Build a Taller Greenhouse With a Snow-Shedding Gothic Design
The DIY Gothic Greenhouse Kit is designed for growers who want the snow-shedding benefits, taller sidewalls, and extra interior headroom of a Gothic arch greenhouse. The steep roofline provides additional clearance for trellising, airflow, and tall crops while helping snow and water shed from the greenhouse covering.
Available in 14′ or 20′ widths and lengths from 20′ to 100′, this DIY high tunnel gives you plenty of flexibility to choose a growing space that fits your property. The 14′-wide greenhouse stands approximately 12.5′–13.5′ tall, while the 20′-wide greenhouse reaches approximately 15.5′–16.5′ tall.
To keep the kit affordable to ship, the bulky metal tubing and lumber are purchased locally. Your greenhouse kit includes the specialty greenhouse components, covering, hardware, connectors, and preformed Gothic peaks needed to complete the structure with your locally sourced materials.
This greenhouse kit is not eligible for returns.

The included lock channel assumes a single-door configuration. Additional lock channel may be needed if you plan to build double doors or add windows.
Lumber and metal tubing are not included and must be purchased locally.
Locally Sourced Metal & Lumber
The DIY Gothic Greenhouse is designed so the bulky metal tubing and lumber can be purchased near you rather than shipped with the kit. This helps reduce the cost of getting a large greenhouse structure to your property.
The exact materials required depend on the width and length you select.

| 14′ × 40′ | 560 sq. ft. |
| 14′ × 60′ | 840 sq. ft. |

More Headroom for Tall Crops & Trellising
The Gothic profile provides substantially more vertical space than a traditional rounded hoop design.
The 14′-wide greenhouse reaches approximately 12.5′–13.5′ tall, while the 20′-wide greenhouse reaches approximately 15.5′–16.5′ tall. That extra clearance gives you more room for trellising tall crops while providing additional interior headroom and airflow.
Designed to Shed Snow & Water
The steep Gothic arch is more than a distinctive shape. Its pitch is designed to shed snow better than a round hoop greenhouse while also improving water runoff from the greenhouse covering.
That makes the Gothic design particularly well suited to growers in snow-prone climates who also want the growing advantages of a tall high tunnel.
Customize Your Ventilation & Access
The included lock channel is based on a single-door greenhouse configuration. Additional lock channel may be needed if you choose to build double doors or add windows.
Preparing for Your Build
Because this greenhouse combines the supplied kit components with metal and lumber purchased locally, review the materials list for your selected width and length before beginning your project.
Make sure your locally sourced materials are available and ready before starting assembly. Lumber availability can vary by location, particularly when choosing moisture-resistant options such as redwood, cedar, or pressure-treated lumber.
Review the complete assembly instructions and Buy Local Chart before beginning construction so you know what you'll need for your specific greenhouse size.

This greenhouse is designed for DIY assembly on site using the components supplied with the kit along with your locally purchased metal tubing and lumber.
