"I had a fantastic experience working with Tyson and the team at Westward Renovations from start to finish. I came to them with a tricky jack-and-jill bathroom setup that I wanted transformed into two separate en-suite bathrooms. The 3D design modeling they provided was incredibly helpful in visualizing the final layout and making decisions with confidence. The project involved a full down-to-the-studs remodel and required multiple permits from the city, but Tyson handled everything seamlessly. He navigated the inevitable challenges of a renovation with professionalism and ease. The end result? Two beautiful, high-end bathrooms that exceeded my expectations. They also did multiple small jobs around the house that I am very happy with. I highly recommend Tyson and Westward Renovations—and I wouldn’t hesitate to work with them again!"

"Only thing they did themselves was the patio ceiling & French drain for my project. Acted as hiring contractor for all the other work. Overall project was a success, but I didn't appreciate how the lead crewman/ owner spoke to his employee. Subcontractors that were hired were excellent."

For the last 33 years I’ve been doing just that . I guess you can say “ I’m living my dream “. I do my best to listen to my clients and help them with the vision they gave for their. Communication from start to finish.

"I would highly recommend them!"

"My wife managed to accidentally run the car into the garage, the main post next to the garage door. And I also had some dry rot, under my kitchen window. Jose came right away.

I felt like a truly valued customer. I would not hesitate to use them again."

FAQs for addition to existing structure building service projects in Beaverton, OR

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.
