HDA

It starts with a vision.

More than just a motto, this is the philosophy that first formed HDA and has continued to support its transformation into a nationally recognized architectural, interiors and master planning firm. Since 1986, HDA has executed creative and timeless design with exceptional customer service, resulting in over 100 million square feet of dynamic space in 44 states at a construction value over $3 billio

n. The firm specializes in a variety of markets including beverage wholesaler, industrial/distribution, adaptive reuse, office/commercial, auto dealerships, multi-family, mixed-use, hospitality, retail, entertainment and craft brewery projects.

Every firm has an origin story. HDA’s is one built on relationships, a willingness to take a chance and a whole lot of hustle.

For nearly 40 years, Jack Holleran has helped shape HDA from a two-person operation into the firm it is today. And while the tools, projects and team have evolved considerably since 1986, the approach to doing business hasn’t changed much: build strong relationships, do good work and never underestimate where one opportunity can lead.

We’re kicking off our new Meet the Minds series with the person who helped start it all.

Hear from Jack on HDA’s earliest days—and the piece of office technology that once felt like a very big investment.

Pat Holleran, Senior Principal at HDA, is headed to Orlando for the 89th Annual NBWA Convention & Product Showcase, October 11–14.

With nearly 2,000 distributors, suppliers, vendors and retail leaders coming together, the NBWA Annual Convention is one of the biggest opportunities of the year to connect with the people shaping the future of beer and beverage distribution.

For HDA, staying close to the industry means more than understanding where it is today—it means listening, learning and anticipating what distributors will need next.

If you’ll be at NBWA, keep an eye out for Pat. He’d love to connect, talk shop and hear what’s ahead for your operation.

This week’s What I Learned This Week comes from Joe DiMartino—and it’s a good reminder that architecture involves a whole lot more than what happens in Revit.

Joe spent more time in the code book than behind the drawing board this week, digging into the rules, requirements, and limitations that determine what can actually be built before design really begins.

And his second lesson of the week? Structural glass is exactly as expensive as it sounds. 😅

Sometimes the biggest part of designing a building happens before you draw a single line.

This week’s What I Learned This Week comes from Kent Wagster—and it’s proof that sometimes the most interesting things we learn have absolutely nothing to do with architecture.

Did you know Hawaii moves about 3–4 inches closer to Alaska every year as the Pacific Plate shifts northwest?

At that rate, they’ll be neighbors in… well, definitely not our lifetime.

Just a little plate tectonics trivia for your week, courtesy of Kent.

It’s always exciting to see how a piece of St. Louis history can take on new life. What was once a bustling retail hub at 6th & Locust — home to a major downtown department store back in 1957 — has transformed into something completely different, yet still full of energy and connection.

HDA had the honor of designing ANEW Rooftop, a stunning indoor-outdoor event space perched atop the Big Brothers Big Sisters of Eastern Missouri building at 519 N. Grand Blvd. With 4,250 SF of rooftop views and 2,250 SF of indoor dining space, it’s a modern, flexible venue designed to bring people together right in the heart of the Grand Center Arts District.

From rendering to reality.

ADB Companies’ corporate headquarters in Pacific, Missouri was designed to make an impact from the moment you arrive.

The bold exterior sets the tone for the 36,852-square-foot headquarters, creating a modern, industrial presence that reflects ADB’s brand and culture before you even step inside.

Another vision brought to life by HDA.

You never know what a simple question might teach you.

For this week’s What I Learned This Week, Senior Project Manager Colleen Nigro took a deeper dive into the history behind our city’s namesake—and discovered there was much more to Saint Louis than his title as King of France.

From his commitment to serving those in need to reforms that helped shape ideas of justice still recognized today, it’s a reminder that there’s always more to learn about the history around us.

Thanks for sharing what you learned this week, Colleen!

Every great design starts with a great idea... and sometimes, a great book!

In honor of National Book Lovers Day, we asked the HDA team to share the books they can't put down (or keep coming back to).

Which one have you read? And what book would you add to our list? 👇

Architecture isn't just about buildings. It's about creating spaces where businesses grow, employees thrive, and communities are strengthened.

Every project starts with a conversation—understanding goals, solving challenges, and designing with purpose.

Whether it's an industrial facility, workplace, multifamily community, or hospitality destination, thoughtful design makes a lasting impact long after construction is complete.

What project are you planning next? Let's talk about it.
