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."

Managed Renovations engages with our clients using a couple different business models depending on their needs, preferences, and level of desired participation in some of the required tasks involved with most projects. Some of our clients choose to use our unique construction management services business model to build their project that is distinctive from the typical fixed-price general contractor (GC) approach to construction. For those clients we provide fee-based construction management consulting services to schedule, manage (on-site), and review all the work that our clients choose to have us handle for the project. We connect and contract our clients with our seasoned collection of licensed and insured tradesmen and subcontractors (and our own in-house carpenters) that will provide each of their fixed price costs. Alternatively, some of our clients prefer to have their project built using a typical fixed-price general contractor (GC) approach to construction.

"We recently had our kitchen remodeled by Managed Renovations. The experienceâ from start to finishâ was nothing short of amazing and the finished kitchen is spectacular, exceeding our expectations. The Managed Renovations team, Michael and Natalie, and their subcontractorsâ carpenters, electricians, plumbers, and floor installersâ displayed a level of professionalism, craftsmanship, and attention to detail that was extraordinary. They turned a small, poorly designed 1970s kitchen into a large, beautiful, functional space that is now the heart of our home. Although the project involved demolishing walls and removing the existing cabinets, appliances, and flooring (and replacing them with new cabinets, appliances, and flooring), they accomplished this with minimal disruption to our lives, always leaving our home and the work area clean at the end of the day. Managed Renovations communicated with us throughout, (we could also track every aspect of the project online), making sure we were comfortable with every decision. Their recommendations, whether about design elements or vendors, were always â spot on.â There were no surprises. They delivered what they promised when it was promised, completing our kitchen on time and without any unanticipated costs. Managed Renovations' dedication to excellence and customer satisfaction is truly unmatched. If youâ re looking for a general contractor who will deliver outstanding results, look no further than Managed Renovations."

We take great pride in our experience, expertise, quality, and customer service that we provide to meet the consumers' needs. It is our mission to provide excellent workmanship, and complete customer satisfaction from start to completion of a project. In order to understand the needs, and expectations of our customers, we take great care to work, and communicate with every customer in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"Billy and his team carried out a major renovation of our 100 year old home, including a total revamp of our second floor to have a masterbedroom, two bathrooms, a walkin closet and a new second floor deck. The project also included renovation of a room to create a library with built in shelves. To say we are happy with the result would be a major understatement. Billy solved a number of unexpected complications in this old structure and made numerous suggestions to improve the plans. He routinely found significat savings in acquisition of materials and other costs. (Note: in the photos below the ramp wss put in by me for our dog and was not part of the renovation.)"

"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."

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

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite. 

An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
