Smart Home for a New Villa: What to Wire Before the Walls Close
If you are building or fully renovating a villa in Dubai or Abu Dhabi, the cheapest moment to make it a smart home is before the walls close. Cabling that costs a few thousand dirhams during first fix costs ten times more to add later, and some things cannot be added at all without opening finished walls. This checklist is what we ask every client to plan with their contractor, whether they automate now or in five years.
Short version: run a KNX bus cable and a Cat6A network cable to every room, bring every light circuit and curtain motor back to a central panel, and leave a rack space for equipment. Everything else can wait.
The wiring checklist
| Item | What to run | Where | Why now |
|---|---|---|---|
| KNX bus | KNX-certified green bus cable (2 twisted pairs) | Every switch position, every room ceiling, each AC zone, each curtain, the entrance and gate | Needed for KNX lighting, climate and curtains; impossible to add neatly later |
| Lighting circuits | Each circuit as its own cable back to the distribution board, not daisy-chained between rooms | Living areas: separate circuits for ceiling, cove, wall, accent. Bedrooms: 2 to 3 circuits | Lets each circuit dim and scene independently from one panel |
| Network | Cat6A, 2 points per room, plus points at every TV, access point, camera and intercom position | All rooms, ceilings for Wi-Fi access points, garage, garden, pool | Reliable Wi-Fi mesh and cameras depend on cabled access points |
| Curtains and blinds | Power and KNX (or motor control) at the top corner of every window | All windows you may motorise | Motors need power at the window; adding it later means chasing walls |
| AC control | Control cable from each indoor unit or FCU to the thermostat position; keep the branded controller cable too | Every zone | Allows KNX or smart thermostats with proper setpoint control |
| Audio | Speaker cable from each room ceiling to the rack; conduit in walls for future speakers | Living, dining, majlis, master, kitchen, outdoor | Invisible or ceiling speakers must be cabled |
| Cinema room | Conduits from projector position and screen wall to the rack; dedicated power; Cat6A | Cinema or media room | Projector and screen cabling is in the ceiling |
| Security | Cat6A to every camera position, intercom, gate and door lock; power for gate motor | Perimeter, entrances, driveway, pool | PoE cameras need cable; wireless cameras are a compromise |
| Rack room | A ventilated cupboard or room, 1 m by 1 m minimum, with power and all cables terminating there | Central, cool, near the distribution board | Every system lives here; without it equipment ends up in a bedroom wardrobe |
| Distribution board | Space for KNX actuators and dimmers: usually a second board or a larger one | Next to the main board | KNX modules need DIN rail space |
Decide this before first fix
- KNX, Control4 or both. KNX for the building (lighting, climate, curtains), Control4 for the user interface and entertainment. See KNX vs Control4. If you are unsure, run the KNX cable anyway; it keeps both options open.
- Keypad positions. One KNX keypad per room entrance replaces a bank of switches. Decide the positions on the plan so the electrician runs one bus cable there, not six power cables.
- Which windows get motorised curtains. Power at the window is cheap now, expensive later. If in doubt, run it.
- Where the rack goes. Not under the stairs without ventilation and not the garage in a Dubai summer. A cool internal cupboard with an AC supply.
- Who programs it. Choose the integrator before the electrician starts. We supply cabling drawings and a device schedule the contractor follows, and we check the first fix before plastering.
Common mistakes we see on site
- Lighting wired room-to-room in loops, so circuits cannot be controlled separately.
- No bus cable to the AC thermostat positions, so climate ends up on the branded controllers.
- One network point per floor, then a Wi-Fi system that cannot cover a villa with thick walls.
- No conduit to the garden, so outdoor lighting, cameras and speakers are added on surface trunking.
- The rack placed in a hot garage; equipment fails within two summers.
What it costs at first fix
For a 5-bedroom villa, the extra cabling for a full smart home (KNX bus, individual lighting circuits, Cat6A, curtain power, audio and camera cabling) typically adds AED 15,000 to 35,000 to the electrical contract. The automation equipment and programming on top of that is in our home automation cost guide. Done later, the same cabling in a finished villa costs several times more and involves opening walls.
How we work with your contractor
- Free consultation on the architect's plans.
- Cabling drawings and a device schedule for the electrician, with keypad, speaker and camera positions.
- First-fix inspection before plastering.
- Installation and programming at second fix and after handover.
- Walkthrough with the family and support afterwards.
