FORM & FUNCTION

What this form means

This form organizes central supports, two projecting roof wings and rods together. Unlike a one-sided tie-rod form, it serves parking on both sides; neither set of rods should conflict with doors, circulation or chargers.

01

Bay depths and cover on each side

02

Clearance under both rod systems

03

Central column and foundation strip

SITE FIT

Where it fits

Sites with a usable central support strip and sheltered bays on both sides while retaining open outer approaches.

DESIGN CHECKS

What to check in design

Check each wing’s reach, lowest rod positions and central foundations. If the sides differ, neither structure nor drainage can be copied unchanged.

COMPARE OPTIONS

How it differs from neighbours

Unlike the offset T form, this central support serves bays on both sides, with exposed rods and joints on both wings.

QUESTION & ANSWER

A common planning question

Can the form serve unequal numbers of bays on each side?

An asymmetric layout can be studied, but each wing, its foundation and runoff need separate checks rather than mirroring a standard unit.
