Techbuilt Homes
By Grace Shackman and Jeffrey Welch
Techbuilt homes were designed by New England architect Carl Koch to help alleviate the post WWII housing shortage by developing a way to quickly and easily assemble them using pre-made components. The parts were interchangeable to give the buyer a house that met their needs and taste and that worked for the specific site.
Carl Koch
Techbuilt houses offered an attractive two-level interior arrangement in which the lower level functioned as a quasi-basement and the upper level as a quasi-attic but with no loss of functional space. The gentle gable and open area overhead gave to the upper level a cathedral ceiling while the lower level, set in three feet below ground level, allowed the use of every square inch of floor space. In a bow to Michigan winters several Techbuilts were clad in brick.
These houses were scattered around town, wherever clients found an empty lot. Techbuilts were manufactured in Massachusetts and delivered in two truckloads containing basic parts, such as pre-cut beams, wall panels (with or without windows) insulated with fiberglass, and sliding glass doors. Different from other prefab houses, Techbuilts had 4′ wide wall panels, giving buyers many options for placing windows and doors.
Siting was determined by the contours of the land. If the site was on hilly terrain, part of the first floor might be underground but part might provide a walk out. If the house was built on a busy street, a solid wall of windowless panels would be put on the street side, but if on a wooded lot, the windows could be put wherever was the best view.
Because of the post and beam construction, the interior space dividers didn’t need to be load-bearing and thus could be put anywhere to create rooms. The houses were rectangular in shape, typically 24′ x 48′, which made it easier to add on rooms as families grew or wanted extras like a sunroom or a screen porch.
Carl Koch, a native of Milwaukee, attended at Harvard College and continued his studies at Harvard’s Graduate School of Design, receiving an MA in 1937. It was just at this time that Dean Joseph Hudnut brought German modernist Walter Gropius onto the faculty of the HGSD. While traveling in Europe on a fellowship, Koch spent six months studying with the Swedish modernist architect Sven Markelius. This was a formative experience. On his return to the United States, while teaching architecture at MIT, he became involved in developing several housing projects around Boston, which furthered his interest in prefabricated houses. When he was invited to redesign the prefabricated, metal Lustron House in 1949, for example, he reduced the construction kit of 3,000 parts to just 37 components, and he reduced the weight of the kit by 6,000 pounds. By 1952, he had designed the housing development, Conantum, located in Concord, MA, one of the nation’s first cluster housing developments. The idea for Techbuilt emerged from Conantum, particularly from a design by architect Leon Lipshutz.
In 1953 he started Techbuilt, using as his basic premise the elimination of wasteful attic and basement spaces. In its original conception, the Techbuilt house was shrunk to just two floors, whose entire area would be open living space. The lower floor was built three feet in the ground, leaving the other five feet to let in light. Upstairs, the roof above the living space was gently pitched, which gave the house a softer, more Japanese look and allowed for taller windows that made the space seem bigger and airy. Large windows and sliding doors opened up the gable ends. The mid-level entrance on the side of the house gave easy access to both floors.
In 1955 Techbuilt launched its Space Making Furniture Line. Twenty pieces of furniture were advertised for their flexibility, affordability, and customization but they were never a money maker. They came unassembled, much like Ikea kits today.
Ann Arbor Techbuilt Homes
A2Modern has identified 15 Techbuilt homes in the Ann Arbor area but there are probably more. They were built between 1955-1974. In 1955, James Livingston, a graduate of the University of Michigan school of Architecture, secured the Techbuilt franchise for the Ann Arbor area, three years after earning his architectural degree. With his associate, Bob Chance, he built Techbuilt homes for the next three years.
Bob Chance explained that Livingston was the salesman, helping clients figure out which model would work for them and how to site the house. Because prefabricated houses went against the Frank Lloyd Wright dictum of letting the landscape determine the shape of the house, siting was a crucial concern. The on-site architect was essential for guiding the client as to orienting and landscaping the building. Chance acted as the project manager, figuring out the details, overseeing construction, and working closely with Gene Kurtz, local contractor who often partnered with Livingston. Chance thought that Techbuilt was both “an interesting concept and a good deal financially.”
As of 2022, only one Techbuilt, on Heather Way, had been torn down, while the other identified houses were still standing and in good use. In most cases, the Techbuilts are newer than their neighboring houses, but mature vegetation helps them fit in.
Below is an alphabetical list by street address of Techbuilt houses that have, so far, been identified. If anyone knows of others, or knows more about the houses listed, please let us know using the Contact Us form on our website.

Mary and Dick Burris, 1955. This was the first Techbuilt in Michigan and newsworthy enough to rate an article in the Argus Eyes, the Argus Camera employee newsletter. It was different from later ones as the first story was entirely in the ground. The article says it was put together by a local builder, but the Burrises did all the painting and staining, both inside and out. The oven, automatic dishwasher, stove burners, and garbage disposal came with the package. See Old News for the Argus Eyes article of December 1956.

Daniel L. and Margaret Treacy, 1956. Techbuilts appealed to architects. Ann Arbor architect, Daniel Treacy, worked with the local firms of James Livingston and Charles W. Lane, and then he joined the office of Minoru Yamasaki in Troy.
1300 Chalmers Drive, 1955. The fourth owners, Jesse and Anitra Gordon, made four additions, including a sunroom and a balcony, that go perfectly with the original house. Jesse especially appreciated the many windows that allowed him to see the woodsy landscape whichever way he looked.

George N. May, 1958. George May worked as a draftsman at Ford Motor Company. This house, built across the street from Pattengill School on a corner lot, elegantly negotiates a high traffic area and a widening street that leads to the school’s student drop off.
2831 Daleview Drive, Val and Paul Rasmussen, 1974. Paul Rasmussen was Professor of Chemistry at the University of Michigan. “It was a great house to live in, lots of glass, tall ceilings, great views in all directions,” recalls Val Rasmussen of her house, which is the last, or almost the last Techbuilt built locally. Beyond framing, the electrical, plumbing, and heating systems were also designed and done on site as were the interior walls. The Rasmussens ordered Techbuilt kitchen cabinets, which Val says had “great-wooden doors, tall enough to go along the high ceiling. The materials were excellent.” They lived there 35 years before moving to a one-story house.

Alfred and Georgia Conard, 1965. Alfred Conard was a law professor at the University of Michigan and president of the Association of American Law Schools. According to the Ann Arbor News, the exterior of the house was a Techbuilt design and “popular in Ann Arbor since last summer.” The inside was designed by Livingston. The lower level was the living area, and the upper for sleeping. See the story and pictures of the house in Old News.

Irving and Jane Brown, 1956. Irving Brown was an engineer for Detroit Transmission. When later owners, Jim and Linda Elert, founding members of a2modern, moved into this Techbuilt, the original footprint was untouched. It had four bedrooms and a full bath upstairs, mudroom, kitchen, half bath, and living/dining room/fireplace on the first level. The main entrance to the house was on the long side, between the first and second stories. The house was built on a hill, with the living/dining rooms opening to the back yard with sliding glass doors. The Elerts added a porch. The next owners, Katherine and Bob Bodary, turned the two bedrooms at the rear of the house overlooking the backyard into a master bedroom. The next owner added an enormous two-story addition adjacent to the front entrance.

Professor Edwin H. Sonnecken, 1956. Sonnecken was a programming manager for the Ford Motor Company. The fourth owner, Doug Kelley, lived there for 40 years. He appreciated all the windows that allowed him to enjoy nature in every direction on his one -acre piece of land. He added a front patio, a garage, and a sunroom in the back. He was sad when mobility issues made it necessary to move to a one-story place.
