Building with sustainability has been at the heart of G. Christianson Construction’s motto for 30 years. Founder, Greg Christianson, passed his passion for the environment on to his son, Carl, who took over his father’s business in 2014. Out of Greg’s appreciation for nature and the planet, he restored six acres of his personal property back to native species, and he built a company that builds energy efficiency into every project.  When it came time for Carl to make a nest for his young family, he chose to build a new home to Passive House standards, and in the process became the first builder in Corvallis to be certified by the Passive House Institute.

Building “green” is a scale that the consumer can decide where they fall on. On one end of the spectrum, installing LED lights over incandescent lights saves energy and waste. On the other side, building Earthships out of 100% recycled materials takes nothing more than has already been produced from the planet. The G. Christianson approach is somewhere in between the two. In building Passive houses, our craftsmen build an extremely air-tight home with a focus on clean air circulation. This means, proper and secure window and door installations, where heating energy does not leak out. This also means building a strong frame and the absence of gaps in the structure. It may raise the question, “Aren’t all houses built alike?” The simple answer is, “No.” A house that pops up in a quick time frame is not going to have the same quality craftsmanship as a house that takes nine to twelve months to build.

The Passive building approach was born out of a desire “to create structures that are durable, resilient, comfortable, healthy, and super energy efficient” [www.phius.org/about/mission-history]. Passive Houses are built in accordance these five building-science principles*:

  • It employs continuous insulation through its entire envelope without any thermal bridging.
  • The building envelope is extremely airtight, preventing infiltration of outside air and loss of conditioned air.
  • It employs high-performance windows (typically triple-paned) and doors
  • It uses some form of balanced heat- and moisture-recovery ventilation and uses a minimal space conditioning system.
  • Solar gain is managed to exploit the sun’s energy for heating purposes and to minimize it in cooling seasons.

Admittedly, the construction industry is slow to initiate change from the status-quo. The consumer should be aware of material and product selections when seeking a cleaner living space. Choose materials like Marmoleum that are made of recycled materials and installed with very low to no-VOC adhesives. Ultimately, businesses provide what the consumer demands. We can all stand to take a more serious look at the future of our planet and ask ourselves, “What are we choosing to invest in,” and “How is that product affecting my health and my family’s wellness?” At G. Christianson Construction, we aren’t striving to build the biggest mansion on the block. Rather, we believe that building small and sustainable is the smarter, eco-conscious solution.

Two members of the G. Christianson Construction team are PHIUS Certified Builders, and another member of our team is a certified Sustainable Home Professional (SHP). For consultations on an energy-efficient home remodel, or inquiries into building a new home, please call our office to set up an appointment.

Many of us in the Willamette Valley have been told the “big one” is coming. Oregon has a 40% chance of a MAJOR seismic event within the next 50 years. While it’s impossible to know when the earthquake or earthquakes will occur, we shouldn’t make the error of assuming we have time to prepare.

Much of Oregon’s infrastructure will not be able to withstand a major seismic event, including many homes. Homes built before 1974 are likely to be particularly vulnerable to structural failure in the event of a major earthquake. Many of the homes built prior to 1974 were not bolted to their foundation during construction. Additionally, only 20 percent of Oregon homes have earthquake insurance.

Here is a checklist (from Simpson StrongTie website) that you can use to determine if your house is connected to your foundation and reinforced to withstand an earthquake.


Picture and list from: http://www.safestronghome.com/earthquake/03.asp

  1. Wood wall around the perimeter of the home are secured to the foundation, using anchors, bolts, sill plate connectors and holdowns.
  2. Metal strap ties or holdowns are used to connect the 2nd floor to the 1st.
  3. Beams and joists are joined together with metal connectors and fasteners (the critical points within the frame of a home are where 2 pieces of framing material meet).
  4. Metal connectors are added to connect the roof to the wall top plate.
  5. Post-to-beam connections are reinforced with metal connectors.
  6. Minor foundation wall cracks are repaired with epoxy.

With the help of a local Structural Engineer you can determine exactly what your home needs.

If you need this type of retrofitting, contact G. Christianson Construction, a licensed contractor, to install the necessary anchors, bolts, connectors and holdowns. 541-754-6326.

Main dining room.

In late August, the Old Spaghetti Factory called us to find out if we could help them remodel the historic rail depot that once held Michael’s Landing and Terminus restaurants. They had an aggressive schedule to open by mid-November and didn’t know any local craftsmen. We offered to help and Old Spaghetti Factory hired us to provide the framing and structural repairs required to reinforce the historic building and bring back its splendor. Cascade Design provided structural engineering and gave direction for replacing a few posts, reinforcing an old timber beam and reinforcing a steel beam.


Upper dining room.

G. Christianson Construction has had our crew of three trim carpenters working at Old Spaghetti Factory for three weeks and expect to finish on schedule. The crew salvaged the old interior trim and re-milled the old vertical grain Douglas fir for reuse.  We are installing new Poplar post wraps, corbels and trim. On the main level we pulled the historic windows, refinished and re-installed them. Next we installed Lauan wainscot paneling, battens, top rail and trim.  After that, we installed built-up trim around the existing windows to mimic the historic trim. We are very excited to help restore an exceptional piece of Corvallis’ history.

Congratulations to Greg’s parents and Carl’s grandparents on their 70th wedding anniversary.

Beth and Wally encouraged Greg to get started with his first construction work when he was in high school, by painting their neighbor’s houses. They are very proud of the company we have built here in Corvallis. Wally’s career in mechanical engineering also inspired Carl to get his degree in Construction Engineering Management from Oregon State.

An excerpt from today’s Gazette Time’s Article: “Wally and Beth marked their platinum wedding anniversary with a luncheon Tuesday at Stoneybrook Lodge and will celebrate again with friends, family and members of their church on Saturday at the First Congregational United Church of Christ…. And the key to a good marriage? “There is no key,” Beth said. “You have to work it out. Usually, you have more good times than bad.”

Carl and Greg Frame new Pumphouse

As Seen in the Thursday November 15th Green Belt Land Trust Newsletter:

Carl and Greg volunteered to build a new well pump house for Greenbelt land trust.


Building a Pump House for Greenbelt Land Trust

On a cold Saturday morning two great volunteers from Christianson Construction headed out to Lupine Meadows to construct a much-needed pump house for Greenbelt … how cool is that?!

At this time of the year we often pause to give thanks to those who enrich our lives and communities…THANK YOU Greenbelt Volunteers!


We have just received word that our most recent new home construction project will be featured in Oregon Home Magazine. The architect for this project, Don Livingstone of Livingstone Studios Architecture & Planning, LLC wrote to the homeowners John and Bea to inform them that:

Oregon Home Magazine wants to feature their house in the magazine and will be sending a writer down to check it out sometime after the first week of May.

I will add a blog posting and link to the article once it is published.

We are very proud of the fine craftsmanship, design, and quality materials that went into John and Bea’s home. Please give us a call if you would like to know more about this project, or if you would like us to build your dream home.
