what is tongue and groove cladding

A bespoke shed from Superior Sheds Swansea Ltd (South Wales) allows you complete customisation from style, size and ironmongery to treatment, windows and security options. Bespoke, made to measure sheds and outdoor buildings such as garden offices are our specialities. We have a great deal of experience of understanding our customers’ requirements.

Garden sheds are no longer just a storage place for tools or garden chairs. If yours is your workshop or garden office, chances are you have expensive pieces of equipment you want to protect. This is the reason we offer a variety of security measures such as alarm systems, padlocks, and windows that can be installed with security mesh. Check out our useful blog post on our top shed security tips here.

Garden Sheds South Wales - PEFC

All of our timber comes from FSC or PEFC certified suppliers

It if for this important reason that we buy all of our timber products from sustainable plantations that are replanted after they have been harvested.
