RECENT HOME ADDITION PROJECTS IN HAMILTON, ONTARIO

Engineered Second Storey Addition

This project features a full second storey addition built on an existing bungalow, requiring complete roof removal and structural rebuilding. The new level was framed using engineered methods to ensure proper load transfer through the existing home.

Every stage was completed in compliance with Ontario Building Code standards, with a strong focus on structural accuracy, layout precision, and long-term performance. Openings and elevations were carefully planned to align with final design, maximizing both function and natural light.

Key Highlights:

  • Full roof removal and rebuild
  • Engineered framing system
  • Structural integration with existing home
  • Code-compliant construction

Crane-Assisted Second Storey Addition (Aerial Build)

This stage showcases a crane-assisted second storey addition, where large structural components were installed with precision in a tight residential environment. Prefabricated roof trusses and framing sections were lifted and placed to exact specifications, allowing for faster assembly while maintaining strict quality control.

From the aerial perspective, the complexity of the layout is clear—interior wall systems, load paths, and roof geometry are all executed in alignment with engineered drawings. This approach reduces on-site handling, improves efficiency, and ensures consistent structural accuracy across the build.

Projects like this require detailed planning, experienced crew coordination, and a strong understanding of structural sequencing to safely and efficiently execute each phase.

Key Highlights:

  • Crane-assisted installation of structural components
  • Precision placement of roof trusses
  • Efficient sequencing in a confined site
  • Engineered framing alignment and execution
