Rhine Log Cabin plan layouts

If you're looking for sleeping quarters, a winter retreat, heavy-duty storage or simply expert insulation then invest in the dual wall, your fiercest armour against the elements. It’s easy to see why two walls are better than one and the use of highly durable materials make this a very warm force to be reckoned with. So why not make a commitment to your garden building and let it know you'll always be around with the comfy, cosy, life is rosy, keep me toasty dual wall?

With 70mm of weather fighting, high density foil backed foam sheets sandwiched between its sturdy timber this modern solution will make you want to move in permanently. Designed to retain and reflect heat, with the highest quality insulation that's a bone-warming 50% better than polystyrene, the Dual Wall is King where cabin comfort's concerned.

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 veranda 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 Rhine 3 Grande Dual Wall Specification:

  • External Size - 4m (13'2") wide x 7m (23') deep (approx).
  • 2 Rooms - Room 1: 3.6m (11'10") wide x 2.6m (8'6") deep, Room 2: 3.6m (11'10") wide x 3.87m (13'1") deep (approx)
  • 130mm Insulated Walls - The dual wall log cabin has a 28mm external wall and a 28mm internal wall with 70mm polyurethane insulation between them. The insulation is foil backed to reflect and retain heat.
  • Floor - 19mm tongue and groove floor boards for a sturdy floor.
  • Roof - 19mm tongue and groove roof timbers to create a sturdy roof.
we don't use OSB sheet timber tongue and groove rooftongue and groove floor

 

Note: We only use tongue and groove timbers for our floor and roof not OSB sheet timber! (We only use MFP board on top of roof insulation, which will usually not be seen as it will have a roof covering over it).

  • Internal Eaves - 2040mm (6'7") (approx) High, the lowest point inside, giving plenty of interior space (this means you won't bang your head!)
  • Canopy - 1.1m (3'6") (approx.) deep canopy. Perfect for shade in the summer and cover from the elements in the winter.
  • French Door - Made with rebated door panels (for a more attractive appearance) and fitted with a secure lock.
  • Internal double door - To be cut in at your desired position along the dividing wall.
  • 3 Windows - Made with glass, not Perspex. We use glass as it is clearer and much easier to clean than clear plastic.
  • - DOUBLE GLAZING – Optional extra - * for improved Heat & Sound Insulation. ( see options below )
  • Floor Bearers - 70mm x 70mm Pressure treated floor bearers that sit underneath the log cabin to protect its foundations from damage by insects and fungal decay. Without pressure treated bearers moisture would damage the lower aspects of the cabin!
  • Roof Beams - Heavy duty 140mm x 45mm to prevent 'sagging'.
  • All wood is planed, pre-cut (with the exception of trims), and pre-notched for quick and easy construction. Click here to see how easy it is!
  • After simple assembly windows slot into place. Minor adjustments will have to be carried out on windows well within the scope of a competent DIYer.
  • French Door is provided in 6 assembled pieces that fit together then slot into place.
  • We supply you with all nails and screws needed for the assembly of your log cabin.
  • Look at our Testimonials!!!

Lifestyle Options:

  • Window can be positioned on either the left or right side of the Log Cabin.
  • Veranda - 1.5m deep (approx), consists of two banisters and pressure treated flooring and bearers.
  • Additional windows and doors are available.
  • Roof Shingles - Weather proof the roof of your log cabin with the addition of attractive roof shingles.
