Yes

Indicatively 2 lots

01 · Answers

A no is an answer. So is “we can’t assess this”.

Every answer is set the same way, in the same place, with the same care. Four real NSW addresses, checked against live government data.

  1. WEST AVENUE 1 1 1 2 2 19.5 61.5 19.4 61.5 Lot 11,198.3 m²
    LOT 1 DP199700N020 m

    Yes

    Indicatively 2 lots

    178 West Avenue, Glen Innes NSW 2370

    The area comfortably clears the minimum for 2 lots. It is 151.7 m² short of a third.

    1,198.3 m² ÷ 450 m² = 2.7 → 2 lots

  2. WATTLE STREET 1 C A B 1 24.8 47.0 23.9 Lot 2628.3 m²
    LOT 2 DP520571N020 m

    No

    Stays as 1 lot

    22 Wattle Street, Peakhurst NSW 2210

    At 628.3 m² it does not reach 2 × 450 m² (= 900 m²), so it stays as one lot.

    628.3 m² ÷ 450 m² = 1.4 → 1 lot

  3. DRIVER AVENUE 6 11 10 9 8 7 5 3 18 69.6 85.1 72.3 89.2 SP305147,483.0 m²
    SP30514 · STRATA PLANN050 m

    Can’t assess

    Strata lot, so no lot count

    2 Park Road, Wallacia NSW 2745

    NSW Cadastre lists this as a strata lot. Strata follows a different pathway, so we don’t guess a number.

    Strata lot SP30514: the Torrens area test does not apply

  4. No lot to draw
    NO LOT MATCHED

    Not found

    No lot matched this address

    9 Marine Parade, Manly NSW

    We couldn’t locate that address. Try the street number, street and suburb, or check the spelling.

    No lot matched, so nothing is guessed

02 · The working

Every answer shows its arithmetic.

Lot area, divided by the minimum lot size the council maps for that spot, rounded down. Each number names where it came from.

1,198.3 m²Lot areaMeasured from the lot’s boundary in the NSW cadastre (Lot 1 DP199700), not taken from a listing.
450 m²Minimum lot sizeThe Lot Size Map of the Glen Innes Severn LEP 2012, for zone R1 at this lot.
2.7Lots by area3 lots would need 1,350 m². This block is 151.7 m² short.
2 lotsRounded downA part of a lot is not a lot. A dwelling is not a lot either.

Rules-based, not AI-generated

The same address gives the same answer, from published NSW rules as at 30 September 2026. Nothing is estimated by a language model, and when a rule cannot be applied, SplitCheck says so instead of guessing.
