The Unopiù lean-to orangery combines the elegance of historic castle gardens with modern material technology – as a lean-to greenhouse directly on your house wall.
Designed in a classic country house style, the lean-to orangery blends harmoniously into any garden. The graphite grey iron frame gives it a timeless, noble appearance reminiscent of the grand orangeries of European manor houses. The transparent panels flood the interior with natural light, creating a Mediterranean atmosphere where plants can thrive all year round.
The frame is made of galvanized iron, powder-coated in graphite grey – robust, weather-resistant, and low-maintenance. The 6 mm thick UV-stabilized polycarbonate roof reliably insulates against cold and heat, while the 3 mm polycarbonate side panels offer maximum transparency and stability. All connecting screws are made of stainless steel, making them permanently corrosion-resistant.
The lean-to orangery is available in three widths: 215 × 154 × 223 cm, 285 × 154 × 223 cm, and 355 × 154 × 223 cm (W × D × H). The door hinge can be on the left or right, and there is a choice of 1 or 2 windows with pivot opening – allowing the greenhouse to be optimally adapted to your house wall and space requirements.
As a lean-to greenhouse, the lean-to orangery utilizes the warmth of the house wall and is ideal as a plant house for herbs, vegetables, and Mediterranean plants, as well as an elegant conservatory extension.

Frequently Asked Questions about the Unopiù Lean-to Orangery
How durable is the iron frame of the lean-to orangery?
The frame is made of hot-dip galvanized iron and is additionally powder-coated – a double protection against rust and weathering, ensuring many years of enjoyment with minimal maintenance.
Why polycarbonate instead of glass?
Polycarbonate is more shatterproof, significantly lighter, and, thanks to the 6 mm hollow chamber thickness in the roof, offers measurably better thermal insulation than plain glass – ideal for year-round use as a greenhouse.
Can I assemble the lean-to orangery myself?
The orangery is delivered as a kit and can be assembled with some manual skill. However, we recommend assembly by two people; upon request, we can arrange an assembly partner for you.
Which plants are particularly suitable for the lean-to orangery?
Thanks to the ample light and thermal insulation, Mediterranean plants such as citrus trees, oleanders, and figs thrive, as do herbs, tomatoes, or propagated plants, all year round.
