The sea view that comes with a setback

Why a “beachfront” plot can be the one place you’re not allowed to build.

The view is doing a lot of work in a Greek coastal listing. What it rarely shows you is the αιγιαλός (the foreshore) and the line it draws across your plans.

What αιγιαλός actually is

The αιγιαλός is the strip the sea reaches in its largest ordinary winter swell. By law it is public domain: it cannot be owned, sold or built on. Just inland sits the παραλία, a zone the State may reserve to give public access to the shore. A committee delimits both and the line is published in the government gazette.

Why it bites buyers

Two problems recur. First, a plot sold as “on the sea” may include, or sit right behind, land that is public domain, so the buildable part is smaller and further back than the photos imply. Second, in many areas the line has only been provisionally set, or not set at all, which leaves the eventual setback uncertain at exactly the moment you’re asked to commit.

Existing buildings close to the water aren’t reassurance either: some predate the rules, some were licensed under since-changed conditions, and some are simply unlawful and at risk.

What to check before you fall in love

None of this means a coastal plot is a bad buy. It means the sea view and the buildable footprint are two different questions, and only one of them is on the listing.

Reading about the risk is free. Measuring it is £99 (€115).

The AVLI Risk Snapshot ranks these themes for your exact plot and, where your papers and location allow, runs preliminary checks no listing will: the out-of-plan arithmetic, the deed-against-survey cross-check, the measured distance to the shore.
