SIERRA SULLIVAN
Founder + Principal Designer
Originating from a background of over 30 years in fashion and a passion for art, travel and photography, Sierra’s love and eye for interior design became a natural progression. Starting with a home remodel at the tender age of 24, she restored her own first home, a historical 1932 Spanish Monterrey style home in San Diego and fell in love with the process. Currently living in Laguna Beach with frequent trips to San Francisco, she serves clients in both places, extending to all of Orange County and beyond. Her passion is creating spaces that are truly unique to clients and families, while also ensuring function and livability.
WHAT IS THE FOURTH HOUSE?
In astrology, the fourth house (out of 12) in a birth chart is known as the House of Home and symbolizes the establishment of roots and the creation of a sanctuary for oneself and their loved ones. It emphasizes the concept of coming home both physically and spiritually, integrating personal identity, family history, and cultural traditions into the domestic space. By encompassing physical structures, real estate, family ties, and individualized self-expression, the Fourth House plays a crucial role in shaping our sense of belonging and becoming a fully realized individual. The design process often involves creating spaces that foster connection, serving as a meeting place for loved ones, and a reflection of our unique selves. Thus, The Fourth House Interiors was born.

“Sierra's aesthetic details are stunning. Her vision transformed the room with beautiful touches like the refinished heirloom coffee table and the strategic painting of the brick walls to enhance the fireplace. The French Mattress Cushion for the long fireplace hearth is truly out of this world, and her guidance on selecting the perfect fabric for it was invaluable. Sierra successfully created a space that perfectly combines form and function, right down to the custom oak storage bench for toys and blankets. Not only is she an incredibly skilled professional, but Sierra is a very kind, calm, and sweet woman, a complete joy to work with. Before hiring her, I reviewed several of her past projects, and though they were quite different from our needs, it was immediately apparent she is capable of creating amazing spaces and satisfying the needs of many types of clients. We absolutely highly recommend her!”
