"Had them rip out the fireplace that was installed poorly in 1990. A bit costly, but I doubt a single handyman could have done it in a timely fashion. Done in 3 days start to finish. I was expecting some water damage, but it was much worse. Getting a exact price for the work out of them beforehand was impossible. Ultimately it cost $2500 extra do to having to replace more sections of the roof and support beans. They didn't pull a fast one, the wood crumbled when touched. Labor isn't cheap. Would hire them again because the work is solid. "

"I wanted a sturdy shed built on my poured concrete slab. I knew how large I wanted it, but after that, I needed help. Nate worked with me to design, build and finish my 12x16 shed from start to finish. The process was efficient, and the shed is beautiful. Honestly, what I call a shed, would probably classify as a garage, had we installed a garage door, but that was not what I needed at the time. While working with Nate, I quickly recognized he could be trusted to find a solution to any problem. Next he helped me plan and built a matching railing for my home’s staircase, after I had previously removed an old rotting one. Again, this process was quick easy and friendly. Sadly I moved away from the area, but if I ever return, I will always reach out to Nate first for my building and remodeling needs."

Koi Construction, LLC, originally established as HK Design & Remodeling and M&I Property Services, has always started from modest beginnings. Our core belief is that true success comes from engaging passionately in our work, rather than being driven by financial motives. We are committed to excelling in our projects, making a distinct mark through exceptional performance. Our unwavering focus remains on outstanding client service and superior craftsmanship. Despite our growth, we steadfastly adhere to our fundamental mission: "To achieve ongoing success by ensuring client satisfaction, delivering high-quality services, and upholding genuine integrity, all of which culminate in the finest craftsmanship."

"The whole experience was excellent. Chris when to give us a bid. He was very knowledgeable. He told use about the triangle of stove, fridge and sink and flow. He suggested a long narrow window to replace the tile backsplash on an outside wall. It was a great idea. When sit at the new bar between the kitchen and the living room we look out into our backyard. Itâ s beautiful. The guys that did the work are extremely work oriented. They are constantly working. They were thorough, knowledgeable and open to our suggestions and requests. We wanted an additional can light no problem. They were great. They cleaned up every day before they left. They would tell use when they were going to arrive and what they planned to accomplish that day. I have old siding on the outside of my house. They matched it perfectly when eliminated a window. The price of the cabinets was a lot more reasonable the other bids and theyâ re beautiful. What I mentally pictured in my mind on how it would look and the ease of preparing meals in the new kitchen were so wrong. Itâ s at least 10 times better. It still has the same physical dimensions but how itâ s played out. It seems so much bigger. I highly recommend them for any project you need done"

FAQs for addition to existing structure building service projects in Olympia, WA

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
