Our Plan of the Month: Vertical Log Cabin

This is our first vertical log construction project in over 30 years designing log homes!  While attending log home shows I did run into a couple of displays thru the years.  This is an owner build and it will be a year round home in Nova Scotia Bay of Fundy area.  Client already got the logs with diameters from 12” for corner posts to 8.5” average for vertical log fillers for walls.  The vertical logs are flattened at each sides to fit with next log using 1×4 spline board.  P-foam gasket is installed vertically at inside and outside contact line.  Chinking will be applied later to cover the widening vertical gap between logs as they dry and shrink in diameter.  A 2-2×6 top plate is used to lock the logs at top.
This design uses attic manufactured frame trusses to add a living space within roof for a master suite and sitting / music room.  This low budget log cabin is sitting on a well insulated concrete slab on grade.  Footprint is under 600 square feet with a 442 SF for second floor.  The attic trusses extend 4’ beyond log wall below to create a dry covered walkway patio around the cabin.
This is great weather protection for the main floor log work!
