Our Story

At Superior Sheds Swansea Ltd we specialise in planning, building and installing pressure treated garden sheds.

Superior Sheds was born when we saw a gap in the market for high quality pressure treated garden buildings that are built to last decades not just a couple of years. Many people get hooked by the cheap price of online sheds, only to be servery disappointed when a pile of thin untreated wood turns up on their doorstep for them to assemble themselves.

We offer a full design, build, delivery and installation package on all of our garden buildings. Just place your order, sit back and relax whilst we do all of the work.

Our Products

All of our sheds and garden buildings are built using pressure treated 20mm thick, redwood cladding and structurally graded pressure treated 45mm X 45mm (2×2) framing timbers.

Our floors and roofs are constructed from pressure treated joists and fully exterior grade hardwood plywood for extreme longevity.

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.

Each timber garden building and piece of furniture we create is built to order to the specifications that suit your needs.

Looking around other companies we, struggled to find good quality and service, for an affordable price to suit style & budget. Gavin was very easy to deal with, very patient considering he was so busy he went over and above to get our shed made in time... Excellent service, very good quality and would definitely be using Superior sheds again.

Got in touch with the lads from superior as I was just getting in to woodworking and wanted a suitable workshop shed for the garden. Gav came to measure up and gave me a quote that I was very happy with so we went ahead. I must say that the build quality is great!

Would highly recommend this company very professional and a very high standard of materials used to build a hot tub shelter and corner bar for my garden. All of the staff were very polite and always on time. All my family and friends are very pleased with the work carried out and cant believe the change in my garden. I will definitely be using this company again and would advise anyone looking to have work carried out to use superior sheds you wont be disappointed
