Kōwhai 60
Splice Design Ltd is completing the drawings for this design. Your reservation keeps the published price. We will email you when the plans are available to order. Once you order, we adapt them to your property.
60 m², two bedrooms
The Kōwhai has two bedrooms, one bathroom, built-in storage and a living area with room for a full dining table.
The building is 10.4 M long. We review boundary clearances and other local planning requirements when adapting the plans for your property.
Architectural drawings and supporting documents
A plan set includes architectural drawings, structural bracing details, material specifications and consent-exemption documents. It includes a licence to build the design once, anywhere in New Zealand. An NZRAB Registered Architect adapts and signs the plans for your property.
You receive the drawings and documents your chosen builder uses to prepare a quote, order materials and carry out the work. Building costs are separate from the plan-set price.
Building-consent exemption requirements
Since January 2026, homes up to 70 m² can qualify for a building-consent exemption when its conditions are met, including licensed design and building work. The Kōwhai 60 is 60 m².
Local planning rules still apply. These include boundary clearances, how much of the section can be built on, outdoor space and any property-specific restrictions. We review these requirements when adapting your ordered plans.
If your section cannot take the design, the plan set is refunded in full.
