As an architect, I'm trained to consider aesthetics when designing a home or remodel. By paying for good design upfront, you can avoid design mistakes that cost a lot of money to fix later.
In this case, even without the addition, better placement and design of the windows and front entry would have made this home much more attractive. The owners would have been spared many years of living in a home they really didn't like.
After corrective design work, the owners are now happy with their home. Very happy.
