Free greenhouse tools
Every other greenhouse calculator online is run by someone selling you a greenhouse, so the number always points at a bigger purchase. These don't. We don't sell greenhouses. Get the real number first, then decide.
Premium Greenhouse Project Brief
Price the whole premium project before you ask for quotes. See missing budget lines, who usually owns each piece of work, which brands are genuinely comparable, and what must be in writing before you pay a deposit.
Open the tool →Greenhouse Size and Cost Calculator
Set how you will garden, your climate, and the project scope. Get a size and glazing recommendation plus a cost range that shows exactly which structure, base, ventilation, heating, site work, assembly, utility, and permit lines are included. The kit price is not the project price.
