The Conley Hobby House is manufactured using the same rolled-form components utilized in Conley's commercial greenhouse structures. Unlike so many other hobby greenhouses, this greenhouse is fully engineered and will last a lifetime. All installation instructions and prints are geared towards a qualified builder. It is highly recommended that if you don't have the skills that you hire a qualified builder to assemble your Conley Hobby Greenhouse.

Roll Form

The arches and purlins in the Hobby House feature Superior strength ROLL-FORM steel for unmatched structural integrity. ROLL-FORM sections direct more strength to the longer axis of the metal. Conley's use of COLD FORMING procedures protect the metal's galvanizing features.


Conley’s continuous coil process allows you to access sections of steel as long as necessary to fit your unique needs. Incorporating continuous coils of pre-galvanized metal, ROLL-FORM mills incur virtually no material waste and can generate sections of steel as long as necessary. This means that Conley’s can form wider houses out of a single piece of steel versus some manufacturers who are forced to “splice” their trusses together.


Components of the Hobby House's structures are shipped to you pre-punched and cut to length, for easy bolt-together assembly. Step by step installation instructions are included. Given the shapes of the ROLL-FORMED components, they are naturally able to be nested one into the other during shipment, substantially reducing freight rates. Coverings consist of 6mm, clear, Twin wall UV resistant sheets complete with energy efficient insulation qualities and a 10-year warranty against discoloration.
