Our teams combine expertise in architecture, engineering and interiors to offer integrated services to our clients’ challenges. Our focus is on buildings that connect communities and enable a rich diversity of experience. Our design approach is based on inquiry, focused on innovation and rooted in social and environmental responsibility.

Today, we continue a legacy of innovation and commitment to client satisfaction. More than 400 design and engineering professionals in twelve studios continue to create exceptional spaces that enhance and enrich the human experience.

In 2025, Southern California-based Delawie joined LEO A DALY, bringing additional expertise and footprint to the firm. Together, we share the same passion for design, collaborative culture and client-first approach.

Our Vision

To transform the human experience through the power of design

Our Mission

To create innovative, thoughtful and sustainable solutions with our clients

  • Modern office lobby with large glass windows overlooking a river, featuring seating areas with chairs and tables, a staircase, and a second-floor balcony with additional seating.

    Our customer first

    We work every day knowing that we exist for our clients.

    Our clients — whether external or internal — give us the opportunity to design and create. Recognizing that helps us choose clients that align with our values and principles.

  • Bright, modern corridor with colorful window panels casting multicolored shadows on the floor, and a man walking toward the distance.

    Innovative by design

    Make design excellence the constant.

    Design excellence is subjective. What isn’t is the need to maximize every design opportunity in everything we do. These small decisions will accumulate, elevating our firm as a competitive design practice.

  • Modern building with large glass windows and metallic panels, with some open metal window shades, under cloudy sky.

    Ethical always

    Insist on the highest moral standards from yourself and others.

    This must be the cornerstone of our firm. At the end of every day, if we can say that everything we did was governed by this principle, we can start the next day.

  • Group of people in a meeting room watching a woman give a presentation on a screen. The table is cluttered with books, papers, and coffee cups. Posters on the wall show building layouts.

    Fair and inclusive

    Respect everyone – appreciate the value in diversity.

    As designers, we understand the value of seeing the world through many different lenses. Our firm, and our work, should reflect the diversity of the communities we serve, and express the genius of that diversity.

  • Modern black building with red accents and a red logo of a stylized figure with horns, set against a dusk sky.

    Responsible

    Own the impact of our work.

    Everything we do impacts the world, both environmentally and socially. Is that impact positive or negative? Are we satisfied by net-zero, or is our work regenerative? We need to understand that impact and keep ourselves accountable always.

  • A spacious modern library with children reading and playing, bookshelves filled with books, large windows, and cozy seating areas.

    Never stop learning

    Bravely explore your curiosities.

    Design is all about exploring possibilities. We want to create the kind of place where you are free to try things that haven’t been done before and aren’t afraid to make mistakes along the way.

  • Empty swimming pool with lounge chairs and umbrellas surrounded by palm trees overlooking the ocean at dusk.

    Make it fun

    Love what you do – celebrate the hard work.

    Our principles are a challenge to uphold, but they promise amazing rewards. When you love what you do, you own the positive impacts of your work, and that’s a cause for celebration

Committed to better

  • Great design (and great business) is rooted in sustainability. Our stakeholders collaborate with us to build spaces that withstand challenges, support the well-being of their occupants, have less of an impact on our environment and maximize energy efficiency with high-performance design.

  • We advocate that our projects, workplace and communities are more diverse, equitable and inclusive. We are accountable to fostering a culture of empathy, increasing opportunities in our industry for underrepresented populations and considering the impacts of our work on marginalized communities.

  • A strong sense of community is the heartbeat of life. We pledge to leave the places where we live and work better than we find them by volunteering our time and talents where they’re needed most.

    Some of the organizations we support:

    • ACE Mentorship Program

    • Second Harvest

    • Big Brothers & Big Sisters of America

    • My Sister’s Place
