Paul Janssen

M.A.A.T.O., B. Arch., B.Tech.

Paul’s passion for construction was evident from a young age. His parents saved pictures of him working at a site near his home when he was around 9 or 10, working and helping with construction. He worked on construction sites during his high school years and his passion switched to design and architecture some time during his highschool years. He did his first design, for an addition, for a local contractor at the age of 16. Paul ended up studying Architecture at Ryerson where he obtained his Bachelor of Technology in Architectural Science and then went south of the border to study at Lawrence Tech University for his Bachelor of Architecture. Upon completion of his post secondary education Paul decided fairly quickly that an indoor office job was not something he’d be comfortable with, in the long run, so he started his construction company at the age of 24 and married his highschool sweetheart the same year.

Paul’s family settled in the Orangeville area and they currently work and play in the Dufferin County area. Along with Margaret, his wife, he established Janssen Design & Construction and over the next few years added a few different branches to the
business to provide better services to their clients. As the company grew and as Paul wanted to focus more on the customer experience the company evolved to JDC Custom Homes Inc and the different branches of the company were amalgamated into one.  Paul’s passion has always been in fulfilling their clients’ dreams of home ownership and having the home they’ve always longed for. Whether it’s a brand new modest home, addition, renovation or a luxury and energy efficient home with home theatre, indoor pool, entertainment areas and/or personal fitness centre, JDC takes pride in being capable in designing and building for a diverse set of local and international clients. 

The JDC team, consisting of local staff/trades & suppliers, take pride in providing a quality of finishes and detail that’s not common in the industry any more. An ‘old school’ mentality of ‘treat others as you want to be treated yourself’ is top priority and JDC will not cut corners to ‘cheapen’ their product. After being a ‘hands-on’ owner for many years the company has grown so much that Paul’s time is spent mostly on sales and quality control and perfecting the business model to create a construction business that will excel above the status quo and create a client journey that’s second to none. JDC has won the Business Excellence Awards for Home Builder Excellence several times, is a board member of the local Board of Trade, a member of Tarion, RenoMark and Paul is the president of the Greater Dufferin Home Builders’ Association for the second time in his career in 2019-2021. As you can tell, Paul is a firm believer in giving back to the community in which they live and work and has extreme pleasure in participating in local community events.

JDC has now grown in size and can offer all aspects of residential construction from design to move in condition, as well as project management and they now also offer a maintenance program to have them look after their clients’ investment and keep it in top performing shape for years to come.
