Bent Palm is a complete residential design build company specializing in decks, porches, patios, fire-pits, outdoor kitchens, and more. We have a professional team of specialists that are ready to create a custom plan for your individual needs. Our innovative 3D designs are created to complement the aesthetic of your home and natural surroundings of your property. At Bent Palm, we love what we do and are confident that you will appreciate working with a professional design build company giving each customer the individual attention from the first design consultation to project completion.

"Bent Palm gave me a great quote and completed the project on time. From my perspective, the other key component is that he was able to get approval of all of the various inspections by Montgomery County Maryland on time. Obviously Bent Palm has an ongoing relationship with the county building inspectors and the project was constructed properly and on time. Another reason that I’m giving Ben Palm a five star evaluation is because a previous contractor informed me that the only way I could put a screened in porch on the back of my house is to file for a variance. Bent Palm built my screened in porch with no variance and approved by the county. Further the quality of the work was outstanding. Not only did he have contractors to do carpentry work, but he had a great electrician and an even better painter. At the end of the day, the project turned out fantastic."

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."

Addition to existing structure building services FAQs

Converting an existing space into a laundry room is more affordable than building a new addition. While new additions start at $5,000, renovating an existing space for laundry use can begin at $1,300. 

Your specific costs will depend on whether plumbing and electrical connections exist nearby, the quality of finishes you select, and whether any structural modifications are needed. Always budget extra for unexpected issues, particularly in older homes where hidden problems might surface during renovation.

The smallest practical size for a new laundry room addition is 35 square feet, which provides enough space for basic appliances and minimal storage. For renovations utilizing existing space, smaller footprints might work with space-saving solutions like stacked appliances. 

A standard-sized laundry room of 60 square feet offers more comfort and functionality, allowing for counter space and storage cabinets. The optimal size depends on your household needs and available space.

Yes, adding a laundry room requires several permits, particularly for new additions. You'll need building permits, plus specific permits for electrical work, plumbing installations, and possibly HVAC modifications. 

Requirements vary significantly by municipality, so consulting with your local building department before starting work is essential. Proceeding without proper permits can result in fines, mandatory removal of completed work, and complications when selling your property.

The timeline for completing a laundry room addition varies based on project complexity, contractor availability, and permit processing times. Factors that can extend the schedule include material delivery delays, weather conditions, and unforeseen structural issues discovered during construction. 

Renovating an existing space often requires less time than building a completely new addition. Working with an experienced contractor who can coordinate various tradespeople efficiently helps keep your project on schedule.
