Los Angeles has spent generations obsessed with the myth of the single-family home. For decades, the local dream meant a private patch of grass, a stucco box, and a two-car garage. If you wanted density, you usually got stuck with drab, uninspired apartment blocks that ignored the street and isolated the people inside. Lorcan O'Herlihy spent his career obliterating that exact mindset.
The Irish-born architect, who founded Lorcan O'Herlihy Architects (LOHA) in 1994, died on June 14, 2026, at age 66 after a battle with glioblastoma. He left behind a city fundamentally altered by his conviction that architecture is a social act. At a time when developers treated affordable and supportive housing as mere math problems, O'Herlihy treated them as fine art. He looked at awkward, leftover urban lots and saw opportunities for vibrant communal spaces. Read more on a similar subject: this related article.
Understanding his legacy means recognizing how he forced a notoriously car-centric metropolis to face its housing crisis without losing its soul. He showed that high-density living could be human, beautiful, and deeply dignified.
The Rejection of the Stucco Box
Most multifamily development in Southern California follows a predictable, cheap script. Developers maximize square footage by building right up to the property line, creating dark interior hallways and sterile facades. O'Herlihy took the opposite approach by carving out the center of his buildings. Further journalism by USA Today delves into similar perspectives on the subject.
By resurrecting and modernizing the classic Southern California courtyard apartment, LOHA projects brought light, air, and human interaction back to the forefront. He carved out voids, sliced through massive structures with outdoor staircases, and used bold exterior corridors instead of indoor hallways.
Consider Habitat825, built right next to the historic Schindler House in West Hollywood. Instead of competing with the landmark neighbor, O'Herlihy created a structure that bends and pulls back, creating open space that respects the architectural history while providing 19 dense residential units. He didn't just build housing. He built neighborhoods within single lots.
Elevating Supportive and Affordable Housing
The true measure of O'Herlihy's impact lies in his refusal to treat affordable housing as a secondary, budget-stripped tier of design. He believed that the people who need housing the most deserve the highest quality of design.
In projects like MLK1101 Supportive Housing in Exposition Park, which serves formerly homeless individuals and families, LOHA incorporated sustainable strategies, striking architectural forms, and generous shared spaces. There are no dark, institutional corridors here. Instead, residents move through sunlit outdoor paths and gather in a community room or elevated courtyard.
The design restores dignity to its residents. It actively aids their transition into stability by creating spaces where people actually want to gather. The same ethos drove Isla Intersections, an innovative supportive housing complex built from repurposed shipping containers on a triangular, leftover lot near the intersection of the 110 and 105 freeways. Where others saw an uninhabitable slice of transit infrastructure, O'Herlihy saw a community.
Artistry on Challenging Sites
O'Herlihy never needed a perfect, sprawling canvas to make great architecture. In fact, he seemed to thrive on the tight, awkward slots that other designers avoided. His work proved that constraint breeds invention.
Formosa 1140
Located in West Hollywood, this project is hard to miss with its vibrant, deep red metal skin. O'Herlihy didn't just build to the edge of the lot. He pushed the building to one side, using a significant portion of the private property to create a public pocket park for the entire neighborhood. It was a radical move that directly challenged standard real estate logic.
Mariposa 1038
In the dense urban fabric of Koreatown, this building features a distinct, curving facade that pulls away from the street at its center. This simple formal gesture creates a pocket of public space at the ground level while offering shifting angles and balconies for the residents above. It transforms a standard apartment block into a kinetic sculpture that engages the sidewalk.
From Dublin to the Louvre and Back to LA
O'Herlihy's unique perspective on urban density came from a nomadic childhood. Born in Dublin in 1959, he spent his youth traveling across European cities with his family. His father, the Oscar-nominated actor Dan O'Herlihy, had also trained as an architect. This early immersion in dense, walkable European capitals with active public squares shaped Lorcan's lifelong fixation on public space.
Before anchoring his practice in Los Angeles, O'Herlihy built a formidable pedigree working for legendary firms. He worked with Kevin Roche, spent time with I.M. Pei & Partners where he worked on the Grand Louvre Museum Pyramid in Paris, and collaborated with Steven Holl. These experiences gave him a flawless technical foundation, but his heart remained tied to the messy social reality of housing.
When he returned to Los Angeles to establish LOHA, he brought that European sensibility with him. He realized that a city cannot survive on single-family sprawl forever. Instead of fighting density, he decided to show Los Angeles how to do it right.
Redefining the Future of Urban Architecture
O'Herlihy's passing leaves a massive void in the architectural community, but his firm is built to endure. Earlier in 2026, LOHA transitioned to a collective ownership structure, ensuring that the collaborative, experimental culture O'Herlihy championed will carry forward.
His career earned him the highest accolades in the field, including the AIA Los Angeles Gold Medal and the AIA California Maybeck Award. Yet his real monument isn't a trophy. It is the collection of bright, open, courageous buildings scattered across Los Angeles and beyond.
If you want to understand where urban housing needs to go next, stop looking at theoretical spreadsheets and look at the actual buildings O'Herlihy left behind. Walk past the bright red metal of Formosa, look up at the courtyards of MLK1101, and see how a building can open its arms to the street. The era of the isolated stucco box is over, and we have Lorcan O'Herlihy to thank for showing us the way out.
