Bike shed solutions/ideas?

[nick crisp]

I would remove most of the jamb, maybe leave 100mm at each side to screw it down, then get some scaffold boards to make a ramp about 4 wide, batterns on the underside to keep them together and bed them on the gravel so the doors clear them, treat them with preservitive and they should last years. You can buy 2nds for around £1 a foot?

But the doors drop almost to the level of the concrete base, i.e., beyond the top surface of the shed floor level, so you'd still have an inch or more of rise to get up. So, short of taking a bit off the bottom of the doors....Hmmmm...... :\
