Modern-Shed Guest Cottage:
SEATTLE — When Kai Carroll and his wife, Emily Wang, were expecting their second child last year, they knew that they had to create more space in their cozy three-bedroom house in Ballard.
The couple loved their house, and they loved their neighborhood. But with a young son and a daughter on the way, they realized that each child would need their own room — so there would soon be no space for either set of grandparents when they came to visit the little ones.
