Terrafirma Grand Duo by ShadeArt


An especially elegant, strong, durable, and larger side post parasol with two canopies from one mast of natural timbers and stainless, or all stainless.


Designed and manufactured in the United Kingdom by ShadeArt, the Terrafirma Grand Duoside post parasols or umbrellas, meet the highest quality and style standards and are suitable for both residential and commercial installations. The unique fusion of laminated timber and aluminium masts with stainless steel booms or all stainless mast and booms, makes for an especially elegant, strong, and durable piece of highly functional outdoor furniture. Terrafirma parasols and umbrellas can provide year-round shade and rain protection as well as adding colour and design flair to your outdoor setting.


Terrafirma Grand Duouses either the Terrafirma Single mast (93mm by 93 mm) or the heavy-duty Grand mast (141mm by 141mm), depending on your environment and canopy size. The Duo supports two canopies from one Central or Lateral (side) mast and therefore provides even greater areas of unfettered cover – up to 8 metres by 4 metres. This flexible design can also be configured as a Quad with four canopies - Terrafirma Grand Quad


Available in a wide selection of colours, sizes, shapes, and canopy styles, with optional heating, light, sound, and branding, the Terrafirma Grand Duo can be installed either permanently or to a pedestal base.

Easy for the customer to assemble and operate, requiring minimal maintenance and especially durable. With proper care and maintenance, this beautiful parasol will outlast any similar umbrella available on the world market today.
