Our brand-new DIY greenhouse kit is designed for growers who want the snow-shedding benefits, taller sidewalls, and interior headroom of a gothic arch greenhouse. With extra clearance for trellising, airflow, and tall crops, this DIY Gothic high tunnel makes it easy to extend your season and grow more.
These gothic greenhouse kits are designed to save you money on shipping by requiring the purchase of metal and lumber locally. We’ve provided information below from Lowe’s and Home Depot with part numbers and their respective prices* (as of 2025) to help you source what you need.
Check out this quick start guide video for an overview of the build.

Greenhouse Kit Includes:
DIY gothic preformed peaks
Spring lock wire and lock channel to keep your greenhouse plastic secure (assumes a single door on your high tunnel). Additional channel may be necessary for a double door or windows.
1 3/8" x 1 3/8" cross connectors to attach arches to ridge poles and to purlins
Greenhouse Plastic 4 Year 6 mil. Sized to cover the entire greenhouse, including end walls. (It may take an additional week to arrive if freight shipment is required.)
All required screws, nuts, bolts, and connectors for pole and frame components
Lumber and 1 3/8" Top Rail is not included. We want to save you money. Buying this locally will save you thousands, which is why we don't include it. We want you to build a high-quality greenhouse at the most affordable price. See our "Purchase Locally" below for help ordering all the lumber and top rail.
* Lumber choices may be limited by location. Redwood, cedar, or pressure-treated are the best choices for any structure that will be exposed to moisture.
