Est. Collective is a boutique residential and commercial design firm based in Los Angeles, founded by Nicole Heininger. Focused on retail, hospitality, and private residence, Est. Collective is a full-service design studio managing projects from Los Angeles to New York.

The firm is rooted in the ideals that both history and nature evoke a sense of emotion and place which satisfy the soul. We find our inspiration in art, architecture, nature, and the past, creating interiors that are often identified as refined, timeless, and sophisticated. A collective approach between designers, architects, clients, and artisans, yields authentic, timeless work that is simultaneously functional, beautiful and relevant. 

With a degree in Interior Architecture and Design, founder Nicole Heininger has an extensive design background holding leadership positions in some of the top architecture and design firms in the country, including Kelly Wearstler in Los Angeles and Roman and Williams in New York. She has produced award-winning designs for fashion brands, notable celebrity residences, professional athletes, and high-profile hotel projects.


Inherent to the work and design process are the ideas of collaborative ideation, respect for both past and present, and rigorous attention to detail. It is this approach that sets the firm apart and leads to the development of innovative experiences that inspire the end-user and exceed the expectations of the client. Each project is unique and deeply influenced by context, thoughtful research, and the passions and aspirations of the client. Timeless minimalism and a refined aesthetic are central to our work, as well as the love of raw and authentic materials. We believe that thoughtful design contributes to wellbeing.
