This guide walks you through everything you need to know to choose the right greenhouse for beginners.

Types of Greenhouse

Freestanding Greenhouses

The classic choice. A freestanding greenhouse sits independently in your garden and can be positioned wherever suits you best — usually a south-facing spot that gets maximum sun. These offer the most internal space and work best in larger gardens. Browse the full range of greenhouses.

Lean-To Greenhouses

A lean-to greenhouse is built against an existing wall — typically the south-facing wall of your house. The wall provides free passive heat, making lean-tos excellent for growing tender plants through the winter. They're also compact and well-suited to smaller gardens.

Mini Greenhouses

Perfect for balconies, patios and very small gardens, a mini greenhouse takes up minimal floor space while still giving you the growing conditions you need for starting seeds and overwintering plants. Great as a first greenhouse if space is tight.

Materials: Aluminium vs Wood

Aluminium Frame Greenhouses

• Lightweight and low maintenance
• Rust-resistant — lasts for decades
• Glazing bars are slimmer, letting in more light
• Usually the more affordable option
• No painting or treating required

Timber Frame Greenhouses

• Warmer and more attractive — great in traditional gardens
• Better natural insulation than aluminium
• Requires annual painting or staining
• Heavier construction — more robust feel

For most beginners, an aluminium frame greenhouse is the practical choice — lower cost, minimal maintenance, and excellent performance.

Size Guide

The golden rule: buy bigger than you think you need. Greenhouse space fills up remarkably quickly, especially once you discover how much you enjoy growing.

• 4×6ft (mini/starter): Perfect for getting started — tomatoes, herbs, seedlings
• 6×8ft (small): A proper growing space — most beginners start here
• 8×10ft (medium): Room for dedicated beds plus staging — the sweet spot
• 10×12ft and above: Serious growing — vegetables, cut flowers and more

What to Grow First

Start with these beginner-friendly crops that thrive in a greenhouse:

• Tomatoes: Greenhouse tomatoes are significantly better than shop-bought
• Cucumbers: Love the warmth and humidity of a greenhouse
• Chillies and peppers: Need heat to fruit well — the greenhouse delivers it
• Herbs: Basil, coriander and parsley all appreciate the shelter
• Seedlings: Start everything from seed before planting out — massively extends the season
