Home Automation for New Builds: The Complete Australian Guide
The best time to plan your smart home is before the concrete is poured — not because you need to decide every detail upfront, but because the infrastructure that makes smart home technology possible (cable, conduit, back-boxes) costs a fraction of the price during construction compared to retrofitting it later. If you're building a new home in NSW in 2026, this guide covers everything you need to know: what to specify, when to specify it, how to work with your builder, and what systems to choose.
Why New Builds Are the Best Smart Home Opportunity
When we consult with clients building new homes in NSW — whether it's a knockdown rebuild in Hunters Hill, a dual occupancy in Parramatta, or a custom build on the Central Coast — the conversation always starts in the same place: what does it cost to run all the cables during construction?
The answer, consistently, is less than you'd expect. During construction, cabling is labour-cheap: walls are open, ceiling spaces are accessible, and an experienced pre-wire team can cable an entire 4-bedroom home in a day or two. The same work in a completed home requires opening walls, repainting, and sometimes structural interventions that can cost three to five times more.
What to Pre-Wire in a New NSW Home
Data and Networking (Cat6A)
- Every bedroom: minimum 2x Cat6A data points
- Living room, dining room: 2x Cat6A each
- Home office or study: 4x Cat6A minimum
- Kitchen: 2x Cat6A (for appliances, displays, AV)
- Alfresco: 2x Cat6A (outdoor entertainment, security cameras)
- Every outdoor corner: 1x Cat6A (CCTV positions)
- TV wall positions: 2x Cat6A per location
- Access point positions (ceiling): 1x Cat6A per planned AP location
- Main comms cabinet: cable home-run from every outlet above
Speaker Cable
- Living room: 2x speaker cable home-run (stereo pair in ceiling)
- Kitchen: 2x speaker cable (1 stereo pair)
- Alfresco: 2x or 4x speaker cable (stereo or quad setup)
- Master bedroom: 2x speaker cable
- Additional bedrooms (optional): 2x speaker cable each
- Bathrooms (optional): 2x speaker cable each
- All runs back to central AV cabinet
Security and CCTV
- Every external camera position: Cat6A (for IP cameras)
- Door and window sensor positions: 2-core alarm cable
- PIR detector positions: alarm cable
- Front door intercom and video doorbell: Cat6A plus 12V power cable
- Smart lock positions: power and data cable to each door
- All alarm cabling home-run to security control panel position
Working With Your NSW Builder
Early engagement: We prefer to be involved from the design stage — before DA approval if possible, but certainly before construction commences. This lets us work with your architect and interior designer on keypad positions, touchscreen locations, AV cabinet sizing, and equipment room requirements.
Specification document: We provide a formal pre-wire specification document that your builder, electrician, and project manager can reference. This eliminates miscommunication about what goes where and who is responsible for each element.
Staged Rollout: Don't Feel Pressured to Do Everything at Once
- Pre-wire and infrastructure during construction: Run all cable, install all conduit, and establish the AV cabinet. This is the irreversible stage — everything after is upgradeable.
- Core system at handover: Networking (Ubiquiti UniFi), Control4 processor, and the systems you'll use daily from day one — typically audio, CCTV, and smart locks.
- Expand over 12–24 months: Add DALI lighting control, motorised blinds, home cinema, and additional automation as budget allows.

Frequently Asked Questions: Home Automation for New Builds in Australia
When should I engage a home automation installer for my new build?
As early as possible — ideally before the build contract is signed. The design stage is when keypad positions, AV cabinet sizing, TV wall locations, and conduit routes are cheapest to plan. At a minimum, engage us before the frame goes up, so pre-wire can be scheduled correctly within the construction programme.
Can I just pre-wire and choose the smart home system later?
Yes, and this is a perfectly valid approach. Pre-wire and conduit infrastructure during construction is largely agnostic — Cat6A, speaker cable, and alarm cable work with most professional smart home systems. If you're not ready to commit to a specific system, we can design the pre-wire to maximise future flexibility and complete the full Control4 installation when you're ready.
Is home automation worth the investment in a new build?
For most NSW clients building in 2026, yes — particularly the infrastructure investment. The pre-wire and networking components are low-cost during construction and high-cost to add later. The automation itself adds genuine daily-life value through convenience, security, and energy efficiency. See our guide to smart home costs in Australia for more detail.
