Restoring a stone house in Greece: costs, permits and contractor pitfalls (2026)

Our guide to abandoned stone houses in Greece covers where the ruins are and what they cost to buy. This one covers the second bill: the restoration itself, the permits it needs, and the mistakes that most often blow a budget. Figures below are rough benchmarks from published guides dated 2024 to 2026, not quotes, and a stone house under heritage rules is not an ordinary renovation.

What restoration realistically costs

We did not find a published per-square-metre price for restoring a traditional Greek stone house under heritage supervision, so any single number you see is an estimate. General renovation guides give these ranges:

• A standard turnkey renovation on the mainland: about EUR 1,000 to 1,600 per m².
• Islands and remote villages: up to about EUR 2,000 per m² or more, because materials and crews have to be shipped and housed. One guide puts the island premium at roughly 15% to 40%.
• Structural work alone (roof, walls, floors) is quoted at about EUR 600 to 1,500 per m², before kitchens, bathrooms, wiring and plumbing.
• Architect, engineer and permit fees: roughly 8% to 15% of the construction budget.

Two things push a stone house above these ranges. First, a roofless ruin needs a new roof, new floors and often rebuilt walls before anything else, and the stone itself must be matched or recovered. Second, materials have been volatile: a Greek technical-office head quoted in 2024 said construction material prices had risen by more than half in a short period. Treat the numbers above as a way to sanity-check quotes, not to replace them. A realistic plan is a purchase price plus a renovation budget that can equal or exceed it, plus a reserve of 15% to 20% for surprises in old masonry.

Which permit you need

Works in Greece go through a national electronic permitting system used by engineers (often called e-Adeies, run through the Technical Chamber of Greece). In broad terms:

• A full building permit is needed for new construction, extensions and structural changes that affect the stability of the building. One summary says processing generally takes up to about 45 working days once the file is complete. Incomplete files restart the clock.
• A lighter, small-scale permit route exists for works that do not touch the structure or increase the volume, such as interior finishes.
• A restoration of a ruin usually involves structure, so plan on the full route and on a licensed architect or civil engineer who submits it and supervises the works. In Greece it is the engineer, not the contractor, who is legally responsible for the file.

Before you pay for drawings, ask the engineer to check the building's legal status in the cadastre and in the local planning office (YDOM). A stone house that was never registered, or that sits on land with building restrictions, can stall the permit for months. The same checks are covered in our guide on title checks for inherited village houses.

Listed buildings and traditional settlements

Many stone villages in Pelion, Epirus and elsewhere are officially protected as traditional settlements, and individual buildings can be listed. The practical consequences:

• Plans may need approval from a heritage body on top of the ordinary permit: usually the regional Ephorate of Antiquities or the local Architectural Council, depending on the status of the village or the building.
• Rules typically dictate materials and form: local stone, timber windows, slate or traditional tile roofs, and the original volume and openings. Modern extensions are usually restricted or refused.
• Strictness depends on the designation. In a 2024 ruling on Hydra, Greece's Council of State held that the island's monumental designation prevails over the more permissive traditional-settlement rules and allowed only the reconstruction of a similar building whose existence could be proven. That is one case, not a national rule, but it shows why the status of your village matters before you buy.
• A damaged listed building is generally rebuilt from documentation of its original form, so photographs, old plans and the engineer's survey become part of the application.

We could not confirm a single national sequence or timeline for these approvals, and we found nothing specific to Mani. Ask the engineer and the regional Ephorate for the status of the exact building before signing a purchase contract, and keep a clause that lets you walk away if the designation makes your plans impossible.

VAT, taxes and subsidies

Greece's standard VAT rate is 24%, with reduced rates of 13% and 6%. Which rate applies to a given restoration or masonry invoice depends on the type of work, and for listed buildings an older press report said a reduced rate on materials and works still applied. We could not confirm the current rule, so do not assume a reduced rate: ask your accountant to confirm the rate for each line of the contract before you sign.

The 24% VAT suspension that Greece extended to the end of 2026 applies to sales of certain new homes by developers. It does not apply to your contractor's invoices.

A renovation subsidy programme for older homes was reported in 2026 by at least one secondary source. We could not confirm that it is open, or whether it is open to non-residents, so do not build your budget around it. Check with an engineer or the managing authority. If you plan to rent the finished house, see the rules in our guide to short-term rental in Greece.

Contractor pitfalls

• Ask for a written scope and an itemised quote: labour, materials, VAT rate and the contractor's tax number. Compare at least three quotes for the same drawings.
• Pay in stages tied to finished work that the engineer has inspected, not on a calendar. Avoid large advances.
• Do not let works start before the permit is issued. Unpermitted work in a protected village can be stopped, fined or ordered undone.
• Skilled stone masons are scarce and booked months ahead in popular areas. Agree start dates and a completion window in writing, with a sensible penalty for delay.
• Plan for the season. Village roads, water, power and winter weather all slow work, and a roof left open through winter damages old masonry fast.
• Keep the engineer's final certificate and all invoices: you will need them for the legal status of the house, for any future sale and for rental registration.
