"The job was to demo, temporarily support and then reconstruct a two story wooden structure supporting a roof overhang on a split stair structure for an apartment complex. It was a tricky project. Not only did they complete the work on time and budget, they came up with 3 great ideas to solve some typical retro fit issues that come up with jobs like this. They also did a good job cleaning up after the job was complete. They really know exterior framing."

FAQs for addition to existing structure building service projects in Big Rock, IL

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.
