Wiedemann Architects has worked with O’Neill Development on numerous projects over the past twenty years, ranging from several new homes to sensitive renovations and seamless additions to historic homes. They consistently bring the highest quality of both project management and quality of craftsmanship to each project. They are known for their timely completion of the work and dedication to service to our clients. Their exceptional superintendents and subcontractors work closely as a team to complete the work on time and on budget. I recommend them highly and without reservation.

My company has worked for O'Neill Development on projects ranging in scope from small additions, to multimillion dollar homes. In every case they have provided impressive customer service to their clients, and provide some of the highest quality work in the area. We work with a large number of area General Contractors, and our experience has been that nobody does it better, or is more honest with their clients than they are.

The O'neills are not just builders, they are artists and it shows on every one of their jobs. The architecture is carefully chosen and they have a team of old school, carpenters, project managers, and other technicians that run things the way a job should be run, ie confidently, competently, and thoroughly. Brendan brings his artistic eye to each plan and "boring" has no place in the finished product. We have been doing independent quality control services for O'Neill for about 10 years or more. We look at every component including HVAC, Electric, plumbing, structure, exterior finishes, and final finishes If there is one distinguishing characteristic of their work it is that we find the latest technical innovations combined with the best of the old construction techniques, that is a rare combination these days.

Over the past 25 years my firm has worked with O’Neill Development on more than 20 projects ranging from modest renovations to projects of considerable scope, sophistication and complexity. They have brought a dependable team of high quality craftspeople and subcontractors to each of our projects. They stand behind their work and have been fair and accommodating in their dealings with our clients. I look forward to working with them in the years ahead.

I have worked with O'Neill Development for over twenty years on both new homes and renovations. By every standard -- quality of workmanship, timely completion of work, and service after completion --they are at the top of the list. Because of that and because of the quality of of their job superintendents and subcontractors, they have become our go-to partner in all of our high performance and Passive House projects.
