This project was built and designed by Izzy Swan.
Izzy repurposes a classic folding bookcase table into a compact indoor garden designed for seed propagation and microgreens.
The build focuses on a simple parallelogram pivot mechanism, thoughtful joinery, and a layout that makes hydroponics and everyday plant care more ergonomic.

Design
The core idea is elegantly simple: two side panels, a few stretchers, shelf brackets that act as a parallelogram, and a bottom shelf for a reservoir.
This arrangement lets the unit fold up like a bookcase or open flat like a shallow table while leaving room for tubing and wiring needed for hydroponics.
Lumber Prep
Rather than a single thick panel, Izzy laminates two sheets of half-inch plywood for the legs to gain extra stiffness and strength without complicating the build.
He also cuts pockets to receive the stretchers and favors a 40‑tooth Prestige table saw blade for consistent plywood cuts, emphasizing steady feed rate over blade changes.
Joinery and Fastening
The moving shelves pivot on stanchions and are spaced using washers to maintain separation and free motion, with some washers temporarily glued in place using 2P‑10 and an activator to streamline assembly.
Izzy taps threads with a 3/8″ drill in the alder stanchions and uses bolts carefully snugged (not over‑tightened), plus predrilled holes and PowerPro screws into end grain to prevent splitting.
Assembly Details and Limits
Small details keep the mechanism working smoothly: chamfered stretchers clear glue squeeze‑out and make the fit forgiving during assembly, while cantilever pieces set the travel limits and secure the bookcase to its base.
The base can be a simple, solid platform—Izzy used CNC parts for speed, but basic 4×4 posts or a straightforward box base work just as well.
Shaping and Fit
Chamfers and careful clearance work make the moving parts feel less fussy and reduce binding as the unit opens and closes.
The shelves can be fitted tightly to act as a table surface if desired, or left with small gaps to accommodate grow lights, tubing, or wiring for hydro setups.
Hydroponics and Ergonomics
Izzy configures this build as a seed propagation and microgreen station with lights mounted above and a reservoir on the bottom shelf, which keeps all growing elements consolidated and reachable.
The ability to pull the unit away from the wall and tilt it down lets the user work at a comfortable height for planting, watering, and harvesting.
Lessons and Adaptability
The project is approachable and not much more difficult than a standard bookshelf, but it introduces a useful moving‑shelf mechanism that can be adapted for tables, workstations, or other space‑saving furniture.
Techniques shown—laminating plywood for strength, tapping threads for quick assembly, and using simple limits—are easy to adapt to different scales or other indoor gardening setups.
