I worked on a blokes Holliday shack at Palm Beach, millionaires row. This bloke owned two places next to each other, his was flat out amazing including the artworks on the walls. Next doors was to be renoed but was pretty crap and for the kids. Anyway one of the jobs I had was to install a soft timber buffer to this steel gadget he parked his Bently on in the garage.He kept scarping the Bently when parking. This steel gadget was the top of a car stacking gadget, below ground in a pit was the Ferrari he parked on top off. Paul, maybe you need some kind of stackable racking for the bikes in the new shed.
