Since 1982, Hoklartherm GmbH has been designing, engineering, manufacturing, and distributing premium greenhouses and outdoor structures throughout the world. The company began as a maker of arched greenhouses and the unique Riga design has remained popular ever since. The company was founded by an engineering graduate named Werner Hollander who had built the first prototype in his family's garden a few years earlier.

From this first arched design has come a series of incremental changes to make the Rigas among the very strongest greenhouses available anywhere. The frames have been engineered for strength and to shed off snow and the commercial-grade polycarbonate panels add extra strength to the structure. Hoklartherm now makes beautiful and unique pavilions as well which have been widely installed throughout Europe in parks, commercial settings, and luxury private gardens.

At Hoklartherm's headquarters in Apen, Germany, a section referred to as "Greenhouse World" opened to the public in 2012 to showcase all of their unique designs in one place. At this site is the Hoklartherm state of the art factory that employs all the latest quality control techniques and aluminum processing equipment to ensure the very highest and most precise build quality. Hoklartherm is now Germany's largest manufacturer of premium residential and commercial greenhouses and its structures have been enjoyed by happy customers all over the world.

Exaco Trading Co. began in 1987 as importer and distributor of a home paint mixing accessory called the Exomixer. Since then the family owned company has expanded its line considerably to include many different home and garden products, including some of the very best greenhouses from Europe. The company is led by CEO Kimberly Tyson Cook, formerly an award winning business reporter for the Austin American-Statesman, and Andrew Cook, the VP of Sales and Marketing.

Andrew travels to Europe to check on the manufacturers in person several times a year and has become a leading national authority on all things greenhouse related. He has appeared in many gardening articles and television programs nationally. In fact Andrew is available for phone support for customers during the installation of any of the premier greenhouses that Exaco distributes from its large Austin, TX warehouse.

While the process of assembling a greenhouse might seem daunting, these kits are designed to be assembled by an experienced contractor. Depending on the skill level of the contractor, the size of the structure, and the number of options you order, putting together a kit can take two or three adults one full weekend or perhaps three days.

Most customers will opt to hire a local handyman or contractor to simplify this process, and the affordable price of the kits makes it easy to do this. They can be readily found online at sites like AngiesList or HomeAdvisor or the neighborhood app NextDoor. A version of the assembly manual is available as a PDF near the bottom of this page to give you a better idea of the process.

Site Preparation - Customers often tell us that the trickiest part of the the process is making sure that they have a good foundation upon which to build the structure. This foundation should extend around the perimeter of your greenhouse. It is ideal to have the foundation be as level and square as possible.

Concrete pavers or pressure-treated wood with crushed stone is often used, though actually pouring concrete will give the most permanent installation. The greenhouse is designed to last for decades, and pressure-treated wood typically will fail well before that when used in outdoor applications, particularly in the ground.

Exaco recommends that all the grass and weeds be removed from inside the greenhouse before assembly and that the area be covered with a weed control mat. Installing the greenhouse on a concrete slab may seem like an easier way to get started, but it's actually less than ideal, as the greenhouse floor should be free draining.

Standing water on concrete can freeze easily in winter months, causing a slip hazard. And concrete slabs don't help regulate the temperature inside the greenhouse as well as other floors such as pea gravel, pine straw, riverbed stones, or just regular earth. Customers typically will create some sort of path down the middle of their greenhouse with flag stones, bricks, or even decking.
