On a hotel, a wiring mistake can be quietly fixed — standard walls, accessible finishes. On a luxury villa, that's a different story. A chase through marble can't be undone. A drop ceiling added to a salon with bespoke mouldings will always show. This guide breaks down circuit by circuit what each space of a villa needs, with an estimator that generates a floor-by-floor breakdown and lets you send the result directly to WhatsApp.
What happens when the integrator arrives after the architect
The architect delivers the plans — natural stone walls already clad, ceiling mouldings complete, fitted joinery installed. The CFO/CFA integrator shows up for the first time. Result: 3 chases cut into finished stone walls, a drop ceiling added in the salon to conceal SMATV cables, the electrical panel wedged into a 60cm service corridor. The villa is beautiful, but the installation is a permanent visible compromise. 350,000 DZD in unplanned rework. Solution: bring the integrator in at sketch stage, not after finishes are done.
The golden rule: invisible as the objective
A successful villa installation doesn't show.
- CFO and CFA cables cast into floor slabs before closure — no chases after the fact
- Electrical panels integrated into bespoke joinery — not in a service corridor
- WiFi access points flush-mounted in ceilings, colour-matched to the room's finish
- Perimeter cameras integrated into exterior fittings or architectural elements
- Video intercom and gate badge reader built into the entrance pillar from day one
- Multi-room audio cables run under slab before tiling — never surface-mounted

Home automation in an Algerian villa — scenes that actually work
- "Leaving for holiday" — one tap: all lights off, AC cut, blinds closed, perimeter alarm armed, cameras on continuous record.
- "Evening in the salon" — lighting at 30% warm tone, blinds closed, AC at 23°, TV on selected source.
- "Night security" — interior zones disarmed (bedroom/bathroom circulation), exterior perimeter armed, motion-triggered nocturnal lighting.
- "Arrival" — owner's phone detected nearby: gate opens, entrance lights at 100%, AC starts 5 minutes before arrival.

Frequently asked questions
When should the CFO/CFA integrator be brought in?
At concept / pre-design stage — before plans are finalised for planning permission. That's the only moment when technical routing decisions can influence the drawings without additional cost.
Is a generator needed for a private villa in Algeria?
On a villa with full automation, centralised AC and a security system, a Sonelgaz outage cuts everything simultaneously. A 5–10 kVA generator with ATS protects the whole property — an investment of 300,000 to 600,000 DZD that pays back on the first extended outage.
SMATV or IPTV in a villa?
SMATV is more reliable without a stable fibre connection. IPTV is superior if fibre is available — unified interface across all screens. Decision must be made before the shell structure: the two systems use different cabling.
