Looking firstly at the glossary of terms for building work that does not need a building consent there are a few under which the starburst could come under:

a hoarding (a structure alongside a public way providing side protection but no overhead protection). Also some componentry to be made out of a lightweight material (thin flexible fabric material, such and canvas, shade mesh or vinyl)

a pergola (exterior, decorative, open-frames structure often to support climbing or trailing parts)

playground equipment (structure with or on which children can play)

a plinth (a supporting base)

a sign perhaps ( a structure, including any structural support, for the purpose of conveying information or an instruction)

But overall the starburst need structural stability: The ability to withstand the combination of loads that a building can experience

In detail the many things that come under building work that does not need a building consent:

EXEMPTION FROM THE FOLLOWING

Repairs, maintenance and replacement guidance

Need to look at of fire-safety and durability material used and external moisture requirements for the starburst plus the coatings and paints to protect surface.

Drainage and plumping

N/A

Windows and doors in existing buildings

N/A

Improving access for people with disabilities

Placement by library already has a ramp where the wheel-chair bound can experience the starburst by tactile encounters. There is reference to contrasting surfaces outside the entrance way to a dwelling, The starburst could be placed on a flat but visually different surface.

Interior non-residential alterations

N/A

Internal floor and wall linings and finishes in dwellings

N/A

Network utility operator infrastructure

N/A

Signs

Starburst could come under being a sign: surface area should not exceed 6 square meters nor be greater than 3 meters above the ground, but the sign (starburst) needs to be designed by a chartered professional engineer! Also may have to get local council approval, is the architecture building a heritage/character building? It is in an urban area and there may be restrictions in the council’s district plan.

Retaining walls

N/A

Retaining walls in a rural zone

N/A

Internal walls

N/A

Walls, fences and hoardings

As a hoarding, the starburst cannot be taller than 2 meters above the supporting ground. However, when installing the starburst, there needs to be a 2.4 meter high hoarding around the construction site to ensure public safety.

Dams

N/A

Tents and marquees

Starburst will not be a temporary structure, so therefore cannot be considered a tent or marquee which can only be up for the maximum period of 1 month.

N/A

Private tent and marquees

These can only be up for the maximum period of 1 month.

N/A

Platforms/decks

Possibly placed on a deck like structure, where the ends could be fixed into the decking grooves for sturdy placement. No person to fall more than 1-1.5 meters even if it collapses. The deck to be smaller than 50cm above ground level no greater than 50 square meters, but if the deck is 1 meter above ground will have to have a safety barrier installed along both sides.

Plinths

Possibly useful for affixing the edges of the starburst to give it rigidity, but will need to be designed by a chartered professional engineer as it is a concrete mass.

N/A

Stalls

N/A

Temporary storage

N/A

Detached buildings

The starburst cannot be greater than 1 storey and exceed 10 meters in floor area, does not contain sanitary or cooking usage, but can house accommodation. People can sleep in the starburst!

Verandahs, patios, porches and awnings

This is to enclose a space that is existing and no greater than 5 square meters.

N/A

 Awnings

Attached to a building, from the ground floor and can’t be greater than 20 square meters in size. Needs to be weather tight

N/A

 Verandahs and porches

On the ground floor, is over a deck or patio, and can’t be greater than 15 square meters. Porches and verandahs are attached to a building, often to protect the face of a building and to provide shelter. Made from permanent materials.

N/A

Pergolas

These are low risk, framed unroofed structures and used as a garden feature. The starburst could be considered this? Size can be 26 square meters in total, but no higher than 2.4 meters and 3 meters wide.

Shade sails

Must be made from lightweight material and cannot exceed 50 square meters in size, not be 1 meters to any legal boundary and is on ground level. Wind loading has to be considered, In a public park  there is a limit of 12 meters in size if using a number in combination. So with the starburst the two have to be 12 meters in size each.

Carports

N/A

Installing thermal insulation in an exiting building

N/A

Penetrations with a maximum diameter of 30cm guidance

The cables used to affix the starburst down will need to be in holes no greater than 30cm.

Playground equipment

The playground equipment has to be designed by a chartered professional engineer.

N/A

Territorial authority discretionary exemptions guidance

No building consent is needed if the work carried out is done by people/company who has a track record with the council of doing this work. Uniservices should have this history. But, needs to be designed by a chartered professional engineer or registered architect (Judy!!!). Building done by a licensed builder. Starburst has to be with a floor area of less than 30 square meters on a level 1 site.

Demolition of a detached damaged building

N/A

Repair or replacement of a damaged outbuilding

N/A

Removal of sign, retaining wall, plinth or playground equipment

N/A

 

With all of this information: It could be classified under either; a pergola or a shade sail.
