The Portland Flatiron building is a timber framed mixed use building sited at the edge of a sloping triangular site in N Portland. The five floor plates will be open loft space of approximately 5,000sf each framed with timber columns and beams, and cross laminated timber floors with concrete topping slabs. The unique triangular geometry and the significant grade change across the site generated the simple diagram of lacing 3 formally independent elevations together, resulting in a weave of bay windows and open space at the corners. Cross laminated timber decking was chosen for its unique ability to simplify the corner geometries structural requirements.
