Structure Details

This compact garage carries a steep 36° gable roof on engineered trusses, spanning the full 31m² (334 sq ft) footprint with no interior posts - space for one vehicle plus storage or workbench area. The 14 ft garage door sits in the long side wall, positioned near one corner. The steep pitch leaves a tall roof void above the ceiling tie for light storage - engineered as a roof structure, not a floored loft. The timber-frame construction with professionally engineered trusses ensures long-term durability and stability. Structural members are optimized for standard dimensional lumber availability.

What's Included

Complete structural engineering package created with licensed MiTek Pamir software:

 • Structural Drawings: Detailed elevations, floor plan, roof framing layout, and wall sections showing all timber members and connections
 • Load Calculations: Full engineering analysis for dead loads, live loads, snow loads, and wind loads
 • Production Drawings: Connector plate specifications and placement (where applicable to the design)
 • Cutting Bills: Exact dimensions and angles for every structural member - ready for cutting
 • Material Pick List: Complete timber quantities, fastener specifications, and hardware requirements
 • Foundation Layout: Perimeter and support structure details with anchor points
 • 3D Visualization: Interactive 3D model accessible via QR code for spatial understanding
 • Dual Measurements: Separate folders with metric (mm) and imperial (inches) versions

This plan provides everything needed for construction. All structural connections are engineered with proper load distribution using MiTek's professional timber engineering system.
