Log Cabins.
Structural engineering for timber-frame
and solid log construction.
Where timber meets
precision engineering.
Log cabin and timber-frame structures demand a specialist understanding of wood as a structural material — its anisotropic behaviour, moisture-driven movement, joint mechanics, and long-term load redistribution.
At IGG, we combine Eurocode 5 timber design with advanced 3D structural modelling to deliver engineering documentation that satisfies both aesthetic vision and regulatory compliance. Whether you're building a single-storey alpine retreat or a multi-level log structure, we handle the full structural scope.

Timber isn't concrete.
It requires a different approach.
Settlement & Shrinkage
Solid log walls settle vertically as timber dries and compresses under load. Every structural connection must accommodate this movement without compromising the building envelope or transferring harmful forces to non-structural elements.
Anisotropic Behaviour
Wood behaves differently along and across the grain. Load paths, bearing lengths and connection designs must be carefully calibrated to avoid splitting, rolling shear failure or excessive deformation over time.
Moisture & Durability
Service class assignment, preservative treatment specifications and ventilated detailing are integral parts of the structural design — not afterthoughts. We ensure the structure performs at its design moisture content.
Lateral Stability
Log cabins require carefully designed lateral load-resisting systems. We analyse wind and seismic actions and detail the wall-to-foundation and wall-to-roof connections accordingly.
