Most projects also involve professional, council, and site-related costs before construction starts. Some of these are calculated directly into your estimate below when ticked — others are flagged for follow-up.

Demolition & Asbestos

Any removal of existing materials or items is classed as demolition and is not included in this estimate.

Not included in this estimate — if present, this will need to be assessed and costed separately once more information is available.

Indicative Fees

Tick anything that applies to your project — these are added directly into the estimate below, using the figures shown.

2–6% of build cost
0.5–2% of build cost
$2,000–$8,000
$300–$2,000
$2,000–$10,000+
5–10% of build cost

May include architect and building designer fees; structural, civil, hydraulic, mechanical, and fire engineering; energy efficiency reports; surveying and soil tests; council and certifier fees; service connections; landscaping; and furniture, signage or loose equipment.

Requires a separate quotation.

Walls over 1m may need engineering design and certification — we'll confirm whether that applies and quote it separately.

Add each staircase separately — they don't need to be the same finish.
