Building a New Property in Greece

Building a New Property in Greece: Buildability, Permits, Costs, and What Actually Limits You

Building a new property in Greece is never just a construction decision. It is a planning, legal, and regulatory process that starts long before an architect draws the first line. What you can build, how much you can build, and whether a project is even viable depends almost entirely on where the land is classified and what use is legally permitted on it.

Many failed construction projects in Greece are not the result of bad builders or poor design, but of wrong assumptions made at the land stage. This guide explains how new property construction works in Greece using real figures, real limits, and the rules that actually stop projects in practice.

The First Limiting Factor: Land Classification

Before discussing design or cost, land must fall into one of three categories. Each one has different construction outcomes.

Land inside a town plan (entos schediou)

This is the most predictable environment for new construction.

Construction limits are defined by:

building coefficient (Σ.Δ.)
coverage percentage
height limits
zoning use

Typical examples:

Plot 400 m² with Σ.Δ. 0.8 → up to 320 m² total construction
Plot 600 m² with Σ.Δ. 1.0 → up to 600 m² total construction

Coverage usually ranges from 50% to 70%, meaning you cannot build the entire allowance on one floor.

Height is usually:

2 floors in small towns
3–4 floors in cities
depending on zoning.

Inside town plans:

subdivision is usually allowed
infrastructure is assumed
permits are clearer and faster

This is where most multi-unit and predictable residential projects happen.

Land inside settlement boundaries (entos oikismou)

Settlement land allows construction, but under stricter and less flexible rules.

Key characteristics:

minimum plot size often between 300 m² and 2,000 m²
residential allowance usually between 240 m² and 400 m²
height almost always limited to 2 floors
architectural restrictions common

In traditional or protected settlements:

roof type is fixed
façade materials may be regulated
modern designs are often rejected

Settlement land is suitable for:

single houses
low-scale residential use

It is rarely suitable for intensive development.

Land outside town plans (ektos schediou)

Out-of-plan construction is the most limited and misunderstood category.

The standard residential rule:

minimum plot size: 4,000 m²
legal access to a recognized public road is mandatory

If both conditions are met, the typical maximum allowance is:

approximately 186 m² for one residence

Important realities:

larger plots do not scale proportionally
subdivision does not create new rights
setbacks often reduce buildable footprint
approval timelines are longer

Out-of-plan construction is suitable only for buyers who accept strict limits.

Residential vs Hotel Construction (Critical Distinction)

Building a house and building a hotel are governed by different laws.

A plot that allows a residence may be completely illegal for hotel use.

Hotel construction requires:

zoning that explicitly allows tourism use
larger minimum plot sizes
different density calculations
compliance with hotel licensing rules
minimum room sizes and layouts
parking and accessibility compliance

Hotel feasibility must be checked before land purchase. Design cannot fix zoning.

The Building Permit Process for New Construction

New construction always requires a full building permit.

The process includes:

architectural study
structural study
energy performance study
mechanical and electrical studies
topographical survey
land legality verification

Permits are submitted by a licensed engineer through the official electronic system.

Approval time varies:

town plan areas: often a few months
settlements and out-of-plan: longer, especially with additional approvals

Starting construction without a permit creates permanent legal problems.

How Much Does New Construction Cost in Greece

Construction cost depends heavily on:

location
accessibility
quality level
building type

Indicative ranges (excluding land):

basic residential construction: lower range
mid-quality residential: higher range
high-end or custom villas: significantly higher

In addition to construction, owners must budget for:

studies and permits
utility connections
landscaping and external works
unexpected ground or access issues

Most cost overruns come from underestimating non-construction expenses.

Where New Builds Commonly Fail

The most common failure points are:

buying land before confirming buildability
assuming hotel use is possible later
designing beyond legal limits
ignoring settlement or traditional rules
underestimating permit timelines
starting works early

These mistakes are usually irreversible.

Who Must Be Involved From the Start

Successful new construction requires:

civil engineer (planning and permits)
architect (design within legal limits)
topographer
lawyer (land legality)
contractor (after permits, not before)

Skipping early professional checks is the fastest way to stall a project.
