Sturdi-Built Greenhouse Manufacturing Co. has been building high-quality redwood and glass greenhouse kits for over 50 years.

We make beautiful, high-quality greenhouse kits in our factory in Portland, Oregon, using the finest redwood available – Clear All Heart Redwood – and American made glass. Excellent materials make our greenhouses naturally durable and beautiful.

A wide variety of sizes and styles are available. Our greenhouse kits can be in lean-to and freestanding styles, large or small. We can modify our kits to fit custom situations.  Please view the video below for a short introduction to the various greenhouse styles.

We have 3 Trillium models in stock as of 2/11/19. Please call to process your order.

We are a small, family business, committed to customized service before, during and after the sale of our greenhouses. Questions?
