Under the floor

Soil

Reactive clay

Moderately to highly reactive clay (Class M to H). Seasonal movement causes hairline cracking in brickwork and render. Modern slabs are engineered for it; older strip footings were not. Consistent moisture around the house is the whole game.

In the walls

  • Asbestos eaves, wet-area lining and fences
  • Galvanised water pipes
  • No insulation in walls
  • Two-wire lighting circuits
  • Concrete-panel Commission homes need specialist assessment before major changes
  • Asbestos still present in wet areas and eaves to the mid-80s
  • Single-glazed dark aluminium windows
  • Original ducted systems at end of life

Questions about Smithfield

Do houses in Smithfield have asbestos?+

Likely in the older stock. About 60% of Smithfield was built between the 1920s and 1980s, the peak asbestos period. Eaves, wet-area sheeting, fences and sheds are the usual places. Test before you drill, sand or demolish.

What soil is under Smithfield?+

Reactive clay. Moderately to highly reactive clay (Class M to H). Seasonal movement causes hairline cracking in brickwork and render. Modern slabs are engineered for it; older strip footings were not. Consistent moisture around the house is the whole game.

Can I subdivide a block in Smithfield?+

High subdivision pressure: Two or three homes replacing one on many streets. Original houses are becoming the minority and land value drives everything. Typical blocks are 600-800m² originals, 300-450m² new. Check the zone and minimum site area in the Planning and Design Code for the exact street.
