Halls Popular 6x4 Aluminium Greenhouse review
First-time growers wanting an affordable, compact aluminium greenhouse for a small garden.
By Tom Rowland · Updated 20 July 2026 · Price checked against our tracker
A dependable, keenly-priced starter greenhouse: the aluminium frame and long warranty make it a sensible entry point for a small plot. It rewards careful assembly on a level, sheltered spot and a firm base.
Approximate typical UK street price as of Jul 2026, drawn from UK retailer listings (Halls Greenhouses, Greenhouse Stores, GardenSite, The Greenhouse Shop). The silver-frame horticultural-glass model starts around £400; the green-frame version and toughened-glass variants sit nearer £450-£550. £450 is a sensible mid-point across the common configurations.
