6x4 Greenhouse
A 6x4 greenhouse is perfect for growing more in limited spaces. Its slim shape fits neatly along fences or walls, while offering room for seedlings, potted plants, or veggies. Quick to heat and space-efficient, it’s a smart, compact choice for small gardens.
Why Choose a 6 x 4 Greenhouse?
A 6 x 4 greenhouse is an excellent option for gardeners who want practical growing space without sacrificing too much room in the garden. With its narrow width and extended length, this layout is perfect for placement along fences, walls, or narrow garden paths. You get enough internal space for a productive growing setup – ideal for herbs, lettuces, seedlings, or seasonal vegetables – while still maintaining open space elsewhere in your outdoor area.
The 6 x 4 format is particularly popular in urban gardens and compact suburban plots, where every square metre counts. You’ll have room for vertical shelving, potting benches, and walk-in access in many models. It’s also easier to heat and ventilate than larger greenhouses, making it energy-efficient and manageable all year round.
Whether you’re a first-time greenhouse buyer or downsizing from a bigger model, a 6 x 4 greenhouse offers an ideal balance between usability and compact footprint.
6 x 4 - Fits Narrow Gardens
One of the biggest advantages of the 6 x 4 greenhouse is its shape – the long-and-narrow footprint makes it ideal for placement against a south-facing fence, brick wall, or garage. This not only saves space but also offers the benefit of additional warmth and wind protection from the adjacent structure.
Placing your greenhouse along a wall helps improve temperature stability, and when combined with insulation or polycarbonate panels, it’s possible to grow throughout colder months with minimal energy input. The 6-foot length gives you flexibility for placing shelves or grow tables, while the 4-foot width keeps the structure unobtrusive in smaller gardens.
Because of its efficient footprint, this size is also great for side gardens, pathways, or dividing a larger garden into separate zones – growing in one, relaxing in another. You can easily integrate the greenhouse into your landscaping without it dominating the space.
Compact yet spacious inside, the 6 x 4 is one of the most placement-friendly sizes for modern gardeners with limited but valuable outdoor space.
Material Options – Polycarbonate, Glass, or Plastic?
Our 6 x 4 greenhouses are available in a variety of materials to match your needs and preferences. Each type has its strengths, so it’s important to consider your priorities when choosing:
Polycarbonate greenhouses offer lightweight construction, UV protection, and excellent insulation. Twin-wall panels diffuse light and retain heat well, making them perfect for year-round use and family-friendly gardens.
Toughened safety glass greenhouses deliver a traditional look with crystal-clear panels and robust durability. They're great for gardeners who want maximum visibility and elegance in their setup.
Plastic-covered greenhouses (typically with a PE or PVC film) are a more affordable, lightweight solution, often used for seasonal growing or where portability is important.
All models include sturdy aluminium or galvanised steel frames, with accessories available such as shelving, thermometers, shading kits, and automatic window openers. Whether you prefer a more permanent installation or a flexible, budget-conscious solution, the 6 x 4 format adapts well to all material choices.
6 x 4 vs 4 x 6 – What’s the Difference?
Customers often ask: What’s the difference between a 6 x 4 and a 4 x 6 greenhouse? While both offer the same total floor area (approx. 2.2 m²), the shape and usability are quite different.
A 6 x 4 greenhouse is longer and narrower, making it perfect for installation along a fence or wall. This layout provides a more linear internal space, which many gardeners prefer for organising planting beds on one side and tools or access on the other. It’s also ideal for tight or awkward spaces where width is a constraint.
A 4 x 6 greenhouse, on the other hand, offers more internal depth and may feel more "room-like” inside. It often suits more central garden placement or wider patios. If you plan to work side-by-side or install central shelving, a 4 x 6 may offer better ergonomics.
In the end, it comes down to how you plan to use your greenhouse and how your space is shaped. Both options are compact, efficient, and beginner-friendly – and we offer both in a wide range of materials, colours, and roof styles. Need help choosing? Our team is happy to guide you.
