It’s come to be known as his signature, some say, akin to an artist signing a painting.

But Frank Dittenhafer, II, FAIA, LEED AP, President of Murphy & Dittenhafer Architects, says that’s not why curved walls end up in spaces and buildings he designs.

“If a curved element fits the space, if it engages people visually, tactilely, and experientially in a positive way, then it goes in the design,” he says. “The curved surface has to be part of the successful engagement of the people who will use the space and go beyond just function in a sensory way that helps people connect over time.”

How it got started

Dittenhafer never started out with the idea of incorporating a curved element into many of his buildings.

“I don’t say everything can only be constructed just one way. Often buildings are built at right angles, so there’s a bit of an unexpected nature to a curved wall,” he explains. “It comes from a natural and unscripted design process I bring to projects.”

Still, just to be different or unexpected doesn’t justify the shape.

“I won’t force a curved element. It must be functional in the space,” Dittenhafer insists.

Making service bays into classrooms

One example is the Byrnes Health Education Center in downtown York.

Located in a former auto dealership, Dittenhafer was challenged when moving beyond the front showroom.

“There were service bays where we wanted to put classrooms for teaching about health subjects,” he recalls of this project more than 20 years ago. “The users were going to be children. So, we had to make it fun and engaging so the kids liked to be there.”

The answer was a gently curving orange wall with steel beams flying over it, openings through it for stairs, ramps and doors, and health-related displays.

“That’s how I connected one end of the long linear building with the other,” he says, “and the curved, brightly colored wall became the organizing signature element that worked with the spaces and the programs presented there.”

Form follows function

How a space is used and how people get around in it often leads to the curved element.

“We designed a curved circulation desk at the new Boonsboro library,” Dittenhafer notes. “Visitors can come close to this, but it also allows the limited staff working behind the desk to look in different directions and easily monitor the entire space.”

When someone described some of his curved surfaces as sinuous, Dittenhafer agreed, saying in these cases the best way to get people from point A to point B was not a straight line.

“I do it with a compound curve, following the natural flow of how people walk by these walls.”

The soul of the project

In some cases, the curved shape defines the building, such as at the renovated Lanham Hall on the campus of Prince George’s Community College in Maryland.

“We re-did this three-story building and added an elliptical lecture hall, and we included places around this for students to sit,” Dittenhafer says. “This helped shape a new outdoor courtyard space as well.”

Dittenhafer states bluntly this design took a bad building and made it a destination.

“Students come here now and take selfies,” he marvels.

Dittenhafer followed the desires of the University of Baltimore’s new president in designing a recital hall with a curved form and placing it on the building’s top floor.

“This hall has perfect acoustics, and the site lines are great. The president added the arts and music programs to this urban campus - and we wanted to place these figuratively high,” he says. “The recital hall on the top floor of the new 5 story building celebrates the presence of The Arts and with amazing City views when listening to music or the spoken word.”

It has to be special

While some see the curved element as Dittenhafer’s signature, he doesn’t, saying it comes from the fundamental creative process of making the space both unique and special.

“People associate this curved element with me, but it has to serve the people who will use that building or space,” he says. “I focus on how people circulate through the area, where the curved wall leads, or what is in the curved walls – and what is it connecting?. It’s more than just the form.”

“If the curved wall makes the space softer or more sinuous or gives it an organic shape and less orthogonal form, then people connect with it,” he says, emphasizing again why he includes this design element.

Dittenhafer wants his curved shapes to be noticed, to stand out as unique and special. That’s why you’ll only see one “curved wall” (or shape) in a Dittenhafer design.

“Everything can’t be unique or special,” he says, “because then nothing is.”
