Meet the Designer

At Kirby & Z, we believe great design goes beyond beautiful spaces—it’s about creating a home that supports how you live now and adapts to how you’ll live in the future. Founded by principal designer Lilly Powell, our firm brings nearly a decade of experience designing elevated residential and hospitality interiors across Houston, Dallas, and beyond.


Whether we’re renovating a forever home, refreshing a second residence, or designing with aging in place in mind, our mission is simple: to help you love where you live.


We pride ourselves on being a hands-on, highly collaborative team. From the first consultation to the final reveal, we listen closely to your story, style, and goals, then translate them into thoughtful floor plans, curated furnishings, and timeless design details. Every project balances form and function, with careful attention to color, lighting, and texture that reflects your lifestyle and enhances daily living.


While our expertise guides the process, your voice shapes the design. We seamlessly blend cherished pieces you already own with new selections to create interiors that feel fresh, inviting, and authentically yours. The result is a tailored design experience—and a home you’ll love for years to come.
