This project was built and designed by Sam Macy. It’s a clean and practical raised garden bed made with hemlock, offering a rustic look and sturdy structure that fits into any outdoor space.
Whether you’re a seasoned gardener or starting fresh, a raised bed makes planting easier and more organized. It’s also a great weekend project that adds visual appeal to your yard.

Choosing the Right Wood
Sam chose durable hemlock for this build, including 2x4s for the internal frame and 2x10s for the main wall panels. Hemlock weathers beautifully and is strong enough to handle outdoor conditions without additional treatment.
The boards are selected not just for durability but also for their character. Choosing the best-looking pieces for the front face adds curb appeal to your garden setup.
Preparing the Ground
Before construction begins, the planting site is cleared and roughly leveled. Removing sod helps define the shape of the bed and makes installation easier.
Sam outlines the bed using string and stakes, planning for dimensions of roughly 16 feet long by 4 feet wide. Some grass may remain, which is fine since it will decompose and enrich the soil below.
Framing the Bed
The bed is anchored with four upright corner posts to keep everything square and supported. These posts provide the structure that holds the weight of the soil in place.
Once the posts are positioned, 2×10 boards are laid along the sides and fastened into place. Using heavier-duty screws ensures the frame stays rigid over time.
Adding Strength and Style
To finish the bed, Sam installs 1×4 trim along the top and corners. This not only covers exposed screws but also improves the overall appearance of the structure.
The top trim includes a small overhang to create a comfortable edge. This small detail adds refinement and gives the garden bed a finished, intentional look.
Filling the Bed for Planting
With the frame complete, it’s time to fill it. Sam starts with a base layer of logs, sticks, and other organic matter to reduce the need for excess topsoil.
This method encourages long-term soil health as the lower materials break down and enrich the bed. The final layer is filled with a blend of topsoil and compost, ready for planting.
Wrapping Up the Project
The full build takes just over four hours and costs around $150. It’s a straightforward and satisfying project that creates an instant upgrade to your outdoor space.
Sam plans to share follow-up videos showing what gets planted and how the bed performs over time. It’s a great example of simple design done right.

Matt’s Take
These are my personal thoughts and tips based on my own experience in the shop. This section is not written, reviewed, or endorsed by the original creator of this project.
There’s something satisfying about a simple, well-built raised bed like this. Hemlock is a solid choice for outdoor projects — it’s naturally resistant to rot and develops a nice silver patina over time. At around $150 for materials, you’re getting good value compared to many pre-built options that can cost twice as much.
The layered filling approach Sam uses is smart. Starting with logs and organic matter at the bottom creates what’s called “hugelkultur” — basically composting in place. As those materials break down, they’ll retain moisture and slowly feed your plants. Just make sure any wood you use hasn’t been treated with chemicals.
One thing I appreciate about this design is keeping it simple with standard lumber dimensions. No complex joinery means fewer opportunities for mistakes, and the corner posts provide plenty of structural support for the soil load. When you’re dealing with that much weight pressing outward, having solid anchor points makes all the difference.
For anyone considering a similar build, remember that soil is heavy — roughly 100 pounds per cubic foot when wet. A bed this size will hold close to two tons when fully loaded, so don’t skimp on the fasteners or corner bracing.
