Choosing Your Stali Greenhouse Model
Stali Classic Greenhouses
The traditional freestanding design works in any garden layout. Available in widths of 7ft or 10ft, with lengths from 5ft to 17ft. Most popular sizes are the 7x9 (£2,199) and 10x8 (£2,899). These models suit vegetable growers who need maximum floor space and ventilation.
Stali Lean-To Greenhouses
Attach directly to your house or garden wall, saving 40% of space compared to freestanding models. The 7ft wide lean-to fits perfectly on Victorian terrace walls, while 10ft models work for detached properties. Prices start at £1,499 for a 7x5 lean-to. These capture heat from your house wall, cutting heating costs by approximately 25% in winter months.
Stali Dwarf Wall Greenhouses
Combine a 2ft brick or timber base with glass panels above. This design improves heat retention by 15% and creates natural staging at the perfect working height (reducing back strain). The brick base also protects lower glass from accidental damage. Expect to add £300-500 to standard model prices for dwarf wall construction.
Stali Greenhouses with Storage
Select models include a separate storage compartment with solid panels, ideal for tools, compost, and greenhouse accessories. This keeps your growing space organised without needing a separate shed.
Selecting the Right Size for Your Garden
Measure your available space carefully—Stali sizes are quoted as width x length (e.g., 10x17 means 10ft wide, 17ft long). Check each product's "Minimum Base Size" specification, which includes the door opening and any overhanging eaves. A 7x9 greenhouse typically needs a 7ft 6" x 9ft 6" base.
Most gardeners underestimate the space they need. A 6x8 greenhouse feels cramped once you add greenhouse staging and shelving. We recommend choosing one size larger than your initial estimate. The 8x10 and 10x12 models offer the best balance of growing space and cost efficiency, with prices ranging from £2,499 to £4,299.
For base preparation guidance, see our comprehensive greenhouse base information which includes detailed diagrams for different foundation types.
Customising Your Stali Greenhouse
Glazing Upgrades
Standard 4mm toughened glass is included, but self-cleaning glass (available on 10ft wide models) uses a special coating that breaks down dirt when exposed to sunlight. This reduces cleaning frequency from monthly to twice yearly—worth considering if your greenhouse backs onto trees or is under a flight path.
Colour Options
Choose from 30 RAL colours at no extra cost. Popular choices include Moorland Green (RAL 6005) for traditional gardens, Anthracite Grey (RAL 7016) for contemporary settings, and Black (RAL 9005) for Victorian restorations. Powder coating is baked on at 200°C, lasting 20+ years without fading.
Ventilation
Standard models include one roof vent. Add extra vents (£89 each) or automatic vent openers (£45) for hands-free temperature control. Professional growers recommend one vent per 6ft of length for optimal air circulation.
Heating
Browse our greenhouse heaters to extend your growing season. A 2kW electric heater costs approximately 40p per hour to run and maintains 5°C minimum temperatures in a 8x10 greenhouse during typical UK winters.
How We Make Accessory Selection Simple
On each greenhouse product page, we list only compatible accessories—from staging and shelving to extra vents and rainwater kits. You'll see exactly what fits your chosen model before adding it to your basket. This eliminates the frustration of ordering incompatible parts. We've been selling greenhouses for over 15 years and know precisely which accessories work with each Stali model—saving you time and costly returns.
Frequently Asked Questions About Stali Greenhouses
-
What kind of base do I need for a Stali greenhouse?
Stali greenhouses require a firm, level base made from concrete slabs, a concrete raft, or timber framework. The base must be within 5mm of level and support the entire footprint plus 3 inches extra around all edges. Read our detailed greenhouse base buying guide for step-by-step instructions on DIY and professional installation options.
-
How much do Stali greenhouses cost?
Prices start at £1,499 for a 7x5 lean-to model and range up to £7,999 for a 10x17 classic with premium features. Most popular models (8x10 to 10x12) cost between £2,899 and £4,299. All prices include 4mm toughened glass, delivery, and the 12-year warranty. Optional extras like self-cleaning glass, coloured frames, and cresting are priced individually.
-
Is professional installation available?
Yes, professional installation is available across UK mainland postcodes at competitive rates (quoted based on your postcode and greenhouse size). Our installation teams are greenhouse specialists who typically complete a 8x10 model in 6-8 hours. They'll also advise on base preparation and positioning for optimal sunlight. Call 0800 098 8877 for an installation quote.
-
What does the 12-year warranty cover?
The warranty covers all aluminium framework components, glazing bars, door mechanisms, and fixings against manufacturing defects for 12 years from purchase. Glass breakage from accidental damage isn't covered, but glass panels are available as spare parts. The warranty is only valid for UK installations and requires following our base preparation guidelines.
-
How difficult is Stali greenhouse assembly?
Most customers with DIY experience complete assembly in 8-12 hours over a weekend using basic tools (screwdriver, drill, spirit level). Stali's bolt-together design is more straightforward than some competitors' systems. You'll need two people for safe glass handling and frame alignment. Full illustrated instructions are included, and our technical team offers phone support during assembly.
-
Can I add accessories like staging or extra vents later?
Absolutely. All accessories remain compatible with your greenhouse for years after purchase. Greenhouse staging can be added, removed, or reconfigured as your growing needs change. Extra roof vents can be retrofitted by removing a glass panel and installing the vent frame—no structural modifications needed.
-
What's the difference between 7ft and 10ft wide models?
Width affects internal space and cost. 7ft wide models (£1,499-£3,499) suit smaller gardens and provide enough space for staging on one side with a central path. 10ft wide models (£2,699-£7,999) allow staging on both sides with a comfortable central walkway, essentially doubling your growing capacity. The 10ft frames are also structurally stronger for exposed locations.
