Eight guest structures in the village of Mastatal, Puriscal, Costa Rica, with a 16 room wattle and daub dormitory under construction for early 2027.
Eight guest structures in the village of Mastatal, Puriscal, Costa Rica, with a 16 room wattle and daub dormitory under construction for early 2027. The Ranch designed and built all but two of its more than 30 covered structures itself, in bamboo, cob, wattle and daub, light clay, natural plasters, and wood and stone from the surrounding forests and rivers. The Main House sits on the edge of a 235 acre private wildlife refuge with 7 kilometres of forest trails bordering La Cangreja National Park. There is no WiFi network.
Interior finishes are named per building: lime and clay plaster at Bernie's Bunkhouse, earthen plasters and floors at the Starboard Cork, tadelakt showers at La Malanga, the Honey Hut and La Casucha, and a bamboo floor at the Hooch. The lime is bought as powdered hydrated lime, having earlier been burnt quicklime from a regional kiln made into putty on site, and the plasterers who developed the techniques are named. All timber is sourced and milled in the region and often from the Ranch itself. Nothing is published on mattresses, linen fibre or cleaning chemistry.
The Ranch publishes that it has no WiFi, with internet reachable only through a guest's own phone on the local Kolbi cell network. The water is stated to be potable and guests are asked not to bring disposable bottles, with no source, treatment step or test result described. The Main House, which holds guest bedrooms and a six bed bunk room, is disclosed as the busiest building on the campus and the place where all meals are served. Nothing is published on lighting.
All eight areas, for every record. Each row opens to what was published, where we read it and when.
Publishing something is not the same as it being good. Every line below was read and placed by a person, not scored by a machine. What each rung means
Named means the property published something you can look up: a brand, a product or a number. Stated means it says so with nothing behind it. Not published means we looked and found nothing, which is a gap in our reading and not an answer about the building.
The air in a closed room is what you breathe for eight hours. What decides it is the filter grade, the fresh air rate, and whether damp has ever been looked for.
We found nothing published on this. That is a gap in what we could read, not a finding about the building.
You drink it, cook with it and stand under it. What is in it depends on the source and on what, if anything, filters it, and both are things a property can name.
The property states that the water at Rancho Mastatal is potable and asks guests not to bring disposable water bottles, with no source, treatment step or test result described.

Light is what tells a body the time of day. The part a building controls is what its fittings emit and when, which a named product or a colour temperature makes checkable.
We found nothing published on this. That is a gap in what we could read, not a finding about the building.
Wiring, routers and devices put electromagnetic fields in a room. What a building decides is where they sit relative to the bed, and whether anyone has measured it.

What a kitchen cooks with and where it buys are the parts of a stay you take inside you. A named oil, a named supplier or a published share is checkable; “healthy” is not.
