Glass Greenhouse Solar Kits vs Traditional: Winter Bill Savings
Learn how solar-integrated glass greenhouses cut winter energy costs by 30–50%, and when climate, structure, and installation factors make traditional smarter.
A small DIY greenhouse using plastic sheeting might cost as little as $1,000, while a fully equipped glass greenhouse with heating and ventilation can exceed $30,000, especially if you go down the route of hiring a contractor. Greenhouse costs also vary based on how you build it: from-scratch DIY, pre-made kits, or turn-key custom builds.
Keep in mind that a $5,000 polycarbonate greenhouse with a 15-year lifespan comes out to about $333 per year in depreciation, while a $10,000 glass structure over 30 years also equals $333 per year. Same annual cost, different upfront investment.
A dome greenhouse is round with a domed peak. Its round shape helps absorb heat and light. It is made using a metal or PVC frame covered with glass or plastic sheeting. One square foot costs between $10 and $25 to build. A spacious domed greenhouse provides enough space for plants to grow and people to walk through.
Permits are usually required for greenhouses over 120 sq ft, those built on permanent foundations, or structures with electrical or heating systems. Costs typically range from $50 to $500, depending on size, required inspections, and local laws. Timelines: Getting a permit can add 1 to 4 weeks to your project.
