DIY Raised Garden Bed With Privacy Wall

As you can tell by the name of the project, I built this to have both a tall, raised garden bed and fence to add privacy in my back garden.

The plan is simple: build a raised bed with 4×4 posts and make the two back posts tall enough to support horizontal fence boards, essentially forming a privacy wall.

After building the original box, I liked the privacy aspect so much, I added “wings” on either side for extra privacy. I staggered their placement to keep it stable and add interest.

I’m an amateur woodworker and often build things without following plans, just figuring it out as I go. But, so many of you have written to request details since I originally shared this so I have drawn up some plans.

My actual raised bed has a footprint of 8×4-feet. Many of you have asked for 6×3 specs so I have included material lists for both sizes.

If you are new to raised beds, see Free Raised Bed Building Plans for tips to know before you build.

2Materials

Lumber Notes

I used pressure-treated wood that comes in a ‘sienna’ brown color.

To avoid wasting wood, I try to create my designs working with standard lumber sizes so there are as few waste cuts as possible. For this project it means creating a box to match your fence board lengths.

For example, my unit is 8-feet wide so the privacy fence is 8-feet wide as well.

• Be sure to measure your boards before you start to make sure they are the right or same lengths. It’s expected that actual lumber sizes are different than the common names we use for them (e.g. a ‘2×4’ is actually 1.5 x 3.5), but the lengths can vary too, even in the same lot.
  
  The plan does include corner covers to conceal the fence board ends so that will hide any slight variances around the box.

Option 1

6x3x2 raised bed with 6-foot privacy wall

Lumber

1×6 Fence boards

• (7) 1x6x72 (privacy wall boards)
• (6) 1x6x21.75 (corner covers)
• (2) 1x6x18.25 (short back corner corners)

2×8 Fence boards

• (6) 2x8x72 (long box sides)
• (6) 2x8x36 (short box sides)
• (2) 2x8x83.5 (long miter tops) – approx.
• (2) 2x8x44 (short miter tops) – approx.

2x4s

• (1) 2x4x72 (back horizontal support)
• (2) 2x4x21.75 (vertical box supports)
• (1) 2x4x36.75 (optional vertical back support for privacy wall)

4×4 posts

• (2) 4x4x72 (back corner posts)
• (2) 4x4x21.75 (front corner posts)
  The length of these posts should equal (3) fence board widths. Our fence boards are 7.25-inches wide x 3 = 21.75.

Tools and Hardware

• #8 Deck screws (various lengths)
  I used approximately (132) 2.5” #8 deck screws and (56) 1.5” #8 deck screws
• Miter saw
• Cordless drill and bits
  For #8 screws use 7/64″ bit for pilot holes and a 3/8″ countersink bit to sink the screws.
• Long level or laser level
• Pencil
• Safety glasses, gloves, and ear protectors
• Landscape fabric (optional) – to line the box
• Staple tool (optional) – to attach landscape fabric

3Prepare Your Location

Before You Build

Prepare the location where you will be placing the box. You will need at least 6×3-feet or 8×4-feet of level ground, depending on which size box you build.

You will also need enough soil to fill the box. I had recently built a pond and used some of the soil from the excavation for all but the top 12-inches which I amended with compost.

You can find more budget-friendly fill ideas here: How To Fill A Tall Raised Bed & Save On Soil.

This cardboard sheet mulch method is good for suppressing any grass or weeds in the base area.

4Assembly

As you work, consider where you will attach screws both for maximum hold and best appearance. For some of the boards, you can attach the screws from inside the box to conceal them.

The difference between a good build and a bad one is how square and level it is! Check your work as you go. It will look professionally-built if you do this.

Assemble the Front and Back Sections

The footprint of the raised bed is 6-feet by 3-feet (for Option 1).

The two tall 4×4 posts go at the back corners and the two short 4×4 posts go at the front.

The posts will be inset 1.5-inches (the width of a 2×8) to allow room for the fence boards to neatly butt up against each other.

Work from the bottom up by lining up the bottom of the first board with the bottom of each post. Add the remaining two boards.

Remember where you’ve placed your screws so you don’t run into them when attaching the corner covers.

Repeat for back section using the tall 4x4s. 

The front and back box sections also have vertical 2x4s at their middle points to further support the horizontal boards.

Mark the middle of each unit and attach the 2x4s from the inside so the screws are not visible on the outer fence boards.

Join the Front and Back Section By Attaching the Side Boards

With the front and back sections assembled, it’s time to assemble the box by attaching the shorter horizontal boards on each side.

Add the side boards, starting from the bottom up, attaching them precisely between the front and back sections. They will fit nicely behind the overhang of the long front and back boards.

Complete both sides.

Now you have the basic box.

Attach Back Support Board (for Mitered Top)

Attach a 2×4 across top back of box. The top edge of the board should line up with the top edge of the top horizontal board. The purpose of this board is to add extra support for the mitered top we’ll add later.

Attach Corner Covers

Attach the front corner covers first, placing the front boards 5/8 beyond the edges of the front section.

Add side covers, butting each one up behind the front cover overhangs.

For back corners, use the shorter pieces (18.25-inches) at the back, attaching each one right below the 2×4 support piece with their edges aligned with the corners.

Finish by adding the final two corner pieces (21.75-inches) at back of sides, extending 5/8-inch beyond the box to end flush with the back corner pieces.

Attach Mitered Tops

Plan your mitered boards so they conceal the perimeter of the top of the box on all sides including the front 2×4 posts.

The measurements I’ve provided are approximate.

If you don’t want to miter them, butted square ends are fine too.

Optional

I lined my raised bed with heavy duty landscape fabric because I had some on hand. It may help extend the life of the box—I hope. If you want to do this, staple it in place before adding the mitered tops.

Attach Privacy Boards

Use a spare 2x4x6 (or 8) to secure the back posts in position so you can add the privacy boards without worrying about movement.

Starting at the top of the tall posts, attach your fence boards. Line up the top edge of the top board with the top edges of the posts and be sure they extend (overhang) equal distances from the post edges. Double check the boards are level before securing them.

Attach remaining boards, working your way down. Leave a slight gap to allow for board expansion from humidity.

Optional

You may also want to add a 2×4 along the middle, back of the privacy wall to prevent warping.

5Extend the Privacy Wall

These next photos show the evolution of my privacy wall.

The “wings” are staggered which provides better stability and a less boxy appearance.

The wing boards are attached to the back of the main box posts but in front of their own posts.

I also varied the heights and widths to add more interest.

For some of the post supports (next picture) I made cylinders of hardware cloth, tied shut with cable ties, and filled with stones.

Here is the final project:

6Alternate Design

I cannot tell you how fun it is when someone emails me to share photos of a project inspired by something I have shown on this site.

Helen Prier did a beautiful job on her version of these raised beds with privacy walls. It’s a huge undertaking, but so worthwhile if you have a yard lacking character and privacy.

And it is a fabulous way to workaround any fence height restrictions simply by building a little higher within your own property.

A few details to note:

• The boards are cedar and everything was stained prior to assembly.
• The raised bed boards are reclaimed cedar which Helen stained black to hide any discolorations.
• The main raised beds are 3 (2×6) boards tall for a height of 24-inches. These boxes are finished with stained cedar tops to match the walls.
• The smaller raised beds between them are 2 boards tall.

Here are a few photos Helen shared of the building process.

Before

This first photo shows a common situation: a good size garden space but no real definition to the space.

During Construction

The taller raised beds were built first, complete with the tall 4×4 support posts.

Adding Privacy Boards

Notice how the horizontal privacy boards are placed? They alternate between the front and back side of the 4×4 posts. It’s a good way to break up the effect so it looks more interesting than a solid wall of wood the whole way across.

Ready For Planting

You can see it was big job but wow, it looks great. The alternating wall placements, different stain colors, and varying box sizes really transform it into something special.

And what a fabulous place to get really creative with art and plants.

Thank you, Helen for sharing your wonderful project. Well done!
