Pressure Treated Garden Buildings

If you’re looking for an outdoor garden storage solution that will provide long-term durability and guaranteed longevity, look no further than our pressure treated sheds. Garden sheds are treated with a special formula that allows them to withstand fungal decay and rot for more than 15 years. Pressure Treated Sheds will also save you money because you’ll never have to treat them again. Rain or shine, your pressure treated garden shed will stand up to the elements.

A huge fine selection of pressured treated sheds for your perusing pleasure. It doesn’t matter if you need a garden office, garden storage, or just a place to escape a passing rain shower, we have the perfect storage solution for you.

We have multiple styles for you to choose from, including various types of cladding and roof types. You can choose from shiplap sheds, overlap sheds, pent sheds and more. It’s all up to you. It’s your choice. It’s your shed.

How does pressure treatment work?

You’ll find that treated timber will outlast any number of wooden sheds you have owned in the past. The process of pressure treating wood involves impregnating the timber with a special wood preservative. This is done by placing the wood within a cylinder filled with the wood preservative. The end result is a hard-wearing pressure treated timber that’s used to construct amazingly durable sheds.

Extra strong construction

Project Timber sheds are extra durable due to our patented shiplap cladding as well as our easy and strong tongue and groove construction. Coupled with our 15-year anti-rot guarantee, you can rest assured that your shed will last you a very long time.

Invest in a pressure treated shed today

Pressure-treated sheds are the perfect addition to our long line of wooden garden sheds. They’re heavy-duty and have a multipurpose interior that makes them extra versatile. With a hard-wearing smooth wood finish, our pressure treated sheds are second to none!
