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, freestanding and attached 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.
