K3-Cottage: Professional 3D CAD Software for Log Home and Timber Frame Design
About K3-Cottage
K3-Cottage is a specialized software solution developed specifically for the design and engineering of homes made from round logs, profiled lumber, and double timber walls. It serves as a comprehensive tool to automate the entire design workflow, providing all necessary documentation for every stage of a home-building enterprise, from the architect’s desk to the production floor.
Core Capabilities
Versatile Wall Profiles
The software supports a wide range of wall profiles, including round logs, square timber, and saddle-notched logs (laftet).. You can freely define any wood species and profile dimensions.
Automatic corner joints
Complex corner joinery is fully automated. K3-Cottage intelligently detects wall intersections and generates precise joints based on your selected type. You have full control to select the joint type, including classic round notch, dovetail, Norwegian lock, «warm corner» (German cut), and more.
Support for Modern Building Technologies
In addition to classic solid wood construction, K3-Cottage supports advanced and energy-efficient building methods, including the «Wood Bricks» and «Double Wall» (double timber frame) systems.
From Design to Production: Automated Outputs
Complete Construction Documentation
Once your 3D model is complete, K3-Cottage automatically generates a full set of production and construction documents. This eliminates manual take offs and significantly reduces the risk of errors. Outputs include:
- Detailed cutting lists and drawings for each log or beam.
- Wall assembly charts and row-by-row installation plans.
- Floor plans, roof plans, elevations, and cross-sections.
- Material registers and cutout tables.
Direct CNC Machine Integration
Bridge the gap between design and manufacturing. K3-Cottage seamlessly exports data to CNC machinery. Our K3-Cottage CNC Module is compatible with leading CNC systems and production lines, including:
KRUESI CMI 4×4, STROMAB, SCHMIDLER, MAKRON, HUNDEGGER.
Designed by Users. Built for the World.
Every project starts with an idea — and K3-Cottage helps turn it into reality. Explore screenshots of beautiful log cabins and timber homes created and constructed by our global community of designers and builders.:
