Modern Pent Roof Glass Greenhouse by Janssens — Clean Lines, 360° Views
If your home leans modern and a classic Victorian glasshouse feels like the wrong fit, this is the Janssens greenhouse built for you. The sloped pent roof and clean black lines pair naturally with contemporary architecture — and with glass on nearly every side, you get a 360° view of your garden instead of feeling boxed in.
It's not just for growing. The Modern sets up just as easily as a garden room, pool house or year-round lounge, and since doors and windows can be installed in nearly any position, you can configure it to fit your yard rather than the other way around.

Available in three sizes from 79 to 200 sq. ft. (M23, M34 and M36), all with 6'8" sidewalls and up to a 9'7" peak — see the Sizes and Specifications tab for full dimensions, doors and windows. Every size includes a set of double-hinged doors, roof vents with automatic openers, push-out side windows, automatic louvre window(s), gutters with downspouts on both sides, and a 4" foundation frame. Custom sizes and colors are available as special orders.
Built for Strength
-
Heavy-duty aluminum frame — larger, thicker and stronger profiles than most greenhouses in its price range.
-
4mm tempered safety glass (where many brands use 3mm), TUV and GS tested for resilience to wind and hail.
-
Heavy-duty rubber seals hold every pane in place all the way around, for a tight, better-insulated structure.
-
Stainless steel hardware that won't rust or corrode.
- Rated for winds up to 120 mph and a 25 PSF ground snow load.
-
Full-height single glass panes — no overlapping panels, so it looks cleaner and won't collect dirt.
-
Foundation frame included, where other brands usually charge extra.

FAQ
Can I use it as a garden room or pool house?
Yes — that's one of the most popular uses. A mini-split or window unit can be installed for heating and cooling. For a fully insulated, double-paned garden room, see the LIVINGTEN.
What foundation do I need?
A level, solid base such as a concrete slab, pavers on a compacted base, or a knee wall. The foundation frame is included; we'll help you plan the right base for your site.
How does delivery and installation work?
Shipping is free by freight. Most owners assemble it over a few days with two people, or we'll coordinate an installer for you.
Can I finance it?
Yes — financing is available, and we'll try our best to beat any legitimate competitor price. Text us for our best price on your size.
Do I need a permit?
Often, since this is a permanent structure on a foundation — check with your local building department before you order.
