About UrbanBuilt

UrbanBuilt is a general contracting firm offering residential and commercial construction and renovation to clients in Baltimore and across the Mid-Atlantic. Core to the firm’s success since its founding in 2008 is its focus on keeping clients at the center of each project. UrbanBuilt works closely and communicates regularly with clients so that they are informed and involved throughout the entire project process – from planning and designing to construction and close-out. The firm uses a structured process—from pre-construction to construction then post-construction—to ascertain that clients are aware of their options, are guided through decision-making, and receive a project as they envisioned.

One of the firm’s remarkable tenant improvement projects was provided for Keller Williams Metropolitan. The project involved repurposing an old industrial warehouse into an office building with conference rooms, individual offices, and other modern facilities. To maximize the large height of the structure, the firm added a mezzanine structure for additional offices and converted the main floor to a large lobby and pantry with individual offices at the back end. As the structure had a standing history in the area, UrbanBuilt opted to retain the industrial look with large front doors, exposed beams, and large steel windows. The open floor design offered Keller Williams versatility for future events and gatherings while the availability of individual offices allowed for more private conversations—particularly useful when discussing prices and financing with clients. The firm’s design created the perfect space for the real estate team and their growing clientele.
