A net-house is a wind-loaded structure, not simply posts covered with fabric. Its safety depends on the complete load path from the net and roof cables through bracing, columns, anchors and foundations into the ground.
Design from site wind and soil
Confirm location, exposure, nearby obstructions, dimensions, clear height, door openings and soil capacity before fixing the structural grid. Perimeter, corner and door zones experience different loads from protected internal columns and should not be detailed identically.
- Site wind exposure
- Column grid and clear height
- Soil and anchoring method
- Openings and perimeter conditions
Create a continuous load path
Roof cables distribute fabric loads, while diagonal corner and façade bracing stabilise the frame. Connections, cable clips, turnbuckles, anchor projections and corrosion protection must be specified as carefully as the main columns; the weakest connection can govern the structure.
Net choice and maintenance affect loads
Smaller openings and blocked or dirty fabric increase wind pressure. Specify porosity, UV resistance, fixing details and controlled release or removal procedures where the engineered design requires them. Retension cables and inspect corners, doors, foundations and damaged net after significant weather events.
