Under the floor

Soil

Bay of Biscay reactive clay

Highly reactive black or grey clay that swells in winter and shrinks hard in summer. Cracked walls, doors that stick in one season and swing in another, and slabs designed to Class H1 or H2 (deep edge beams or waffle pods). Keep water away from the footings and do not plant big trees close to the house.

In the walls

  • Asbestos in eaves, bathroom, laundry and fence
  • Galvanised pipes and low water pressure
  • Empty wall cavities (no insulation)
  • Original switchboard with ceramic fuses
  • Stumps due (VIC) or slab-edge dampness (SA)
  • Party walls and shared driveways on community or strata titles
  • Small setbacks mean little garden and less solar access
  • Quality varies enormously between developer-builders
What each of these costs to fix

How the streets are changing

Following Campbelltown into two-for-one subdivision, a few years behind.

The thing locals know

Many 1960s homes here were owner-built by Italian families with cellars and double-brick internal walls. Demolition costs more than the quote assumes.

Can I subdivide a block in Newton?+

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 650-850m². Check the zone and minimum site area in the Planning and Design Code for the exact street.
