At Allshire Building LLC, we pride our company on reliability, communication, integrity and quality work. We are experts in our trade and will do our best to keep you as educated as we can on your particular project. We look forward to earning your business!

"I recommend Allshire highly and without reservation. Russ, John, and all their crews were professional and we felt comfortable throughout the process. Our bathroom was fully gutted and rebuilt (with same footprint) - the end result was fantastic and I believe the value was very high. Just to make others aware - we had a fair amount of back and forth with the inspectors from our township and had several hardware items delivered to our house that were broken so they had to be re-ordered - so job took longer than we (and Allshire) expected. That said, the company has many positive attributes: 1) communication is solid 2) attitude is positive and professional 3) final workmanship very high 4) pricing very reasonable 5) overall demeanor is friendly and flexible which is what we wanted. We will call them again when we get ready to remodel our kitchen. Allshire is a good company because it is made of good people."

FAQs for addition to existing structure building service projects in Plymouth, MI

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.
