Precision-Milled Log Kits — Built to Last
Every kit ships pre-cut, numbered, and ready to assemble. No special tools. No guesswork.
The InterStack Log System
Developed by Sawmill Structures in Ontario, Canada, the InterStack system eliminates the guesswork from log cabin building. Every component is engineered to fit — and only fit — exactly where it belongs.
70mm Nordic Spruce walls
Precision-milled from sustainably sourced Nordic Spruce — thick, dense, and built for extreme climates.
Double tongue & groove profile
Logs lock together with zero gaps. No chinking compound, no air infiltration.
CrossLock Corners
Proprietary corner system — no notching, no chinking required. Corners are strong, square, and weather-tight.
Individual ID numbering
Every piece is stamped with an assembly number. Building is like following a numbered puzzle.
