    Building a raised bed

    Am planning to build a raised bed at the weekend, over the site of an old pond. The pond has been drained and pretty much filled with rubble, hardcore, stones etc.

    My plan is to cement 4 posts in the corners, then nail/screw/coach bolt some planks of wood into the posts, building them up a layer at a time. It's about 6ft x 4ft. Not really sure of what sizes post/planks to go for. Obviously it will be filled with soil so there will be plenty of weight in there, am planning on going up to about 60/70cm high and don't want the wood coming apart/breaking under the weight.

    Any tips?

    pressure treated wood, 90x90 posts and wood from the decking section will be perfect for the job

    you could use railway sleepers to make a wall ?

    Thanks, the wife's not keen on the 'ridged' look of decking, but similar dimensions would be ok though?

    Might look at scaffold boards rather than sleepers, anybody used them or have ideas where to get some, £7.50 on e-bay

    stacked timber posts

    you could buy 3x3 or 4x4 posts of the required length pressure treated

    the added bonus is no foundations, just long bolt them together on the ground and fill with dirt, and built in drainage underneath already

    Wickes might have some in if you have a local one.

    Do you mean for the 'walls'?

    Thanks, i saw that website but it was making my head hurt, no real logic and i was just clicking on ones with no idea whether it would be something like what i wanted to do!!

    yes the design you said looked nice, the walls are the entire thing, no posts or foundations needed

    I see, yeah i suppose that would be an idea, would the bolt have to go through all of them from top to bottom? Not sure i would be able to get it 60/70cm if so

    Banned

    no not top to bottom

    ends and each layer to the last with big nails, quick work then

    or you have to mess with drill holes lining up and threaded bar and nuts that you cant get a spanner on
