Creating either a traditional design or a modern one is straightforward. Creating a space that marries the two styles can lead to a design divorce. If done incorrectly, the outcome can be awkward — but if done with care, the results can be truly amazing. I put this principle to work during a recent project for clients Anne and Jeff, who had a large ground-floor living room with a large problem. The room was packed with mismatched furniture and jarring styles: chic sofas rubbed elbows with ornate chairs, modern artwork hung alongside antique paintings.

Unsure how to make it all gel, Anne and Jeff asked if I could help them unify their old and new pieces and turn the discordant room into a harmonious space.
