"Builder Land did an amazing job with my project! I can't recommend them enough-very pleased with their work and the experience working with them! I have a small business that I wanted to add a shower and have the existing bathroom remodeled. From the beginning Edward took the time to hear all the details of the project and understand them, he also was very helpful with offering ideas when I was unsure of some of the design details. He has a good eye for excellence and didn't miss a detail. Edward and his crew were very professional, personable, respectful and cleanly. Within 48 hours of committing to the project he started the demo and it didn't stop until it was fully done in the projected time. 10/10 recommend going with Builder Land!"

Excel General Contractor is a full service home remodeling and construction contractor. We offer a high level of customer service while maintaining fair pricing. Our team is small enough that you get individualized attention but big enough to get your project done effectively and efficiently. We do all projects from small repairs and renovations up to designing and building you a complete new custom home.

"Nate allowed me to order my bathtub myself, which was nice. Lowe's failing to deliver when promised, was not. This delayed the start, and although it did take longer than I expected, everything came out great. They did not charge me extra after the water damage was exposed, which was a relief. One of the other estimates I got from a general contractor was for 3x as much, AND they planned to add on after the wall was opened. The bathroom specialists wanted 150% of what we paid, and I think we ended up with better results."

"I had Okay Construction renovate my entire house, including the kitchen. They also changed the electrical panel, all floors, windows, and doors; built new stairs; and installed several skylights. They can do pretty much anything you ask. Bo is very easy to communicate and work with. We needed to move in from another state, and he made sure my second floor was ready when we needed to move by having many staff members work long hours and on weekends. They turned my old house into a beautiful, bright home. Bo can recommend where to look for renovation materials and where to get contractor pricing. We applied for permits for all major projects, and Bo took care of them for us. They also have a warranty, so if anything goes wrong, he'd be happy to come back and fix it. Bo keeps his promises and is very patient. One of our ovens wasn't working right out of the box, and he took it out and re-installed it (and the replacement) many times. He also has many good ideas for small touch-up project"

FAQs for addition to existing structure building service projects in Redmond, 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.
