First Class Company

I have never been so impressed with a company ever before, in my 67 years on this planet! Not only is the garden furniture we received, nearly perfect in every way (only 1 screw missing), your prices & delivery service are great too. What makes your company so very special though, is your customer service back up. What an amazing team you have working for you!

Pergola review

I ordered a metal pergola with retracting sun screen. From looking up this item I found that this company had the right specifications of what I required. Delivery was very quick & within time frame specified. Communication throughout was excellent. It took a couple of weeks before we got around to erecting it. All the parts were labelled very well. The instructions given were very descriptive & simple to follow. All in all I am very pleased with this pergola it was a good price too. I would definitely use this company again & I would recommend them to others 😃 I ordered a metal pergola with retracting sun screen. From looking up this item I found that this company had...

Great Product

Great product. Robust. Looks fantastic. Really helpful customer service team who called me when I ordered to check the items as I’d accidentally added a different colour barge flashing compared to the profile roof sheets. Saved me a lot of hassle! Thank you. Great product. Robust. Looks fantastic. Really helpful customer service team who called me when I ordered to check the items... Great product. Robust.
