Petersham, in Sydney’s Inner West, is full of Federation-era homes and narrow backyard footprints. When your entire outdoor space is a tight strip between the house and the boundary, every millimetre matters — and a deck-and-fence combination is one of the most effective ways to make that space feel intentional rather than leftover.
This Petersham project is a real example: a full merbau deck and matching fence installed in a narrow, tight backyard where access, alignment and boundary clearances all had to be exactly right.
The Challenge: A Tight Space Where Nothing Can Be Approximate
Narrow backyards punish guesswork. With a working width of just over a metre and a half in places, there was no margin for “she’ll be right” measuring. Every board had to be:
- Cut to the actual boundary line, not the plan’s assumed line, because heritage boundaries are rarely square
- Aligned with the new fence, so the deck edge and the fence base read as one continuous detail
- Graded correctly, so water sheds away from the house in a space where pooling would otherwise sit against the structure
The difference between a good result and a great one in a tight space is patience — measuring twice, dry-laying boards before fixing, and adjusting the framing until the lines are genuinely parallel. That’s exactly the approach we took here.
Why Merbau Works for Deck-and-Fence Combos
We used merbau (kwila) for both the deck and the fence for three reasons:
- One species, one colour story. Deck and fence built from the same merbau batch age to the same warm honey-brown, so the two elements read as a single designed feature rather than two separate structures.
- Class 2 durability above ground. Merbau’s density (around 850 kg/m³) and natural oily composition resist rot, insect attack and the sort of surface wear a boundary fence copes with year after year.
- It machines cleanly. In a narrow site, the fence and deck framing interact — posts, rails and joists share space with meter boxes, downpipes and AC lines. Merbau cuts and takes fixings without splitting, which makes tight-site carpentry far more precise.
If you’re weighing merbau against other premium hardwoods, our Spotted Gum vs Merbau comparison for Sydney coastal properties breaks down durability, movement and cost differences.
The Build: Precision You Can See in the Result
On this job, the sequencing mattered. The fence went in first, so the deck framing could be set off the exact fence line rather than a paper measurement. From there:
- Framing was levelled with packers against a subtle fall toward the yard’s drainage point
- Merbau boards were dry-laid across the full length before a single screw went in
- The final deck edge was scribed to the fence base, leaving a clean 5mm shadow line that hides seasonal movement without collecting debris
- Both deck and fence were finished with penetrating hardwood oil to lock in colour and even out grain variation
The result: the deck and fence line up so cleanly that the backyard reads as a designed room, not a corridor.
What the Homeowner Said
“It’s quite a narrow and tight space, so it seemed like a challenging area to install a deck. During the installation, you could really see the care taken to get all the measurements right. Everything fits perfectly, and the deck and fence are beautifully aligned with the backyard. We absolutely love the result.”
That’s the standard we hold ourselves to on every narrow-site build — and it’s why we photograph and document our Inner West projects properly. You can see the full deck, screening and feature gate treatment on our earlier Petersham heritage terrace project write-up.
Planning a Deck and Fence in a Narrow Backyard? Three Tips
1. Fence first, deck second
Building the fence line first gives your deck a true reference edge. Retrofitting a fence to an existing deck almost always leaves a compromise gap or an awkward trim line.
2. Insist on a site-specific drawing
Any builder can quote a narrow backyard over the phone. Ask for a scaled plan showing boundary clearances, service points and fall direction before work starts — it’s the single best predictor of a clean result.
3. Keep the materials consistent
Mixed species in a small space exaggerate colour differences. One timber for deck, fence and any screening keeps a tight space calm and cohesive.
