DC Broadstone has designed many large Preston Hollow and Highland Park estate homes. He has also been responsible for massive additions to existing homes, such as the Anton Korn designed home on Preston Road. His virtuosity can also be seen in the renovation and expansion designs he did for the Charles Dilbeck home on Chatham Hill. Here you will see tumble brick details and forms that are indistinguishable from what Charles Dilbeck would have designed himself.
