Janssens Modern Greenhouse
Contemporary Design. Spacious Growing. Year-Round Garden Living.
The Janssens Modern Greenhouse collection combines sleek architectural styling with professional-grade greenhouse construction, creating a refined outdoor structure that functions equally well as a productive growing environment or a modern backyard retreat. Available in multiple spacious sizes including the M23, M34, and M36 models, this collection is designed for homeowners who want more than a traditional greenhouse.
Defined by its elegant sloping mono-pitch roof design, the Janssens Modern Greenhouse delivers a clean contemporary aesthetic that integrates beautifully into modern homes, villas, and landscaped gardens. The taller structure creates exceptional headroom and an open, airy interior feel, making it ideal for combining a dedicated planting area with a lounge space, garden room, or relaxing outdoor living environment.
Built with premium Janssens aluminum profiles and 4mm tempered safety glass, each greenhouse is engineered for long-term durability, strength, and reliable year-round performance. The thicker aluminum framing provides superior structural integrity compared to many standard greenhouse systems in this category, while tightly fitted glazing, rubber seals, and sealed window systems help improve insulation and climate control.
Designed for both functionality and comfort, the Janssens Modern Greenhouse includes automatic roof ventilation and louvre window systems that help regulate airflow and temperature with minimal effort. Double hinged doors offer convenient access while enhancing the greenhouse’s spacious, welcoming feel.
Whether you are cultivating exotic plants, starting a productive home garden, or creating a sophisticated outdoor garden room, the Janssens Modern Greenhouse collection offers a premium balance of modern architecture, practical growing performance, and lasting investment value.
