A wall you can't hear through
The party wall uses a double-stud, acoustically decoupled system tested to block conversation-level noise between dwellings.

The Brief
How this home came to be.
Duplex living succeeds or fails on the details neighbours never see — how sound moves through a party wall, whether two families can host on the same Saturday without hearing each other's dinner conversation. We designed both dwellings as mirror images with an acoustic-rated party wall and separated services from the footings up.
Inside, sheer curtains and a considered furniture layout soften what is, structurally, a very efficient plan — proof that a duplex doesn't have to look or feel like one.

Photographs
On site.
Shot over three visits — dawn, midday and dusk — so the material palette reads the way the family will actually live in it.
What's inside
The specification, in plain English.
Every line here is something we insisted on — not something added to fatten a quote.
- 01Mirror-image floor plans sharing one acoustic party wall
- 02Fully independent services — no shared meters or stormwater
- 03Private, screened courtyard to each dwelling
- 04Sheer curtain tracks concealed in a plaster bulkhead
- 05Engineered European oak flooring throughout living areas
- 06Separate driveway crossovers to avoid shared access disputes
Signature moments
The things worth
pointing out.
Small decisions that only reveal themselves once you're living in the house. These are ours for this project.
Matched, not identical
Each dwelling mirrors the other's plan exactly, but joinery tones were varied slightly so neither owner feels they got the 'other' house.
Gardens that don't overlook
Courtyard fencing and planting were set out specifically so neither dwelling's outdoor space looks into the other's.
Where it stands
Yarralumla,
Inner South.
