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."

We are passionate about our client relationships and this is reflected in all that we do. From the in-house design process, interior and exterior customization and artisanal craftsmanship to the professional management and accurate fixed pricing, our aim is your total satisfaction with your new home, architectural restoration or home remodeling project. 

"I am writing to formally express my deep dissatisfaction with the recent retaining wall replacement project completed by John Krause Construction (JKC) at my property. After reading positive reviews and receiving an estimate that, although over my budget, seemed reasonable for the work involved, I made the decision to hire JKC. Unfortunately, this has proven to be a significant mistake, and I am left extremely disappointed with both the quality of work and the overall experience. Here are the main issues I encountered: 1. Unprofessional Behavior: The crew exhibited unacceptable behavior while working on my property. Not only did I witness them disposing of bodily fluids on-site, but they were also disrespectful and dismissive. when I raised concerns no response was received. I now smell urine when entering and exiting my garage. 2. Unresponsive Ownership: I have attempted to reach out to the owner multiple times to address these concerns and resolve the issues, but my messages have been met with silence. This lack of communication is incredibly frustrating and has only added to my disappointment. The owner refused to speak on the phone since the owner was made aware of the call being recorded. 3. Property Damage: During the construction process, my property was left damaged in multiple areas. This included e.g., landscaping destruction, equipment damage. Personal crew members vehicles being driven through my yard leaving deep tire marks damage. 4. Subpar Quality of Work: Despite the high cost of the project, the final result does not meet the standards outlined in the estimate or contract. No proper grading was completed. Every time it rains pools of water sits in front and behind the wall. The response received was. “we have passed all inspections.  There will be some water pooling while it is settling still. Plus the fact of the hard rain today, it will happen.” The wall has been completed for 2 months. Given the extensive problems, stress and anxiety I have faced. I do not recommend John Krause Construction."

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