"Tyler got the job done right, and went above and beyond. Deck flooring and railing replacement project. Quality of workmanship and materials was superior. Tyler listened to my ideas and proposed different solutions at different price points. He even painted the deck uprights, and went out of his way to replace a corner siding trim piece that was loose and in rough shape from a previous repair done by someone else. I would definitely hire Tyler again."

With over 25yrs of combined professional remodeling experience! We are locally owned and operated and understand the importance of getting the job done right and in a timely manner the first time! We are your one stop shop for all your interior and exterior remodeling needs we will ensure that you're extremely happy before we leave your premises! Give us a call today for your FREE estimate! We look forward to servicing you!

"I rank Landson Construction #1 in the list of contractors we have hired in our 40 years of home ownership. Ari and his team of subcontractors recently completed a challenging remodel of one of our bathrooms--challenging because it is a very small area with limited space. Their finished job looks better than our separate remodel of a larger bathroom completed by one of the big firms that advertises daily on television. Examples: the tile work in our small shower is exceptional, and the vanity/oversized sink is a perfect match that does not dominate the small room. Ari Erickson (no relation to me) offered selections from his preferred vendors, but we had full latitude to shop on our own for all tile and fixtures. He and his subcontractors kept us fully apprised at all stages of the project, arrived promptly throughout the course of the work, responded promptly to our texts and emails, and cleaned up their work area at the end of each day. My highest recommendation: I always seek at least four bids for a major project, but I would forego that process and hire Landson Construction again for future building/remodeling projects, and would encourage friends and family to do the same."

FAQs for addition to existing structure building service projects in Andover, MN

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.
