Rutland County Garden Furniture make great pergolas. We could leave the description at this but you may leave the site and never come back and we can't have that can we?
 
This Double Premium Wood Pergola in Rustic Brown is strong, stable and will be the centerpiece of your garden. It provides a perfect covering for a full table and chairs and is perfect for entertaining. The wood is high-quality pressure treated Northern European Redwood. We don't know what this means but it sounds strong and durable
 
These products are made in the UK and the images are shot in Rutland's HQ.
