Modern

The sleek greenhouse for the contemporary gardener

Ready to give your garden a modern edge? The Modern is Janssens’ clean-lined statement piece: a greenhouse with straight lines, a low roof pitch and 204 cm side walls. Distinctive enough to stand out, understated enough to blend seamlessly into any contemporary garden.

This greenhouse is the contemporary answer to the classic. The low roof pitch and straight lines give the Modern its architectural look, while the high side walls create a light-filled interior, equally suited as a garden room, garden office, growing space or a spot for a hot tub or spa.

Endless combinations

Fully modular and customisable

Every Modern is unique, because you decide how it looks. You choose the dimensions that suit your garden, in widths of 236 or 310 cm and lengths up to 6 metres, and the RAL colour that matches your home or terrace. For the configuration type, you can opt for a freestanding unit or a wall-mounted installation on top of a dwarf wall. The glazing is in toughened safety glass, and you decide on the position and number of sliding or hinged doors, side windows/top-hung windows, roof windows and ventilation elements. To complete the look, you can emphasise the architectural character with additional narrow glass modules or decorative panels.

The Modern adapts effortlessly to your home, space and purpose.
Explore the different options below and create a greenhouse that is perfectly yours.

Freestanding

The Modern is a detached 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 Modern can be mounted on a dwarf wall of 20, 40 or 60 cm, giving the greenhouse an even more exclusive appearance, ideal when used as a garden room.

Why choose that sleek look?

The straight lines and low roof pitch not only create a contemporary appearance, they make the Modern exceptionally light-filled and give every square metre a feeling of spaciousness. Inside, you are bathed in light even in winter, and the minimalist design lets both plants and objects take centre stage. If you combine growing with garden living, this is the space for you.

How long does a Modern actually last?

Sleek architecture stands or falls with materials that hold their line. The Modern is finished in powder-coated aluminium that never rusts, never discolours and never needs repainting, and the profiles are precisely engineered to maintain their straightness for decades. A contemporary greenhouse that will look just as modern in fifteen years as it does on day one.

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.
