The (old) architectural drawings upon which Castle Victorian was based provided sufficent details to establish an authentic floor plan and exterior elevations. However, these plans did not detail interior finishes. For guidance, we relied upon a number of books on Victorian homes and Victorian living. To these resources, we added our personal observations from visiting museum houses in various locations around the country. Our goal was to match the interior finish with the era of the original 1885 house. The year 1885 was considered the latter phase of the Victorian architectural era. From our research, we chose to construct Castle Victorian with 12-foot ceilings on the main floor and 11-foot ceilings on the second floor. We also chose to set the door height at 8-feet, and mounted "picture-rail" moulding around the rooms to facilitate the hanging of paintings in the traditional manner of the day. In 1885, electricity was only available in very limited locations; for this reason, we chose to use light fixtures that are based on gaslight designs. Three rooms feature ceiling medallions, and two rooms feature detailed, plaster crown mouldings.

The oak floors are random-width Russian white oak. We purchased the flooring from a company that specialized in reclaimed antique wood. However, unlike most reclaimed wood, this flooring had never been used. It was milled from thick boards that had been harvested over one hundred years ago in Russia; no kidding! A company in Vermont, "Mountain Lumber" bought 60,000 board-feet of this material and 2,200 square feet ended up in our Victorian house. The wood floors are throughout the house and they have proven to be beautiful and durable.
