It is the question every villa owner asks: how much should you budget for a smart home system worthy of your property? The honest answer is "it depends" — but that answer alone helps no one. This article breaks down the real budgets, line by line, for three tiers of high-end residential smart home systems in 2026.
The figures presented here come from our hands-on experience at AV Concept Products. They reflect real projects, installed and programmed by our teams in France, Switzerland, and Monaco. These are not theoretical estimates.
To simplify a complex subject, we break projects down into three service tiers. Each tier includes equipment, programming, installation, and commissioning.
From €15,000 to over €200,000, each integration tier addresses different needs
Essential Tier — €15,000 to €30,000
The Essential tier covers the fundamentals of the connected home. It is aimed at owners who want improved everyday comfort without turning their villa into a spacecraft.
What is included:
Connected lighting in the main rooms (living room, kitchen, bedrooms, entrance hall) with dimmers and programmed scenes
Motorised blind and shutter control (4 to 8 zones)
Multi-zone smart thermostat (3 to 5 heating/cooling zones)
Centralised smartphone control (single application)
Recommended system:Control4 with CA-1 or CA-10 controller. Investing in a scalable ecosystem allows you to add features later without starting from scratch.
What is not included: multi-room audio, home cinema, video surveillance, access control, pool management.
Comfort Tier — €30,000 to €80,000
The Comfort tier is the sweet spot of the high-end smart home market. This is where the return on investment is most favourable, as the system covers the core everyday use cases with a high level of finish.
What is included (in addition to Essential):
Full villa lighting with dimmers in every room, controlled exterior lighting, and circadian scenes
Multi-room audio across 4 to 8 zones with quality in-ceiling speakers (CI loudspeakers from brands such as KEF, Klipsch, or B&W) and dedicated sources
Home cinema integrated into the smart home control with a complete "Cinema" scene — motorised screen, Sony or Epson projector, Denon or Marantz amplifier
Motorised blinds, shutters, and curtains throughout the villa
Multi-zone air conditioning controlled with seasonal scenes
Connected video intercom + smart lock
5 to 10 personalised scenes including a Cinema scene
Wall-mounted tablets or touchscreens in 2–3 key rooms
Recommended system: Control4 with EA-5 controller and an extended ZigBee network. For new builds, a KNX backbone for lighting and blinds with Control4 as the supervisory layer is an excellent option.
Prestige Tier — €80,000 to €200,000+
The Prestige tier is for exceptional villas where every detail is considered, every interaction is seamless, and every subsystem is of professional grade. This is the domain where the integrator truly makes the difference.
The Prestige tier integrates all systems within a unified architecture
What is included (in addition to Comfort):
Hybrid KNX + Control4 (or Crestron) architecture for maximum reliability
High-fidelity multi-room audio across 10 to 20 zones with dedicated amplification per zone, premium architectural speakers, and acoustic treatment
Complete private cinema room with 4K laser projection, Dolby Atmos audio, motorised seating, and an EdgeFrame TrueAcoustic or CeilingScreen Tensioned X screen
Advanced energy management: real-time consumption monitoring, solar production, battery storage
Integrated IP video surveillance (8 to 16 cameras) with NVR recording and smartphone alerts
Crestron or Control4 interface on touchscreens in every main room
Recommended system: KNX for the building infrastructure + Control4 EA-5 or Crestron for AV control and the user interface. For residences exceeding 500 m², Crestron is often the natural choice given its processing capacity and depth of customisation.
What Influences the Price
Beyond the service tier, several factors can significantly shift the budget:
Villa size: a 150 m² villa and a 600 m² villa do not require the same number of modules, actuators, and control points. Cost scales almost linearly with usable floor area.
New build vs. renovation: in new construction, cabling is planned and run during the shell phase. In a renovation, cable routing can represent 20 to 30% of the total budget, and may require more expensive wireless solutions.
Number of audio/video zones: each multi-room zone requires an amplifier (or an amplifier output), speakers, and dedicated cabling. Moving from 4 to 12 zones can add €8,000 to €25,000 depending on speaker quality.
Level of interface customisation: a standard Control4 interface is included in the system. A fully bespoke Crestron interface with custom design is a project in itself, and can represent €5,000 to €15,000.
Exterior spaces and outbuildings: garden, terrace, pool house, garage, gate — every outdoor zone adds cabling, weather-resistant equipment, and programming.

* KNX requires a complementary audio/video system (e.g. Sonos, Control4 Triad) as it does not natively handle multi-room audio or AV control.
A well-designed smart home system is not purely a cost centre — it generates measurable savings:
A well-designed smart home increases property value and reduces energy costs
Energy: intelligent control of lighting, heating, and air conditioning reduces consumption by 15 to 30% according to studies (source: KNX Association). For a villa with an annual energy bill of €5,000 to €10,000, the saving amounts to between €750 and €3,000 per year.
Property value: a professionally integrated smart home system is a major selling point in the luxury market. Estate agents estimate that a complete smart home installation can add 3 to 8% to a property's value.
Insurance: some insurers offer premium reductions for residences equipped with leak detection, video surveillance, and presence simulation.
Comfort and wellbeing: circadian lighting, controlled air quality, and automatic temperature management improve daily wellbeing — a benefit that cannot be quantified, but is very real.
Frequently Asked Questions
Does the entire house need to be wired for KNX?
No, a mixed approach is often the right call. The KNX bus can cover critical functions (lighting, blinds) while comfort functions (audio, video) use the IP network. This is the approach we recommend most frequently at AVCP.
Does the price include programming?
Yes, all our budgets include full scene programming, system calibration, and user training. Programming typically represents 15 to 25% of the total budget and makes a considerable difference to the final experience.
What is the annual maintenance cost?
For a well-installed system, annual maintenance is modest: €500 to €2,000 for software updates, checks, and seasonal adjustments. We offer maintenance contracts tailored to each installation.
Can you start small and expand later?
Absolutely — and it is actually recommended. The key is to put a scalable network and smart home infrastructure in place from the outset (cabling, technical rack). You can then add audio zones, cameras, or new features year by year.
Investment in a quality smart home system pays dividends over decades of daily use
Conclusion
The cost of a high-end smart home system varies considerably depending on scope, the chosen platform, and the level of customisation. But one constant holds true: the investment in a professional installation, designed and programmed by a certified integrator, is always repaid through daily comfort, energy savings, and property appreciation.
