"We had an exceptional experience with Johnathan, Jeffry, and their team. Their professionalism, friendliness, and expertise stood out from the start to the finish of our basement project. The process was smooth, transparent, and free of surprises, with clear cost and material outlines. We appreciated their flexibility in allowing us to choose different materials and only charging the price difference. When we added more work mid-project, they were accommodating and maintained high-quality workmanship. They provided a wide selection of cabinets, flooring, tiles, mirrors, and bathroom faucets. The project was completed on time and within budget. We are thrilled with the results and plan to work with them again. Everyone who has seen our basement loves it! Overall, we highly recommend their services."

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."

"When I started down the path of remodeling my 2 outdated bathrooms, I had no idea what to expect.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."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
