FORM & FUNCTION

What this form means

The tie-rod mushroom retains the curved two-wing beam, high at the centre and low at both ends, and adds exposed rods between the support and wings. It remains a side elevation; plan coverage, rod forces and anchorage need engineering design.

Rods and parking clearances

02

Rod-end anchorage and inspection

03

Umbrella canopy drainage

SITE FIT

Where it fits

Sites needing cover on both sides with a central column strip and adequate clearance around the rods.

DESIGN CHECKS

What to check in design

Check rods against doors, service equipment, lights and drainage. Both central and rod-end connections need access for inspection.

COMPARE OPTIONS

How it differs from neighbours

Visible rods and their connections distinguish it from a plain mushroom form; similar roofs do not imply the same fabrication list.

QUESTION & ANSWER

A common planning question

Are the visible rods decorative?

Do not assume so. Design documents should state their structural role, specification, connections and maintenance needs before pricing or building.
