Retro Royal Victorian Greenhouse by Jenssens

Description

The Janssens Retro Royal Victorian is the definitive expression of Old-World greenhouse architecture — a structure that transforms any outdoor space into a timeless estate feature with the engineering integrity to match its historic ambition. Distinguished by its narrow 14-inch panes of 4mm tempered safety glass, decorative aluminum lower panels, and soaring 9’ peak height, the Retro Royal evokes the nostalgic character of a classic British conservatory while delivering the structural performance and climate control of a modern premium outdoor room. No other structure in the Janssens range makes a stronger design statement.

The decorative lower aluminum panels create a sense of privacy and enclosure that open-glass structures cannot achieve, giving the interior a warm, walled-garden quality that is ideal for intimate entertaining, private residential retreats, or hospitality environments where atmosphere is as important as architecture. Three available sizes — from 150 to 250 square feet — offer flexibility across residential and commercial applications, and every unit ships complete with a built-in misting system, gutters with downspouts, and a reinforced foundation frame.

Manufactured in Belgium by Janssens and backed by a 15-year limited warranty, the Retro Royal Victorian is a structure built not just for this season, but for the next generation of owners. A compatible shade curtain is available separately.

Why You’ll Love It

A Visual Masterpiece in Every Direction.

The narrow glass panes and decorative cresting create a play of light and shadow that changes throughout the day — a textured, high-design aesthetic that no wide-pane structure can replicate. From sunrise to dusk, the Retro Royal is the most visually compelling structure in the Janssens range.

The Privacy of a Walled Garden, the Light of Glass.

Decorative aluminum lower panels give the Retro Royal a sense of enclosure and warmth that open-glass structures simply can’t achieve. Guests and occupants feel contained and comfortable rather than exposed — the ideal atmosphere for intimate entertaining, private gatherings, or a residential sanctuary.

Four Seasons of Uncompromising Comfort.

Heavy-duty rubber seals and precision-fit glass panels provide exceptional insulation, maintaining a comfortable interior environment well into winter and through the heat of summer. The Retro Royal is a genuine year-round outdoor room, not a fair-weather feature.

Turnkey from the Day It Arrives.

Every Retro Royal ships complete with a built-in misting system, integrated gutters with downspouts, and a reinforced foundation frame — the kind of professional-grade inclusions that most structures charge extra for. Install it, furnish it, and use it.

A Legacy Investment.

At 9’ peak height with hydraulic-close double-hinged doors and lockable hardware, this is a structure that commands respect — and retains it. Backed by a 15-year Janssens warranty and built to TUV and GS safety standards, the Retro Royal Victorian is the kind of investment that appreciates over time.
