When Place Matters, Local Matters
In a community as distinctive as Pasadena and Altadena, the value of local expertise can’t be overstated. Architecture is never just about buildings—it’s about people, legacy, culture, and context. Whether a project calls for subtle revitalization or a ground-up reimagining, hiring a local architecture firm ensures your design resonates with the place it inhabits.
For the past 24 years, ONYX Architects has been doing just that. As a Pasadena-based studio, we’ve been honored to contribute to the civic and cultural fabric of our region—from the Pasadena Hotel & Pool to the Pasadena Civic Auditorium, Farnsworth Park to La Casita del Arroyo. We know this place because it’s home.
We Know the Landscape—Literally and Bureaucratically
Designing in Pasadena and Altadena requires more than creativity, it requires fluency in a layered regulatory environment. At ONYX, we have deep expertise navigating the local zoning codes, historic preservation overlays, and design review processes unique to our region.
Take Pasadena’s “City of Gardens” ordinance, for example. Our Madison Courtyard project was designed to meet this standard, balancing density with green space in a way that feels inherently Pasadena.

We’ve spent years learning how to design within the architectural language of this region—from Spanish Colonial Revival to Craftsman to Mid-Century Modern—and we work closely with city staff, design commissioners, and trusted consultants to bring those designs to life.
Our long-standing relationships with the City of Pasadena's Economic Development Department and other civic bodies help streamline complex approvals and keep projects moving forward.
Context Is Everything
In Pasadena and Altadena, context isn’t just a consideration, it’s a commitment. We design buildings that feel timeless, approachable, and community-focused because that’s what resonates here.
Our projects are rooted in the idea that beauty and utility should coexist. Whether designing for a public-facing venue or a deeply personal event space, we believe architecture should adapt to its users and surroundings with grace. At Marv’s Place, our well-known affordable housing project, we balanced elegance with function, delivering a building that serves its residents while enhancing the character of the neighborhood.
We understand that every project is an extension of the community it serves, and we take that responsibility seriously.
Trusted By the Community
ONYX is part of the local ecosystem. Our studio is woven into the fabric of Pasadena and Altadena, and our clients trust us because they know we’re invested in elevating the built environment in our own backyard.
Our partnerships speak for themselves. We’ve collaborated with non-profits like Pasadena Heritage and civic agencies dedicated to historic preservation and cultural continuity. We’ve worked hand-in-hand with local developers, public agencies, and community groups to ensure every design contributes to a stronger, more connected place.
There’s No Substitute for Local Expertise
If your project is based in Pasadena or Altadena, having a local partner makes all the difference. With over two decades of experience, ONYX offers deep-rooted relationships, regional insight, and a proven track record of delivering projects that don’t just get built—but truly thrive.
We’re more than designers—we’re your neighbors. We listen, collaborate, and work with you to create something lasting and meaningful, right here in the community we call home.
