Timber logs

A bold, architectural presence.

Timber logs, with their squared profile and clean lines, enhance the sense of space, openness and natural beauty. If you love the look of a mountain lodge or a modern rustic home, squared logs give a structured, grand aesthetic with strong visual depth.

The standard finish is hand hewn. It pairs naturally with heavy timber framing in great rooms and dormers.

The wall is the part you choose. Everything that holds it together, keeps the weather out and carries the roof is the same whichever profile you pick: see what is in a package.

Cross-sections of the 8x10 timber log, channel style, alone and two stacked: a squared log with a tongue on top and a groove beneath, with the matching exterior and interior sidings.

What it looks like

Corners for the timber log

Available corner styles for this profile.

  • The dovetailed corner of a hand hewn timber log wall: squared timbers stacked course on course, their ends cut square and stepping out and in where each one locks over the timber below, with the sizes written on white labels on the ends.Click to enlarge
    Standard Dovetail Corner
  • The corner of a squared timber wall built against a square timber post: the flat, lightly hewn wall timbers run in from both sides and stop against the post, which rises from a plywood deck.Click to enlarge

The finish, close up

Hand hewn.

  • Close on the outside face of a timber log wall, unstained: each squared course hewn across its face in short scalloped strokes, with a few small knots and a narrow joint between the timbers.Click to enlarge
    Hand Hewn, Outside Face (wall log and exterior siding)
  • Close on a hand hewn interior wall in warm honey tones: flat courses scalloped across their faces by the hewing tool, dark knots scattered along the grain, and a fine joint line between each course.Click to enlarge

Every timber log section we mill

The mill’s own drawings, to scale, with the dimensions on them. Overall is the whole section, tongue to groove; stack is what one course shows on a finished wall, and what you multiply by the number of courses.

How many lineal feet will it take?

Square feet of wall into lineal feet of material, on the mill's own coverage figures. It opens on the 6×10 and lists this profile's products first, but every wall log and siding we carry a coverage figure for is in there.

The area you actually want covered, with windows and doors already taken out. Nothing here deducts them for you.

The answer will be here

Two figures: the bare conversion, and the same with the 15 percent waste allowance Sierra prices packages at. Pick a product and type the square footage.

What the number assumesfour things
  • Coverage is the mill's own figure for each product: the face left showing once it is installed, not the nominal size it is called.
  • The bare conversion is area divided by coverage. It assumes every foot of material lands on the wall, which no job ever does.
  • The quoted figure adds fifteen percent for waste and rounds up to a whole foot, which is the allowance Sierra prices packages with. It is not a rule for every job: a wall full of openings wastes more, a plain gable less.
  • Nothing here is rounded to a purchasable length, and there is no minimum order in this arithmetic. What lengths the mill runs, and what a load looks like, are part of a quote.
