Very nice. Did you make those interlocking 4X4 posts yourself, or was that a kit you purchased?
Oh, no. I just assembled them! They were purchased from Greene's Fence Co. (
https://greenesfence.com) The one I purchased last year is doing great, so I invested in two more this year.
Here's bed #1 from a week ago:
I live in the very wet and warm (zone 8a) Southeast where most wood rots very quickly. We also have termites, so cedar wood is recommended. If I can get five years out of these beds it is well worth the investment.
I became aware of raised bed planting back in the early 1980s, probably from Rodale. I never used boards but just dug trenches for paths, throwing the dirt on the beds. It worked well for many years. I'm older now, can't bust the sod as I did 40 years ago, so I garden "smarter".

When I hit my late 50's, I decided that taller raised beds would be easier for me to work. Since then, all my new raised beds are 16 inches high. I fill the bottom 8-10 inches of the bed with hügelkultur wood, then layers of organic material, then the top 6-8 inches with a topsoil/chicken run compost mixed 1:1.
I discovered Hugelkultur last year. There's a very good YT channel that I binge-watched with a master gardener "Scott", think I first learned about it there. (

I didn't have much wood for the bottom so I used small branches and canna lily stalks. Some of them sprouted

but eventually I pulled them all. On top of the wood and brush I put a thick layer of dry leaves, then partly-rotted leaves/grass clippings, then some peat moss, Blackow, mostly-rotted compost, and some cheap topsoil from Lowe's. It did well, and when the dirt level dropped a couple inches by Autumn I added leaves. When I got to the bottom of the bed I found nothing but dirt, all the branches had totally decomposed! I added some watermelon rinds, they were gone by the time I planted this year. I'm sold!
I don't know how much a cedar wood raised bed that size would cost, but a few years ago I priced out the cost of lumber for just pine boards and it was almost $150 per bed at that time. That makes for some expensive tomatoes, etc....
The price of a 4x8x14" cedar kit wasn't much more than your estimate, but without the investment I probably wouldn't be gardening as much as I am this year.
I live on a lake, and my native topsoil is basically sand. Terrible for growing food. So, my major expense on building new raised beds is that I purchase a trailer full of Red River topsoil for $60 bucks a load. When mixed with chicken run compost, it is enough to fill the top portion of about 4 of these raised beds. It's well worth it to me and still I only end up paying maybe $15.00 per garden bed when I'm done.
We have a sandy clay soil, which needs lots of amendment. When we get mid-summer droughts my flower beds in the ground are like dust, and without adding humus the soil won't hold water.
Enter the compost pile(s)!
We have a third acre in an older suburban area and the yard (not "lawn", "lawn"=grass. Our yard is green and grows) provides us with huge piles of clippings from March to October. We're next to hardwoods on one side, which helps provide us with leaves. Over the last few years we switched from a riding mower to a powered push type with a bagger! My dh dumps the clippings onto a pile which I supplement with cardboard and weeds. I also use the mower to run over piles of leaves from the huge sycamore tree in the front yard.
This year when I set up the two new raised beds I did not buy any soil. I used lots of thick branches, partly-rotted leaves/grass clippings, peat moss, a little remaining Blackow, mostly-rotted compost, wood ashes, and finally dirt from the bottom of the compost pile which I dug from just above the clay soil. I had two bags of peat moss from last year, so I didn't spend money filling the new beds.
Here's a picture of a galvanized panel raised garden bed I made about 4 years ago, long before I got into pallet projects. Anyways, check out that outstanding quality topsoil mixed with my chicken run compost. That's about as good as it gets....
Every year, I mix in fresh chicken run compost into the beds as the hügelkultur bed levels drop as the wood and organic matter decays. The compost I make in the chicken run is better than the compost I used to buy in the big box stores. Every year my raised beds get topped off with fresh compost. I feed the soil, the soil feeds the plants, and the plants feed me.
Mine doesn't have chicken manure, yet. Think about how lovely my gardens will be after I add some litter from the chicken run.
It's satisfying to use what we are given by God/His nature, and see the results.
This probably should have been posted in the gardening area...oh well.
