Severn 400    Log Cabin plan layouts
Severn MKII Log Cabin plan

Ah, the Severn®, our Flagship (not a real ship) Log Cabin, the bee's knees, the big cheese, the large cabbage, I think I've lost the plot! A Severn® will satisfy your every demand, for example if you want to go to the moon it can take you. Recipe for Severn® to take you to the moon: A. Go on intensive astronaut course with a few mates. B. Add rocket ship. C. Insert lots and lots of rocket fuel. D. Remove Severn®. E. Simmer gently until blast off!

And in the words of my wise father, "stop talking rubbish son and talk about the product!"

The MKII edition Severn® 400 Log cabin is a fantastic addition to any home, adding plenty of extra space to your living area. There's enough room inside to create a spacious garden office or games room for all the family to enjoy. Provide yourself with the ideal outdoor building for hosting garden parties and entertaining guests, or somewhere for you to just quietly relax.

The Severn® 400 Log Cabin Kit is supplied with a French door and two opening windows for easy access when moving items in and out of the cabin, and to let in lots of natural light. Additional windows and doors are available to create a brighter log cabin with added ventilation.

Add the optional 1.5m decking to create an ideal area for relaxing out in the sun or under the shade of the log cabin's canopy.

Take a look at the story of how our log cabins are manufactured.

For your Log Cabin we recommend a solid concrete base to footprint size plus 100mm all the way round, for example:

  • A Rhine® 4m x 3m would need a base approximately 4200mm wide x 3200mm deep.
  • For a Rhine® 4m x 3m plus 1.5m decking the base would need to be approximately 4200mm wide x 4700mm deep.
  • For a 9m x 3m Tamar® Grande the base would need to be approximately 9200mm wide x 3200mm deep.
  • These sizes are the minimum sized base needed for these particular cabins.

Standard Severn® 400 Specification:
