Square Face Dovetailed Timber

Logs are band saw milled on the two vertical faces, and left naturally round at top and bottom. Logs may be hand hewn if desired. Log walls typically have a 1 to 2 inch space between them. However, the full scribe technique can be utilized the full length of the logs. Corners are joined with compound dovetail notches. A typical log would be 10 inches thick and 15 to 17 inches high at mid-span. Other details for this style include galvanized pipe rods and plywood blocking at openings and structural areas for stability, and a hidden sealer strip system at the notches.


  1. Between the compound angles of the notch and the rustic natural lines of the rounded sides of the logs, this is the answer for the more “timber-oriented” homeowner.
  2. This style lends itself well to timber style roof support systems.
  3. It is feasible for a homeowner or contractor to reassemble the log package themselves.
  4. The flattened faces of the log walls make it easier to finish the home.

5.Ackerman Handcrafted Log Homes believes this style is the perfect marriage of old word craftsmanship and new world technology. Each notch is planned on a CAD (computer aided drafting) program. Each notch has its own dimension. Then the layout is transferred onto the log for placement of our custom dovetail template jigs. The result is a handcrafted structure that has used new technology tools for efficiency of building.

  1. Depending on design, these log structures can usually be pre-assembled in a short period of time, and be ready for shipping.


  1. As with other styles, design is very important. Walls cannot be as long as in other styles due to the taper of the logs and the geometry of the compound dovetail notch.
  2. A decision must be made whether to allow the structure to settle or not. If the walls are full-scribed, the structure must be allowed to settle.
  3. Although the notches will be sealed with a hidden sealer strip system, the vertical shoulders of the notches will inevitably shrink and gap to some degree. This is not a problem, only a consideration.. This gap is typically chinked or caulked later.
  4. High quality, large diameter logs must be used to achieve the proper profile for the notches.
  5. The thermal performance of the log will be decreased by milling the two vertical faces.
