Somewhere between a large glass cloche and a small steel frame greenhouse, round cold frames are protective enclosures which provide invaluable protection for seeds, cuttings and tender plants, especially during cold months.

Round cold frames, also known as hoop buildings, are ideal for starting seedlings or transitioning steel frame greenhouse plants prior to outdoor planting. Round cold frames can make a gardener's early spring and autumn much more active for growing, allowing peas and beans to get off to an early start, or giving tender young plants time to harden off, ready for the summer months.

The lowest-cost greenhouse is a single-slope roof structure (sunglass greenhouse), which not only saves space for small gardens, but also allows the greenhouse to use wall insulation.

It is generally believed that for small independent greenhouses, it is best to use a wooden base and a traditional equal-slope roof structure. Hemispherical or other similar complex structure greenhouses can use the sun's heat and light more efficiently, and the greenhouse heats up faster. However, greenhouses with this structure also cool down quickly, require relatively large investment, and provide too little growth space.

Most modern greenhouses are made of aluminum, but there are a few manufacturers who produce traditional wooden greenhouses. Wooden greenhouses have good thermal insulation effects, high yields, and are generally not susceptible to damage by strong winds. For old-fashioned residences, old-fashioned greenhouses are more suitable.
