This project was built and designed by Mike from Oregon Makers. It features two styles of wine storage bins—a full diamond and a half diamond—crafted to maximize space and elevate the style of a wine cellar.
Diamond bins are a classic choice for wine storage because they’re both functional and visually appealing. They accommodate a wide range of bottle sizes and help turn any space, even an awkward one under the stairs, into a refined wine display.

Why Diamond Bins Work
The diamond shape is not just about appearance—it also makes storing bottles of various sizes more efficient. Whether you’re working with standard Bordeaux bottles or larger Champagne styles, this configuration holds them securely without wasted space.
Mike’s project includes two versions: a single diamond bin and a half diamond bin. Both are built to fit specific spots in his cellar layout, and each provides a mix of symmetry and strength for long-term storage.
Starting with the Single Diamond Bin
The first step is constructing the outer frame, or carcass, for the full-size diamond bin. Mike uses pocket hole screws to join the panels, a great option for softwood builds thanks to their coarse threads and ease of use.
The bottom board is secured first and checked for flush alignment along the back before flipping the cabinet. Mike uses spacer boards to ensure even shelf spacing, which is important not only for visual balance but also for air circulation between bottles.
To aid in alignment, quarter-inch drill bits are used to create reference holes. This technique makes it easier to set the shelves accurately before securing them, keeping the finished piece clean and professional-looking.
Centering and Securing the Diamond Grid
Once the frame is built, Mike centers the internal diamond divider using gravity to let the angled pieces settle into position. After fine-tuning the alignment, the sections are clamped in place and fastened securely.
A toe kick is added at the base for aesthetic consistency and a finished look. With all elements locked in, the bin is strong enough to handle a full load of bottles while looking sharp in its cellar setting.
Moving on to the Half Diamond Bin
The second part of the build focuses on a smaller, space-saving version of the design. The half diamond bin is ideal for tight spots or under-stair locations where a full unit wouldn’t fit.
Mike assembles three diamond compartments using square stock and nails them together in opposite directions to create evenly spaced sections. A center-finding ruler helps keep everything aligned, especially when fitting multiple components within a smaller frame.
Once the internal diamonds are in place, a small wedge is added at the top for extra support. This subtle detail adds to the visual polish and helps strengthen the unit as a whole.
Nail and Trim Details for a Clean Finish
To avoid damaging the beveled pieces during assembly, Mike uses a pen nailer to secure the diamonds. This light-touch tool keeps fasteners discreet while preserving the crisp edges of the structure.
Corners are toenail secured into the outer case to further reinforce the bin. This technique ensures that the entire piece can bear weight without racking or tipping over—essential for a storage system that might be fully loaded with bottles.
Practical and Stylish Storage
Diamond bins are popular in wine cellars for good reason. The diagonal layout allows bottles to rest securely while maintaining visual appeal. You can fit a surprising number of bottles in each compartment without them feeling crowded.
This design also offers flexibility. It works well in dedicated wine rooms or tucked into unused spaces, adapting to different needs without requiring a full built-in racking system.
A Budget-Friendly Build
One of the best parts about this project is how cost-effective it is. With basic tools, plywood or softwood boards, and a few fasteners, you can build a high-end-looking storage solution without a high-end price tag.
Mike’s use of pocket screws and bulk materials makes this an efficient build for anyone wanting to replicate it. Whether you’re outfitting a full wine room or just organizing a small collection, this project can scale easily.
Final Thoughts
Mike’s diamond bin project is a great example of how woodworking can combine function and design. Both the single and half diamond bins are straightforward to build and result in a strong, stylish place to store wine.
This is the kind of project that adds real character to a space while offering long-term utility. It’s approachable, repeatable, and makes great use of simple materials in a clever way.
