Work out polyhouse cost instantly with clear inputs, formula shown and shareable results.
Polyhouse capital cost is area x rate per square metre, which varies with structure type — bamboo and wooden houses are cheapest, galvanised iron naturally ventilated houses mid-range and fan-and-pad climate-controlled houses several times more. Netting off subsidy and spreading the balance over the structure life gives the annual capital charge the crop must cover.
Polyhouse cost
Gross = area x cost per m2; net = gross x (1 - subsidy %); annualised = net / life in years
Subsidy rates, ceilings and eligibility vary by scheme, state and category of beneficiary. Confirm current terms with the horticulture department before committing.
Structure, cladding film, doors and basic ventilation. Irrigation, fertigation, shade nets, insect screens and a water source are usually extra and can add 20-40%.
UV-stabilised polythene lasts 3-5 years depending on grade and sunlight. Budget a recurring cost for recladding separately from the structure life.
