A light and airy, stylish workshop, loads of space for working and storage. The Mammoth is a high quality, hand made workshop and every feature sets the building apart from others.

The framing is a mighty 3" x 2" square, significantly larger than even our standard framing giving the building immense strength.

The modular design means you can swap the window, door and plain panels with each other so you can have the layout you want. The doors and window frame are pre-hung for easier assembly. The high grade 12mm T&G log cladding provides much improved weather proofing and longevity.

The internal working height is over 6 feet at the eaves providing a really comfortable working environment for the vast majority; again this is significantly higher than many of the cheaper sheds.  Both roof and floor are of tongued and grooved pine.

The 16 mm floor is included on 70x44 mm joists. The opening windows are storm resistant, traditional joinery quality frames glazed with 3mm glass.  All of the timber is sourced only from very slow grown, high grade, FSC approved, European pine. Green mineral felt is also provided.

The building is treated with a basecoat treatment ready for top coating by you immediately after installation.  (Imperial dimensions are approximate to the nearest foot, please refer to the exact metric dimensions in the data given).

Allowance should be made for the roof overhang and for access around the outside during construction and subsequent treatment.


  • 12mm Tongue & groove shiplap exterior cladding
  • Constructed using robust 44x70mm super-heavy framing
  • Upgraded 16mm extra-thick tongue & groove flooring
  • Joinery double doors with storm-proof profile and quality lock, handle and keys
  • Multiple opening windows
  • Heavy-duty green mineralized roofing felt
