The fall & rise of raised beds

Finally, after eight years, my raised vegetable beds have bitten the dust - literally. For the last year the wood has slowly started rotting away. Now the sides have given up the ghost and started to go awol.
Good time to replace them I thought. So I ordered four new beds - 2 x 2.4m long and 2 x 1.8m; the two old 4.8m long beds were too long - they bowed in the middle and took ages to walk round. Lazy? - me!
Last week I cleared away enough soil to put down one bed, with the intention of filling and moving the soil to get the others down and filled in a logical (kinda) manner. Yesterday the beds were delivered and I stood out in the freezing cold treating them with a wood preservative. Now, today, we've got 5cm of snow, the ground is frozen and everything is on hold.
Thank gawd for the conservatory. After clearing out enough rubbish to give me some room, I've started building the beds indoors. I just need to remember, like someone I knew who built a motorcycle in his attic and then couldn't get it out again without partially dismantling it, that I need to ensure I can get them out of the patio doors.
No doubt, despite my excitement to get them finished asap, we'll have another bad winter and I won't be able to start using the beds until May. Good job I've got some frames to start everything off from seed.
