"Lisa is a genius! With creativity and precision, she maximized every nook and cranny of our tiny 1906 cottage and brought it into the 21st century, while maintaining its original charm and character. Our "new" home is so much more functional now, and a delight to live and work in. Lisa took the lead on our projects (kitchen, bathroom, basement), but Adam is equally savvy. Both are fantastic listeners, brainstormers, collaborators, total professionals and all-around lovely human beings. We highly recommend Christie Architecture, and look forward to working with them again in the future!"

"The project was essentially a remodel of a circa 1950's beach cabin with a small addition. We chose Baker and Son on the recommendation of our neighbor who had used them to build a detached garage. Our plans were relatively simple at first: build the addition, expand the kitchen, build a new bathroom and create a new entry. As work was underway, it became clear through the advice of Baker and Son that our kitchen was too big and out of scale for the cabin. We ended up eliminating some walls and opening up the cabin in such a way that created one large room but still a separate kitchen, dining and living. It was a huge improvement to the original design. In addition to the interior work, Baker and Son completely overhauled the exterior which included new windows and siding. New structural headers were required because they didn't exist. Also, since the cabin is post and pier construction, they leveled and strengthen the existing structure. Work included new skirting as well. Their attention to detail was very impressive. They are masters at creative problem solving, patient, responsive and positive. They have a very strong sense of design. We were never pressured into quick decisions. The contract arrangement for our project was essentially time and material because formulating a bid on an old cabin remodel would involve too many unknowns. We agreed to a fair hourly rate and all material and subcontracted work we paid directly with no additional overhead or fee. This saved us money. Since we lived out of town, Baker and Son were so well connected with various vendors and subcontractors, it simplified making arrangements. Now that our project is complete, we are so excited about the end result! We would highly recommend using Baker and Son Construction for any project."

"Ray was very professional and punctual. Even though my project seemed small to start with, it had a few difficulties to work with. He coordinated well with the Structural Engineer to get things right and absorbed a lot of work to get the drawings done on time. He is very prompt on returning phone calls or e-mail messages and answered all my questions. He was pretty detailed in his drawings as well."

FAQs for basement remodeling projects in Walla Walla, WA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
