Custom Greenhouses

Custom Commercial

Ceres commercial greenhouse design includes custom commercial and passive solar greenhouse structures that are designed for spaces over 3,000 sq. ft. These dimensions are customized to suit the site and operational layout. Our custom commercial builds are constructed with steel framing, the strongest and longest-lasting framing material. Framing can span up to 80′ (depending on snow loads), allowing greater flexibility with layout options. Custom projects have longer design times and slightly higher build costs than our kit options. Pricing starts at $45 per square foot.

Custom Residential

We provide consulting, design and architectural drawing, and engineering services for custom greenhouses. Custom greenhouse designs are based on our passive solar design principles. Size and potential complexity of a project are determining factors for how customized a project can be. We also work with clients’ existing architects or engineers.

Frequently Asked Questions

The cost of a year round greenhouse depends on a lot of things, primarily the size, how you source the materials and who builds it. To give you a general idea, some growers use recycled materials and do all the work themselves and spend as little as a few hundred dollars for a residential solar greenhouse. More commonly, growers buy new materials that will last longer, and outsource some or most of the work. A common range is to spend $5,000 to $30,000 for a durable and energy-efficient backyard greenhouse. Ceres greenhouses are often $70-75/sq. ft for materials.

This varies greatly by location, and what you are trying to grow. In areas with mild winters, passive solar greenhouses can grow year-round without any back-up heating. Greenhouses in cold areas can even grow very hardy crops year-round without heating. However, to grow a wider variety of crops, in most cold climates an energy-efficient greenhouse will require some back-up heating. This is usually turned on during a few very cold nights a year — the extreme cold snaps — when a GAHT® system, thermal mass, or phase change material is not sufficient to keep temperatures high enough.

Residential growers typically add an electric heater for the coldest times of the year. Commercial growers typically integrate propane or electric heat. We can help you integrate a back-up heater when designing your commercial greenhouse.

Yes! Attached greenhouses have many advantages, such as provide passive solar heating for the home. However, they require specialized materials and air exchanges for an energy-efficient structure. Depending on the project, we will sometimes team with architects and local contractors in building durable, beautiful and efficient greenhouses.

Many solar greenhouse designers recommend using a roof angle that is perpendicular to the angle of the sun in the winter. While this does indeed maximize light transmission in the winter, the effect of a lower angle is not severe. We explain this relationship much further in our blog, Choosing the Best Roof Angle for your Greenhouse. Furthermore, there are a few logistical challenges to creating very steep pitch — you cannot use glass view windows on the south; it can reduce headroom or create an awkwardly tall greenhouse. Due to these pros and cons, most of our residential growers are built with a shallow angle roof. If you have a need for a steeply pitched roof, just ask us.

Yes, we work with clients all over the world. Our standard greenhouse plans, and custom designs can be applied to greenhouses in any location. We often customize the greenhouse to optimize performance for year-round growing in your climate.
