A house built for heat.

A house built for heat

The Ibiza farmhouse is a working building before it is a pretty one. Its shape answers two problems: high summer heat and long months without rain. Walls of local stone are thick, sometimes very thick, and give back the cool of the night well into the afternoon. Windows are small and few, and rooms sit low under a flat roof. Nothing in that arrangement is decoration. The same answers repeat across the island, from the north to the slopes below Sa Talaia.

The plan is usually simple: a rectangular block of one or two storeys, rooms in a row, a porch at one end. Many fincas grew by addition rather than design, so a house can read as a cluster of roofs at slightly different levels, each one patched with lime. Whitewash is practical as well as bright. Lime reflects sun, closes small cracks and is easy to renew, which is why the older houses still look cared for even when nothing else has been done.

Water from the roof

Rain here is scarce and arrives in short, heavy bursts, so a roof is also a catchment. Water runs off the flat roof into a cistern, the aljub, built under the house or under the porch. The fall of the roof is calculated, not accidental. A channel leads through a filter of sand and stone and down into the tank. A wet winter filled it; a dry one set the limit on how many animals a farm could keep.

The aljub is often the oldest part of the structure, and the reason the house stands where it does. Some are vaulted chambers, some are simple tanks cut into the rock, and many survive under houses that have been modernised above them. Cistern water was for drinking and cooking. Washing, animals and the garden used wells or a small open tank fed from the same roof, and the household learned to spend water by the season. A cistern that is cleaned and repaired can still carry a garden through a dry summer.

The porch and the era

The porch, the porxo, is the outdoor room of the finca: a roof on stone piers, deep enough to shade a long table, turned to the morning or the evening sun according to the site. Work that could be done out of the direct heat happened there, and so did most of the eating and talking of summer. Behind it, the kitchen held the fire under a wide hood, with the chimney rising through the roof.

Beside the house stands a flat paved circle, the era, used for threshing grain and for drying figs, almonds and carob in the sun. A bread oven often sits close by, domed and built of the same stone. Some fincas keep a small chapel, a shed for animals, a mill for grinding. Together these pieces describe a farm that made most of what it needed and sold only what was left over. The yard between them was the working centre of the holding, not a garden.

What grows around the house

The fields around a finca were divided into small plots, because small plots are what dry land supports. Almond and olive trees, figs, carob and, in places, vines; vegetables in a walled garden close to the water. Little was wasted. Prunings became fuel, almond shells fed the oven, and carob pods fed animals as well as people. The pattern is still readable in the older parts of the island, even where scrub has taken the terraces back.

Dry-stone walls hold the soil on the slopes and mark where one holding ends and the next begins. They were built without mortar, each stone chosen and fitted by hand, and they shelter young trees from wind and salt. When a wall fails, the soil goes with the first heavy rain. Walking a path between those terraces is walking through the farm's accounts: what the land could give and where it stopped giving.

• AlmondBlossom in late winter, nuts in late summer, and a crop that tolerates dry years.
• CarobA deep-rooted tree whose pods fed animals and people.
• FigGrown near the house, dried on the roof and stored for winter.
• OliveOlder trees on terraces, pressed for the household before the market.
• Dry-stone wallBuilt without mortar to hold soil and shelter young trees.

Inside the thick walls

Inside, a finca is dark in summer and warmer than expected in winter, because stone gives up heat slowly in both directions. Ceilings are low, with beams of local pine or juniper, and rooms open into one another instead of onto a corridor. Benches, niches for lamps and storage, and a hearth wide enough to cook for a household: much of the furniture is masonry, because masonry does not burn and does not need replacing.

Lime goes inside as well as out. Whitewash brightens rooms that get little daylight, and it is mildly antiseptic, which mattered in a house with animals close by. Floors were stone or packed earth, later mosaic. Windows were placed for ventilation as much as for light, which is why so many of them sit high in a wall. In a restored finca these are the details that decide whether the building still works or has become a stage set.

A countryside of scattered houses

Ibiza's rural population lived in scattered houses and small hamlets rather than in compact villages, and the finca was the unit of that settlement. A house stood within sight of its fields and within walking distance of a parish church, which handled what needed a building: baptism, marriage, burial, the feast day. The parish, not the town, was the practical geography of the countryside. The result is the island's characteristic pattern, a low white house every few fields, still legible from Sa Talaia on a clear day.

That pattern has consequences for anyone walking. Scattered houses mean long tracks, shared wells and boundaries that are easy to cross without noticing. Most of the land around a finca is private, even where a path looks public. Gates exist for a reason, and a farm dog is working, not greeting. Rural walking on Ibiza works best when a gate is closed again behind you and a house is given the width of its yard.

The finca today

Many fincas are still farms, at least in part: a few terraces of almonds, a vegetable plot, animals for the household. Others have become rural tourism accommodation, which on Ibiza is a licensed category regulated by the Consell d'Eivissa and not a loose description. Restoration is slow and expensive. A house that looks untouched from the track may have a new roof, a rebuilt cistern and a solar array hidden behind the ridge. The old threshing floors and terraces often survive only because a house is still lived in.

Visitors meet the finca in three ways: as somewhere to stay, as a building passed on a walk, and as a name on a map that turns out to be a cluster of roofs with no services at all. The middle one is the most common and the least understood. A finca is a home and a workplace before it is scenery, and the rural roads are narrow because they were built for carts.

Keeping the countryside working

The finca survives because somebody keeps working at it. A roof of lime and earth needs renewing, a cistern needs cleaning, a dry-stone wall needs rebuilding after a storm before the soil goes with the next rain. None of that is landscaping. When a farm stops, the wall goes first, then the terrace, then the soil, and scrub takes the rest. The island's rural landscape is a maintenance contract, renewed every year.

For a visitor the useful habits are modest. Close a gate. Do not block a field entrance or a track junction, because a tractor needs the full width. Do not pick almonds or figs from a tree that belongs to a house. Carry water in and litter out. Where a path is signposted, stay on it; where it is not, assume the land is private until a sign says otherwise. The countryside looks like a farm because it is one.

• Close the gateA gate left open lets animals onto a road or into a crop.
• Park clearField entrances and track junctions need their full width for vehicles.
• Leave the treesAlmonds, figs and carob belong to the house, not to the path.
• Stay on the pathUnsignposted tracks usually cross private land.
