A real block in Sydney: 8 Wyralla Avenue, Epping
The lot is 593.1 m² in the Low Density Residential zone. What the design engine drew on it:
- Knock-down rebuild: 1 home, 1 storey, 4 bedrooms, about 225 m² each
- Side-by-side pair: 2 homes, 2 storeys, 3 bedrooms, about 185 m² each
- Two-storey row: 3 homes, 2 storeys, 3 bedrooms, about 174 m² each
What it left out, and why:
- Single-storey row of 3: Every row home must be at least 20 m deep (house size range), but the rear setback on lot 1 (CDC-3B.36 3 m) leaves room for 17.4 m.
- Four-home row: A row of 4 needs at least 24.55 m of street frontage: lots of 6.78 m, 5.5 m, 5.5 m, 6.78 m. Each end lot needs a home as wide as the one between (5.5 m) plus the upper floor's side setback (CDC-3B.11 1.28 m). That is the narrowest townhouse with a single garage (5.5 m). This block has 22.89 m of street frontage.
