Belgian craftsmanship
– since 1946
For 80 years, we at Janssens have been crafting multifunctional garden rooms where timeless elegance and technical perfection come together. A Janssens greenhouse is a space for relaxation, creativity and pure quality of life, built to last for generations...
Three generations of craftsmanship
What began in 1946 as a local joinery workshop in Lier has grown into an internationally recognised brand of quality greenhouses, cherished in the furthest corners of Europe and North America. For three generations, we have passed down our expertise. We have remained fundamentally true to our traditions while always embracing progress. The balance between craftsmanship and the latest techniques is where our strength and our DNA lie.
Greenhouses built to last for generations
At Janssens, our goal is simple: to provide every customer with a durable, stylish greenhouse that integrates seamlessly with their garden and home, connecting life inside and outside. From the first sketch to the last profile, we strive for timeless elegance and technical perfection.
Sustainability
Our greenhouses are designed for the long term. We work with maintenance-free aluminium, powder coating and durable rubber seals. 90% of our waste is recyclable. A Janssens greenhouse is not only beautiful, it is built to stand for multiple generations.
Wide range & made to measure
From our popular Action Models, ready-to-order configurations in fixed sizes, to fully customisable Custom Models with free choice of dimensions, colour, doors, windows and accessories. The right greenhouse for every garden and every budget.
Premium quality materials
We work exclusively with the finest materials: maintenance-free aluminium in slender yet ultra-strong hollow profiles, 4 mm toughened safety glass, durable rubber seals and stainless steel fixings. CE certified (EN 1090-1 to EN 1090-3), issued by TÜV Rheinland. Built to be trusted.

We plant a tree for every greenhouse sold!
Every greenhouse we make helps not only your garden grow, but the world too.
