Prefab Housing "Frankfurt" 267 m² / 2874 ft²

1) Blueprints and other documentation

• Preliminary architectural drawings (NOT STAMPED).
• Shop structural drawings (NOT STAMPED). If required by local building authorities, review by a state-licensed professional is to be done at additional cost.
• Easy to read Assembly Manual.

2) Wall set

• Sill plate board to (larch wood) to put it under the walls and protect the wall beams from moisture - 2” х 7,9” (50x200 mm) - (for slab type foundation - highly recommended option)
• Strapping beam (with pile foundation) (at least 5.9”x5.9” (150х150 mm) - may be thicker depending on the project)
• Log wall system: first grade white pine (free of knots and wood defects, for increased durability of the beam) Stable engineered wood – GLT. interlocking profiled Logs with cups according to the house project.
• The logs are presented in 3 sizes in width and 2 in height - as illustrated in the gallery above.

Available Log Width - 6,4”; 7 7/8”; 9,45”; (160; 204; 240 mm) - price is given for 6,4” (160 mm) thickness option. 7 7/8” (204 mm) - optimal solution for year-round living in the middle climatic zone, in terms of the ratio of cost and energy efficiency. 9,45” - is for the most frosty and windy regions, like north of Canada or Syberia. No additional wall insulation needed for all options.

Available Log Height - 7 3/32"; 10 5/8”; (185; 270 mm) - price is given for 7 3/32" (185 mm) height option. Higher logs are used in bigger houses, where the larger size of the log correlates more with the scale of the building.

The U-value for the calculated beam wall is 0,585. It means, that 7 7/8” (200 mm) thick laminated timber wall is equivalent to an 31,5” (80 cm) brick wall)

Cutting of material according to the project design, with the cutting of the end grooves, with protective finishing of the ends, ready to paint. Sanitized and kiln-dried, pre-cut corner joinery system, pre-cut spline notches, pre-cut window and door openings (*minor trimming and odd-shaped openings may need to be cut on-site). Log wall erection diagrams included. Log bundles are well factory wrapped from six sides.

Internal walls are made in a framed design - to reduce the final cost and the possibility of various interior finishes. The use of beams for interior walls is an option, and is available at an additional cost. In this case internal finishing won’t be needed - which is lowering final cost and speeds up moving in.

• An intertwined seal for corner joints
• Laminated beams structural posts - 8” х 8” (200x200 mm) - where required by project.
• The casing frame for window and door installation is 1.6" x 2" (40x50 mm) dry planed block. It is installed inside the window opening, so that the shrinkage of the house after assembly does not change the size of the opening where the window is installed.
