about us

A student of PassiveSolar since the '70's, then pioneering Advanced GreenBuilding in NC daily since '93, we've specialized in constructing some of the most energy-efficient and sustainable homes on the planet. 


As trailblazing trendsetters, we built the first 3 Certified Passive Houses in NC and many more "Passive-ish” homes since.

Educated in the mountains, originally founded in the salty, sunny, harsh, humid, hurricane-prone coastal environment of  NC, we learned the importance of micro-focusing on stout, sturdy, weatherproof, hurricane-strong, low-maintenance green-building techniques, while integrating super-efficient comfort systems.


In 30+ years in the industry, we respectfully seek out and treasure the most key element in the equation - the magically motivating reciprocity of working with fun, happy, thankful clients.

Talk with us, you’ll see!

Chris Senior (Contractor, BA, MA: Anthropology-Archaeology) has been a real estate broker since 1978 & in 1993 began amassing records & firsts in advanced GreenBuilding in North Carolina through constant education & by developing a holistic view of construction.“it's best to view the whole house structure as a system that’s in rhythm with the earth’s calibrated seasonal swaying to and fro,” he says, “not as a collection of unrelated disparate parts.”

Pioneering advanced GreenBuilding in NC daily since '93, we've specialized in constructing some of the most energy-efficient and sustainable homes on the planet. The most advanced certified building efficiency standard in the world is named “PassiveHouse”. They are High-Performance, Low Maintenance, SuperInsulated, extremely Comfortable, Quiet, Oxygenated, strikingly Beautiful Homes. Always trailblazing trendsetters, we built the first 3 Certified PassiveHouses in NC and many more "Passive-ish” homes since.

"Happy Ballplayers Hit Home Runs" & "the Most for the Least": Our process is client-focused and is quite different from typical builder/client relationships. First, as the drawings begin with you and your architect - in that planning phase, we can assist with free advice, in a few gratis meetings, by helping to value-engineer construction possibilities with the design.  It's so beneficial & economical to work this way as a team, early-on, determining the very best construction methods and most sensible materials for your new home. This deliberate planning can make your entire home functional and all its' spaces useful.

A PassiveHouse builder in North Carolina designs homes that look traditional, with a forward-thinking energy strategy.

By Amy Albert

Builder Chris Senior has been fanatic about renewable energy for as long as he can remember. The owner of Anchorage Building Corporation, based in North Carolina, says that his energy obsession morphed into a fascination with “aggressive solar orientation” back in college. An archaeology student, Senior went on digs everywhere from the Midwest to the Middle East. One day came an epiphany. “I realized there’s no prehistoric site on the earth that’s not oriented toward the equator,” he says. “But somehow that primary concern for habitation got lost in things like cul-de-sac developments.”  read more...

Homebuilder Chris Senior wants to leave a legacy by creating homes of beauty and super-efficiency that will last for centuries. He’s steering his company, Anchorage Building, toward specializing in homes that meet Passivhaus energy-efficiency requirements and use a fraction of the heating and cooling energy of conventionally built U.S. homes.  read more...


Passive Makes Perfect in North Carolina

When we first profiled Anchorage Builders in 2010, they were in the construction phase of North Carolina’s first PassiveHouse.  We followed up with the project in a subsequent post and were quite impressed with the completed home, both aesthetically and sustainably.  Building on this successful experience, Anchorage and an architect have recently collaborated on yet another Chapel Hill home designed with Passive House building methods. read more...

First PassiveHouse in North Carolina

This home is officially the first PassiveHouse in North Carolina.  It’s also the first PassiveHouse in the country built out of concrete, according to Chris Senior, certified PassiveHouse consultant and owner of Anchorage Building Corp., the builder.  Senior said his company was able to keep construction costs “surprisingly reasonable” by fashioning the entire exterior from concrete. read more...
