. this was very close to first place, and a negative was that only limited graphics were provided to aid in visualization and fully understanding the plans.
i like the way this blends into the house better. the arc 301 and this are my favorites, the other one is 2 stories but i like this pantry and mud room (but it would be just a laundry room and not a mud room unless therewas a door to the outside)
