Eos Royal T

A crown jewel in your garden with unmistakable presence

Ready to give your garden a truly royal finish? The Eos Royal T is Janssens’ statement model: a T-shaped greenhouse that combines the timeless roofline of the Eos with a stately front bay and double hinged doors. Functional enough for the serious grower, stunning enough to elevate any garden instantly.

This greenhouse adds the character of a garden pavilion to the classic Eos. The Royal T is immediately recognisable by its high ridge, projecting front bay and double doors. A versatile space you’ll use year-round, as a workspace, growing space or simply as an atmospheric garden room.

Endless combinations

Our Eos Royal T is fully modular and customisable

Every Eos Royal T is unique, because you give it its final form. You choose the length that suits your garden and the colour that complements your home or planting. For the configuration type, you can opt for a freestanding unit, a lean-to against the wall or a wall-mounted installation on top of a dwarf wall. The glazing is in toughened safety glass, and you decide on the position of side windows/top-hung windows, roof windows and ventilation elements yourself. Finally, there are the decorative finishing touches: from elegant ridge ornaments to decorative panels that lend the Royal T its regal character.

This way, the Eos Royal T adapts effortlessly to your garden, style and sense of distinction.
Explore the different options below and create a greenhouse that is perfectly yours.

Freestanding

The Eos Royal T is a detached T-shaped greenhouse that can be placed completely independently of your home. Ideal as additional living space, a studio or a relaxation area in the heart of the garden.

Wall-mounted

The Eos Royal T can be mounted on a dwarf wall of 20 or 40 cm, giving the greenhouse an even more exclusive appearance, ideal when used as a garden room.

The crown jewel of your garden

The projecting front bay gives the Royal T far more than visual impact, it creates a natural entrance zone with double hinged doors where you step in easily, arms full of plants or heading to your favourite spot inside. The interior feels more spacious than the dimensions suggest, and from the outside, it is a greenhouse that instantly adds character to any garden.

How long does an Eos Royal T actually last?

A T-shape is technically more demanding, and that is precisely where Janssens makes the difference. The reinforced connections between the main volume and the front bay are engineered to absorb decades of structural load, the seals remain watertight even at the junctions, and the aluminium never needs painting or treatment. A spectacular structure that will hold its allure twenty, thirty years from now.

What makes a Janssens unique

A Janssens can be recognized by three things: the choice of materials that last for decades, a range that adapts to every garden instead of the other way around, and a level of finish that convinces even the most demanding gardener. These three pillars form the foundation of every model.

Durability

Materials and design focused on weather resistance, ease of maintenance, and timeless design. You buy a Janssens once.

Wide range & custom-made

From 'action models' (ready-made standard models) to fully customizable greenhouses, with a choice of dimensions, doors, windows, glazing, and finishes.

Top-quality materials

Maintenance-free aluminium, safety glass, durable rubber seals, and stainless steel fasteners. Every component is chosen for the long term.
