Arcanna Homes, Inc., is a family run home construction company that's been in business since 1989. From stick built to panelized structures, we use the fastest, highest quality home construction method available and can supply all necessary design, accounting, project management and professional labor. A new home or home addition built with Panelized Construction Technology can easily be customized, weather tight and secure in days and exceeds today's rigid construction financing terms! Panelized structures use cutting-edge automation and are built in factory-perfect conditions. Complete exterior and interior wall panels are pre-engineered and shipped to the building site for final assembly, offering substantial time and cost savings. WATCH THE VIDEO: https://youtu.be/7k81cF7p2rM

"I would recommend Arcanna Homes in a heartbeat. I had a kitchen renovation done (and I have a very small house) and we were treated like we were building a brand new home. Ralph answered all my calls (even when he was away) and even met with us over the weekend to help us pick out cabinets. His workers were all efficient and great (even through the hot July weather)."

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