    The Preservation Trades Network Presents the 21st Annual
    International Preservation Trades Workshop
    "Makin' It By Hand"

    Detroit Boat Club
    Belle Isle Park
    Detroit, Michigan
    September 8-10, 2017

    This year's IPTW will be the 21st anniversary and we are excited for everyone to join us in Detroit! This year’s event will be held at Belle Isle Park with the Detroit Boat Club as the central location for the event. Belle Isle Park is a recreational island located in the Detroit River between Michigan and Canada. The park opened in 1845 and was designed by famed landscape artist Frederick Law Olmstead. The park is home to amazing architecture, statues, fountains, and manmade lagoons. The Detroit Boat Club was constructed in 1902 in the Mediterranean style and was the home for the oldest boat club in America.  

    The International Preservation Trades Workshop (IPTW) is the only annual gathering of its kind in North America that brings together the foremost practitioners of the traditional trades in a single event. It is dedicated to sharing the skills and knowledge of all the trades employed in the conservation of the built environment. Initiated by PTN in 1997, practitioners of traditional trades from more than a dozen countries have come together to share their knowledge and demonstrate their skills.

    Pre-conference workshops are in the works, focusing on window repair, masonry repairs, and . On Saturday night the yearly dinner and auction will be held, to benefit the PTN Misia Leonard Scholarship Fund. Every IPTW draws a diverse audience of tradespeople, architects, preservationists, students and home owners, and offers unique learning opportunities for people of all ages and skills levels

    We hope you can join us for the 21st anniversary of IPTW!
