Architecture, Interiors & Landscape Design in Irvine

Kyle Prenzlow Architects is an Irvine-based design firm providing architecture, interior design, and landscape design services for residential, mixed-use, and select commercial projects throughout Orange County and Southern California. We work with homeowners, property owners, and business owners on a wide range of project types, including ADUs and JADUs, kitchen and bathroom remodels, home additions, ground-up custom homes, interior renovations, landscape and outdoor living projects, office fit-outs and renovations, retail and boutique storefronts, café and restaurant interiors, medical and dental clinics, and mixed-use small buildings.

Our approach combines thoughtful design, technical expertise, and close collaboration. Every project begins with understanding the client’s goals, the opportunities and constraints of the site or existing building, the applicable permitting and code requirements, and the overall project vision. From there, we develop clear, well-coordinated design solutions that balance aesthetics, function, constructability, and long-term value.

Whether the project involves transforming an existing home, creating a new custom residence, improving a workplace, designing a customer-facing commercial interior, or shaping an outdoor environment, we help guide clients through the design process with creativity, clarity, and attention to detail. Our goal is to create spaces that are beautiful, functional, and tailored to the people who use them.
