Welcome to Jaclyn Mulcahey Design, a full-service interior design firm that prioritizes a timeless design aesthetic that feels authentic, harmonious, and understated. Our goal is to create spaces that feel alive both now and in the future.

We specialize in expert home design, project management, and renovation services—from floor plan creation to lighting design, selection of high-quality hard finishes, paint choices, and curated heirloom-quality furniture selection.

With extensive experience in historic home renovation, we bring an in-depth understanding of building codes and a keen appreciation for architectural integrity. We honor each home’s original character by carefully integrating modern updates while maintaining respectful stewardship. Our network of trusted vendors and tradespeople—including skilled wallpaper specialists, experienced architects, and general contractors—enables us to execute every project with meticulous quality and service. We embrace natural stone, abundant sunlight, quality faucets, and rich patinas, and we recognize the transformative power of well-considered lighting.

At the start of each project, we assess the elements that can and should remain, balancing this with a careful eye to new additions. While we love mixing old with new and welcome the juxtaposition, timeless design is our guiding principle.

Jaclyn has experimented with numerous ideas, drawing inspiration from the places she has called home. Her design aesthetic reflects influences from her time in Los Angeles and her current residence in Evanston, Illinois. Both locations are filled with architecture and design that exude immense inspiration, ranging from Spanish Revival and mid-century modern homes to Tudor Revivals and Italianate Victorians.

Every design project begins with a solid foundation: a Consultation. During this essential two-hour working meeting, Jaclyn will answer detailed questions, develop an initial scope of work, discuss your budget expectations, and initiate the next steps. The goal of this consultation is to leave you with an immense amount of valuable knowledge, and it will be followed up with a detailed email. The cost of the consultation is $350.
