Begin with the occupants and the architecture

The Upper East Side apartment in the source belongs to owners who moved from San Francisco and wanted a more relaxed West Coast character. Pembrooke and Ives worked within a pre-war Manhattan setting instead of treating that background as an obstacle. Traditional details and vintage pieces remain part of the arrangement, while the new design introduces a more casual, welcoming atmosphere suited to the household.

Use material and color to link the influences

Warm wood, ivory, and blush provide a softer foundation for stronger jewel tones. Midcentury references appear alongside more classical features, while glass and metal partitions offer flexibility between spaces. The result depends on relationships among the pieces rather than dividing the room into competing styles. When mixing influences, identify a shared palette and useful layout first, then let furniture from different traditions contribute their own character within that framework.
