Want to grow more vegetables, protect your crops, or extend your growing season without spending a fortune on a fully shipped greenhouse structure?
The Bootstrap Farmer DIY Gothic High Tunnel Greenhouse Kit offers an affordable way to build a spacious, professional-style growing environment using a combination of included specialty greenhouse components and locally purchased materials.
Designed with a distinctive gothic arch, this greenhouse provides extra interior headroom, taller sidewalls, and a steeper roof pitch compared with many traditional round hoop houses.
That means more room for trellised crops, better overhead clearance, and a roof shape designed to encourage snow and rain to slide off more efficiently.
Available in 14-foot and 20-foot widths, with multiple length options, this DIY greenhouse kit makes it possible to create a growing space tailored to your property and budget.
Not all greenhouses are shaped the same.
Traditional round hoop houses are popular because they're simple and effective, but their curved sidewalls can limit usable growing height near the edges.
A gothic greenhouse features a more pointed roof profile, creating additional vertical clearance and a steeper roof pitch.
Increased interior headroom
Taller usable growing space near the sidewalls
More room for trellising tomatoes, cucumbers, and other tall crops
Steeper roof pitch for improved rainwater runoff
Roof shape designed to encourage snow shedding
Spacious interior for gardening and farm operations
Important: The gothic design can improve snow shedding, but it does not eliminate the need for snow management or establish a specific snow-load rating.
One of the biggest expenses associated with larger greenhouse kits is shipping long steel tubing and lumber.
Bootstrap Farmer designed this DIY Gothic High Tunnel Kit to help reduce those costs.
Instead of shipping every piece of framing material, the kit provides specialty greenhouse components while allowing you to purchase common materials locally.
1⅜-inch steel top rail for the greenhouse frame
Lumber for the required structural and end-wall components
This approach can reduce shipping expenses and give you more flexibility when sourcing materials.
The manufacturer provides a printable purchasing guide to help you identify the materials required for your selected greenhouse size.
Please note: The greenhouse cannot be assembled from the shipped kit alone. Additional locally sourced materials are required.
Choose from two widths and five standard lengths.
Available lengths: 20', 40', 60', 80', and 100'
Approximate overall height: 12.5–13.5 feet
Suitable for homesteads, market gardens, and smaller growing operations
Available lengths: 20', 40', 60', 80', and 100'
Approximate overall height: 15.5–16.5 feet
Provides additional growing width and overhead clearance
Heights are measured from the ground with the ground posts installed and may vary based on construction details.
| Greenhouse Size | Approximate Ground Area |
|---|---|
| 14' x 20' | 280 sq. ft. |
| 14' x 40' | 560 sq. ft. |
| 14' x 60' | 840 sq. ft. |
| 14' x 80' | 1,120 sq. ft. |

| 20' x 40' | 800 sq. ft. |
| 20' x 60' | 1,200 sq. ft. |
| 20' x 80' | 1,600 sq. ft. |
| 20' x 100' | 2,000 sq. ft. |
These figures represent nominal ground footprints. Actual planting area depends on bed layout, walkways, and equipment placement.
The additional headroom of a gothic greenhouse can be especially valuable when growing crops that need vertical space.
Consider using your greenhouse for:
Trellised tomatoes
Cucumbers
Peppers
Cut flowers
Specialty vegetables
Seedling production
Market garden crops
Season-extension growing
The taller design can also provide additional room for compatible irrigation, trellising, and ventilation systems.
The kit includes 6-mil greenhouse plastic with a manufacturer-listed four-year rating.
The supplied film is sized to cover the greenhouse structure, including the end walls.
The kit also includes spring lock wire and lock channel to help secure the covering.
The included lock channel quantity assumes a single-door end-wall arrangement. Additional channel may be necessary if you plan to install double doors, windows, or other custom openings.
Note: The greenhouse plastic may arrive separately and could require additional shipping time for certain freight shipments.
