Lily Collins has sold the iconic Case Study House #10 in Pasadena for $6.13 million. Designed in 1947 by Kemper Nomland and Kemper Nomland Jr., the mid-century modern residence is part of the legendary Case Study Houses program.
Collins purchased the home three years ago from comedian Kristen Wiig for $3.9 million. The new owners now hold not just a home, but a rare piece of architectural history.
Case Study House #10 remains a timeless example of innovative post-war design and continues to influence modern architecture in Pasadena and beyond.
Mid-Century Modern Elegance in Pasadena
Case Study House #10 showcases the defining elements of mid-century modern design, from its bold flat roofline to expansive glass walls that blur the line between indoors and out. The open layout and minimalist form emphasize a harmony of simplicity and function, creating fluid transitions throughout the space.
Original details such as concrete block walls and post-and-beam construction remain intact, preserving the home’s architectural authenticity. Generous windows frame serene views, highlighting the architects’ intention to integrate the natural landscape with everyday living.
Thoughtful materials, including warm wood accents and era-specific fixtures, enhance the home’s timeless feel. The interiors offer a clean, adaptable backdrop for both vintage touches and contemporary style, staying true to the mid-century ethos.
From Wiig to Collins: A Celebrity Legacy
Before Lily Collins, the home was owned by actress Kristen Wiig, who brought renewed attention to the historic 3,425-square-foot residence. Her 2020 sale of the property marked a new chapter, one that Collins embraced with admiration for its heritage and striking design.
Though her stay was brief, Collins’s ownership attracted architectural enthusiasts and media alike, amplifying the home’s cultural relevance. The transition from Wiig to Collins illustrates the enduring allure of Case Study House #10 among Hollywood tastemakers.
Their stewardship reflects a broader legacy—preserving architectural significance through refined, modern living in one of Pasadena’s most historic homes.
A Scandinavian-Californian Transformation
During her time at Case Study House #10, Lily Collins introduced a subtle yet impactful blend of Scandinavian and Californian design, carefully preserving the home’s mid-century modern foundation. She embraced neutral color palettes, soft textures, and clean lines, allowing the natural light and open architecture to take center stage.
The combination of Scandinavian simplicity and California ease brought a modern warmth to the residence. Minimalist furnishings and natural wood tones complemented the original concrete and glass structure, creating a seamless fusion of past and present.
These thoughtful updates elevated the home’s appeal for today’s design-savvy buyers—those who value architectural heritage but seek contemporary comfort. Collins’s vision ensured that Case Study House #10 remains both historically important and stylistically relevant.
