How to build a shed or gazebo from scratch

Working out how to build a shed might seem like a big job, but it’s actually fairly straightforward. Start by choosing a good location, where you'll be able to access the structure from every side and be sure to check there are no young trees nearby, as the roots may disrupt the structure's position. This will allow you to easily maintain your structure and apply wood treatments in future. Make sure the area is fully prepared before laying your foundation.

Wooden Shed Base

A strong and level foundation is important to ensure the structure remains dry. There are three types of bases that may suit; we recommend concrete foundations for larger structures, but paving slabs are also an option. The third choice is a specially designed shed base, which removes the need for concrete and is best for less experience DIYers. Ideally, get a friend to help you build the structure. 

Take a look at the video below for a full step-by-step demonstration on how to build a shed:

Make sure you have the right tools to build a shed before you get started. You shouldn't need more than a few common hand tools for the job. If you do need any specialist tools, like a cement mixer, why not use our tool hire service?

Repairing an existing shed or gazebo

If your existing garden structure has seen better days, it may be time for a little maintenance. Ideally, any outdoor wooden structure should be treated with a water-resistant treatment once a year, both inside and out. Shed windows should also be checked periodically to ensure that the sealant is still intact, so no moisture can get in. The hinges of any doors and windows should be checked for rust and treated if needs be, and the base of your structure should also be examined to ensure it’s still stable. 

You should also thoroughly check the felt roof of your shed for rips or tears. If it's damaged, you'll need to strip it and lay new roofing felt. Take a look at our blog or watch the video below for more help with this:
