A farm that happens to have fourteen rooms
Son Blanc is a 19th century finca on 130 hectares of Menorcan farmland, rebuilt from ruin and run as a working farm with fourteen rooms attached. The farm is planned to produce 8 to 10 tons of vegetables and fruit a year across about 150 varieties, all to strictly ecological practice, and an independent reviewer puts about half of what the restaurant serves as already coming off the land. Hens, pigs, donkeys, cows, sheep and bees are part of the system rather than scenery, fertilising ground and handling pests. The kitchen works exclusively with organic seasonal produce delivered each morning by the farmers who grew it. Food and Kitchen is the pathway most hotels answer with adjectives. This one answers with a crop plan.

Cisterns, solar and geothermal
The estate's water runs through restored underground cisterns and an on-site recycling plant that irrigates every crop, which is a named system rather than a promise about stewardship. Energy is solar photovoltaic with battery storage, plus geothermal pumps. Those are the systems that decide how a building is heated, cooled and kept, and naming them is more than most properties manage. What they do not describe is air: no ventilation strategy, no filtration, no measurement of what a bedroom holds. The rooms are built from clay, stone, local and reclaimed wood and natural textiles, with no finish or emissions class published.
The gap worth naming
Son Blanc sells reconnection away from the digital world, and that is a programme rather than an engineering decision. Nothing is published about the wireless network, where its access points sit, or what a sleeping room reads, so EMF Harmony is empty. Nothing is published about lighting, so the property's careful daylight and its lamps are invisible to the record. Nothing is published on background noise, which matters more here than usual: this is a farmhouse that hosts concerts, parties and communal tables, and a guest room's separation from them is unrecorded. Four pathways are strong. The other four are simply unmeasured.

What is not publishedthe gaps we looked for and did not find
Son Blanc documents its farm better than most hotels document anything, and its building barely at all. Nothing is published on ventilation, filtration or indoor air, so the only air evidence here is the named energy plant, which says how the place is heated and cooled rather than what is breathed. Nothing is published on lighting: no colour temperature, no dimming, no blackout provision, on a property that markets itself as a retreat from the digital world. That framing is behavioural, not engineered. Nothing is published on network topology, access point placement or field levels in a bedroom, so EMF Harmony is empty. Nothing is published on background noise, on separation between the fourteen rooms, or on the acoustics of a farmhouse that hosts concerts and communal dinners, so Sound and Sensory Ecology is empty. The water record covers irrigation and the pool, and no drinking water source, treatment or analysis is published.

Not published is not unsafehow to read these scores, and what this index does not promise
A low score means a property has not published information. It does not mean the property is unsafe, unhealthy or poorly run.
These scores measure disclosure. These scores describe disclosure, not property quality. This index has no commercial relationship with the properties listed unless a badge on the listing says otherwise.
Conditions change, and we will not always know. Every record is a snapshot of what a property had published when we read it, and that date is on the page. Conditions change: a property can refit, change suppliers or replace a system at any time, and nothing requires it to tell us. We re-read records and ask properties directly for updates, but there will always be a gap between what is true today and what was published when we looked. Use this as a frame of reference for what to ask, not as a substitute for asking. Take your own questions to the property before you book, and tell us if you find something we have wrong.
We report what properties publish. We do not inspect, certify or vouch for any property on this index unless a listing says we assessed it on site, and we accept no responsibility for decisions made or outcomes experienced on the basis of what you read here.

Is Son Blanc Farmhouse low-EMF?
No measurement is published. Only 15 of the 92 properties we have researched publish any bedroom EMF information at all, so this is the industry norm, not an outlier.
