About Our Elite Supreme Greenhouses
Elite Supreme Greenhouses represent a step up for serious growers who need professional-grade space without stepping into full commercial territory. These 10ft 5" wide aluminium structures combine generous width with unlimited length options, creating expansive growing environments that suit wheelchair users, commercial propagators, and passionate gardeners alike.
💡 The heavy-duty cantilever diagonal bracing system reinforces the structure without requiring thicker (and costlier) aluminium profiles, delivering exceptional strength in a cost-effective package. This bracing works seamlessly with Elite’s Diamond Staging, allowing shelving to sit flush against the wall without gaps—a common annoyance in lesser competitor models.
You'll also find practical features throughout: double sliding doors with integrated locks, built-in guttering that channels rainwater effectively, and a low-threshold entrance that eliminates the trip hazard common in traditional greenhouses. The 7ft 11" ridge height provides standing room for most adults.
Available in 11 powder-coated colours from classic green to contemporary graphite grey, these greenhouses suit any garden aesthetic. Elite backs every Supreme with their 20-year framework guarantee and manufactures each unit in Britain using 60+ years of greenhouse expertise. Free UK mainland delivery comes standard, with professional installation services available for those who prefer expert assembly.
Choosing Your Elite Supreme Greenhouse
Size selection for the Supreme range is straightforward: width stays constant at 10ft 5", so you're choosing length based on your growing ambitions. The Elite Supreme 10x6 suits gardeners transitioning from smaller 6ft or 8ft wide models, whilst the Elite Supreme 10x10 and Elite Supreme 10x12 represent the sweet spot for hobby growers needing serious space. Commercial growers or those running plant nurseries often opt for the Elite Supreme 10x16 or longer, where the cost-per-square-foot becomes increasingly attractive.
For these longer models, many customers add an internal partition. This allows you to "zone" your greenhouse—keeping one section comfortably heated for propagation while using the other for cooler overwintering, all under one roof.
Glazing choice significantly impacts both performance and budget. Standard horticultural glass keeps prices accessible (starting from £910), but most customers upgrade to toughened safety glass for peace of mind—particularly important in family gardens or exposed locations. The 4mm toughened glass shatters into small granules rather than dangerous shards, meeting UK safety standards for public spaces. Polycarbonate glazing offers superior insulation (approximately 40% better heat retention than glass) but scratches more easily and may discolour after 10–15 years.
⚠️ Base requirements deserve careful attention for these wider structures. Unlike standard 6ft greenhouses, a 10ft span generates substantial roof loads and wind stresses. You'll need a perfectly level, permanently square base—either a concrete slab or paving slabs on compacted hardcore with perimeter footings. Our greenhouse base preparation guide provides detailed instructions, or you can bundle professional installation which includes base construction.
Comparing the Supreme to other 10ft options helps clarify your choice. The Elite Titan 1000 Greenhouse uses thicker "Core-Vect" profile bars for ultimate strength, making it ideal for extremely exposed coastal or hilltop sites. The Supreme achieves comparable strength through heavy bracing at a lower price point, suiting sheltered to moderately exposed gardens. If you need even more width, the Elite Classique Greenhouse offers a substantial 12ft span.
Frequently Asked Questions about Elite Supreme Greenhouses
-
How much do Elite Supreme Greenhouses cost?
Prices start from £910 for the smallest 10x6 model with standard horticultural glazing and extend to £3,769 for larger models with premium toughened safety glass. Most popular configurations with toughened glass fall between £1,800–£2,400, representing excellent value for a professional-grade 10ft wide structure.
-
Which Elite Supreme size should I buy?
Choose based on your growing volume and garden space. The 10x10 (100 sq ft) suits serious hobby growers, the 10x12 (120 sq ft) accommodates small commercial operations, whilst 10x14 and longer models suit plant nurseries or dedicated propagators. Allow 2ft clearance around all sides for maintenance access.
-
Do Elite Supreme Greenhouses need a separate base?
Yes, absolutely. The 10ft 5" width generates significant structural loads requiring a permanent, perfectly level base. Elite provides detailed base plans with your order, specifying either a concrete slab or paving slabs on compacted hardcore with perimeter footings to prevent settlement.
-
What's the difference between toughened glass and polycarbonate glazing?
Toughened glass offers superior clarity, doesn't scratch or discolour, and shatters safely if broken—ideal for family gardens. Polycarbonate provides 40% better insulation for year-round growing and weighs less, but will eventually cloud and scratch. Most Supreme customers choose toughened glass for its 25–30 year longevity.
-
