Before: Architect Susan Nwankpa Gillespie of Nwankpa Design gently expanded this 1924 storybook-style cottage in L.A. by 400 square feet by pushing the walls out on all sides and reorganizing the floor plan. The kitchen was a narrow galley separated from the rest of the living spaces with a vestibule that contained the refrigerator, the laundry, and a door to the yard.
