With the exception of a Carrera  grandstand all my buildings are built from photo cardboard . More information at tips and tricks. All beginners I can recommended the following websites: www.carrera4fun.de  and www.pedemann.npage.de. Inspired by these pages I started to build my own buildings. The results in form of grandstands, a pit lane, a Control Tower inc.VIP area, a SC24.com lounge, a media center, commentators cabins, a winner podium and a score board you can see here.
