Raised flower bed/ veg garden or wood to make one! (Ifton Heath SY11)

HI I am fairly recently moved to st martins which we love, I was excited to move to a house with a garden. However the soil here in this area is all clay. Therefore I want to either build / or restore a raised flower bed/ veg plot so I can start off with really good soil for my veggies... does not matter if it needs a bit of tlc... so if there happens to be one or two veg boxes someone needs to find a home for OR if you have suitable bits of wood I can put together!- please let me know ;)

thanks!

Joy
