Stacked Pyramid Planter (ACQ Pressure-Treated Lumber)
Build a stacked, four-tier pyramid planter using ACQ pressure-treated lumber: assemble a rectangular base frame, add X cross-braces, cut angled support legs to form a pyramid on a central 4x4 post, attach four shelf frames, cap the post, and fill tiers with garden soil.

The build, step by step
Cut and Assemble the Base Frame
Cut 2 lengths of 2x4 to 30" and 2 lengths of 2x4 to 27". Fasten them together into a rectangular frame using #8 x 3" deck screws. Pre-drill all holes to prevent splitting. Note: the source diagram draws this frame rotated on its point for illustration, but gives no cut angle for these four pieces (unlike the cross-braces and support legs, which do specify angles) — this guide treats it as a standard square-cut rectangular frame, matching the finished photo below.
Cut the Cross-Braces
Cut a 2x4 to 38" long with a 45° angle at each end (see cut-detail inset). Cut 2 more lengths of 2x4 to 18-1/4", each with a 45° angle at one end. These three pieces will form an X-shaped brace inside the base frame — insert them as shown in the next step.

🔒 Unlocks with the planSafety & disclaimers
- ACQ-treated lumber is more prone to splintering and chipping at a cut edge — wear eye protection and pre-drill every screw hole. (hazard)
- Use a clamp or stop block to hold short angled offcuts rather than hand-holding them near the blade. (hazard)
- Fully support both ends of the board and keep hands clear of the blade when cutting opposing compound angles. (hazard)
- Clamp the assembly to your work surface rather than hand-holding when pre-drilling and driving screws. (hazard)
- This step is top-heavy; a second person is strongly recommended to steady the assembly rather than attempting solo. (hazard)
- Start each pilot hole slowly to establish it before driving deeper; keep off-hand clear of the bit. (hazard)
- The assembled pyramid is awkward to flip alone — get a second person to help turn and steady it. (hazard)
- Standard shop practice — no specific safety concern noted. (info)
- Filling and tamping soil into stacked tiers involves repeated bending and lifting — use good lifting posture and take breaks. (hazard)
Questions builders ask
What type of lumber is specified?
ACQ pressure-treated lumber for posts, supports, and decking boards as listed in the materials table.
Are specific screw quantities provided?
No — screw quantities are not specified by the plan and are flagged as missing.
What saws are needed for angled cuts?
A compound miter saw is recommended for the 45° and compound bevel/angle cuts; a circular or band saw is used for square cuts.
How difficult is this project?
The plan lists it as an intermediate-level woodworking project involving compound cuts and multi-person lifting.
Is soil quantity specified?
No — soil type and quantity are not specified and are flagged as missing.
