Our new dojo floor is 1200 sqft. consisting of (1300) 3″ cubes, 77 sheets of over lapping plywood, 52 DAX Tatami, and 140′ of finished pine border with 5″ vinyl skirting. The floor is stable and does give-way when thrown. Project management was clearly the largest undertaking and involved weeks of personal effort to ensure all design components met requirements and that all materials were correct and on sight before construction day. Our construction team of seven people built the floor in about six hours. It actually was a lot of fun building it and we took many photos before and during construction for future reflection. Thanks for your support.
