"When I started down the path of remodeling my 2 outdated bathrooms, I had no idea what to expect. My two main criteria were fair price and good workmanship. Abode Construction delivered this and more! Scott provides top notch work, respectful and capable crew, quality customer care, and advice, all for a competitive price. His team, from the estimate to changes for the project through completion of the bathrooms, make the client feel valued. Did everything go as planned? Absolutely not. Some events were unavoidable (e.g. supply delays) but some could have been avoided. However, Scott made sure that we were whole at the end of the day and made good on his 100% guaranteed satisfaction. I now have two updated, modern bathrooms that we all LOVE! I will be using Abode Construction for future projects and highly recommend them to others."

We pride our company on reliability, great communication, integrity, and quality work. We strongly believe in giving our absolute best in all of our projects no matter how big or small. We are experts in our trade and will always keep you educated on your particular task or project. We look forward to earning your business!

"All the people at Elevate Design and Build were amazing and a pleasure to work with. We doubled the size of our house including tripling the size of the kitchen, knocking out walls to create an open floor plan and added a three car garage with home office over the garage. They even recommended modifications to our original blueprints which were excellent. All their workers friendly and did a first class job. Went totally above and beyond our expectations. One year later we have not had one single problem with any of the work. Total integrity. If any issue came up, the company absorbed the cost - not the customer. Everything they did was done perfectly. We didn't have a single issue or complaint during the entire process. I give them my highest personal recommendation. I would never use anyone else."

"Overall, our experience was positive. The pricing was very competitive, and the quality of the products met our expectations. Communication, however, could have been more consistent. Responses to our inquiries were sometimes delayed, and we occasionally received messages late at night. Additionally, working with multiple contacts made the process feel a bit disorganized at times. That said, when communication did happen, they were helpful and responsive. With a bit more coordination, this would have been a near perfect experience."

FAQs for addition to existing structure building service projects in Germantown, MD

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.
