About Us

XXL SHEDS® intelligent use of materials in our designs focus on what is the most suitable and efficient material that is fit for purpose in the structure.

Our XXL SHEDS® structures meet all certification standards, they are ‘fit for purpose’ and they are far more cost-effective than a traditional single material approach to designs and construction.

The secret starts with XXL SHEDS® design process. A XXL SHEDS® design begins with our Design Function Audit  – a comprehensive examination of the building’s purpose, the features of the property, the physical movements that will occur on site and any aesthetic requirements.

Then our Structural Engineers take the fully specified building and apply value engineering  principles to create a structural design that will be strong, secure, efficient and achieve certification.

We design and supply buildings to house agricultural and industrial facilities such as:

  • Warehouses and Factories
  • Industrial Buildings
  • Storage facilities
  • Transport, logistics and distribution centres
  • Truck parking and storage
  • Workshops
  • Horse stables
  • Aircraft hangers
  • Farm equipment sheds
  • Fertiliser and grain storage sheds
  • Hay storage sheds
  • Food production facilities
  • Equestrian riding arena
  • Packing sheds
  • School or sports roof covers
  • Waste transfer stations
