Redwood Greenhouses

Sturdi-Built Greenhouse builds the finest handcrafted redwood greenhouse kits available. Since the 1950’s, we continue to help gardeners, schools, community gardens, home office workers, artists and more to create beautiful and long-lasting greenhouses. Our greenhouses will help you to grow a variety of healthy plants year round – no matter the weather.

We make beautiful, high-quality, and heavy-duty greenhouse kits in our factory in Portland, Oregon, using the highest-quality redwood available – Clear All-Heart Redwood – and double-strength glass. It’s thanks to these excellent materials that our luxury greenhouses are naturally durable and beautiful.

A wide variety of sizes and styles are available for you to choose from. Whether you prefer redwood greenhouses that are lean-to, freestanding, or attached, large or small, you’ll be able to customize your kit to fit your situation and preferences.

Check out our YouTube channel for an introduction to Sturdi-Built services and our redwood greenhouses. Get in touch with us today to start building a greenhouse customized to your space and needs!

Lean-to Styles

Lean-to greenhouses are attached to your home or structure at the ridge of the greenhouse. Lean-tos are our specialty and we can often accommodate your unique space with a custom design if necessary. Please keep in mind that you will need at least 8′ of vertical clearance on the attaching wall to fit our narrowest standard width lean-to.

“We’ve enjoyed our greenhouse so much – I almost feel guilty about having this much fun. It helps being able to share the bounty with neighbors and family. Thank you for manufacturing such a wonderful product and then making yourself available at our beck and call. It’s a pleasure to recommend our local, Northwest, family run, Sturdi-Built. Thank you again.”

“I am planting pansies that grew all winter and are bigger than those in the store. What a life! Thanks for making all of this possible.”
KC, Iowa

“Hello! Okay, this has been a long time coming…I guess I’m guilty of playing too long in my beautiful greenhouse… I can’t tell how thrilled I am about the finished product. It’s more than I could have ever dreamed of and I couldn’t have settled for anything less. All my friends are “green” with envy and can’t believe that I have such wonderful place of solitude to visit daily. It is my oasis where my flowers and I get to dance in perfect 70 degree weather all year round! Thank you again for constructing such a well-built and most beautiful greenhouse ever!”
