Before Construction

Mike and Karen asked us to visit their home in June 2013 to replace their old, rotting back deck. They wanted to build an exceptional outdoor living space that extended their main floor into the expansive forest of Vineyard Mountain that surrounds their home. Our homeowners felt a tri-level deck would be best as it would incorporate the natural slope of the yard and give them the outdoor space they wanted. Additionally, a multi-level deck allowed our homeowners to have defined spaces, such as a dining area and a lounge area to sit by the fire, rather than just one large deck surface. Mike and Karen’s previous deck provided no access to the yard from the back of the house, so we made it a priority to give them access from multiple points on the deck.

We took dimensions of their home and built a 3D model on the computer to visualize the deck and made adjustments until we had exactly what Mike and Karen had envisioned for their deck. We also modeled various types of handrails that could accommodate undermounted lighting and then worked with J&J Electric to create the lighting plan. The homeowners also wanted the stairs to function as extra seating when they host parties, so we designed wide stair treads so their guests will have more places to sit. The next step was engineering and permits, and then construction. We started excavation in January, deck framing and decking in February, handrails were installed in March, and then the electricians installed the lights. We installed the natural gas fire table in early April.

Our homeowners choose Nexan’s NextDeck powder coated aluminum decking in Light Gray. Nexan says that “NextDeck is a revolutionary decking product that offers unsurpassed durability and longevity. Specifically designed to replace other high-maintenance decking products, NextDeck® delivers a truly maintenance-free choice. NextDeck® gives homeowners the freedom to enjoy their outdoor living space and activities, rather than spending countless hours and money on deck maintenance and repairs. Designed for the life of your deck, NextDeck® aluminum decking is fireproof, pest resistant and will not rust, rot, sag, splinter, warp or crack in freezing temperatures.”

Karen and Mike also chose a Stainless Steel Cable Railing system and Nexan’s Black powder coated posts to support the steel cables. The steel cable railing system allows anyone sitting on the deck to enjoy the various views of the yard without feeling like their sight lines are being obstructed. We installed LED strip lighting under all of the handrails along with step lighting on every other tread to provide safe access at night and ambient lighting. The fire table is an American Fyre Designs 48” diameter Contempo Round Firetable fueld by natural gas. We finished the deck with a Rustic Hardiplank skirt to match the home’s existing LP siding, the skirt also conceals the framing members. We also added a metal roof under the upper deck to provide a dry place to store outdoor furniture during the winter.

In the evenings, the warm glow of the lighting and the fire table make this a cozy and welcoming place to sit and enjoy the gorgeous, peaceful surroundings. Mike and Karen are exceptionally happy with the finished deck. They were thrilled with our work and dedication through the coldest and wettest part of the year to have this completed in time for summer in the Willamette Valley.

In 2013, Alpha Phi’s leadership met with us to remodel the Sorority basement. Their goal was to convert multiple storage rooms and a dark and dingy meeting room into a space that the ladies would enjoy using. Their priorities were to find a General Contractor who could provide great communication, timeliness, help with design, material selection, scheduling, and value. We were able to bring in our resources to meet the challenge and remodel the basement during summer break.    

 In 2013, we started the remodeling project; our 3rd at the Alpha Phi Sorority. The basement project consisted of two major pieces. First, we needed to create a large, warm, functional, and welcoming space. We created multiple spaces within this one large room for the ladies to study, watch television, socialize, or wait for their laundry to finish.

We demolished walls between the old chapter meeting room, hallway, maintenance closet, and the trunk storage room. We discovered the posts supporting the house had dryrot and needed to be replaced. That inspired us to add a steel beam to open the floor plan by removing one of the bad posts. We leveled the floor with gypcrete, replaced leaky pipes, insulated, added lighting, replaced a rotten piece of wall, reinforced the flooring system and installed new wiring.

 Once the old walls were removed and the dryrot was taken care of, we created an open area where the ladies could study or hold sorority meetings. A large table with room for 6 to sit comfortably was placed under a contemporary, but bright pendant light which provides ample task lighting for the table. Recessed lighting was added to provide more lighting on the white board and bulletin board that are located on the walls beside the table. Additionally, in the east side of the basement is a functional laminate storage unit with drawers and cupboards for the girls to store supplies. It also provides a flat large surface separate from the table to spread out paperwork or other study materials.

On the west side of the basement, another table was placed that will seat 4. This table can be moved around the room as needed by the ladies. Ambient recessed lighting and task lighting was placed around the west part of the basement that provides warm, but strong enough light for studying. A small reading nook was created in the west part of the basement to give the ladies a comfortable spot to read and provide more seating. This area is also a part of the lounge area and can be used when the ladies have movie night. In addition to the reading nook, a large microfiber sofa provides more seating in the basement. 


Reading nook and extra seating for the media area.

Shaw “No Limits” carpet tiles were chosen for the entire basement. These carpet tiles can easily be individually replaced if needed. New Mannington vinyl was installed into the laundry and bathroom. New MDF baseboard and casings were added after the new carpet tiles were installed. 

Second, we needed to replace the very old gas boiler and water heaters. We installed a new Lennox HRV3-150 Heat Recovery Ventilator to bring fresh air into the basement. We also installed a Lochinvar 95% high efficiency boiler with direct ventilation to heat the sorority house. We additionally installed a Bradford White 98% ultra high efficiency water heater and storage tanks to provide ample heat for all of the showers.

Room addition, apartment over garage

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.

Steve and Dominique called us last summer when they decided to move into an older home in Corvallis. The house had a dated kitchen in the center and with walls surrounding it, resulting in a restricted layout. With Rod Terry’s 3D design and Structural Engineering by Dan Herford, we supported the roof trusses with large LVL beams in the attic. Then we tore out the interior walls, the brick “pizza” oven, the dated kitchen, the old carpet, the brick fireplace, and the small windows.

The new floor layout is wide open, perfect for entertaining guests. The kitchen is now spectacular in the center of their home, the highlight is the wood countertop Steve built with bar seating. We installed beautiful Cherry Shaker cabinets, granite countertops, two new skylights, and a new Andersen patio door.  We also repainted their home and installed Red Oak hardwood floors throughout the home.

In the living room, we installed new Cascade Pro trapezoidal windows to complement the roofline. We removed dated wood paneling on the walls, installed seismic upgrades, and insulated their drafty walls. We removed the old wood stove and brick surround and installed a new gas stove. Steve and Dominique are very happy with our work.

Please give us a call if you would like to open up your cramped house layout 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.

Doris and Paul decided to upgrade their home to accommodate them as they age rather than sell their home and move. They were partially inspired by a friend’s difficulties with stairs.  We worked last summer with Doris and Paul to remodel and expand their kitchen and add a new deck. You can see photos of their new kitchen on our Kitchens page. That project was the first stage of a larger plan to update their home and add a spacious master suite.

We provided Doris and Paul with a Master Suite design build solution by working with closely with our clients and local designer Susan Harthun.  The key to this design is to move their master bedroom and bathroom to the main floor level and plan ahead for accessibility. Greg’s experience teamed with his Certified Aging in Place training helped with many of the crucial details. The new bedroom will have expansive windows, vaulted ceilings, custom cabinetry and a door to the deck. We designed the deck last year with the new addition in mind. In the new bathroom, we are going to install a full tile shower with no curb, a beautiful soaking tub and radiant floor heating. The cabinetry is going to be made by a local business Eager Beaver Cabinets out of Clear Vertical Grain (CVG) fir. In addition, we are going to be reconfiguring the laundry room to make it more useable.

The home’s heating system is somewhat unusual, because it doesn’t have a natural gas furnace. Instead, it has a high efficiency heat pump connected to a forced air ducting system. To save Paul and Doris the cost of replacing their heat pump with a larger unit and higher energy bills, we are going to build their new addition with added insulation and a strong focus on airsealing to reduce air leaks. We are also going to air seal and insulate the existing home. The heating system will be modified by adding a zone to allow separate control of the temperature in the master bedroom and bathroom.

We created some renderings earlier in the design process to help Paul and Doris visualize their project. Some of the details have changed since we made the renderings. The project is in the final design and bidding stage. We will have more pictures and updates as the project progresses.

Covered patio

Bring the outdoors and sunshine into your home. We recently completed a spectacularly beautiful sunroom for Richard and Cynthia. We worked previously with Cynthia on her business and because of our relationship, she felt comfortable asking us to build this Corvallis sunroom. The inspiration for this project came from the desire to have the ambiance of an outdoor hot tub, but without Corvallis’ cold wet weather.

The sunroom adds a warm, bright 325 square feet just outside their kitchen and living room. This is the perfect addition if you are suffering from Corvallis’ cloudy weather. To accomplish Richard and Cynthia’s dream, we turned to Westview Sunroom www.westviewproducts.com.

Westview Sunroom and Corvallis local Susan Harthun teamed up to create a design to accomplish the homeowner’s desires.

One of the charms of the sunroom is the stained and finished Douglas fir glulam beams. These beams support the glass roof.  In addition, the sunroom includes two operable skylights, a nine foot wide bifold door, a full glass roof system and full glass walls. We installed 3” of insulation over their old outdoor patio and then poured a new stamped concrete floor which is a great indoor/outdoor floor surface.

The sunroom project included a large hot tub which adds a lot of humidity to the air. To counteract this, we installed a Mitsubishi ductless mini split heating and cooling unit. The model we used is very energy efficient and works well as a dehumidifier. We also installed a big screen TV and entertainment center.

Corvallis Kitchen Remodel Before and After Photos

Pat and Bob asked us to completely remodel their dated kitchen to provide better functionality by increasing the brightness and updating the kitchen materials. In order to best use the space available in their kitchen we decided to use custom cabinetry from Eager Beaver cabinets (a local custom cabinet shop). We wrote the contract to give flexibility for Pat and Bob to change their cabinetry, countertops and tile work choices. If the costs were less, then they would get money back. The new kitchen includes Red Oak hardwood floors, Silestone countertops and Custom Tile backsplashes. As with many of our projects, we suggested adding a tile inset to protect the hardwood floors from wet shoes and scratches at the exterior doors. We designed the new cabinetry around their appliances saving Pat and Bob from purchasing new appliances.

A few things that you will notice:

  1. Remove the drywall ceiling soffits. These soffits were last popular about 20 years ago. Now we use the added space for larger cabinets.
  2. Remove the vinyl flooring, in this home we tested and found asbestos in the vinyl. A fully trained and licensed asbestos abatement crew made short work of the floor without spreading hazardous fibers into the rest of the home.
  3. The dated cabinets are gone, replaced with shaker style solid birch cabinets.
  4. The harvest yellow plastic laminate countertops are gone, replaced with solid surface Silestone to complement the cabinetry.
  5. A new stainless steel sink and faucet replace the old porcelain.
  6. The new microwave/hood now vents out through the roof, rather than just recycling the cooking fumes into the kitchen.

Partway through the design process, we realized that taller windows would help brighten the kitchen. We provided Pat and Bob with quotes to increase the window size and were able to accomplish this on schedule. Please call us at 541-754-6326 if you have a home project in mind, we’d love to come visit and help you accomplish your goals.
