About | TEA2 Architects
Hello. We're TEA2.

We’re a residential architecture firm located in historic Fire Station 28 in Linden Hills — a vibrant southwest Minneapolis neighborhood. Originally known as TEA — Tom Ellison Architects — we’re the second generation of one of the oldest, most experienced residential firms in Minnesota. Since our start 42 years ago, our focus has been on the creation of custom homes and renovations: exquisitely designed, thoroughly detailed, beautifully livable custom homes and renovations.

We’ve created sought-after homes for clients across North America, with projects in Minnesota, Wisconsin, Arizona, Alabama, California, Colorado, Connecticut, Idaho, Illinois, Florida, North Carolina, Ohio and British Columbia.

Our team of 21 professionals works collaboratively. Sharing, debate, ongoing refinement, and continued education drive us to elevate our process as individuals and as a team, and cultivate an uncommon level of creative energy that enriches each and every home we create.

If you’ve seen our portfolio of work, you know we don’t have a specific “style”. Instead, we draw inspiration from historical and modern sources, reinterpreting them for modern living, translating our clients’ hopes and dreams into fresh, imaginative and timeless homes.

Our thoughtful, environmentally sensitive and innovative design has become its own hallmark, garnering a great deal of national recognition. But what pleases us even more? Homeowners who are absolutely thrilled with their homes. Homeowners who tell us they appreciate them more and more with each passing year. TEA2 Homeowners.

From a young age, Gerte was captivated by visual art. But she didn’t see herself as a painter or sculptor, and chose architecture to combine her keen interest in the visual with her aptitude for math and science. What fascinates her most about architecture is the experimentation with shape, experience in the space, and narrative behind each building. Gerte holds a Bachelor of Architecture from her home country, Lithuania, and a Master of Architecture from the University of Washington in Seattle. She loves to travel—and whenever she has a chance, she wanders around the city with her film camera, looking for “that shot.”

Lily Engel

Project Team

Growing up, Lily was always attentive to detail, whether perfecting her form for gymnastics or sketching her surroundings. Her awareness of details affecting outcomes made her want to figure out how the elements affect the whole, which led her to study biology. But, missing the creative aspect of her nature, she made a switch to architecture - where both creativity and science are essential.

Lily graduated from the University of Minnesota with a Bachelor of Science in Architecture and minor in biology. Lily's passion for details and how they affect the outcome pushes her to look at every aspect of a project to create intricate and aesthetic designs. And while she no longer practices gymnastics, you may catch her doing a cartwheel as she runs around the Minneapolis Lakes.

As Chloe grew up, she was surrounded by and enjoyed piano, costume design, set design and construction, painting and ceramics. After her parents purchased a home as a fixer-upper, she had the opportunity to observe and work on many woodworking projects with them. Her pursuit of design as a career emerged from this foundation, sparked by a suggestion from her mom: “Maybe you should try architecture." Chloe graduated in 2018 from the University of Minnesota with a Bachelor of Design in Architecture and minors in Landscape Design & Planning and Construction Management. She is interested in architecture not as a singularity, but as it relates to other disciplines—and she seeks to understand the process of building from beginning to end.

Historic Fire Station 28

read profile

The fire station was built during a time when the population of Minneapolis was growing rapidly and the Linden Hills neighborhood was evolving from a remote lakeside community to a fully integrated neighborhood. The station was the second-to-last originally built by the city, and it was the first to be designed solely for motorized equipment. In contrast to horse-drawn rigs which required more space, time and care, motorized trucks were relatively inexpensive and efficient. Motorized fire-fighting trucks reformed the service by expanding territorial coverage and decreasing response time. By 1993, the charming, tucked-away nature of the neighborhood lead the city to relocate the functional fire station to two new locations with better response times.

The original fire station was listed on the National Register of Historic Places by TEA2 and converted into a restaurant and TEA2’s own office. When the city sold the fire station, the neighborhood was tasked with selecting the new owner based on who they felt the best steward of the building would be. TEA2 won out by an overwhelming majority, as the association believed they would best create the best connection for the building to the neighborhood. The fire station still continues to charm neighborhood visitors and residents, as well as clients, and gracefully support the daily activities of TEA2.
