A Victorian greenhouse runs $7,999 for a Janssens Junior to $60,000 and up for Alitex, checked September 20, 2026. Every brand, price, pitch and knee wall.
Comparison
Quick answer: Checked September 20, 2026, a Victorian greenhouse in the US starts at $7,999 for an Exaco Junior Victorian J-VIC 23 (38-degree pitch, 4mm tempered glass, 5 ft 2 in sidewalls) and $9,799 for a Janssens Royal Victorian VI 23 with finials included. The mid-size Royal Victorian VI 34, 10 ft 2 in by 15 ft, is $11,499 in glass or about $3,500 more with a polycarbonate roof. The T-shaped Royal Victorian Orangerie is on sale at $21,999. Redwood-framed Sturdi-Built Nantucket kits start at $18,245 and Gothic Arch's RBH Victorian runs $28,999 to $34,499 for the same footprints Janssens sells at under half the price. Hartley Botanic publishes no prices, quotes typical jobs at $30,000 to $250,000 and adds about 20 percent for shipping and installation. Alitex starts at $60,000. None of these prices include the masonry knee wall, foundation, delivery or assembly, and the cheapest kit still needs a solid, level, frost-free base before it goes up.
Best for
Buyers who want the steep-pitched, ridge-crested glasshouse look and need to know which brand delivers it at $10,000, $25,000 and $60,000 before they call for quotes.
Wrong fit
Buyers who just want the most growing space per dollar. A Victorian pays for height, pitch and ornament, not square footage.
Tradeoff
The Janssens kits give you the Victorian silhouette, tempered glass and finials at a fifth of the Hartley or Alitex price, but you own the foundation, the knee wall, the freight inspection and the assembly. The English brands include design, drawings and installation, and charge for all of it.
Checked September 20, 2026, the price of a Victorian greenhouse in the US spans from $7,999 to well past $60,000 for what is, on paper, the same idea: a tall aluminum frame with a steep glass roof, a ridge line with cresting or finials, and roof vents. The gap is not the glass. It is who builds the base, who installs it, and how much ornament and thickness you are paying for.
We don't sell greenhouses. We save you from buying the wrong one. This guide lists every brand selling a Victorian-style structure in the US today, with the price we read on the page, the roof pitch and sidewall height that define the look, and the knee wall and foundation work every one of them leaves to you. If you have not settled glass versus polycarbonate, that decision moves your budget more than the brand. For what the whole project costs beyond the kit, start with the real cost of a greenhouse.

Not sold as Victorian; the orangery look without the glass or the pitch
There is no Victorian-style kit from Outsunny, Rion or any marketplace brand. The word does not appear on their catalogs, and the cheapest structure that borrows the look is Palram's orangery, which is a polycarbonate kit with a hip roof.
How These Numbers Were Built, and When
Every price was read from the manufacturer or an authorized US retailer on September 20, 2026, with the page named in the sources. Where the importer's suggested retail and a dealer's live price differ, both are shown. Pitch, sidewall and glazing specs come from the manufacturer, not the dealer. Hartley and Alitex publish no US prices, so their rows carry only what those companies say about themselves. We have not assembled or load-tested any of these structures.
What Makes a Greenhouse Victorian
Manufacturers agree on four things. A steep roof: Janssens builds the Junior at 38 degrees and the Royal at 25, Sturdi-Built at a 6/12 pitch, Hartley describes "generous height and a steep roof pitch", and the English makers who define the style put it at 45 degrees. Narrow panes: Gothic Arch's 14-inch panes and the UK builders' "narrow glazing" are the point, not a cost saving. Ridge ornament: cresting and finials, included on the Royal Victorian and sold as an accessory by Hartley. And a base wall: the brick or block dwarf wall the frame sits on, which is where a Victorian starts looking like the conservatory in the photographs and where the real project cost begins.
Sidewall height is the number to check before falling for the pitch. The Junior Victorian's 5 ft 2 in eave is a greenhouse you stoop into at the edges. The Royal's 6 ft 7 in eave is a room.
The Knee Wall Nobody Prices
Every brand on this page assumes a wall you build. Janssens supplies no wall. Exaco's own accessory page says the Drop Door Kit is "placed on top of a perimeter wall, usually 20 to 36 inches high (24 inches might be best)", priced at $119 for hinged doors or $299 for sliding at MSRP, and the retailer listing warns the kit "does not include the small new glass panels needed above the doors, they should be ordered locally to size." Retailers also "strongly recommend upgrading to hinged doors when the greenhouse stands on a wall", which is $1,399 for a single door or $2,549 for a double at MSRP.
Hartley and Alitex do it the other way around: after the deposit they send drawings, and your builder pours the foundation and lays the wall before the crew arrives. Neither publishes a wall height or a cost. Sturdi-Built offers an 18-inch redwood basewall kit as an alternative to masonry, price on request.
We found no primary source for what a US mason charges for a 24-inch block wall around a 10 by 15 footprint, so this page does not invent one. Get it as a written line in the quote, using the quote checklist, and price the slab or footing underneath with the foundation guide. The Junior Victorian listing states the requirement plainly: "a solid, level, frost-free foundation is required."
Brand by Brand
Exaco Junior Victorian: the entry ticket
The J-VIC 23, 24 and 25 are the cheapest true Victorians sold in the US at $7,999, $8,999 and $9,999 retail against Exaco's $8,799 to $10,249 suggested prices. You get the steepest pitch of the group at 38 degrees, 4mm tempered glass in a 17-gauge tubular aluminum frame, a 4-inch base frame, and one or two automatic roof vents by size. Dealers list a 120 mph wind and 25 psf snow rating and a 15-year warranty, but those figures appear on retailer pages, not on exaco.com, so treat them as claims to confirm in writing. Ships in five to nine business days from stock; one dealer showed it sold out.
Janssens Royal Victorian: the one most people mean
The VI 23, 34 and 36 are what the search results show when you type the phrase. At $9,799, $11,499 and $13,999 in glass you get 6 ft 7 in sidewalls, a 25-degree roof, two to four roof vents plus a louvre, finials in the box, and a choice of black or fir green. The hybrid version swaps the roof glass for 10mm polycarbonate for roughly $3,500 more, which buys hail resistance and loses the look. One dealer lists a six-inch foundation frame, another four, and Gothic Arch's version five, so ask which frame ships before you pour. Special orders run four to six weeks and custom colors up to fourteen. Freight is about 1,665 lb, which is why the Janssens review spends so long on the delivery inspection.
Exaco Royal Victorian Orangerie: the T-shape
At $21,999 on sale from a $27,999 list, the Orangerie is a 12 ft 10 in by 15 ft 7 in cross-shaped Royal Victorian with 186 square feet, 6 ft 7 in sidewalls, four roof vents and two louvres. Exaco's own page for it was offline when we checked, so the price comes from a dealer only.
Sturdi-Built Nantucket: redwood instead of aluminum
Portland-built, sold direct, and the only wood option on the list. The Nantucket starts at $18,245 and a 10x12 is $22,895, with 1/8-inch glass walls, a tempered roof, a 6/12 pitch, finials and ridge scalloping. The optional 18-inch redwood basewall replaces the masonry wall for buyers who do not want to hire a mason. Lead times are not published.
Gothic Arch RBH Victorian: the same footprints at twice the price
The RBH is sold at $28,999, $32,499 and $34,499 for 10 ft 2 in by 15 ft, 10 ft 2 in by 19 ft 11 in, and 12 ft 7 in by 19 ft 11 in, the same footprints as the Royal Victorian VI 34, 36 and 46 at $11,499 to $18,999. What the extra buys is the narrow 14-inch panes and a 5-inch foundation frame. If the narrow-pane look is the reason you want a Victorian, this is the cheapest way to get it in aluminum. If it is not, the Janssens is the same house for half the money.
Hartley Botanic: quote only, install included
Hartley publishes no prices. Its own FAQ says a brochure with starting prices arrives after a phone call, its Houzz profile lists typical jobs at $30,000 to $250,000, and its cost FAQ says shipping and installation on a Victorian Lodge "adds about 20 percent". The Victorian Classic is 8 ft 6 in by 12 ft 11 in, 10 ft 11 in to the ridge, with 4mm toughened glass, cresting and finials, and a 30-year guarantee. Your builder lays the dwarf wall from Hartley's drawings. The Hartley cost guide assembles every public number, and Hartley vs Alitex compares the two English makers head to head.
Alitex: from $60,000
Alitex's US site says the Kew Collection starts at $60,000 and that bespoke structures are priced after a designer visit. The UK page states the price includes installation; the US page does not say either way. Ask. Details in the Alitex cost guide.
Palram Canopia Victory Orangery: the look-alike
Not a Victorian, and Palram does not call it one, but it is what a $3,500 budget buys if the hip-roofed orangery silhouette is the attraction. Polycarbonate roof, clear polycarbonate walls, grey aluminum, galvanized steel base, two roof vents, five-year warranty. Listed at $3,231 on sale from $3,499 and waitlisted; Costco carries it online with a 15 to 20 business day delivery. No cresting, no glass, no steep pitch.
Which Buyer Should Get Which
Under $12,000 and you will manage the base yourself. Janssens Royal Victorian VI 23 or VI 34. Budget the knee wall, the drop-door kit, hinged doors, freight inspection and a weekend or two of assembly on top.
Under $10,000 and the pitch matters more than headroom. Exaco Junior Victorian, with the 5 ft 2 in eave understood.
$20,000 to $35,000 and you want wood, or narrow panes. Sturdi-Built for redwood, Gothic Arch for the pane width.
$40,000 and up and you want it designed, delivered and built. Hartley or Alitex. Get the wall drawings, the installation scope and the warranty in the same document, and compare them with the residential builder shortlist before signing.

Frequently Asked Questions
Can anyone speak to if they think Hartley is worth the huge cost difference compared to a like sized Janssen brand greenhouse?
The difference buys three things you can name: a 30-year guarantee against a dealer-quoted 15, a crew that installs it, and drawings your builder works from. It does not buy thicker glass; both are 4mm toughened. Whether that is worth three to five times the price depends on whether you would otherwise pay a contractor to do the base and assembly anyway.
My dream greenhouse, I wonder how much it would cost to build something like this?
If the picture is a tall glass house with a crested ridge on a brick wall, the kit alone is $9,799 to $13,999 from Janssens today, plus the wall, foundation, doors and assembly. Delivered and installed by Hartley or Alitex, the same picture starts around $30,000 and commonly runs far past it.
Does anyone have any experience with these? (Janssens)
Owners in the Janssens review report assembly running from two days to ten working days, glass excluded from the warranty, and a delivery inspection that decides whether cracked panes are the freight carrier's problem or yours. The structure itself draws few complaints once it is up.
I would love an Alitex greenhouse, but since I'm not made of gold, I will build it myself.
The realistic self-build route to the Alitex look is a Janssens Royal Victorian on a masonry knee wall with the drop-door kit and hinged doors, in fir green. It will not have Alitex's ornament or its installation crew, and it will cost about a sixth as much.
Has anyone done a comparison of these two Victorian structures and if so what does MSU or anyone else consider the better of the two?
No extension service rates one Victorian brand over another, and neither do we without a physical test. What can be compared on paper is in the table above: pitch, sidewall height, glass thickness, what is included, and the price at the same footprint.
These guides are built from manufacturer documentation, public specifications, primary research where health claims matter, and repeated buyer questions that show up in real ownership and installation decisions.
Manufacturer responses can clarify pricing bands, warranty terms, support footprint, or common mistakes. They do not move a page up the shortlist on their own.
