Raised garden bed 100x20cm – DIY Plan

DIY Plan for building a raised planting bed 100x20cm. This narrow planting bed on legs is a great choice when you want to incorporate gardening in a small space but still have a bit more length for more plants, such as herbs, lettuce, strawberries, or small summer flowers on a patio, balcony, or along a wall. It looks neat and provides a clear growing area at a comfortable working height, without feeling bulky.

The construction is designed for a narrow plastic planter box that is placed inside, making gardening practical and easy to keep organized. The wooden frame acts as a stable support that holds the plastic box in place and gives a more furniture-like impression than a freestanding plastic box. The build consists of straight parts and only straight cuts, so it is easy to assemble and works well even when you want a quick building project with clear instructions.

The wooden box has an open bottom so that excess water can drain out if the plastic box has drainage holes, which reduces the risk of the soil becoming too wet and makes gardening easier to manage over the season. The narrow shape also makes it easier to water, weed, and harvest the entire area.

The PDF includes a complete shopping list, saw/cutting instructions with drawings, and step-by-step assembly instructions, so you can download the digital file and follow a clear plan and manual from the first cut to the finished planting bed. The difficulty level is easy and the building time usually takes 1–2 hours.
