Description
Maximise your growing potential, even in smaller gardens, with the 8 x 4 Mercia Woodsman Lean-To Polycarbonate Greenhouse. Designed to fit neatly against a wall or fence, this greenhouse offers a practical solution where space is limited without compromising performance.
Crafted in the UK from sustainably sourced timber, the structure is built with durable 12mm shiplap cladding and a robust 2”x2” frame for strength and longevity. The thermally insulating polycarbonate glazing helps regulate temperature, retaining warmth during cooler months while protecting plants from harsh sun in the summer. Shatterproof and lightweight, it provides a safer alternative to glass, perfect for family gardens.
The pent roof design allows rain to run off easily, while the lean-to style uses an existing wall, helping to capture additional warmth and shelter. A roof vent encourages airflow, preventing overheating and keeping humidity levels balanced for healthier plant growth.
This greenhouse is designed to adapt to your space, with the door panel offering flexible positioning during assembly. It is finished with traditional ironmongery for a classic touch and blends practicality with timeless style. Supplied with all fittings and clear instructions, assembly is straightforward whether you are a seasoned grower or starting your first greenhouse.
It is built to withstand the elements and is protected by a 10-year anti-rot guarantee. It offers a reliable space to cultivate herbs, seedlings, and tender plants throughout the year. With prompt UK delivery, you’ll be ready to grow quickly.
Premium Greenhouse Base
Designed for superior stability, the enhanced greenhouse base offers a 20% wider foundation than standard options, providing a solid, long-lasting support system. This cost-effective upgrade ensures your greenhouse remains sturdy and secure for years to come.
Greenhouse Height Extension
Expand your greenhouse with our Height Extension Pack, designed to increase headroom for greater comfort and ease of movement. The extra height improves air circulation, encouraging healthier plant growth while offering more space for taller plants, hanging baskets, and shelving. This upgrade not only enhances functionality but also creates a more open and spacious environment, making your greenhouse an even more enjoyable place to work.
Also available with different glazing finishes:
8 x 4 Mercia Woodsman Lean to Wooden Greenhouse - Styrene
8 x 4 Mercia Woodsman Lean to Wooden Greenhouse - Toughened Glass

Make The Most of Your Wooden Greenhouse
The slimline 8 x 4 design is ideal for making the most of a narrow outdoor space. Position sun-loving plants like tomatoes and peppers towards the back, closer to the warmth of the wall, and keep smaller pots and herbs near the front for easy access. Wall-mounted shelving (available separately) is a great way to utilise the vertical space, helping you grow more without cluttering the floor.
The lean-to design naturally benefits from the heat the adjoining wall retains, but ventilation is still key. Adjust the roof vent and door to regulate airflow and prevent overheating in warmer months. This greenhouse's insulating polycarbonate glazing is perfect for extending your growing season. Start seedlings earlier in spring and keep herbs and leafy greens flourishing well into autumn. With its sturdy timber frame and space-saving layout, this lean-to greenhouse turns even the smallest corner of your garden into a thriving, growing hub.
