G. Christianson Construction is proud to have won two Earth Advantage Builder of the Year awards, which recognize achievements in sustainable & energy efficient construction practices: Lowest EPS® Score & Zero Energy!

As an Earth Advantage builder, G. Christianson Construction entered the first PHIUS certified passive house in Corvallis, Oregon. We completed this passive house in 2016, incorporating a variety of systems & materials to create superior energy efficiency and indoor air quality, as well as being environmentally responsible.

This custom home was built to use 70% less energy than a code built home per the world’s most rigorous Passive House standard. It achieves this by very limited infiltration, thermal bridge free construction techniques, super insulation, and heat recovery ventilation. Its 12” thick walls boast an R-value of 51.8, obtained with 2” of cork insulation over BIBS wall insulation. The 32” thick roof has an R-value of 102.4, while the 17” thick floor has an R-value of 63.9. High efficiency doors and triple paned windows, contribute to its energy efficiency. It also has 8.25 kW solar panels, Energy Star appliances, and natural daylighting to keep its energy bills low. A typical Oregon home of a similar size built to code would have a carbon footprint between 19.1 to 20.6 tons of carbon dioxide per yr.; this home has a carbon footprint of 4.0 tons per year before the solar array, which brings it down to 0 tons of carbon monoxide. The home was computer modeled to make sure it met PHIUS energy requirements. By adding solar panels on the garage this home is Net-Zero energy usage.

Indoor air quality has a huge role in overall health. Where possible, this home has eco-friendly building materials that off-gas fewer harmful chemicals. Its ventilation system not only prevents heat loss, but also reduces airborne contaminates, reducing the chances of health risks like allergies, asthma, and more serious health detriments.

During the construction of this home the landscape was taken into consideration as well. Practices to promote healthy landscapes were implemented. Erosion was minimized by use of straw and minimizing vegetation clearing and deforestation. The landscaping uses many native species and avoids the use of invasive species.

This home’s materials were chosen with the environment in mind. Where possible, locally sourced materials were chosen. All the materials chosen are durable and high quality, to last a lifetime, if not generations.

Water conservation was also addressed in this house. It has metal roofs and gutters plumbed for rain water catchment, Nebia low flow shower heads, and a weather dependent irrigation controller to reduce household water consumption without sacrificing comfort.

In addition to its environmental efficiency, this gorgeous home boasts grey quartz countertops atop white and blue painted shaker cabinetry, dark stainless steel appliances, and a subway tile backsplash in the kitchen. Elegant white walls bathed in natural sunlight accentuate the hickory flooring throughout, with a wood inlay feature to add a nautical flair to the transition from the kitchen to the family room. The sleek bathroom has a seamless tile shower with mosaic accents and modern vanity with clean lines. The reading nook under the stairs in the family room is a cozy spot to curl up with a book. Expansive views greet you through every tilt & swing triple paned window.

Designed with “Not So Big House” principals to be effortlessly comfortable using minimal energy, with exquisite finishes and details, this home is a beautiful and cozy retreat from the bustle of everyday life.

1915 Bungalow Receives an Historic Bathroom Addition

The owners of this property visited G. Christianson Construction last summer after purchasing this 1915 Bungalow in Corvallis (near the Public Library). The problem: The house only had one bathroom. The solution: Add a 5′ by 14′ addition off the Master Bathroom.

Superintendent Steve Schoonover, who has been part of the G. Christianson team for 23 years, was just the person for the job. Steve passionately restores historic homes, and had worked on this house about eight years ago when G. Christianson restored the kitchen and front deck to it’s former glory. The previous owner kept a detailed book of restorations, which she passed to the new owners, which brought them to us.

Designer Sue Rutherford created a dream, our craftsmen went to work building the addition to match the home exactly. Then we hired one of the best tile masons in town to install the shower, wainscotting and floor tile. The tile work stayed true to the flair of the existing bathroom, with white subway tile, black pinstripes with diamond accents, and white grout.

The result: A 70 square foot spectacular Master Bathroom addition with 1915 glamour and modern amenities. The bathroom boasts a Moen Wynford shower head, American Standard faucet, Toto Carusoe toilet, custom white painted cabinetry, a custom built medicine cabinet, Corian countertops, Simpson Fir F55 door, Emtek Quincy plate with a Providence door knob, Velux skylight, and a Marvin Ultimate double hung window in Wineberry color.

The homeowners love their new bathroom, it is everything they wanted and more!

The praise we received from all of the neighbors is that this addition fits seamlessly with the home’s original look, this is exactly what we intended.

Progress Continues at the Passive House on Hawkeye Ave.

We have some great news: The G. Christianson Passive House is now PHIUS+ 2015 Pre-Certified, and PHIUS+ Source Zero Pre-Certified! This means that the solar panels on the garage provide all of the power for the house and proves that the house will use the amount of energy that the design predicted.

Passive House building is an exceptional way of reducing energy use of a home by 70% or more. Passive House building is supremely comfortable, has a healthy indoor environment, has a resilient and durable structure, and has an extremely low utility cost with a reduced carbon footprint. This is the best path to a NET ZERO or Positive Energy house. We will accomplish this by using the following techniques:

1. Install super insulation

2. Create air tightness with a fresh air ventilation system

3. Eliminate thermal bridges

4. Install exgtremely high performance windows and doors

5. Optimize Solar heat gain design through 3D building modeling

Project Update

Framing is complete at the G. Christianson Passive House, and work has begun on interior details. Our team took a trip to the house to perform a blower door test before drywall work closes up access to the stud bays of the walls. A blower door test detects the amount of air pressure that leaks through any cracks or gaps. A standard new house leaks between 3-5 air changes per hour under pressure. A Passive House requires that the home be no more than 0.6 air changes per hour. The G. Christianson Passive House tested at 0.29 air changes per hour – less than half of what our goal was! We’re moving forward with a strong number under our tool belts.

There are a lot of aspects of this house that are unconventional – and we expect to see these building techniques become the new normal. The foundation was upgraded to meet Fire Station Seismic Code levels. We framed 8″ thick walls, which allows for R-29 blown-in fiberglass insulation. In comparison, standard building code requires R21. We are also installing a 2″ layer of sustainable-harvested cork to the exterior of the home, which will go underneath the siding. The added exterior insulation provides a layer of breathe-ability and an additional value of R8 insulation.

The next phase of building is to install roofing, which is a copper-colored standing-seam metal roof – and one of Carl’s favorite design aspects of the home. The siding is Hardie panel siding with Boral trim. Simultaneously, we are working inside installing the drywall and getting ready for finishes like flooring, tile, and custom cabinetry.

Shows on HGTV highlight beautiful additions and remodels, like the one pictured below that we’re working on in the Corvallis Historic District. But seeing so many before-and-after photos makes it easy to forget that construction, like art, is a process.

This 96 sq. ft. addition adds a Master Bathroom to the currently one bathroom 1915 Craftsman house. Our team put a lot of effort into matching the exterior of the addition to the original home. The photos, while not the the last step of construction, highlight the continuity of the addition with the historical markers of the original exterior, like the custom trim work and soffits.

“The outside of the addition looks as if it’s been there all along,” the owner says, which is exactly what the team at G. Christianson strives to accomplish with any addition, be it a historic home or a contemporary building.

The interior of the addition houses a vanity, a recessed medicine cabinet, and a whole lot of custom tile work. The owners chose to keep with the historic ambiance of the interior of the house and selected white subway tile with black pinstripes, which matches the existing bathroom. The vanity lighting and chrome hardware add a touch of modernity.

Sandi and Roger met with us in 2014 to re-build their deck and plan ahead to install a covered porch. After listening to their ideas, we created some drawings in Google Sketchup of what the covered porch might look like. They asked us to build around their lilac bushes, so we designed a covered porch with “clipped corners.”

This created a challenge because it is nearly impossible to frame an exposed beam, vaulted ceiling with clipped corners with wood rafters. We brought in our structural engineer and worked with him to engineer a “flitch” beam, which consists of a 3/16” steel plate sandwiched between 2×8 roughsawn rafters.

31-IMG_8605

After two weeks of framing, the rafters were done and the Tongue and Groove ceiling boards were sealed and installed. Our next step was to re-roof the back portion of their home, then paint, install screens and the skylights.

Sandi and Roger are thrilled with the finished porch and workmanship. Please give us a call if you would like to create a spectacular outdoor living space 541-754-6326.

Our client met with us this spring with the concept of opening up her dated 1950’s bathroom, getting rid of the pink tub and pink sink and making an “Artic” oasis. She wanted to maintain a white with “Artic” green/blue theme. We created some design options using 3D software and presented the options to our client. After some simple revisions to the design and products were chosen within her budget to match her goals we started the remodel.Our exceptionally detailed contract allowed her to understand the scope of the project and be sure that we had covered everything. We also offered electrical safety and insulation improvements. Construction began in June 2015 and was completed in early August (we had some delays with the imported tile).

One of the features of this bathroom is the floating vanity and floating LED backlit mirror. The mirror has color changing LED lights. You can use a small remote control to change the color and brightness to match your mood. This lighting really draws your eye towards the glass tile and provides subtle ambient lighting for nighttime.

She is thrilled with our work and her friends are too. Please give us a call if you’d like to build an spa-like oasis in your home.

Some of the details:

  • Cabinets: Floating “European” frameless with conversion varnish over white paint on maple plywood
  • Countertop and Sinks: Corian Cameo White with a thickened front edge
  • Shower tile: AKDO Thassos Honed Marble 3×6
  • Glass tile accents: AKDO Stagger Fusion Mosaic (Icelandic Blue, Thassos P, Seashell)
  • Tile floor and Base: Emser Pietre del Nord “Vermont” matt 12×24
  • Paint color: Sherwin Williams’ Glimmer – SW 6476
  • Exhaust fan: Broan QTXE110S

Mike & Tricia asked us to build them a different kind of deck in their back yard. When they came to us, they had already hired Bruce Olsen, a local architect to design their deck. Bruce’s beautiful, hand drawn deck plans featured Asian influences including a copper covered lantern. We provided a contract to build the deck using Trex Earthwood Evolutions composite decking. The handrail, trellis and detailing is cedar.

_MG_4130

All of the framework of the deck is pressure treated lumber. As pressure treated lumber is not immune to water damage, we take extra precautions above and beyond standard building techniques. We spray cut ends of lumber with additional rot preservative. We also form concrete around buried posts to cause water to flow away from the posts.

The decking is attached with Tiger Claw hidden fasteners. The cedar is attached with Fastenmaster Split Resistant screws. We take extra care when installing our handrail posts to be absolutely certain they will remain rock steady for the life of the deck. We use galvanized through bolts and Simpson DTT2Z hardware to ensure that you won’t have that “wobbly” feeling in our posts five years after we leave.

_MG_4131

We noticed during construction that some details of the deck design might not work for our customers. The bench was designed to be very low, common in an Eastern deck, but not very popular in the West. We also felt that some sections of the handrail could be changed to better suit the landscaping in the back yard. We generated three dimensional drawings of some sections of the deck and talked with Mike and Tricia about our concerns. Working with Bruce and the owners, we came to a solution that worked for everyone involved.

_MG_4132

We built the framework for the copper lantern and took it off site to a fabricator who installed standing seam copper. The lantern has frosted glass walls with clips to allow easy removal for cleaning. Inside is a simple LED bulb. We were able to build it so the wire is completely hidden from view and goes to a switch just inside the back door. The lantern looks lovely at night. We also custom built housings for two mail-order planters Mike and Tricia picked out.

_MG_4135

A lot of elements came together to make this deck. Bruce’s vision is extraordinary. G. Christianson Construction’s building know-how, and foresight caught many potential issues before they became problems. Our lead carpenter and our office staff came up with many innovative solutions to the special set of challenges in building this one of a kind deck. Call us today to make your dream a reality!

Gerry and Carroll invited us to their home in July 2014 to look at replacing their dated tile countertops and updating their backsplash. While updating their countertops, they chose to upgrade their sink to a Blanco Diamond 1 ¾ Metallic undermount sink and we re-installed their existing faucet. They picked out Coastal Green granite and we repainted the kitchen walls to match.

 

01-IMG_8137

For the backsplash, the owners chose glass tile. Glazzio Glacier 4×12 glass GL88 glass tile and Crystile 4×12 glass tiles provide depth and interest to the backsplash. The pops of color in the backsplash incorporate beautifully with the colors of the cabinets, counter tops, appliances, and paint. To further highlight the gorgeous backsplash and to provide additional task lighting, we installed new LED strip lights throughout the kitchen.

02-IMG_8139

In the design phase, we located the original cabinet makers and arranged for them to come in and touch-up the cabinets. Now the cabinets look as good as the day they were originally installed. We installed new window sills and trim and re-lacquered them to match the existing woodwork. We replaced the dated appliances once we finished installing the new countertops.

Carroll and Gerry are very happy with their updated kitchen. They were grateful to our crew especially during tile countertop demolition for their care and attention in not damaging the existing cabinets. They were also very impressed that we were able to get the demolition, countertops, plumbing, appliances and backsplashes completed in one week so they could start cooking again.

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.
