In 2001, the Foundation undertook an in-depth architectural investigation both to determine the configuration of the mansion during the Madison Family's lifetime and to ascertain whether sufficient evidence survived to support a faithful restoration. MCWB was engaged together with a team of architectural historians, headed by Mark R. Wenger, from the Colonial Williamsburg Foundation to conduct this investigation. By June of the following year, it had become clear that the accumulated evidence, gathered during this study, would allow the Foundation to retrieve the home Madison knew with minimum conjecture or speculative reconstruction.
