For Edward and Sally Yedid, designing a home was an essential part of building their relationship.

​In May 2015, when they happened to meet at a friend’s dinner party in Paris, he was a partner at the architecture and design firm Grade and was living in New York, and she was working as a product designer in London.

​“We sat next to each other,” said Ms. Yedid, 32, and discovered a shared passion for art and design. “That was that.”

They quickly found themselves in a delirious long-distance relationship, continually crossing the Atlantic to visit each other. “It was a lot of air miles,” Ms. Yedid said.
