Round-log Frame House

Such style is unfortunately very rarely used in Russia due to the fact that a only few architects are capable of designing the frame structure of the first floor.

This is a clear Canadian style described by combined application of round log and frame structure: outside walls and part of the walls of ground floor are built of round log whether the first floor is a frame structure.

Main advantage is a more effective use of inner space, no shrinkage of the first floor, large rafting beams made of round log. Application of Underscribe (gap in the notch) and Overscribe (gap in the butts) allows to predict the behavior of timber house within shrinkage.

As a rule, such houses are built of large diameter logs that gives them specific nice look and solidity. We mostly build such houses for Germany and Austria where this technology is mostly evaluated and appreciated these days.

You can either order only log shell with assembly on your foundation or whole house on turn-key conditions.
