"We recently had our kitchen remodeled and expanded by removing a wall to create an open floor plan. The contractor did an outstanding job. Throughout the renovation, they kept the site immaculately clean, which was much appreciated as we were living in the house at the time. They were always respectful of our space and provided knowledgeable recommendations for suppliers and installers. The entire process was handled professionally, and we are thrilled with the results. Highly recommend!"

At Matriarch Construction, we take pride in our work. I promise to take extra care as if it were my own home. Let me show you why all my customers refer me to their friends and neighbors. We get the job done right the very first time, to eliminate any problems. We look forward to discussing your next project. We are women owned!!!

"Costs increased about 10% over estimate, work was well done and the final product was professional and well-built. Communication could have been better, the builder promised weekly meetings but that didn't happen. All in all, we were happy at the end of it all, and all questions were answered and all finishes to our satisfaction, which if you've ever worked with a contractor before, you know isn't a given. 5/5 would work with them again, the fireplace mantel and threshhold was particularly well done."

iCornerstone offers design through construction services and promotes Consumer Controlled Construction as a solution to over-pricing, under performance, unrealistic allowances, and quality issues. We provide designs, labor and material specifications, accurate project costs, camera monitoring, invoice review, project accounting, and construction support that allow the homeowner to act as the general contractor easily and with a minimal time commitment. The first three carry an hourly rate of $100, while the fourth is 15% of the cost of the work as you have defined it. After a free Initial Consultation, we provide a proposal for the cost of our services. Our platform networks regulators, engineers, subcontractors, service providers, and suppliers involved in your project so that everyone knows what everyone else knows, which is the hallmark of transparency and accountability. Everyone is on the same page. Their E-folios resolve the dilemma of "If only I had known, I would have asked." Everyone benefits, and nothing like the platform exists in the industry. Clients must provide us the names of subcontractors we do not know as a means of proving to themselves we do not steer business or have a conflict of interest. This strategy helps our network grow and ensures fairness. Our free, online, Consumer E-Folio / Project Organizer / Property Profile / Research Tool will help you, even if you do not involve us in your project, comes with no strings attached, and respects your privacy. Simply register at icornerstoneinc.com and have fun using it. We claim three remarkable achievements: no client has ever gone over budget; no subcontractor has ever been overpaid or unpaid without cause; and all clients receive the highest quality at the lowest price.

"Great work, fast and responsive"

FAQs for addition to existing structure building service projects in Princeton, MA

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.
