Nicole Alexander's journey into the world of design began at an early age, profoundly shaping her creative outlook. She recounts, "My upbringing included frequent visits to estate sales and auctions with my parents, and our home was always adorned with extraordinary discoveries." This early immersion cultivated a deep appreciation for unique aesthetics and the stories objects could tell.
Before dedicating her career to interior design, Alexander explored various artistic avenues, including art therapy and dance. Her entrepreneurial spirit led her to establish Mr. Lulu, a fashion line where she crafted distinctive garments from vintage and repurposed materials. This hands-on experience later transitioned into custom furniture creation, a pursuit that continues to underpin her meticulous understanding of craftsmanship and the tactile qualities of materials.

In 2006, Alexander founded Siren Betty, her Chicago-based design studio. The firm is celebrated for its inventive approach to hospitality and commercial spaces, with a portfolio spanning acclaimed restaurants, boutique hotels, and innovative adaptive reuse projects. Each endeavor reflects a harmonious blend of the client's vision and an immersive guest experience.
Alexander's work with Siren Betty exemplifies a thoughtful and layered approach to interior design, creating spaces that resonate with character and purpose. Her projects, as highlighted below, showcase her ability to imbue each environment with a distinct personality and an inviting atmosphere. These five diverse designs illustrate her commitment to functionality, nostalgia, and a touch of whimsy.
Five Distinctive Projects by Siren Betty Design
The firm’s projects demonstrate a versatile design philosophy, beginning with Layla & Ringo's. This Chicago coffee shop, part of a larger multi-concept venue, was designed to accommodate a dynamic daily flow. Alexander focused on providing abundant natural light, comfortable seating, and various counter heights to cater to remote workers and casual visitors alike. The space's adaptability, allowing it to transition from a morning coffee spot to an afternoon workspace and evening social hub, was a key design objective, fostering an environment where guests feel welcome regardless of their reason for visiting.

For Dimmi Dimmi, the design team aimed to evoke the warmth and familiarity of a classic Italian-American restaurant. The space features nostalgic elements like checkerboard floors, rich red leather, and vintage-inspired lighting, balanced with playful details such as soft florals and unique hardware. Alexander emphasizes the importance of layering, incorporating both commissioned art and thrifted pieces to create a sense of history and comfort, making guests feel as if they are returning to a beloved, long-standing establishment.

The Hoffman House project illustrates Siren Betty's selective approach to residential design, prioritizing clients who embrace bold ideas. This home provided an opportunity to use unique fixtures, such as a glass and marble pedestal sink, which would be impractical in a high-traffic commercial setting. The success of this project has encouraged the firm to explore more residential commissions, showcasing their adaptability and creative range beyond commercial spaces.

For El Che Steakhouse + Bar, Alexander collaborated with a long-time associate, Chef John Manion. The design for this live-fire cooking establishment incorporates reflective surfaces like oversized mirrors and metallic light fixtures. These elements create dynamic flashes of light and activity from the open flames, contributing to the restaurant’s dark, moody, yet exciting ambiance. This project showcases Alexander’s ability to integrate design with the functional heart of a venue.

Finally, Double Fun demonstrates a remarkable transformation from a mundane retail bank into a lively bar in Chicago’s Gold Coast. The design team used rich wood, warm lighting, and tactile materials to create a sense of history and character. Architectural features like a curved bar, custom millwork, banquettes, and arched niches add visual interest. The intentional design ensures a welcoming entry from the street and encourages exploration of the space, revealing intimate details and seating areas further inside. This project epitomizes Siren Betty's skill in blending character with approachability for a truly engaging hospitality experience.
