Buildings eligible for MultiProof

For your design to be eligible for MultiProof it needs to be for a whole building.

To be eligible for MultiProof, you must submit a design for a ‘building’ as defined by the Building Act.

Your application must also relate to the building as a whole, but does not need to include features that are specific to a building site such as foundations or drainage. Building products, systems and designs for part buildings are not eligible.

You also must also intend and be able to build the approved design at least 10 times in a two year period.

Suitable building and construction types

Your MultiProof design can be for any kind of building. This includes the following types:

  1. Building types
    • residential
    • conservatories and garden rooms
    • garages and carports
    • sheds and glasshouses
    • horticultural (such as tunnel houses)
    • agricultural (such as barns and stables)
    • educational (such as classrooms)
    • commercial/industrial (such as service stations)
    • tents and marquees.
  1. Construction types
    • detached or semi-detached
    • single or multi-level
    • light timber framed
    • light steel framed
    • incorporating innovative building methods
    • flat pack
    • prefabricated/transportable
    • modular construction
    • engineered solutions.

Design alternatives

Your MultiProof can include design alternatives as long as they have been approved. This gives you flexibility to cater for local conditions (such as wind or earthquake zones).

It also means your clients have choices. For example, a residential design could offer different:

  • cladding types
  • window locations and configuration
  • bathroom layouts
  • kitchen arrangements.

A MultiProof can also be issued if you have a flexible building design involving building modules and connections between them. This allows you or your client to put the building together in the best way for the site and for their needs.

Parameter based variations

An application can also be submitted with parameter based variations for more flexibility with your MultiProof.

Parameters are a set of design rules that any changes to your design would comply with. Parameter based applications are suited to low risk buildings and those that use standardised construction details or building systems.

They may also work well for simple buildings outside of the scope of the acceptable solutions that are designed using software programmes.

This option could be useful if you are:

  • a group home builder offering a wide range of plans and customisation
  • a franchise owner marketing a range of buildings such as farm sheds or garages that vary in size.
