hello all, had such an epic day yesterday up at the soul patch but was
going to see if anyone had any canny and most importantly cheap ideas
of how to create large raised beds. i am thinking 2 20ftx10ft beds so
quite a lot of material needed. any thoughts well appreciated!

Why on earth would you make them 10ft wide? They should be no wider than
you can reach into the centre without standing on the bed, usually 3 to 4
ft. This will have a longer perimeter for the same area and so cost more
than 10ft wide but you don't want to walk or have to push a barrow over your
bed.

New materials like concrete blocks or timber that is durable in contact with
the soil tends to be expensive. If you can get such second-hand you may
save much.

Corrugated iron (eg colorbond) is cheaper and works well but has the
disadvantage that you cannot sit on it. You will still need to put an
edging strip along the top all the same for safety.

How high do they have to be? If only short maybe no sides are required.
Where will you get the soil to fill them?
