About O’Neill Development

O’Neill Development is a construction, remodeling and development firm that has been active in Maryland, Virginia, Washington D.C. and the Eastern Shore since 1975. The company has custom built or remodeled over 350 homes of various sizes including four residential themed communities. O’Neill has been recognized for its high-quality custom work in both national and local publications and has received awards of excellence for its historic restoration and urban infill work from the State of Maryland and from a number of local jurisdictions. O’Neill was the first in this region to build to Passive House standards and remains committed to best practices in green building.

O’Neill Development specializes in custom residential work, providing extensive pre-construction and construction services. For the client, this means a broad band of help in budgeting, architect selection, design development, and problem solving during the critical early stages of planning; careful management by agenda and site control during the construction period; and thorough after-market service.

In all custom work performed, O’Neill believes in teamwork and transparency, particularly stressing the importance of a strong relationship among the client, architect, builder and subcontractor. It is our firm belief that this close connection among all parties is absolutely necessary for a successful project. The company continually evaluates subcontractors and suppliers and selects a team which meet our required nexus of quality, dependability and fair pricing.
