Residential Drafting and Building Design in the Northern Territory

Planning in the Northern Territory runs under the Planning Act 1999 and the NT Planning Scheme 2020, which applies across the Territory. Building work is controlled by the Building Act 1993.

• Planning approval. Where a development permit is needed, it is decided by the Development Consent Authority. In the low density residential zone (Zone LR), a single house that meets every relevant scheme requirement does not need development consent.
• Building permit. Building certification in the NT is carried out by private, registered building certifiers. Before work starts, a certifier checks the plans and issues the building permit, then lodges it with the Director of Building Control.

Where your property sits also matters. Building control areas are split into tiers, and outside the Darwin, Lake Bennett and Alice Springs regions only part certification applies to a detached house.

We design to the scheme's requirements for your zone where the site allows, so the project can go straight to a building certifier. If a design needs a variation, such as a reduced setback, it needs a development permit, and we prepare the drawings and the reasons. Tropical climate, cyclone regions and wind classification shape the structure, so we bring the engineer in early.

In the NT a granny flat is called an independent unit. In most cases you can build one without planning approval if it meets all the requirements of the NT Planning Scheme 2020. Building approval is separate, and if planning approval is needed it must be in place before occupancy certification. We check the scheme rules for your lot first.

Most residential land in Zone LR is limited to single dwellings, so a duplex is often not straightforward. A proposed amendment to allow more infill in Zone LR has been released for comment. We check the current position for your lot before any design work.

The Northern Territory has not adopted the NCC 2022 increase to energy efficiency for homes, so the earlier NCC 2019 requirements still apply. A whole-of-home rating is optional rather than required. We confirm the current requirement with your energy assessor and certifier for each job.

We prepare concept plans, development permit drawings where needed, and building permit sets for houses, independent units and extensions. We work Australia-wide, with our own team in every state, and we can coordinate the whole project, bringing in the surveyor, engineers, energy assessor and building certifier and handing a clear set to your builder. We bring 10+ years combined experience and 100+ residential projects.
