Custom Wrought Iron Greenhouses & Victorian Conservatories
A wrought iron greenhouse is not a garden shed with windows.
It is a permanent architectural structure — a place where sunlight floods in through tempered glass, where roses climb hand-forged iron columns, and where you can host a dinner party in January surrounded by orange trees.
At Yun Sculpture, we forge heavy-duty iron greenhouses and Victorian conservatories built to last 100+ years. Every frame is hot-dip galvanized and powder coated — double protection that cheap paint-sprayed tubes simply cannot match.
Whether you need a freestanding Victorian greenhouse for your estate garden, a lean-to conservatory attached to your home, or a glass-enclosed wedding pavilion for your hotel — we build it to your exact dimensions.
Victorian Iron Conservatories — The Crown Jewel of Any Garden
The Victorian conservatory is the most iconic iron glass structure. Its high domed roof, ornate scrollwork, and panoramic glass walls create a breathtaking focal point in any landscape.
Our Victorian conservatories are inspired by the great 19th-century English glasshouses — structures like the Palm House at Kew Gardens, where architects first combined iron frames with vast expanses of glass.

Antique White
elegant and romantic, our best seller for wedding venues
Matte Black
dramatic and modern, popular for estate entrances
The Dome
The signature feature is the arched dome roof. We forge each rib by hand, then install curved tempered glass panels that follow the arc precisely. The result: a structure that looks like a birdcage made of iron and light.
Classic Green
The traditional English greenhouse color, blends naturally with gardens
For open-air iron gazebos without glass panels, see our Wrought Iron Gazebos collection.
Rectangular Iron Greenhouses & Glass Sunrooms
Not every garden calls for a dome. A rectangular iron greenhouse offers maximum interior space with clean, architectural lines.
These structures work as:
Plant greenhouses
Grow citrus, orchids, or vegetables year-round in a climate-controlled glass enclosure.
Sunrooms
a bright, warm living space attached to your home, perfect for morning coffee or reading.
Event spaces
restaurants, hotels, and wineries use our rectangular conservatories to seat 50–300 guests under glass.
Size Range We build from 3 × 4 meters (compact garden greenhouse) to 8 × 20 meters+ (commercial event pavilion). Every dimension is custom — we match your existing slab or foundation exactly.Not sure whether you need a greenhouse, conservatory, or orangery? Our Orangery vs Conservatory vs Greenhouse guide explains the differences.
Lean-to Conservatories — Attached to Your Home
A lean-to conservatory shares one wall with your existing house. It is the most practical and affordable option for homeowners who want to add a sunlit room without a full extension.
The iron frame attaches directly to your exterior wall. The glass roof slopes down from the house roofline, creating a seamless transition from indoors to garden.
French Greenhouse & Gothic Arch Designs
Beyond the Victorian dome and the rectangular box, we also forge:
French Greenhouse
Characterized by arched windows, symmetrical proportions, and refined ornamental details. Often white, with a pitched roof and finials. The essence of a Provençal country estate.
Gothic Arch
Pointed arches replace round arches. Tall, narrow glass panels create a dramatic, cathedral-like interior. Ideal for growing tall plants or creating a theatrical event space.
Why Choose Wrought Iron Over Aluminum for a Greenhouse?
Most greenhouses on Amazon or at Home Depot use thin aluminum frames. They are light, cheap — and they bend, shake, and degrade.
A wrought iron greenhouse is a permanent building, not a seasonal tent.

| Wrought Iron (Ours) | Aluminum (Mass-market) | |
| Weight | 1,000–5,000 kg | 30–100 kg |
| Wind resistance | Hurricane-rated | Bends in strong storms |
| Lifespan | 100+ years | 10–20 years |
| Rust protection | Hot-dip galvanized + powder coated (dual layer) | Anodized or painted (single layer) |
| Customization | Any size, shape, ornament | Fixed catalog sizes |
| Aesthetic | Hand-forged scrollwork, Victorian details | Industrial / utilitarian |
| Value | Increases property value | Depreciates |
Our Dual-Layer Protection Process:
Step 1: Hot-Dip Galvanizing
We submerge the entire iron frame in a bath of molten zinc at 450°C. The zinc bonds metallurgically with the iron, creating a corrosion barrier that lasts 30–50 years even in coastal climates.
Step 2: Electrostatic Powder Coating
After galvanizing, we apply plastic powder using an electrostatic spray gun. The powder particles are attracted to the grounded metal surface, creating a uniform coat. We then cure the piece in an oven at 180–200°C, melting the powder into a hard, smooth, UV-resistant finish. Unlike liquid paint, powder coating does not drip, run, or peel.
This two-step process is why our structures survive decades outdoors without a single rust spot — while cheap competitors start flaking paint within 2–3 years.
Tempered Glass Options for Every Climate
We offer multiple glazing options to match your climate and use case:
Single-Layer Tempered Glass (5–8mm)
Standard for mild climates. Excellent light transmission. Strongest option for hail and impact resistance.
Double-Layer Insulated Glass (5+9A+5mm)
Two panes with an argon-filled gap. Dramatically reduces heat loss in winter and heat gain in summer. Recommended for cold climates or year-round living spaces.
Low-E Coated Glass
A microscopically thin metallic coating that reflects infrared heat back into the interior. Keeps the conservatory warm in winter without blocking visible light.
All our glass is tempered safety glass — if it breaks (unlikely), it shatters into small blunt pebbles, not dangerous shards.

Frequently Asked Questions About Iron Greenhouses
What is the best metal for a greenhouse frame?
Wrought iron is the strongest and most durable option for a permanent greenhouse. It supports heavier glass panels than aluminum, resists wind loads far better, and can be forged into decorative shapes. The main drawback — rust — is eliminated by our hot-dip galvanizing + powder coating process. Aluminum is lighter and cheaper, but it is weaker, cannot be ornamentally forged, and looks industrial rather than architectural.
What is the difference between a greenhouse, a conservatory, and a sunroom?
A greenhouse is designed primarily for growing plants. Temperature and humidity are optimized for horticulture. A conservatory is a glass-enclosed living space — it has a finished floor, furniture, and climate control for human comfort. A sunroom is similar to a conservatory but typically has solid walls on the lower half with glass above, and attaches to the house. We build all three types.
How much does a custom wrought iron greenhouse cost?
Pricing depends on size, complexity, and glass type. As a general guide: a standard 4×5m Victorian conservatory with single-pane tempered glass starts around $15,000–$25,000 (factory-direct, EXW). Larger or more ornate structures with insulated glass can reach $50,000–$100,000+. Contact us for a detailed quote based on your dimensions.
Can I use a wrought iron greenhouse as a wedding venue?
Absolutely. White Victorian conservatories are one of our best sellers for hotels and event venues. The glass walls flood the interior with natural light, and the ironwork creates a romantic backdrop for ceremonies and photography. We build event-size structures up to 8×20 meters or larger.
How long does a wrought iron greenhouse last?
With proper galvanizing and powder coating, a wrought iron greenhouse lasts 100+ years. Many Victorian-era iron greenhouses in England — like the Palm House at Kew Gardens (built 1844) — are still standing and functional after nearly 200 years. By contrast, a typical aluminum greenhouse lasts 10–20 years before joints loosen and seals fail.
Are iron conservatories cold in winter?
With single-pane glass, yes — they lose heat quickly. That is why we recommend double-layer insulated glass (with argon gas fill) for any conservatory used in winter. Combined with Low-E coating and underfloor heating, a well-built iron conservatory stays comfortable year-round, even in USDA zones 4–5.
Do I need a foundation for an iron greenhouse?
Yes. A wrought iron greenhouse weighs 1,000–5,000 kg and requires a reinforced concrete pad or a brick dwarf wall foundation. We provide foundation specifications and anchor bolt placement drawings with every order. See our foundation guide for details.
What is a Victorian greenhouse called?
Victorian greenhouses are also called conservatories, glasshouses, or orangeries, depending on their design and use. A conservatory is glass-enclosed on all sides and typically used as a living space. An orangery has more solid walls with glass mainly on the roof and was historically used to overwinter citrus trees. A glasshouse is the British term for a greenhouse. See our orangery vs conservatory guide for the full comparison.
