Buying a plot on Karpathos and building your own house is a plan many buyers have. A large part of what is for sale on the island is land. Not every plot can be built on, though, and building has become a lot more expensive in recent years. Below we explain what to check before you buy a plot and what you should budget for the house itself.

This article reflects the situation in October 2026.

At the moment no new building permits are being issued on Karpathos. Since the new rules of 2025 it first has to be settled which land lies inside or outside the village limits and which roads count as official roads, and those rules are still being worked out. A plot that already has a valid building permit can still be built on.

Inside or outside the village?

The first question is where the plot lies. Inside the village limits (εντός σχεδίου) smaller plots can be built on, if they meet the minimum size for that village and have enough frontage on a public road. Outside the village limits (εκτός σχεδίου) a plot generally needs at least 4,000 m² to be buildable.

The rules for villages changed in 2025, and the new village boundaries for Karpathos are not final yet. We explain this in detail in building rules in Karpathos villages.

The forestry office

Forest land can never be built on, whatever its size. In Greece the forestry office (Δασαρχείο) decides whether land counts as forest. A plot outside a village that has been checked by the forestry office, and is still buildable after that check, is worth more than one that has not been checked. Outside the village, at least 4,000 m² of the plot has to be land that is not forest.

Road access

A plot needs frontage on a road that the state officially recognises. A dirt track that everyone uses is not automatically enough. Ask the seller how the plot is reached and have an engineer check whether that road counts.

A building permit

Some plots come with a building permit. That saves you time and gives certainty, because you know what you are allowed to build. Ask until when the permit is valid, how many square metres it allows and whether that can be one house or several buildings. A plot further from the coast can cost €50,000 to €100,000. Close to the sea it gets more expensive. A plot of 4,000 m² at 400 m from the sea, with a building permit for 200 m² and a good view, costs around €250,000.

Water and electricity

Check whether the plot already has a water and electricity connection, or how far away the nearest connection is. Some plots have electricity but no water yet. Connecting a remote plot takes time and costs extra, so ask for this before you agree on a price.

What does building a house cost?

Building has become more expensive all over Greece. Building materials alone went up by almost 12% between October 2021 and October 2022, and prices are still rising. We currently count on around €2,500 per m² for a new house, including the land. Right by the sea, where land is expensive, or with extras such as a pool, aluminium windows and good insulation, it costs more.

Finding builders who can start soon is often the hardest part on the island. When we rebuilt our own house, we worked with an architect from Karpathos who lives and works in Athens and brought builders over from Athens. That cost extra, but they took our house down and rebuilt it in three and a half months. The insulation we had done by a local team, and that alone took more than four weeks, because they worked on several jobs at the same time.

On an island, building costs more than on the mainland, because a lot of material and many builders come by ferry. To build in Greece you need an architect or engineer for the permits. Contact details of architects and builders on the island are on our resources page.

Checklist before you buy a plot

• Inside or outside the village limits, and in which zone?
• Size of the plot and frontage on a recognised public road
• Checked by the forestry office, and still buildable after the check?
• Building permit: issued or applied for, valid until when, how many m²?
• Water and electricity: connected, or how far away?
• Is the asking price the full price?

You find plots for sale on our properties page. Sellers on Karpathos Houses answer most of these questions in their listing. How the purchase itself works is explained in how to buy property on Karpathos.

Frequently asked questions

How big does a plot on Karpathos need to be to build on?

Outside the village limits, in most cases at least 4,000 m² that is not forest land, with frontage on a recognised road. Inside a village the minimum depends on the village and can be much smaller.

What does it cost to build a house on Karpathos?

We currently count on around €2,500 per m² including the land. By the sea, or with a pool and luxury finishes, it costs more.

Do I need an architect to build in Greece?

Yes. For a building permit you need an architect or engineer who prepares the plans and the application.

Is a plot with a building permit worth more?

Yes. With a valid permit you know what you can build and you save time. Check until when the permit is valid.
