Builders in Exo Gonia

Agricultural terracing converting to houses, on the island's best morning aspect.

Short answer

Exo Gonia occupies an east-facing hillside above the island's central plain, with extensive agricultural terracing and a stock of farm buildings and canava converting to residential use. The terracing is both the character and the main technical constraint.

What to expect

Typical durationReasonable — vehicle access to most of the village
Cost bandLow to moderate
Permit requiredTraditional character in the core — check specifics
Seasonal constraintYear-round; terracing work before winter

The ground and the access

Exo Gonia climbs an east-facing slope looking across the central plain toward Kamari and the sea. The whole hillside is terraced — generations of dry stone walls creating the level ground that made agriculture possible.

For construction that terracing is the central fact. Any building here sits on, above or below retaining structures whose stability depends on drainage through and behind them. Rebuilding a collapsed terrace in impermeable blockwork, which owners frequently do for neatness, is how a stable hillside becomes an unstable one. See retaining walls.

The east aspect is a genuine amenity: morning sun, sheltered from the strongest westerly exposure, and much more comfortable outdoor space than a west-facing plot in the afternoon.

What is built here

Traditional village houses in the core, agricultural buildings and canava on the terraces, and increasing conversion and new residential building.

  • Agricultural building conversion, which is rewarding and needs the same care as any heavy traditional structure. See property renovation.
  • Dry stone terracing, which drains through itself and must keep doing so. See masonry and stonework.
  • Canava, partly buried and with cave-like moisture behaviour.
  • Cisterns, associated with the agricultural use.

What matters most on a job in Exo Gonia

  1. Respect the terracing. Rebuild in a way that drains, not in a way that dams. This is the single most consequential decision on a hillside plot here.
  2. Map the water across the whole slope. What arrives from above crosses your terraces on its way down.
  3. Use the aspect. East-facing outdoor space is comfortable through the afternoon in a way west-facing space is not. Design for it.
  4. Treat conversions as structural projects. An agricultural building was built for a different purpose and a different load.
  5. Check the designation. The core has traditional character; requirements vary across the village.

Questions people actually ask

Can I rebuild a collapsed terrace wall in concrete?

You can, and it is usually the wrong answer. A dry stone wall drains through itself; a rendered concrete one dams the water behind it. That is how a stable terrace becomes an unstable one.

Can an old agricultural building be converted to a house?

Frequently yes, subject to permits, and it is a structural project rather than a cosmetic one. These buildings were built for storage and animals, not for the loads and openings a house needs.

Is the east aspect better than a caldera view?

For comfort, arguably — morning sun and shelter from the worst afternoon exposure. For view value it is a different market. Both are legitimate and they suit different owners.

Is access good?

Reasonable through most of the village, which puts it in a much better cost position than the caldera settlements.

Do I need a permit for terracing work?

Above roughly 1.5 m of retained height, or with anything surcharging it, yes. Below that and outside a designated area, frequently not — but the drainage still matters.
