Europe
Lighting, shades, cinema, network, security, and backup power for villas, apartments, hotels, and yachts from Monaco to Mykonos — designed and commissioned by one team, executed with the qualified local firm each country requires, and supported from Warsaw and New York.
How We Work Here
A European villa answers to its own country: who may hold the tools, who rules on the facade, how many kilowatts the meter allows, and which cable the island hangs on. We design for all of it from the drawings, commission on site with the qualified local firm, and are still there after the last trade leaves.
01 · Warsaw
Our European work runs from Warsaw, with projects across the Mediterranean on a project basis: design from the drawings, site visits at the milestones that need them, installation and commissioning on site, and Cave Watch support afterward.
02 · Rules
Every market has a body that rules on the facade: Monaco's DPUM, Italy's Soprintendenza and landscape authorization, the Consorzio Costa Smeralda's architecture committee, Greece's Archaeological Service, Konstancin's conservator. The technology drawings go into the file from the start.
03 · Power
Italy's default contract is 3 kilowatts, the Cyclades hang on one cable corridor, and the Gallura grid failed in the 2026 heat. The contract is sized, the rack sits on battery, and any generator is sited, enclosed, and registered the way the country requires.
04 · The Boat
Port Hercule and Porto Cervo have shore power at every berth, and the yacht's network, cameras, and control can join the villa's when she ties up. The 2024 Monaco refit is the reference.
Where We Work
The French and Italian Riviera, the islands and the Aegean, a protected lake, and the capital our European operations run from. Six markets have their own page.
The French and Italian Riviera
Monaco and the Côte d'Azur, Portofino and Liguria: villas under the DPUM, the loi Littoral, and the Soprintendenza, with the yachts of Port Hercule a few hundred meters from the front door.
Authorization for everything, and Port Hercule at the door
A 1966 ordinance means no change to a Monaco building without authorization, only Monegasque firms may work in the Principality, the loi Littoral keeps the Côte d'Azur's shoreline unbuilt, and the yachts berth two blocks from the apartment. Our 2024 refit was here.
Landscape authorization first, 3 kilowatts by default
Every exterior change in Portofino's protected zone needs a landscape authorization before the building permit, the standard Italian power contract is 3 kilowatts, and fiber changes street by street between Portofino and Santa Margherita. Villas on a hillside that moves.
The Islands and the Aegean
The Costa Smeralda and the Athens Riviera and Mykonos: a consortium that approves every antenna, a grid on a subsea cable, a summer population that multiplies, and villas that close for the winter.
The Consorzio approves every antenna and generator
Membership in the Consorzio Costa Smeralda is compulsory, its Comitato di Architettura approves exterior lighting, antennas, generators, and air conditioners, and its building regulation wants a power report before works begin. Porto Cervo has a few hundred year-round residents and 700 berths.
Cycladic walls, a subsea cable, and the Archaeological Service
Permits without the Archaeological Service's sign-off are illegal, Mykonos' draft plan wants four stremmata for a villa, the Cyclades hang on a subsea cable from Lavrio, and Attica went to red-code wildfire risk in 2026. Villas that fill in June and close in November.
Lake Como and Warsaw
Historic villas on a protected lake, and the capital where our European operations are based, with its own villa district on the heritage register.
The Soprintendenza, 120 days, and a 3-kilowatt meter
The Soprintendenza reviews any external renovation and can take 120 days, replacing a window needs a CILA or SCIA, the default power contract is 3 kilowatts, and fiber reaches a quarter of Cernobbio's addresses. Villas at €10,000 to €15,000 a square meter.
Our European base, with a villa district on the register
Our European operations are based here. Konstancin-Jeziorna's villa district is on the heritage register as a whole, Wilanów prices run near 19,200 złoty a square meter, Stoen Operator runs the grid, and a generator with a transfer switch is agreed with the distributor first.
What These Villas Ask For
Lutron HomeWorks, Ketra and Rania light, Palladiom keypads, and shades that disappear into the ceiling.

Questions We Hear
Cave Group does. We are a Crestron Elite Gold Partner and Lutron Gold Dealer with European operations based in Warsaw, and we design, install, and service lighting control, motorized shades, home cinema, audio, networking, security, and backup power for villas and apartments in Monaco and on the Côte d'Azur, in Portofino and Liguria, on the Costa Smeralda, on the Athens Riviera and Mykonos, on Lake Como, and in Warsaw, and for the yachts berthed beside them. In 2024 we completed a full technology refit of a 65-meter superyacht during a yard period in Monaco. The Monaco refit →
In Warsaw, where our European operations run from. The Mediterranean projects run on a project basis: design from the drawings with your architect, site visits at the milestones that need them, installation and commissioning on site with the locally qualified electrical firm the country requires, and Cave Watch remote support afterward. Our offices in the United States are in Long Island City, New York, and Fairview, New Jersey.
It changes at every border, and we plan for it. In Monaco only Monegasque building companies may work without specific government approval; in Italy the firm must be qualified under DM 37/08 and issue a Dichiarazione di Conformità; in Greece a licensed electrician certifies the installation to HEDNO before it is connected; in Poland the electrician holds a SEP qualification; in France the installation follows the 2024 NF C 15-100. We design, program, and commission the system, and the qualified local firm executes and certifies the electrical work.
Expect it. Monaco's DPUM authorizes changes to interior layout and exterior features alike; Lake Como's and Portofino's exterior works go through the Soprintendenza and the landscape authorization; the Consorzio Costa Smeralda's architecture committee approves exterior lighting, antennas, generators, and air conditioners; Mykonos needs the Archaeological Service's sign-off; Konstancin's villa district is on the heritage register as a whole. We draw the exterior devices for the application and keep the system inside, where the reviewers have no say.
For the contract and the grid. Italy's standard residential contract is 3 kilowatts and exceeding it trips the whole house, so the upgrade is specified with the electrician and the rack sits on battery; the Cyclades hang on a subsea cable corridor and have lost power in August; the Gallura grid failed repeatedly in the 2026 heatwaves. A generator is a fixed noise source under Italian law even in standby, needs its own HEDNO registration in Greece, and needs the distribution operator's agreement in Poland when it has an automatic transfer switch, so it is sized, sited, and papered with the local firm. Generator and UPS planning for the rack →
Monaco Telecom's fiber reaches 10 gigabits, the Consorzio brought fiber to Porto Cervo, TIM's fiber reaches a quarter of Cernobbio's addresses and changes street by street in Liguria, and Starlink has covered Italy and Greece for years. We confirm what reaches the villa and design the network with two paths and automatic failover, so the cameras, the remote access, and the house survive a cut. Starlink as a second connection →
Yes. Port Hercule has shore power and water at every one of its 700-plus berths and Marina di Porto Cervo at each of its roughly 700, and a yacht's network, cameras, and Crestron control can join the villa's when she ties up, so the owner's app, the crew's panels, and Cave Watch see one system. The 2024 Monaco refit put Starlink Maritime with Peplink failover, UniFi, Crestron 4-Series, Kaleidescape, and Trinnov on a 65-meter yacht. Yacht technology →
Yes. We take over existing Crestron, Lutron, and Savant systems, and when a system can no longer be supported, whatever the brand, we plan a replacement that reuses the wiring already in the walls. It starts with a survey: we assess and document the equipment, recover or rebuild the programming, replace what has reached end of life, and bring the result under a Cave Watch support plan so the next problem has a phone number. Crestron upgrade paths →
Before the authorizations are filed. Portofino's landscape authorization is valid for five years, the Soprintendenza can take 120 days, the Consorzio Costa Smeralda wants a power report before works proceed, and Monaco authorizes the interior layout as well as the facade, so the technology drawings belong in the architect's file from the start. Lighting control changes the panel schedule, shade pockets change the framing, and the conduit between the villa, the pool, and the gate goes in before the terraces are laid. When to engage on new construction →
It depends on how many rooms are lit, shaded, and wired for sound and video, how many buildings there are, and whether the villa is new or occupied. We price from drawings, room by room, so you can see what each decision costs and cut or add with the numbers in front of you. Travel and commissioning are agreed during planning, not added at the end, and every device we specify carries CE marking. What whole-home automation costs →
Yes. The same team runs the lighting, control, and audio at Casa Cipriani in Lower Manhattan, we are Lutron HTI certified for guest-room control, and we integrate property-management systems such as Opera Cloud, Mews, and StayNTouch. The Mediterranean is building: Four Seasons opened its first Mykonos resort with 94 keys in June 2026, Conrad Athens The Ilisian opened 278 rooms in April 2026, Palm Beach Cannes reopened as the Riviera's first private members' club after a $273 million restoration, and the Michelin Guide is expanding in Greece in 2026. Guest-room control, a dining room's lighting and sound inside Monaco's noise limits, and a club's access and video are the hospitality page's work. Hospitality →
Yes. Cave Watch monitors the network, the control system, audio-video, and lighting remotely and fixes most faults without a visit; the rack sits on battery with a second internet path, so an outage does not leave the villa dark to us; and the house opens, cools, and lights from the app the day before you arrive. Porto Cervo has a few hundred winter residents and Mykonos closes from November to March, so the system has to report in on its own. Cave Watch support →
