"In Spring 2024, Bob responded to our request to add a roughly 240 square foot addition to the back of our house. From the first phone call to the final walk through, Bob was a trusted presence and thorough communicator. He listed to our requests, answered our questions, offered suggestions and explained challenges in a consistent, clear and timely manner (which was extremely appreciated for first-timers going through this process). It's been roughly 8 months since completion and having a new office and family room has made a HUGE difference in my family's quality of life. His costs were fair and, given that we made some slight tweaks to our original plans, we stayed roughly within budget in terms of time and money. I highly recommend Bob and his excellent team of subcontractors as well."

"I had the pleasure of working with Mike, a general contractor for my multi-unit investment property on the northwest side of Chicago. Mike demonstrated a strong vision for how to add value to the property, offering creative solutions (adding livable square footage to the attic unit for a duplex up) that made a significant impact. His attention to detail and ability to identify areas for improvement helped enhance the property's after rehab value, all while staying within budget. What stood out most was his excellent communication throughout the entire process—he was always available to address questions or concerns and kept me updated on progress (daily updates). His professionalism and efficiency were unmatched, making the project run smoothly from start to finish. I highly recommend him to anyone looking for a reliable, skilled, and thoughtful contractor."

"We had a linen closet built in our master bedroom & a long section of concrete from an old patio cut away to give us a little more driveway space & we would recommend this company without hesitation! John came out to give us an estimate within a day of the request & was very courteous & positive about our request. Love that he said, "no problem" when he heard what we wanted done. & we couldn't be happier with Peter's work! He did a great job & was always on time & very professional & courteous. We trusted them in our home & will definitely hire this company again!"

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