Inter-war Cottage Restoration
Sydney's 1920s–1940s cottages and California bungalows are everywhere — and most need work after a century of weather and renovation cycles.
Inter-war housing — the cottages, California bungalows, Spanish Mission homes and Tudor Revivals built between the wars — fills entire suburbs across Sydney. Burwood, Concord, Strathfield, Haberfield, Mosman, Lane Cove, Vaucluse and Bellevue Hill all have streets of them. They're typically face brick, sometimes with decorative render or tiles, on substantial timber-framed roofs.
These homes are now 80–100+ years old. Most have been altered, extended, repainted or partially renovated multiple times. Some have been beautifully maintained; many have had bad work done in the 1960s–80s that needs unpicking. Our job on inter-war homes is usually a mix of repair, careful removal of bad alterations, and bringing materials back to where they should be.
The good news: inter-war construction was generally solid. Solid double-brick walls, decent footings, good timber. When the issues are addressed properly, these homes have plenty of life left.
Defining characteristics
What makes inter-war cottage buildings recognisable, and what each detail means for restoration:
- Solid double-brick or brick-veneer construction
- Face brick exteriors, often with decorative banding or quoining in contrast brick
- Decorative render panels — Spanish Mission stucco, Tudor half-timbering, California bungalow porch detailing
- Tile roofs (terracotta or concrete) with deep eaves
- Decorative timber porch and verandah structures
- Sandstone or concrete plinths and steps
- Early Portland cement mortars — harder than Victorian-era lime but softer than modern
What we see most often
The issues that come up across most inter-war cottage buildings we assess.
Painted brick faces
Many inter-war homes had their original face brick painted at some point — usually a 1970s–80s "modernisation". Stripping paint to expose original brick is a major undertaking but the result is dramatic. Done carefully with chemical strippers (not abrasive blasting), the original brick recovers well.
Cracked render panels
Decorative render — especially Spanish Mission stucco and California bungalow porch detailing — cracks over decades. Where the cracking is just surface, we patch and re-finish. Where the render has detached from the substrate, full section replacement is needed.
Failed mortar joints
Inter-war mortars were transitioning from lime-rich to harder Portland cement-rich mixes. Many of these mortars have failed at the joint faces, leaving open joints that let water deep into the wall. Repointing with a matched mortar — softer than modern cement, harder than Victorian lime — is the right approach.
Rusted lintels
Inter-war steel lintels above doors and windows commonly rust and push the brickwork apart. Replacement with new structurally-rated steel, properly corrosion-protected, plus repair of the surrounding brickwork.
Foundation settlement
Inter-war footings were generally shallow concrete or sandstone. On reactive clay soils (common across the Inner West and Greater Sydney suburbs) seasonal movement is normal. Most cracking is cosmetic but should be checked. Where active movement is happening, targeted underpinning may be needed.
How we approach this work
- 01Mortar mix design specific to the building age — not too soft, not too hard
- 02Salvaged or matched face brick for any replacements
- 03Chemical paint stripping where exposing original brick is the goal — never abrasive blasting on inter-war brickwork
- 04Render finish matching with test panels — Spanish Mission texture is particularly hard to fake
- 05Honest assessment of which alterations are worth keeping and which should be reversed
Common questions
Can you strip paint off our inter-war brick exterior?
Yes. We use specialist chemical paint strippers designed for masonry, not abrasive blasting which damages the brick face. It's slow work — several applications usually needed — and we always do test panels first to confirm the brick underneath is in good condition. The result transforms the look of the home.
Our California bungalow has cracked render around the porch. What's the fix?
Depends on whether the render has just cracked or has detached. Crack-only damage is patched and re-finished. Detached render needs cutting out, substrate repair, and full re-render with matched texture. We sample existing render to match colour and aggregate.
How do you match decorative brick banding?
Salvage yards stock a lot of inter-war brick. We source matched bricks for the contrast banding and quoining. Where exact matches aren't available, we make do with the closest match and accept that any new work will be visible up close.
What's the cost range for inter-war cottage restoration?
External facade restoration typically runs $20k–$80k on a single-storey cottage, depending on scope. Adding paint stripping and full re-pointing pushes it higher. Two-storey or larger homes scale accordingly. We give itemised quotes after walking the property.
