"We used Anton and his team for remodeling our basement and garage after we had water damage. They put up replacement pieces of sheetrock which looked amazing. Absolutely no lines just perfectly level walls. Their workmanship was outstanding. The owner was on site a lot of the time and his team worked very neatly. The painting was simply outstanding. The room looks like brand new. Pricing was extremely fair especially for such quality, high end work. Anton and European Craftsman will be our only call the next time we need work done. Thank you Anton!"

"Dave Nessel and his stellar company, Unique Construction NY Inc. are the BEST. Allow me tell you why- On May 15th 2022 at 5:45 p.m., my house was hit by, what electrical engineers later estimated, was at least 80,000 volts of lightning. That huge, direct surge of energy destroyed all the systems and contents that made my house more than four walls and a roof. In addition to the bolt of lightning destroying all the systems in the house, it caused a violent, destructive fire. Thankfully I was home at the time of the incident, or the house would have quickly burned down all the way down and my pets would have suffered a terrible fate. Still, after all was said and done what had been my home for seventeen years was reduced to nothing more than an outer shell. I was immediately forced into the position to find, hire, and organize tradesmen from all specialties, negotiate the endless complexities of homeowners insurance, all while trying to find a place to live and continuing my self-employed full-time work schedule. It quickly became clear I needed the services of a general contractor. I interviewed a couple, but as soon as I met Dave I knew he was the man for the job. Dave was always on time or early. He went through the house with a fine tooth comb for hours, noticing things and problems from the destruction I hadn't noticed. His expertise of every level of construction and understanding of all aspects of housing systems (electrical, plumbing, etc) was unmatched by anyone else I had interviewed. Additionally he had an understanding of the homeowner insurance protocols and was able to interject as a supporting role (only when needed, Dave never undermined me -I'm a single female homeowner-) with professional, easy to read, paperwork, accurately demonstrating all costs. I'm confident his detailed documentation made the long slog of negotiations with my insurance representatives a little easier. Under his expert guidance, his company gutted and rebuilt my old house to beautifully modern standards while maintaining its historical charm. The rebuild came in precisely on budget and two weeks early. Dave's company Unique Construction handled my complex situation with upstanding processional skill, old fashioned kindness, and outstanding forthrightness. Dave and his crew treated me with respect, rebuilt my home, and provided a little hand holding & TLC when it seemed I needed it and I'm eternally grateful. Anyone reading this should hire Unique Construction!"

FAQs for addition to existing structure building service projects in Croton-on-Hudson, NY

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.
