Ribboned Facade
+
Complex Curvature
A facade based upon a series of articulated ribbons was used as a point of departure because there were no local precedents where a similar approach had been attempted.

• Ribbon segment size reduced. • Segments are ‘stretched’ between frame members.
Lightning Laser Cutting
Use 300 - 350 x 1mm ribbon segments. Use stainless steel or aluminium. Fabrication cost = 2 - 3 times material costs. Unable to produce doubly curved surfaces. Local manufacturers are looking more towards architectural screens
RIBBONS WILL PERFORM BETTER IF PLACED UNDER TENSION JOHN

Anticipate human error. Use 3D hollow profiles for ribbons. All pieces should fit together like origami. The profiles of the blade would be supplied ‘loose’ then twisted over a frame to produce the bend.
ADJUSTMENTS • Curved hollow ribbons are implemented. • Number of elements are reduced to minimise cost and reduce weight. • Topologic relationship is established between ribbons to allow standardised fabrication.

Place/Memory EXPOSED TO
FEEDBACK
ADJUSTMENTS
Adrian Stanic
• How could the way the ribbons are used adapt as the functions change throughout the building? • Represent the heterogeneous nature of modern life. • Memories and the stories that construct a place are highly important.
• Ribbons mimic local graffiti and Victorian ornament.

Construction Logic EXPOSED TO
FEEDBACK
ADJUSTMENTS
Stanislav Roudavski
• Introduce some type of construction logic that governs how the ribbons are arranged. • Consider natural systems, webs, roots etc.
• The catenary deflection of the ribbons was simulated and used to inform the facade arrangement.

• Consider spanner swing radius • There needs to be room for adjustment/error in prefabricated components • Consider polypropylene or an organic plastic as a material.
• Parametric detailing was used to detect possible complications in the construction process.

Structural Assessment EXPOSED TO
FEEDBACK
ADJUSTMENTS
Jon Anderson
• Assessing structural members individually removes the need for over engineering. • Complex projects will become viable when architects can state confidently how much more than a standard approach geometrically complex solutions will cost. • Massive time savings are possible by using visualization models for structural evaluation.
• Structural members were bunched to minimize ribbon deflection. • Steel profiles were assigned to structural elements.

Attractor Point
FEEDBACK
ADJUSTMENTS
• Introducing random errors can cause a break in a close system. Break the ribbon. • Ribbons must add a new dimension to the project if they are to be justified - something that is unachievable through any other means.
• Certain ribbons are allowed to ‘break’ or loose connection during the catenary simulation. They dictate how the facade panels are divided. • Vertical circulation is moved against the facade. • Ribbons tuned to allow visual connections between certain locations.
