Making your private compost is a unbelievable strategy to reduce waste, and create free pure fertilizer to your yard! In case you’re eager on establishing a model new compost pile, you’ve come to the appropriate place. This tutorial will stroll you via the step-by-step course of we took to assemble a compost bin – along with the gives needed, our DIY compost bin design and plans, and tons of photographs to info you alongside the easiest way. There is a condensed printable mannequin on the end of this publish too!
We’ve been composting for over a decade using a variety of smaller strategies. However the newest addition of 4 mini-donkeys to our homestead motivated us to lastly assemble the large 3-bay compost bin of our objectives. They generate quite a few manure, which is ready to make stellar compost!
As quickly as we acquired right here up with the design, it was pretty simple to assemble the compost bin… so we’ve already achieved the hardest half for you! It stroke a chord in my memory quite a few developing a raised yard mattress since we used many comparable provides and steps. Even if you don’t observe our exact design, I hope you uncover this useful as a primary info and inspiration!

The Biggest Compost Bin Measurement
Compost bins can be found in lots of shapes, sizes, and varieties. On our homestead, we use the whole thing from a compact worm bin and compost tumblers to massive 3-bay compost bins.
To make a standard passive or gradual compost pile, it’s most interesting to supply not lower than a three-by-three foot home. However for optimum microbial train and decomposition, a compost pile should be not lower than 4x4x4 toes. That allows for enough supplies to be piled as a lot as make a scorching compost pile too, which is what we plan to do!
If home permits, it’s ideally suited to supply an area for quite a few piles (usually separated by partitions or “bays”) so that the compost may very well be rotated and turned. A conventional 3-bay compost system consists of 1 half to actively add current supplies to, one half that’s recurrently being turned nevertheless not added to, and a final half to hold accomplished compost – ready and able to make use of in your yard.
In proper this second’s lesson we’ll assemble a compost bin with 3 bays, though you can tweak this tutorial to make solely a single bay, two-bay, or smaller 3-bay compost bin as correctly. We used to have solely a single bin at our outdated metropolis homestead – and it did the job!




Our New Compost Bin Plans and Design
Underneath are photographs and drawings of our 3-bay compost design. The compost bin choices three 4x4x4 bays, and takes up a whole footprint of about 12×4 toes. I’ve moreover included a bonus drawing of a second simplified compost bin design that you should use if you select (however phrase the lumber dimensions and instructions will fluctuate barely).
Our compost bin design choices removable face boards which may be added by tracks or slots alongside the frontside of each bay. By doing so, you can pile up the compost good and extreme barely than letting it spill out the in another case open entrance aspect. This helps maximize the use and functionality of the compost bin, and will also be optimum for quick decomposition and scorching composting!








Donkeys, Gates, and Design Flexibility
Please phrase that we designed our DIY compost bin with a few very specific needs in ideas. Together with being sturdy, sensible, and fascinating, we’d have appreciated our compost to be donkey-proof!
Our 4 250-pound miniature donkeys LOVE to rub up in opposition to picket posts and constructions, however we’d have appreciated to assemble the compost bin of their pasture area for easy manure administration. So, we chosen additional sturdy lumber and as well as added further assist braces to withstand their rubbing.
Together with the removable entrance picket slats, we moreover added hinged gates to the doorway aspect of each compost bay to keep up the donkeys out (which we’re capable of moreover take absolutely off and on with ease). As a bonus, the gates will deter one other critter train as correctly!
That said, we had to ensure the width of each compost bay (or home between the partitions) was very precise, as a result of the gates needed to go well with on the doorway aspect of each. The partitions moreover wanted to be very straight so the gates would possibly cling sq. and diploma. Though they’re fairly delicate, the gates do put added weight and pressure on the compost bin partitions, so I solely advocate together with them if compulsory.
Since most of you folks acquired’t have such specific quirks to work spherical, be joyful to be further versatile and inventive in your compost bin design and assemble! As an illustration, it’s not a large deal in case your bays aren’t all exactly the an identical measurement or fully diploma.






Gives Wished to Assemble a Compost Bin
Listed beneath are the devices and gives we used to assemble a compost bin, along with some totally different provides you should use too. See the printable “how-to” on the end of this publish for a condensed gives guidelines and instructions.
Devices
- Observed
- Power Drill
- Diploma
- Aviation snips, for slicing {{hardware}} materials
- Measuring tape
{{Hardware}}
- Longer screws: 2 ½ to 3-inch outside picket screws or decking screws to connect the 2x6s (or 2x4s) to the 4×4 corners.
- Shorter screws: 1-inch or 1-1/4″ huge head cabinet screws to attach the {{hardware}} materials to the 2×6 partitions
- Fence rail brackets (12 full) to connect the 2x6s to the 2x4s on the two inside partitions of the compost bin
- Screws to attach brackets: 1 inch or 1/4″ inch screws – each use the an identical cabinet screws as above or shorter picket/deck screws
- Non-obligatory: 4 flat nook braces (one for each wall) for added stability.
- Non-obligatory: 4-foot steel tube gates, one for the doorway of each bay. (The gates embrace J-bolt hinges to carry them, nevertheless you’ll need a 1/2″ drill bit to make pilot holes for the J-bolts.)
Lumber
- We used redwood 2×6 lumber to assemble our compost bin, as we wanted one factor additional sturdy and sturdy that will stand the examine of time (and donkeys). You may moreover use 2×4 boards, though you’d want to add an additional horizontal row of boards (4 rows instead of three like we did) so take that into consideration everytime you’re calculating lumber needs. Redwood is unquestionably accessible proper right here in California, though cedar is one different good sturdy totally different.
- We chosen 8 foot prolonged boards to assemble our compost bin because of a) that’s what slot in our Subaru, and b) it divides up correctly with out waste (as compared with using 10 ft boards for 4-foot partitions as an illustration).
- In full, we’d have appreciated eleven 8-foot 2x6s for this compost bin design. Nonetheless, 12 foot boards would work even greater for the underside! Meaning, you should use three sturdy 12-foot prolonged boards alongside the once more, plus six 8-foot boards for the partitions instead.
- 4 8-foot 4×4 boards (decrease in half) for the nook helps or end of each wall
- Three 8-foot 2x4s (decrease in half) to create the slots that the removable face boards will slide into alongside the doorway aspect of each bin.
- Removable face boards: 1×12 inch pine picket boards (which truly measure ¾” inch thick). Using three per bay, they stack as a lot as create a pleasing 3-foot tall entrance wall. We used 5 8-foot prolonged boards full, decrease roughly in half. Or, use 9 of these four-foot boards and trim them if needed. Wait to measure and decrease the boards for each bay until after you assemble the compost bin!


Wire Mesh
Compost should breathe! To produce enough airflow, we constructed our compost bin with minimal picket and lined the partitions with {{hardware}} materials instead. You’ll need about 25 to 30 toes of 4-foot huge 1/2″ {{hardware}} materials for our measurement bin.
{{Hardware}} materials is ideally suited to a compost bin design for quite a few causes: a) it stays taught and acquired’t bend or bow out beneath the burden of the compost b) the gaps are small enough to hold little bits of compost IN whereas moreover preserving vermin OUT, and c) it’s galvanized and acquired’t rust, so it’ll remaining endlessly!
You may moreover use rooster wire to assemble a compost bin, though if you do, I’d add further picket slats throughout the outside to produce further assist. Moreover take notice rooster wire is vulnerable to degrading over time, and vermin can match through the holes.


INSTRUCTIONS
Step 1: Choose a Location + Web site Prep
The place to position a compost bin? A compost pile should be located shut enough to your yard or dwelling for simple accessibility and use, nevertheless not so close to home that potential odors or flies may very well be an issue. (Though a appropriately maintained compost pile should not stink!)
The compost bin should even be located on fairly diploma ground. As a result of it’s pretty big and heavy, we constructed our compost bin in place and used a landscaping rake to scrub out the underside ground first. You may moreover assemble the smaller aspect partitions on a flat work ground elsewhere, then assemble the compost bin in its final location.
Lastly, it’s most interesting to depart the underside of the compost bin open to the native soil beneath (versus together with panorama materials, wire, or totally different provides beneath it). This leaves different for drainage, useful microbe alternate, pure earthworm train, and as well as makes it easier to indicate or scoop out the compost with out getting snagged up on one factor on the underside.
FAQ: Must a compost pile be throughout the photo voltaic or shade?
A compost pile may very well be located in each photo voltaic or shade, and there are professionals and cons to each. A sunny location will help to warmth the compost, dashing up decomposition correctly. However quite a few photo voltaic will even dry out the pile further readily, requiring it to be watered further normally as needed. Inside the shade, the compost will maintain good and moist nevertheless will break down slower.


Step 2: Measure and Reduce Wood
Subsequent, acquire your whole lumber, take and mark measurements, and decrease the boards to the required measurement to your DIY compost bin design.
- Corners: Reduce the 4×4 corners to 4 toes tall (e.g. decrease the 8-foot 4x4s in half)
- Once more: In case you’re using 12 foot boards, the once more wall boards acquired’t need to be decrease the least bit. Since we used 8 foot boards, we left three of them full at 8 toes, then decrease a pair to create the three further 4-foot boards needed for the once more of bay 3.
- Partitions: Though each bay is about 4×4 toes, we didn’t decrease all of the aspect wall boards exactly to 4 toes. On account of the two inside partitions even have the added dimension of a 4×4 on each end, we decrease six eight-foot boards at 51.5 inches that had been used for the two end partitions (the entire depth of the finished compost bin). That left behind 6 objects that had been 44.5 inches to utilize for the two inside partitions – which moreover equals 51.5 inches as quickly because the 4x4s are added to each end (since 4x4s actually measure 3.5 by 3.5 inches). See image beneath.






Step 3: Assemble Compost Bin Outer Partitions
- Begin by developing one end or outer wall of the compost bin. For our compost bin design, these had been the 51.5” sections.
- We uncover it is best to place two 4×4 nook objects on a flat ground (spaced the width of the wall), then lay the three horizontal 2×6 boards all through the 4x4s – one on the prime, one on the bottom, and one spaced halfway in between. Maintain the ends of the 2×6 flush with the sides of the 4×4. See photographs beneath.
- Subsequent, add 2 prolonged screws to the ends of each 2×6, securing them to the 4×4 beneath.
- Repeat the an identical course of for the second outer wall.
TIP: Sooner than securing with screws, look at that the whole thing is sq. using a carpenter sq. or measuring tape. With a tape, I measure the hole between the 4x4s at every the best and bottom to ensure they’re equal. I moreover like to help preserve the whole thing tight in place whereas Aaron screws the whole thing in.




Step 4: Arrange Once more
- Upon getting the two end partitions of the compost bin assembled, stand them up and add the prolonged boards alongside the once more to create an unlimited U-shape. Try and set the whole thing up the place you want it to stay future, as a result of the compost bin will get heavier and tougher to maneuver the additional you add to it.
- It’s needed to keep up the 2x6s on the floor of the bin, with the 4×4 corners going by the inside of the bin. (The 4x4s current part of the lip or edge that the removable entrance boards will tuck into.) Moreover look at that the partitions and once more boards are comparatively diploma as you go – entrance to once more, and aspect to aspect.
- As soon as extra, this half is additional easy using 12 foot boards. Merely add the 12 foot boards between each end wall, securing them to the nook 4x4s.
- Since we constructed our compost bin with 8 foot boards instead, we wanted to assemble the underside in sections by connecting 8 foot boards and 4 foot boards collectively throughout the heart with an additional 4×4 to create the entire 12 toes. (That further 4×4 will change into the underside for one coronary heart wall)










Step 5: Add Inner Partitions
Subsequent the compost bin needs two inside partitions, spaced 4 toes apart. Ours are 43.5″ apart when measuring inside-to-inside of each 4×4, as confirmed in our design drawing.
In case you’d like, you can go ahead to Step 6 and add {{hardware}} materials to the once more and aspect partitions first (as you’ll see we did throughout the photographs beneath), as long as the {{hardware}} materials acquired’t impede the place you’re attaching the two inside partitions.
To assemble the compost bin inside partitions, you can each assemble them individually (similar to the outer partitions) after which join them to the once more wall of the bin, or assemble them onto the once more boards in-place. We chosen to assemble them in-place since considered one of many inside wall 4x4s was already linked to the once more.








Step 6: Add {{Hardware}} Materials
- After developing the compost bin physique, it’s time in order so as to add mesh wire ({{hardware}} materials) alongside the inside of the partitions and once more.
- Be careful when working with {{hardware}} materials – it could properly merely scratch and poke you!
- Comparatively than wrapping a whole bay in {{hardware}} materials instantly, we found it was finest to measure, decrease, and repair the {{hardware}} materials to each wall one-by-one.
- It’s efficient to overlap the {{hardware}} materials onto the 4x4s alongside the once more wall and corners, nevertheless protect it flush with the 4×4 on the doorway aspect so additional {{hardware}} materials acquired’t block the slot the place the removable entrance boards will go. See photographs beneath.
- Protected the {{hardware}} materials to the picket using 1” cabinet screws, pinching a nook a part of the wire mesh beneath the huge head of the screw. Add screws in quite a few places.
TIP: Since {{hardware}} materials tends to bubble, I found it was finest to hold the decrease piece of {{hardware}} materials in place, straight and centered on the wall the place we wanted it. Then we secured it with screws alongside the heart first (one in each wall board) and slowly labored our means out, together with screws from the center within the route of every corners of the partitions, holding or pulling the {{hardware}} materials taught and clear as we went.








Step 7: Removable Face Boards
Now it’s time to create the slots or “tracks” for the removable entrance boards to slide into.
- Add a 2×4 vertically to the inside wall of each bay – 2 per bay, or 6 full. See photographs beneath.
- Use screws to protected each 2×4 vertically about 1 inch to 1.25 inches once more from 4×4 on the doorway of each wall. We used “1-inch” thick face boards, nevertheless their true measurement is ¾ thick. The ¼ to ½ inch gap gives us enough wiggle room to easily get the boards in and out (leaving room for any swelling), nevertheless with out lots additional home that the boards can fall in entrance or behind one another.
- Measure to ensure the spacing is fairly straight and even alongside the whole dimension between the 2×4 and 4×4 sooner than securing them, so the removable face boards can switch simply up and down the observe.
- Wait to cut the removable face boards until the compost bin and tracks are absolutely assembled! Measure and phrase the scale of the doorway slot for each bay. We found that the width of our bays assorted barely, requiring us to cut personalized boards of assorted lengths to go well with each bay (3 per bay). I added a no 1, 2, or 3 to the once more of each board to easily protect observe.
TIP: When measuring and slicing the face boards, give your self a little bit bit little little bit of wiggle room. Reduce them prolonged enough in order that they’ll maintain tucked into the required observe, nevertheless not so prolonged that they’ll be tight and hard to get in and out.














Step 8: Ending Touches
At this degree, your new DIY compost bin is principally full and in a position to make use of! Nonetheless, we chosen in order so as to add a few ending touches to ours.
- To current the partitions added stability (for the donkeys), we added an 8” flat nook brace to the best of each wall – or 4 full.
- We moreover put in lightweight 4-foot Behlen Nation steel tube gates on the doorway of each bay.
They’re secured closed to the 4x4s with a simple eye hook and carabiner kind latch. In case you’ve under no circumstances hung gates on J-bolts sooner than, I extraordinarily advocate watching this tutorial. Nonetheless, we put within the J-bolts straight out of the doorway of the 4×4, not on the sides. We moreover saved every J-bolts going by UP intentionally, so we would merely increase and take the gates off if needed – equal to as soon as we’re turning the piles from one bay to the following. - For added vermin and pest security (if needed), you possibly can moreover assemble and repair a hinged lid on prime of each bay, equal to with picket and {{hardware}} materials.
- I moreover chosen to stain the pine entrance boards (outward going by aspect solely) to help the sunshine picket combine in greater with the final design.








And that’s the best way it’s achieved.
That, my mates, is how we constructed our new compost bin. I do know that was most probably a lot to absorb, nevertheless I optimistic hope the added particulars and pictures made it easier to know! Please inform us if you’ve acquired any questions throughout the suggestions and we’d be comfy to help.
Subsequent, chances are high you will be questioning… how do I actually USE this issue? I promise I will observe up rapidly with a info on how one can use a 3-bay compost bin, along with how one could make a scorching compost pile. Inside the meantime, don’t miss the related articles listed beneath. Moreover please take into consideration sharing or pinning this publish if you found it useful, and depart a consider! Thanks lots for finding out. Happy composting!
