Our Story

TE Studio is on a Mission

Tim Delhey Eian founded TE Studio in 2008 to offer holistic, performance-based design to clients in North America. At TE Studio, we feel that it is important to create buildings that deliver on many levels of design and performance, and provide real measurable value to our clients.

We are expert designers, dedicated to beautiful, durable, functional, and earth-friendly building designs that offer healthy environments and economy to meet our client’s needs—both now and in the future.

TE Studio/ Intep offices

We practice Passive House design–the world’s leading voluntary building energy standard focusing on superior energy efficiency and quality of life at low operating cost. While originating in Germany, the founders of Passive House were deeply inspired by the energy conservation movement in the U.S. in the 1970s. We feel that the availability of Passive House in the U.S represents a perfect blend of the American spirit of invention combined with German engineering. We adopted this world-class standard as soon as it was commercially available to provide our clients with measurable, leading edge performance and results. We have successfully designed Passive House buildings in one of the most challenging climates on earth. We welcome the opportunity to do the same for you wherever you are.

We are practicing out of the TE Studio/ Intep office in the Northeast Minneapolis Arts District, which we built-out and retrofit with Passive House components in 2014.

Tim Delhey Eian

Tim Delhey Eian

Dipl.-Ing., CPCH (PHIUS), CPD (PHI)

You could say Tim was destined to have a career in architecture. At age three he followed construction progress of his new family home in Germany with fascination. As a young teenager he worked as an intern with his parents’ architect. Already realizing his life’s passion, he further prepared himself by mastering the foundations of woodworking in a carpentry apprenticeship, earning the prestigious title Master Carpenter. He later graduated with honors, earning an architectural engineering degree (Dipl.-Ing.) from the Technical University of Kaiserslautern, Germany.

Tim has over twenty years of experience in both Germany and the U.S. Deeply influenced by exposure to stringent German environmental policies throughout his formative years, he has a strong conviction that protecting the earth for humankind is one of the key challenges of his generation.

With the desire to take residential design to a new level of sustainability, Tim founded TE Studio in 2008. The same year, he started designing the first certified Passive House home in Wisconsin, which is also the first to offer plus-energy levels of performance in the country. In 2009 he joined Stephan Tanner–architect of the first certified Passive House in the U.S.–at Intep, a commercial architecture, engineering, and consulting firm. Tim was a founding board member of the Passive House Alliance U.S.—a nationwide trade organization promoting the Passive House building energy standard. He is a regular visiting lecturer at the University of Minnesota, and many other continuing education venues. He and his wife are raising their two children bilingually in Minneapolis.


Stephan R. Tanner

Registered Architect AIA

Swiss-born American architect Stephan Tanner’s travel-infused upbringing developed his deep understanding of designing for the global community. Today, he is a premier leader in true sustainable architecture here in the US, introducing the Swiss and European standard of efficiency to the American market.

Stephan has 40 years of experience in architecture, which he learned from the ground up as an apprentice in Switzerland. Additionally, he holds an Art degree from the Minneapolis College of Art and Design. Stephan worked for 8 years as a design principal at a renowned Swiss architecture firm before founding Intep North America in 1996. In 2005, he designed North America’s first certified Passive House, the award-winning Waldsee BioHaus environmental learning center—a beacon for high-performance building.

In order to create buildings of the highest efficiency standard, the highest quality materials are needed. Stephan co-founded Peak Building Products with his son Robert to import essentials from Europe.

In 2010, he and Tim Delhey Eian joined forces, first in Intep, and later in TE Studio. In 2015, Stephan co-founded the North American 2,000-Watt Society Institute, an organization that promotes the possibility of consuming only 2,000 Watts of energy per person, per year, in an effort to halt global warming and provide an ultimately sustainable framework for humankind.

People Are Talking

“Tim’s passion for passive house design is unlimited and it is exciting to see him pour that enthusiasm into the design of our new home. Tim has always responded with helpful advice and extensive knowledge to get us to our final goal–a simply beautiful, sustainable, and efficient home designed for our growing family.”

Julie and Tarek Alkatout, Clients


(TE Studio is) “on the local cutting edge of achitectural sustainability with their support of Passive House projects. They are very approachable, friendly and enthusiastic. We are fortunate to have such innovative talents right here in Minnesota!”

Dr. Carol Winter and Dr. Kirk Dornfeld, Clients


“Tim’s greatest talent may lie in his skill at listening, and applying those thoughts to the project. I wholeheartedly recommend Tim’s services, without reservation, for anyone looking to design a house, particularly a Passive House, in our northern climate.”

Dr. Gerald Konkol, Client


“Just got the gas bill – it looks like we heated the house for $33 in January. Looking back at our utility records, and accounting for the fact that we’re heating over twice the previous square footage, I’m coming up with a rough savings estimate of 85-90%. Or, put another way, the house uses 10-15% of the energy it previously did. That’s one mission accomplished.”

Paul Brazelton, Client


“Doing a kitchen remodel without design help is like trying to cross the Pacific without chart or compass. Tim Delhey Eian provided ingenious ideas, practical know-how and insightful advice every step of the way. His schematic was amazingly detailed—and beyond that, he helped make my vague dream a beautiful reality.”

Irene Alder, Client


“Tim is passionate about architecture and the environment.  He has great understanding of construction. He is great to work with and we look forward to more projects with him in the future.”
