Assumptions & limits+
- Money figures use MAYA's illustrative planning rates — an indicative estimate, not a quotation. A site-verified BOQ follows a consultation.
- Items are included only when a quantity is entered; zero-quantity items are excluded.
- Materials : labour planning ratio is 65 : 35 for carpentry-led interiors.
- Turnkey mode includes design fee, execution items and project management.
- GST (18%) is included in the planning total.
What does the materials : labour split mean?+
A planning ratio (65 : 35) typical for carpentry-led interiors. Actual proportions depend on the finish; a quotation itemises both.
Are appliances and counter stone included in the kitchen rate?+
No — the kitchen rate covers base and wall units with standard hardware. Appliances, sink, tap and counter stone are separate.
Can I get a room-wise estimate?+
Run the calculator once per room and note each result; a consultation produces a consolidated room-wise BOQ.
