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.

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.

Nik and Angie wanted to do some major remodeling to their home that was built in 2002. The major additions were a new master suite and bath, additional garage bay, and a new craft and bonus room. They also wanted to update all of the bathrooms in the home, replace the existing heating/cooling systems, replace carpeting in five areas including the new craft and bonus room, install new organizing rods and drawers in the master closet, add a special coating to the floor of the garage, expand the driveway, add a gas line to the patio for the grilling, replace all of the windows in the home, and add eight skylights.


The new Master Retreat and closet have Oak hardwood flooring throughout. New Milgard Montecito windows let a lovely amount of light in, complimented by three Velux skylights. In the Master Retreat bathroom, Wichita art glass has been added to the picture window to add some unique detailing. The Master Retreat bathroom has heated Travertine tile floors. The cabinets are Huntwood Rustic Alder cabinets in an Arroyo style with under-mounted Kohler sinks and Marble countertops. The countertops and flooring are complimented by Mosaic Cabernet glass accent tiles. The flooring in the shower is a sliced olive stone.

In the other bathrooms, the same marble, cabinets and flooring were installed. Toto ADA toilets were added to all the bathrooms and all doorways were widened to make the home adaptable if the homeowners wish to Age-In-Place. A curbless shower was installed in the Master Retreat bathroom to reduce the tripping hazard. A vanity area was created for Angela so she can sit and relax in her Master Retreat and to have an area with special task lighting.

Multiple niches were created in all of the showers to add needed shelving storage in the showers. Seats were added to the Master Retreat shower and the Hall bathroom. A Velux skylight was installed into the Hall bathroom to provide extra lighting as there are no windows in this bathroom. A Symphony Aquatic Air tub was installed into the Master Retreat bathroom and a Fiber Fab soaking tub was installed into the Guest bathroom. All hardware is Oil Rubbed Bronze by Moen and Delta.


In the craft and bonus room, guest room, stairs, den, and office we installed Tuftex Venecia Fantasia 527 carpet. Velux skylights were installed into the bonus room and into the craft area with remote controlled electric blackout blinds. New Milgard Montecito windows let a nice amount of light in, complimented by four clerestory windows. All paint is Sherwin-Williams’ Duration Home for all walls and ceilings.


The entire remodeling project took 10 months to complete and included nine additional jobs requested during the remodel. Nik and Angie are thrilled with the completed project and look forward to living in the home for many years to come!

Bill and Tammy’s bonus room above their garage is in full swing. We have completed siding, drywall and bathroom tile. The next step is painting the interior trim with oil based paint for the highest quality finish and then installing the 8” hand scraped factory stained and finished hardwood floors. Since the floor planks are about three times as wide as a standard hardwood floor, we have to add special gluing and nails to attach the floor well. The dark, wide planks will give the space a rustic charm without looking too busy. Once the floors are in we can finish the trim work, install the countertops, doors and wrap the project up. Their addition is spectacular, you can see the progress we’ve made in the past two months.

Mark and Betty meet with us in September to plan out a new workshop space at their home in Albany. We hired local designer Jack Scovile to design a lean-to style garage behind their home with plenty of room for Mark’s workshop projects. Since they live on a hillside we were originally going to excavate about 6’ to 10’ deep into the hillside to make the workshop at the same level as the existing garage. However, we found that the excavation and concrete costs were too expensive. After consulting with Mark and Betty, we re-designed the project to include significantly less excavation and shorter retaining walls and reduced the project cost 20%.

Excavation started in January after we received permits from Albany. Due to the narrow space between their property and the neighbor’s we decided to use a mini-excavator and a tractor to transport the dirt out to dump trucks in the city street. With excavation complete we set foundations and retaining walls. Mark decided to add some concrete steps and a concrete patio. We quickly created a written change order and were able to get them started at the same time to maximize our efficiencies and keep his costs low. Framing for the garage addition will begin in about one week. Our schedule predicts a completion date around March 15th. I will post more updates to follow.

We work very hard to build projects that accomplish your goals within your budget! Please give us a call for a free estimate for your project (and advice on how to keep the costs within your budget).

Our clients Bill and Tammy approached us to construct a bonus room above the garage for their exercise equipment with an additional bedroom and bathroom for guests. Our designer drew up plans and in order to achieve their goals we are adding 10’ on the back of the existing garage and mudroom (a 10′ by 33′ addition). You can see the picture in the drawing which will serve as the enlarged footprint for the new bonus room. The current garage will be left as is and the addition that we are adding will provide room for both the stairs to the upstairs and additional storage for the garage.

This project has a few unique challenges including installing a 2 hour fire rated wall so that their home can be considered two separate structures for the Philomath fire marshal (so we don’t need to install a residential sprinkler system). We are also keeping their existing home operational including their furnace and electrical panel which are directly underneath the new construction.

We will post more photos as we make progress. Trusses have arrived today.

We did a great job making their new garage match the existing house, in fact one of Mike and Terri’s neighbors asked “what did the contractor do at your home?” because he didn’t realize the carport was replaced by a new garage.

Mike and Terri gave us a call in February about enclosing their carport with two new walls, doors and a new garage door. They hired Bruce Osen to create a hand drawn design to capture their ideas and the spirit of their home. I told Mike we could start as soon as he desired. Once we agreed on the price of the project and had the permits in hand we began by temporarily supporting the carport and roof by installing temporary posts and beams. Then we removed the old columns, sawcut the slab and dug out the old concrete. Next we poured new reinforced concrete footings and stem walls. Our crew framed up the new walls with 2×6 lumber, OSB sheeting for shear strength, 5/8” exterior AC grade plywood sheeting and battens to match the look of the house’s siding. One of the hallmarks of our projects is that we focus on making the addition seamlessly match the existing house.

We installed two ThermaTru fiberglass doors with Sclage F51 Plymouth knobs and Schlage deadbolts. We installed a Therma Tech insulated Traditional Raised Panel Steel Sectional garage door with a Genie Chain Drive garage door opener. On the north side of the garage we installed three PlyGem horizontal sliding windows to let in fresh air and light. Inside the garage we installed drywall and paint. The city required a new layer of 5/8” fire rated drywall on the walls between the house and the garage. Mike and Terri are also going to replace the doors into the house with new fire rated doors. Mike and Terri are very happy with our work.

Please give us a call if you are tired of your carport and are ready to convert it to a garage! 541-754-6326

I just took some great “after” pictures of Paul and Doris’ Master Suite Addition, living room remodel and laundry room remodel. This project began last year in their desire to stay in their two-story home, but have an accessible master bedroom and bathroom on the first floor, which would allow them to age-in-place. Two years ago, we remodeled their kitchen, nook and built a new deck with the intent of adding the master suite in the future. We hired local designer Susan Harthun to design 450 square feet just behind laundry room (and integrating the home’s exterior appearance and landscaping). The new bedroom addition is spacious with a vaulted ceiling, built in wardrobe cabinets, an Andersen door to the new deck, unique lights from Radiance by Design, red oak hardwood floors, extra insulation, large windows and lots of evening sunlight. The bathroom has a large soaking tub, marmoleum floors, an accessible custom tile shower with no curb, and a Silestone makeup counter. We reconfigured the laundry room to be more efficient. In the living room we removed the aged “faux” beams, replaced damaged drywall, installed new hardwood floors, new paint and new trim to match the rest of their home.

Rose and Greg wanted to make their 2nd floor master bedroom Aging in Place accessible, but the stairs couldn’t be overcome without an elevator. Instead they hired Susan Harthun Designs to create a master bedroom that looks like it was always a part of the original house. The plan included 600 square foot adjoining the garage and the family room. Susan designed the addition’s roof ridge line to line up with the existing roofline.  A high roofline allowed us to vault ceilings.  We modified the design to include an additional entry to the master suite from the garage with contingencies for future accessible ramp.

The addition included a new Aging in Place accessible master bathroom with an accessible no-curb walk in tile shower, a jetted tub, grab bars, a large skylight and two large windows to give the room plenty of outdoor light.

In the bedroom we installed a new Andersen patio door that opens onto the deck. The project included radiant floor heating under the bedroom hardwood and bathroom tile with digital temperature control. To create a cozy bedroom atmosphere, we installed a small natural gas stove.  For cooling, we installed a high efficiency mini split air conditioning unit. To keep the heat in, we air sealed the addition and installed insulation in the walls, floors and attic.

We custom built a cherry window seat to match the detailing of the Amish furniture.  Over the window seat we installed a bay window with two side casement windows. To match the bathroom, we installed Ceasarestone window sills for continuity. The walk-in closet includes custom shelving to access the entertainment center wires.

Their living room was a nice but uninviting area, so in order to make the room more comfortable, we upgraded to new insulated windows in the dining and living room area.  We added a new gas fireplace with a custom fir mantle, tile surround and recessed lighting. Another window was added to the room to increase daylight.

Framing at Paul and Doris’ house is progressing at a fast pace. We are adding a master bedroom and a master bathroom on the main level of their home and finishing it to their custom specifications. In a previous blog post, I uploaded some renderings that we used to help finalize the design. I’m looking forward to see how the renderings compare to the final pictures.

On Saturday, our framer finished setting the trusses and sheathing the roof. You can see in the photos how the ceiling in the master bedroom is vaulted to maximize sunlight into the room. This week our roofer will install new shingles and the plumbing and mechanical work will be “topped out”. This means that they will extend the plumbing into the walls and ceilings so that we will be ready to install drywall. Next week, the electricians will finish their rough-in work as scheduled. The electrical wiring will be run through the walls and ceilings for the outlets, switches and lights. Following that we will be installing insulation and drywall will follow.

The vaulted ceiling in the master bedroom is really spectacular, I don’t think the pictures below do it justice. We worked with the truss company to build trusses with additional vaulting height (above what was originally planned and shown in the renderings).

Please call if you are interested in more details, or have a project you would like to discuss.
