Where did you order these beautiful doors with bolts?

The doors are "Balcony Doors" from Le Page. They are the only really 19th century looking doors that are not totally custom that I know of here in the US. They have the traditional narrow stiles and rails, while still having double glazing and good weatherstripping. Le Page is a Quebec company, so that is probably why they continue the french design tradition which is what early glass doors in the US were based on. The hardware, a difficult to find cremone bolt which opens from the outside as well as the inside, is by Von Morris.
These doors are best used in areas that only get occasional use, not main entry doors.

How were the floors finished? Is this waterlox? Beautiful.
