How to extend your steel shed the right way

There are two types of shed extensions: the ones that are meticulously planned for, and those that are tacked on at a later date.

If you’re building a shed and there’s a possibility you might need additional space in the future, it’s best to let us know in the early design stages.

When you design a shed that is engineered to handle an extension, the process is vastly easier (and cheaper) when you go to add the extension at a later date. On the other hand, if building owners fail to plan ahead, it can be a difficult and costly process to extend or alter your structure, due to the shed’s potential engineering limitations.

What does this mean in practice?

Let’s take a closer look at how to go about designing your shed the right way.

Planning ahead for shed extensions is the best way forward

A lot of clients approach us wanting to build their shed in stages. This is often easier on the bank balance plus it makes good commercial sense to design a building that can grow with your needs.

It’s a good idea to consider designing your structure so that it’s engineered to take an extension. This is a smart approach for most commercial projects, enabling the building to grow and change with your needs (or your tenants’ needs) in the future.

As an example, one of our current clients has a large block and wants to make the best use of the site. They are allowing for a future extension by building the shed as close to the front of the property as possible, then down the track, they can add onto the rear.

From a design point of view, we can take this plan into account and design the structure so that it can easily be added on to in the future.

How to extend your steel shed

If you need to extend your shed and weren’t able to pre-plan for the extra space in the early design stages, you can still get a good result depending on the size, shape and orientation of your shed and the available space on site.

Extending your shed from the gable end

Shed extensions work best from the gable end, so it’s wise to factor this into your design, including considering how your structure will be positioned on your land. Allowing additional space at the gable end means you can extend the shed relatively easily in the future.

Extending from the long side

It is also possible to extend from the long, non-gable side of your shed so that you end up with something like an ‘M’ shaped roof profile, having two gable ends sitting side by side. However, you’ll need to ensure you include box guttering between the old and new structures.

Getting the best result with guttering

A key thing to consider with any shed extension is making sure the guttering is adequate for the expanded roof space. If you’re looking to make an addition to an existing building that hasn’t been specifically designed for extension, the extension will have to be free-standing.

This means your guttering will join the existing building with a flashing, but the overall structure will stand on its own.

As mentioned above, box guttering is an option when you’re joining two roof lines together, to ensure you capture rainwater from the newly created valley in the roofline.

Design your shed for future growth and expansion

In summary, the best course of action if you haven’t already got a shed in place is to factor in any potential extensions into your initial designs. This will ensure you’re covered for future growth.

However, if you’ve outgrown your current shed and you need more room to run your business, there are often ways to extend your shed to create more space and keep the structural integrity intact.
