Site it on your actual land, then get the numbers that decide whether it works: what it costs to heat through a winter, what the water and power runs cost to put in, and the questions you need to take to your building department.
Plan for free. Pay once, when you want the finished blueprint. The planner works in English and Spanish.
Everyone planning a greenhouse is already doing one of these. Here's what each one actually costs you.
Draws the boxes. Doesn't know your setbacks, won't total your pipe, can't tell you what it costs to heat in January.
And when you move one greenhouse two feet, you redraw the whole sheet — so most people don't, and the plan stops being true.
Weeks of back and forth for a set of drawings. Worth it on a large commercial build, hard to justify on a first one.
And you pay again for the next property, and again every time you change your mind.
Drag the buildings around and the numbers follow — setbacks, pipe and wire runs, materials, and the heating bill for your climate and your fuel.
Change your mind as often as you like. Use it on every property you ever build on.
It doesn't replace your electrician or your engineer. It gives you real numbers to take to them, which makes that conversation shorter and cheaper.
For a first serious build. You don't need experience — you need to know what the structure costs to put up, what it costs to run through a winter, and which questions your county will ask. That's the part that catches people, and it's expensive to learn the other way.
Set the boundary, then drag greenhouses around it. Setbacks, slope and access update as you move things.
Benches, irrigation, lighting and heat. Capacity and power draw populate live as you build.
A phased budget, a plot plan your zoning officer will accept, and a build order you can hand to a contractor.
Plenty of tools will draw you a pretty greenhouse. The quote covers the structure. These four decide whether building it leaves you better off, and they're the ones a first-timer doesn't know to ask about.
More greenhouse plants die from heat than from cold, and the day that kills them is usually mild. GrowBlueprint works out how far above outside your house runs, and tells you which spring afternoon crosses the line while you're at work.
Ten US regions, design temperatures, seven glazing types with published U-values, and four fuels. The number that turns a good idea into a bad one.
Codes differ by state, county and city. GrowBlueprint prints the exact list to take to your building department — and never tells you you're exempt.
Every step checks for common planning mistakes documented in extension guidance and greenhouse build research — drainage, orientation, access, ventilation, snow load. Real ones, not filler.
Your complete pre-construction plan. Preview everything for free, pay when you're ready to download.
No account needed to start planning. Pay when you want the file.
14-day full refund if it doesn't do what this page says — the terms say so in writing.
No. You type in numbers about your property and greenhouses, and the tool does the layout and the maths for you.
No — it gives you real planning numbers to bring to them, which saves time and money on that conversation.
Published agricultural extension research, cited in the tool itself, so you can check any figure before you spend against it.
No, deliberately. Those are set by building codes that get revised on a cycle, and by your specific site. It prints the questions to ask your building department instead.
Tomatoes, cucumbers, peppers, leafy greens, herbs, strawberries, cut flowers and nursery stock — anything where the building is a real investment and the running cost decides whether it works. It is a building planner, not a growing course: it sizes the structure, the water, the power and the heat, and does not tell you how to grow anything.
It handles a 6×8 kit as happily as a commercial range, including tiered shelving.
Reopen the file any time and adjust your numbers — it remembers your last inputs.
The engineering is general: heat loss, structure, water and power sizing work the same everywhere. Anything that is local — permits, setbacks, licensing — it hands back to you as a question, never an answer.
Draw the property, drop the buildings on it, and watch the running cost appear. If the answer is that it doesn't work where you live, better to see that now than in January.
