Our Products

We only use our 20mm thick Scandinavian Redwood cladding for all of our garden sheds. Our many years in the industry has taught us that thinner timber claddings rot quicker. We want our sheds to be the best that they can be.

We believe by using the highest quality timber materials and preservatives available we can build you a shed or summerhouse that will last the length of time and that our team can be proud of.

We love building one off pieces of furniture and bespoke garden sheds. If you don’t see what you require on our website then get it touch, we are waiting to hear from you.

Great company to deal with! The boys came to measure up for an apex shed for us in Llanelli and brought samples of their cladding and framing wood. All looked very solid and the quote was competitive so we went ahead. Took them about 2 weeks to build then they came and installed it in a couple of hours. All in all a great experience from start to finish. 5*

We contacted Superior Sheds on behalf of my dad who lives in Llanelli. His old potting shed was in a mess so we decided to buy him a new one to surprise him with. After visiting a few local companies we decided to go with Superior as they were such nice chaps and gave us a very reasonable price that included delivery and installation. The build quality of the new potting shed is great and I must also highlight the fact that they went the extra mile and installed some free shelving.
Well happy and impressed with the quality and build. Thanks to Gavin and the boys for a job done well and professionally. I highly recommend superior sheds.
