The Gowers favorite heavy duty premium shed builder

Providing the Gower with Sheds that are built to last

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.

12x8 standard height with extra windows

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.
