Small greenhouses and mini greenhouses for every space

You don't need a large garden to enjoy protected growing. A mini greenhouse can provide valuable room for seedlings, herbs and vegetables while making efficient use of a smaller footprint.


The right design depends on where you want to position it and how much access and growing room you need. Freestanding greenhouses provide flexibility in the garden or on a patio, while lean-to models make use of an existing wall. Small walk-in greenhouses offer more room inside while still keeping the overall footprint compact

    Small freestanding greenhouses for patios and gardens

    A small freestanding greenhouse is a versatile choice when you have a suitable open area in your garden or on a patio. Because it does not need to sit against another structure, you have greater flexibility when choosing its position.

    Our compact freestanding models are available in different footprints, heights and glazing specifications. When comparing them, consider not only the amount of ground space available but also door access, internal height and the room you need for pots, shelving and plants.

    Small lean to greenhouses for balconies and limited outdoor spaces

    A small lean-to greenhouse makes use of an existing wall, helping you create a protected growing area without giving up as much garden or patio space.

    These compact designs are particularly useful for narrow outdoor areas and places where a freestanding greenhouse would be difficult to position. Before choosing a lean-to greenhouse, check the width and depth of the available area as well as the position of doors, windows, gutters and other features on the adjoining wall.

    Small walk-in greenhouses for extra growing space

    A small walk-in greenhouse gives you the convenience of stepping inside to tend your plants while keeping the overall footprint manageable. The extra internal space can make it easier to organise pots and greenhouse shelving and to grow several types of plant at the same time. If you want a compact greenhouse but don't want to sacrifice comfortable access, compare the footprint, sidewall height and door arrangement of the available models.

    Choose the right small greenhouse material

    The frame and glazing or cover affect how a small greenhouse looks, feels and is used. Our range can bring together permanent framed greenhouses and lighter seasonal growing solutions, allowing you to choose according to your budget, available space and intended use. When comparing materials, consider whether you want a permanent structure, how much maintenance you are comfortable with and whether you prioritise insulation, clear visibility or portability.

    Small aluminium greenhouses built to last

    An aluminium frame is a practical choice for a compact greenhouse because it combines a relatively lightweight construction with low maintenance.

    Our framed small greenhouses are available in different designs and glazing specifications, including freestanding and lean-to models. Compare the complete product specification rather than the frame material alone, as glazing thickness, doors, ventilation, dimensions and included components vary between models.

      Small plastic greenhouses for every budget

      A small plastic greenhouse is a practical and affordable way to start growing in a protected environment. Lightweight and easy to position, plastic greenhouses are available in a variety of designs to suit patios, gardens and other compact outdoor spaces. Whether you're raising seedlings, growing herbs or extending the growing season, there's a plastic greenhouse to suit your needs.

      Small polycarbonate greenhouses for year-round growing

      A small polycarbonate greenhouse combines a rigid frame with lightweight glazing. Our compact polycarbonate models use twin-wall sheets, with the exact panel thickness varying by greenhouse.

      They are available in several footprints and configurations, including freestanding and lean-to designs. If polycarbonate is your preferred glazing material, compare the dimensions, panel thickness, door arrangement and other specifications of each model before choosing.

      Small portable polytunnel greenhouses for flexible growing

      If you want a lighter growing solution, a portable mini greenhouse or compact polytunnel can provide temporary or seasonal protection without the footprint of a larger permanent greenhouse.

      These designs can be useful for raising young plants, protecting crops and creating additional covered growing space. Compare the dimensions, cover material, access and anchoring requirements to find an option suited to your outdoor space.

      Small glass greenhouse hybrid with the best of both worlds

      A small glass greenhouse combines a traditional appearance with clear glazing, making it an attractive option for customers who want their greenhouse to become a permanent feature of the garden. Our current range combine glass side panels with polycarbonate roof glazing rather than using one glazing material throughout.

      Our small greenhouse kits include everything you need to create a productive growing space at home. Depending on the model, your kit may include a durable frame, glazing panels or cover, doors, roof vents and, in many cases, a galvanised steel foundation frame for added stability. With clear instructions and precision-engineered components, setting up your greenhouse is straightforward, so you can start growing sooner.


      What can you grow in a small greenhouse?

      A small greenhouse opens up a surprising range of growing possibilities, whether you're just starting your gardening journey or looking to extend the growing season. From leafy vegetables and fresh herbs to strawberries, peppers and young plants, a protected growing environment helps shield crops from changing weather while giving you greater control over temperature and humidity. Even compact greenhouses provide enough space to enjoy homegrown produce throughout much of the year.

      Growing vegetables, herbs and tomatoes

      A small greenhouse is ideal for growing a wide variety of vegetables and herbs, including lettuce, spinach, peppers, chillies, basil, parsley and coriander. By providing protection from wind, rain and cooler temperatures, a greenhouse can help seedlings establish more quickly and support healthy growth throughout the season.


      Many gardeners also use a small greenhouse to grow tomatoes. While compact models are suitable for a few tomato plants, dedicated tomato greenhouses offer additional height and ventilation for optimum growing conditions. If tomatoes are your main crop, explore our range of tomato greenhouses to find a model specifically designed for healthy, productive plants.
