Powerhouse creatives
We love creative challenges. We love livable plans. We love bringing a fresh face to Des Moines-area residential building design. We love what we do. And we’ve been doing it since Aller Design Group was launched in 1998.
Design maestros
We grew up in the business and we can do it all. Residential. Commercial. Contemporary. Traditional. We can draw on CAD or on a napkin. But every plan will have one thing in common. It will be inspired.
Laid-back listeners
We’re a flexible group. We work with either builders or homeowners. We discover what you really want, then create classy, clever homes—and positive client relationships—that stand the test of time.

Jim Aller


The classy, classic sense of flow in owner Jim Aller’s home designs might partly stem from his love of rhythm and jazz. He plays drums and collects them. He listens to standards (Sinatra, Miles Davis, Diana Krall) and drummers like Buddy Rich or Benny Greb. He confesses he’s “spent stupid money” on vintage drums, stereos and his audiophile hobby, but points out he still has his first stereo system (a Christmas gift at age 10) and is getting his five children hooked on the joys of retro music. But the sense of rhythm and movement in his designs might also come from his passion for light and livability in a house, and long-time experience making it happen. He grew up in a Des Moines family construction firm. He draws by hand or computer. He attended Iowa State University and spent years with a Leading National Architectural Firm before launching his own design firm. And, whether it’s a client or a vinyl record, he really knows how to listen.

Ted Karnes


Ted Karnes, operations manager, started drawing blueprints before he could drive. His dad owns a construction company and “I started when I was probably 15. I didn’t even have a driver’s license but I was already drawing plans.” Des Moines-born and raised, Ted started studying architecture in high school. He put in a decade of time with Regency Homes and a Leading National Architectural Firm before he and Jim—his cousin—started working together in 1998. As much as he loves designing interiors, he also loves the great outdoors. He’s an avid camper—as long as there is a fan and a fridge. He has golfed since age nine and still hopes that his game will improve. And then there’s baseball. The avid Cardinals fan now mainly watches some of his five kids play, though he gets too nervous to sit. On his bucket list: a tour of national ballparks with his sons. And maybe then he’ll sit down.

Stephany Ireland


Stephany Ireland is one of our job captains, meaning she gets to ask clients about their big ideas and then bring them to life on paper. She loves working on our tight-knit team because, while we work our tails off and come up with some pretty brilliant stuff, we also tend to laugh our heads off at least once (or ten times) a day. Stephany isn’t just great at her job. She’s also a stellar friend and mother of identical twins! And, fun fact, she’s an identical twin herself. When Stephany isn’t sketching houses or other cool buildings, you might find her volunteering for the Des Moines Mothers of Multiples Club. (She’s their National Representative and Advisor—big stuff.) Stephany is also the self-proclaimed World’s Biggest Ranch Dressing & Coffee Fanatic. “When I go to a restaurant, I literally will ask for a gallon of ranch. I’m also a coffee-lovin’ fool! Everything coffee, all the time!” We assume all that caffeine must have something to do with her ability to raise twins while being uber involved in her community and owning it at work every day. So we don’t question it.

Santi Perez


Santi Perez, our Intern Architect, hails from the country of Spain. He grew up in Valladolid and attended the School of Architecture at the University of Valladolid. In 1998, Santi came to the U.S. and settled in Ames, Iowa. He now lives in Grinnell with his wife (a college Spanish professor), and two children. Santi has worked in the architectural field for more than 25 years and has received multiple awards. He was part of the team that designed the music auditorium in Iscar, Valladolid, which won a prize at the state level and received high praise. When Santi isn’t creating stunning designs, you can find him enjoying sweet desserts with his family or attending one of his daughters dance competitions (and maybe even dancing at one). In addition to being a “dance dad” for his daughter, Santi has been a soccer and robotics coach for his son and even joined him in TKD. And he has a green belt to prove it! Out of all of Santi’s accomplishments, he prides himself most with being able to adapt well in the United States despite having no knowledge of the language and culture.

Noah Tornabane


Having been born on the day the Denver Broncos won the Super Bowl, means our intern architect, Noah Tornabane, was destined to be a sports fanatic. We are thankful his dreams of becoming an NBA player didn’t pan out, because we think Noah is an outstanding designer! Before graduating from Iowa State University with a bachelor’s degree in Architecture, Noah interned with AECOM’s Sports Office in KC and was able to incorporate his love of sports into design. He even had the chance to work on a billion-dollar basketball arena for the LA Clippers. We are excited for Noah to add his recreational spirit to our commercial and residential designs. If you are looking to have an indoor basketball court, golf simulator, or theater for watching ESPN – Noah is the perfect designer for the job. During the summer he can be found at the local golf course or at the lake house playing board games with his family. Noah is currently working to gain his Architectural License in the State of Iowa.

Mindy Aller


Mindy Aller may have only one title, office manager, but her tasks are many: bookkeeper, bill juggler, customer service, errand runner… The Des Moines native studied Communications at Iowa State, and in addition to being mom and Chauffeur in Chief for five kids, worked several years as a private investigator specializing in insurance fraud. In 1998, she and husband Jim launched Aller Design Group. But while the firm crafts lofts and living spaces, she might be creating something else. “My mom taught me to knit when I was ten” during one boring, rainy vacation day. She was hooked. It’s her escape, it keeps her hands busy, and bonus: an unspooling stream of socks, afghans, scarves, hats… If you have a question for Aller Design Group, especially with her detective background, she will likely find the answer. And also, if you wish, a cool craft idea to go with it.

Is that heavy metal I hear?

Jim Aller: Yeah, it’s Shea’s turn with the Spotify.

OK, so what is the Aller Design Group?

Jim: Well, we’re not a plan service. I mean, we have tons of plans, and we have people come in all the time for that, but we want to be creative in drawing homes. We want to do something cool, something special each time out, and do it for lots of different people and price ranges. We’re mainly residential but we do commercial too. We work with builders to develop their styles and we work with clients who don’t have a builder yet.

Do you have a signature style?

Ted Karnes: We’re so all over the board. At first people liked traditional stuff but now we’re really getting into a lot of contemporary. Mid-century is really happening here now, like low-pitched roof ideas. It’s really not about the style. It’s more that we’re really at the top of the game when it comes to fresh new designs in Des Moines. With every home you design, no matter the style, it’s like you’re not even doing the same job. It’s unique. Every project is different. We like that.

What makes you different?

Jim: Part of it is our experience. We’ve all had experience on the construction side as well as the design. We are diverse. I worked for a national firm and traveled all over the country. It’s exposure and insights some competitors don’t have.

Ted: We know how homes go together, so our designs work. We even know which product is best to use. Overall, we’re trying to put a fresh look and a fresh face to the design in this town. I think we do this at least as good as anyone.

Jim: Also it’s important to have the right team. We can run the software like everyone else, but we also know how to draw with markers and lay it out right in front of you. And we’re all kind of goofballs. We like to be loose. We’re flexible. But we also really like a challenge. We like being ahead of the curve. And maybe we just do a better job of listening to people. Some of our projects take a long, long time, and that’s OK. We’re comfortable just sitting down with the client and just letting it go from there.

So how do you work with a client?

Jim: We’ll sit down and we might hand-draw right in front of them. Because we can do it. I’m old enough that we weren’t on computers when we started. I was pen and mylar, you know. We do things in phases. Phase 1 we start with simple bubble diagrams just to lay out the flow. It’s very loose, very conceptual. Phase 2 is design development. You start squaring it up, get it a little more rigid, bring in the details. Phase 3 is the construction documents. We make the client part of the process all the way through and never go to the next phase until the client is happy.

Ted: We really want to listen to you. Who you are. How you live. That’s our whole philosophy of design. How do you get up in the morning. What’s your routine. It’s not just the style of home. It’s how a person lives and what activities they’re into and what their kids do. Even the way you clean or organize things. People will go out and look at plans or existing houses and say “OK, I’ll take that one.” They don’t understand how great it can feel to live in a home designed just for the way you live. It feels nice. It helps you function. It makes your life easier. It makes you feel good. It really does. That’s what a house should be.

What else do you try to achieve in your designs? 

Jim: One thing we’re known for is an open plan, a lot of flow. One of the things is to bring a lot of light in so I really do load up with windows. When you walk into a house I want the plan to feel bigger than it is.

Ted: We also don’t have extra rooms you don’t need. The rooms you do want, they’re the size you want them. Even the basement flows the same way as the upstairs. It’s not all choppy because of beams and posts and ductwork in the wrong spot.

Jim: We also keep it simple. The home I design for you is a simple palette and I’m going to let you finish it and furnish it. Why gaudy it all up and add cost to the budget? Why not just give you a nice clean home that lives well and has nice flow, nice materials, and let you decorate it the way you want. And no matter the style, I want it to be timeless. If we can do that, then we’ve succeeded.

Aller Design Group has been doing this since 1998. What do you enjoy about it?

Jim: I enjoy meeting people, having things go well and making friends along the way. I have friends that go way back to elementary school. That’s just the way I am. And I like coming up with ideas to make the project special. Also it’s always rewarding to watch the house go up. It’s like everyone won the game and that is the trophy. The house is the trophy.

Ted: And when we send a plan to a client and all they say is “Wow.” That’s enough. Just that one word. That’s everything.

What’s next for ADG?

Jim: Things are going fast right now, and we’re really cranking it. We may expand. But we don’t need to be the biggest. I love what I do. I’m not really driven by money. I mean, I do appreciate money, but I believe all these things in life were given to me. It’s more about I want to be the best I can be with the skills I’ve been given.

Ted: We’d love to be able to do it on a national level at some point, but we want to be a family-owned community business and earn respect. We want to be known for treating people well. It’s not just about growing. It’s also about doing what you love to do. I can work 60 hours a week and not be tired of coming in to work. You feel like you are part of something.

And you don’t mind coming in to work even if heavy metal is on Spotify?

Ted: Music is a big part of what we do. We’re a close-knit group and we’re laid-back. The whole philosophy is having fun and being loose. That’s where creativity comes from. I will listen to anything but I’m more southern rock: Lynyrd Skynyrd. Stevie Ray Vaughan. Old bluesy rock. Some of the stuff Jim puts on though, oh my gosh, it can be bizarre. But he’s an extreme audiophile.

Jim: I design with music in the background all the time. A few days ago it was screaming metal in here and Ted walks in like, ‘Really? It’s 7:30 in the morning!’ And then last week we had classical loud. Shea put headphones on. He wanted no part of it.

So your musical tastes may be different, but when it comes to creative home design, you all follow the same drummer…

Jim: Yeah, I guess you could say that.
