Who we are

Lotly is a design-driven architectural atelier based in the Bay Area, California. We believe that the best designs come from truly listening to our clients’ needs, understanding their expectations, and delivering thoughtful solutions rooted in over 15 years of architectural experience. Surrounded by the beauty of the California landscape, we draw inspiration to create warm, welcoming, and timeless spaces that feel like a personal retreat.

Our founder and principal, Li Yang, is a licensed architect and graduate of Columbia University. Before establishing Lotly, she practiced at the world-renowned firm Skidmore, Owings & Merrill (SOM), where she contributed to landmark projects such as the Waldorf Astoria in New York City, Penn Station in NYC, and Seattle International Airport. With experience spanning residential, transportation, and commercial design, Li brings a breadth of knowledge and expertise. Today, she focuses on residential architecture, working closely with each client to bring their vision of a dream home to life with creativity, precision, and care.

What we do

At Lotly, we provide comprehensive design services across architecture, interiors, and landscape. Our work ranges from thoughtful remodels to full-scale new construction, always tailored to meet the evolving needs of our clients. Whether it’s reimagining a home for modern living, designing additions or ADUs to accommodate family growth, or creating entirely new residences, we bring a collaborative and detail-oriented approach to every project. Our goal is simple: to help clients build not just houses, but homes—spaces that reflect their lives, aspirations, and sense of belonging.

How we work

Every home is unique, and so is every client’s journey. At Lotly, we approach each project with curiosity, sensitivity, and professionalism. We listen deeply, explore possibilities, and guide clients through the design process with clarity and care. We balance creativity with pragmatism—considering not only design aspirations but also budget, timeline, and long-term value. Our process is rooted in partnership: we design with our clients, not just for them. By combining their vision with our expertise, we create spaces that are not only functional and beautiful, but also deeply personal—places that clients are proud to call home.
