How to Build a Venetian Style Garden Screen
A Venetian garden screen uses horizontal timber battens fixed to a vertical frame at even intervals, creating a layered louvred effect. It is one of the most achievable garden projects for a competent DIYer. Use 25×50mm (2×1) rounded edge landscaping batten for the horizontal slats. Use our Landscaping Batten Calculator to get the exact quantity for your screen before you order.
The Venetian garden screen is the project that keeps coming up in garden design conversations. Clean horizontal lines, a contemporary feel, and a result that looks custom and expensive even when it is not. You have probably seen it used as a seating area backdrop, a hot tub screen, or a boundary fence that manages to feel like a garden feature rather than just a barrier.
The good news is that it is not a complicated build. If you can set posts in the ground, fix timber rails between them, and work to a consistent spacing, you can build a Venetian screen that looks as good as anything a landscaper would install.
What makes it Venetian?
The name comes from the Venetian blind — the layered horizontal slat effect that gives privacy while still allowing light and air through. Where a standard fence has battens running vertically, a Venetian screen has the battens running horizontally between posts at each end of the bay.

How to build it — step by step
Plan the screen
Decide on the total width, height and number of bays. Sketch the layout on paper before anything goes in the ground. A standard 1.8m bay needs a post at each end. If your screen is 3.6m wide, you need three posts.
Set your posts
Dig post holes to the correct depth. For a 1.8m screen, use a 2.4m post with 600mm buried. Mix Postcrete as directed and check plumb with a spirit level before it sets. Leave overnight before continuing.
Add a top and bottom rail
Once posts are solid, fix a horizontal rail across the top and bottom of each bay. These rails add rigidity and give you fixed points to work from. Use a string line or laser level to keep rails level across multiple bays.
Fix the battens
Starting from the bottom, fix your first landscaping batten horizontally between the posts using two screws at each end. Cut a spacer block to your chosen gap width — typically 25–40mm. Place the spacer on top of the first batten, sit the next batten on it, and fix. Work your way up the frame.
- Check level every three or four battens
- Keep the spacer block the same width all the way up
- Pre-drill near ends to prevent splitting
- Two fixings per end per batten — do not skip
Trim and finish
Trim any battens that overhang the posts if a flush finish is required. Treat any cut ends with an end grain preservative. Cap post tops with post caps. Leave natural, paint or stain — all work well on pressure treated landscaping batten.
Cut one spacer block to your exact gap width and use it for the entire screen. It takes one minute and gives you perfect, consistent spacing from bottom to top — far more reliable than measuring each gap individually.
How many battens do you need?
Rather than calculate by hand, use the calculator. Input your screen height and width, choose your batten size and spacing, and it returns the exact quantity to order.
However accurate your measurement, always add a few lengths to your order as a contingency. Running out mid-build and waiting for a second delivery is more frustrating than having a couple of lengths left over.
Frequently asked questions
What size batten is best for a Venetian screen?
25×50mm (2×1) rounded edge landscaping batten is the most popular choice. It gives a clean, modern profile that suits most garden styles.
How far apart should the battens be?
For privacy, 20–30mm gaps are standard. For a more open, airy feel, 40–50mm works well. Think about the ratio of batten width to gap as much as the absolute measurement.
Should I angle horizontal battens?
A very slight downward angle toward the front face of the screen helps shed water and prevents pooling on top of horizontal battens.
