New-build villa
The panel is yet to be created, partitions are not up, and no decision is constrained by what already exists.

Backbone — network and Wi-Fi
EssentialEverything else depends on it. Cameras, Wi-Fi access points, intercom and access control are powered by this network, not by wall sockets.
- Cabling
- Cat6A to every fixed point, including those nobody wants yet, and 10 Gbps switching at the core. This is not over-specification: it is what absorbs the fibre plan of five years from now, 4K cameras, and file transfers between machines in the house, which never touch the internet. A cable pulled during structural works costs the price of the cable; pulled afterwards, it costs a chase in the wall.
- UniFi
- Rack and power
- Patched rack in the plant room, ventilated, on a UPS. PoE 802.3at/bt switches sized with headroom — cameras are always added after handover.
- UniFi
- Wi-Fi coverage
- One access point per floor at minimum, positioned on the drawings and not at the end of the project. The solid concrete walls of a Moroccan villa are not solved with a repeater.
- UniFi

Security and access control
EssentialThe item that triggers the call, and the one whose positions are frozen when the partitions go up.
- Video surveillance
- UniFi Protect cameras and IP door station, PoE powered from the rack. Same controller, same app and same account as the network already installed: one interface to learn, one estate to keep updated. Hikvision remains the fallback when the budget is tighter. Fields of view agreed on the drawings, with the client, before the pour.
- UniFi
- Hikvision
- Access control
- A UniFi Access reader beside the handle, not a connected handle. The handle stays mechanical — it is what opens the door the day nothing else responds — and the badge or face recognition is added on top. The Moroccan market installs entry-level connected handles by the thousand: they put lock, electronics and battery in the hardest part to replace. This pair is also the only one compatible with Apple HomeKit and HomeKey: you open with your phone, the card living in the Apple or Google Wallet. Where cabling is impossible, an Aqara handle with mechanical override is the fallback.

- Intruder alarm
- Wired. On a new build, wireless solves no problem you have not created yourself by forgetting a cable.
Automation
EssentialThis is the only moment in the building's life when bus cabling costs almost nothing.
- Core system
- KNX, with no serious alternative on a new build. ETS programming, and the project file handed over at completion — that is what leaves you free to change integrator.
- KNX
- Lighting
- KNX actuators in the panel — Zennio in volume, ABB or Schneider on the larger ratings. DALI in areas with a high fitting count: living room, facade, architectural lighting. Lutron where the dimming requirement is genuinely high end.
- KNX
- Zennio
- ABB
- Schneider Electric
- DALI
- Lutron
- Shading
- Somfy for shutters, blinds and pergolas, brought into KNX through a gateway. Keypads by Basalte or Gira where the design matters, Zennio elsewhere.

- Air conditioning
- Ducted or multi-split driven by Airzone with a KNX gateway. Temperature and humidity sensors per zone. Control per room, not per floor — that is the difference between real comfort and a bill.

- KNX
Energy
RecommendedThe item you regret not preparing, because it can only be recovered by opening the panel again.
- Metering
- Sub-metering per circuit at the panel. Without measurement, no discussion about consumption is possible later — you are left with impressions.
- KNX
- Autonomy
- Space and circuits reserved for a generator or a UPS, even if the equipment is not ordered. Load shedding is programmed the day the source arrives.
Outdoors
RecommendedThese are the functions that set a villa apart from an apartment, and they are cabled before the landscaping.
- Gate and vehicle access
- Power and bus pulled to the gate during the trench, with a spare duct. Reopening a paved driveway costs more than the gate.
- Pool and irrigation
- States and commands brought into KNX rather than one more proprietary box. The aim is one interface controlling the house, not five apps.
- KNX
Audio and video
OptionalPrepared on a new build, decided later. The cable costs little; the equipment can wait.
- Pre-wiring
- Pull the speaker and video runs now, and leave them capped. The cheapest item on site at this stage, one of the most expensive two years later. When the equipment is finally chosen, UniFi audio and its amplifier stay on the controller already in place; Sonos is the fallback where the network is not UniFi.

Supervision and interfaces
RecommendedA comfort layer, never a dependency.
- Dashboards and notifications
- Home Assistant as an overlay — dashboards, notifications, third-party integrations. Never as the core: lighting and air conditioning must keep working with the server switched off.
- Home Assistant
Ecosystem and assistants
RecommendedThe question every owner asks, and the one the market is vaguest about: does it work with Siri or Google? Yes — on top of the bus, never in its place.
- Apple HomeKit
- KNX devices are exposed to the Home app and Siri through a bridge. Voice control becomes a convenience, not a dependency: if the bridge goes down, the wall switches keep working.
- Apple HomeKit
- Google Home
- Same principle, with one caveat worth knowing: the integration runs through an online service whose terms and behaviour can change without notice. Treat it as a comfort, not as a building function.
- Google Home
- The pivot
- Home Assistant is what exposes the bus to HomeKit, Google or Alexa as you choose, without the core of the system depending on any of them. Changing voice assistant must never mean touching the panel.
- Home Assistant
- Matter
What we advise against in this case
Closed proprietary systems — Control4, Crestron — on a new-build villa. Every modification goes through an authorised dealer, and the day that dealer stops trading the installation becomes unusable by anyone else. This is not a question of equipment quality, it is a question of who holds the keys in ten years. We also advise against connected bulbs as primary lighting, and against any basic function — switching on, heating, opening — that depends on an online service to respond.
