The size of a greenhouse is a key factor influencing its overall cost. Larger greenhouses generally require more materials and labour, contributing to higher expenses. The impact of size on cost is notable in various aspects. First, construction materials like framing and glazing will be needed in larger quantities. Additionally, bigger structures often necessitate more robust foundations, adding to the expense.

To provide a general perspective, consider the following price ranges based below:

  • Small greenhouses: These compact structures offer an affordable entry point. Ranging from 6×4 to 10×12 feet, prices may range from £299 to £1,500, depending on materials and extra features.
  • Medium greenhouses: With dimensions spanning 12×16 to 14×20. Medium-sized ones strike a balance between space and cost. Expect a price range from £800 to £2,500 – again, depending on materials and features.
  • Large greenhouses: Extending beyond 20×24, bigger units cater to commercial use. Prices for such structures can range from £3,000 and above.

Understanding the impact of size on cost is key to budgeting for your ideal greenhouse.

Greenhouses offer a diverse range of styles to cater to various gardening preferences. Let’s start with traditional greenhouses, which are known for their classic designs. These structures provide a timeless aesthetic and may have a price range of £1,000 – £2,500. Take, for instance, the BillyOh Switch Apex Wooden Greenhouse. This unit is available in five sizes, each falling within this price bracket.

Next is the learn-to greenhouses notable for their ‘attach to existing structures’ design. Such designs offer space efficiency and can be priced from £300 to £1,500, depending on the material. A notable example are lean-to greenhouses.

Finally, potting sheds combine storage and growing space, falling within the range of £700 – £1,500. Every style has distinct features that affect both functionality and cost. This lets you pick the one that aligns with your gardening goals and budget.

Framing and glazing materials

The choice of framing materials also plays a pivotal role in durability and cost. Aluminium, steel, and wood are the primary options. Aluminium is lightweight and corrosion-resistant, often leading to a moderate price range. Steel, known for its robustness, tends to be costlier but ensures long-term stability. Wood, with its classic appeal, falls within a variable price range depending on the wood type used.

Understanding the significance of glazing in greenhouse construction is equally essential. The glazing material affects factors like insulation and light diffusion. Glass, known for its clarity and durability, usually contributes to a higher cost. Polycarbonate, lightweight and shatter-resistant, often provides a balance between cost and performance. Polyethylene, a plastic film, is the most budget-friendly option. However, it may require more frequent replacement.

Shelving provides organised space for plants, tools, and accessories. However, it may come with extra expenses, ranging from £50 to £200, depending on the complexity. Ventilation options, such as automatic vent openers, improve airflow and climate control. Then again, this can contribute to a price range of £30 to £150.
