Buy property in Sardinia: an architect's guide to choosing the coast
Buy property in Sardinia: six coasts compared, prices read with their sources, the rules on the sea and nine checks before you offer.
Buy property in Sardinia: where to start
Anyone looking to buy property in Sardinia soon sees the same picture thousands of times: a terrace, a turquoise sea, a price. But Sardinia is not one market. Porto Cervo and Bosa are two opposite ways of living by the sea, with rules, climate and costs that change from one shore to the other.
This guide is written by architects and does one thing: it helps you decide which coast suits you and what to check before you make an offer. The second point matters more here than almost anywhere else in Italy, because the regional landscape plan governs the coast with a severity few buyers expect. You will not find listings on this page. This is a technical reading, to use alongside your agent and your notary.
Buy property in Sardinia: the essentials
- The coast comes before the house: Gallura, Alghero, Villasimius and Chia are different purchases, in character and in distance from the airports.
- New building by the sea is tightly limited: the regional landscape plan protects the coastal strip, which gives what already exists a particular value.
- Published figures are maximums: the €21,000/m² of Porto Cervo is an OMI quotation, not the price of a house.
- Three typically Sardinian checks: the coastal strip boundary, civic uses, and the permits of houses built before the plan.
- The mistral sets the running costs: wind and salt wear out materials and systems.

Best places to buy property in Sardinia: the coasts compared
The table sums up the six most sought-after coasts. It is not a ranking. The useful question is not which is the most beautiful but which supports the life you want there, for how many months a year, and how far from an airport and a hospital.
| Coast | Character | What you buy | Check first |
|---|---|---|---|
| Costa Smeralda and eastern Gallura | Porto Cervo, Baja Sardinia, Porto Rotondo, close to Olbia airport | Villas on granite, houses in planned villages, serviced residences | Consorzio membership, building permits, future views, running costs |
| Northern Gallura | Santa Teresa, Capo Testa, Palau, facing Corsica and the Maddalena islands | Granite houses, stazzi to restore, villas on the sea | Mistral wind, access roads, coastal strip, state of the walls |
| Coral Riviera and Bosa | Alghero’s Catalan old town, Bosa on the River Temo, the west coast | Old-town houses, villas in pine woods or on the headland | Historic-centre rules, western exposure, salt |
| South-east: Villasimius and Costa Rei | Long pale beaches, about an hour by road from Cagliari | Holiday villas, recent complexes, houses with gardens | Subdivision agreements, dunes and lagoons, water supply |
| South-west: Pula and Chia | Dunes, coastal towers, archaeological sites, near Cagliari | Villas in private estates and country houses | Archaeological limits, protected areas, winter services |
| Gulf of Orosei and Ogliastra | Cliffs, mountains on the sea, a smaller market | Village houses and isolated villas, little high-end supply | Roads, hydrogeological risk, civic uses |

Costa Smeralda: a designed landscape
The Costa Smeralda is less a place than a work of architecture. From 1962 an almost uninhabited stretch of coast between Arzachena and Olbia became a settlement with shared rules: a consortium, an architecture committee, a recognisable language. Buyers who want the most services and the most international market start here, and pay for it. The next section explains what it means to buy inside this system.
Santa Teresa and Capo Testa: granite and wind
Further north, Gallura turns drier. Granite breaks through the ground, the wind is more present, and Corsica appears on clear days. You can still find stazzi, the old rural houses of Gallura, alongside villas built in local stone. This is a choice for those who want silence and landscape more than social life. The season is shorter, and on mistral days the sea asks for respect: how a plot is exposed matters as much as what it looks at.

Alghero and Bosa: living in a town on the sea
On the west coast, value does not lie only in the isolated villa. Alghero has a Catalan-influenced old town enclosed by sea walls and stays alive in winter, with an airport a short drive away. Bosa, on the River Temo, is among the island’s loveliest small towns. Those planning to stay for many months often look here. The checks concern old-town restrictions and the afternoon sun, which comes in low and strong on west-facing facades.
Villasimius, Costa Rei and Chia: the south
The south has long pale beaches, lagoons, coastal towers and a longer season. Cagliari is a real city, with hospitals, a university and year-round connections, an advantage people underrate when they plan to live on the island. Many houses here belong to subdivisions and private estates, so read the agreements, rules and shared costs. Around dunes, lagoons and archaeological areas the room for change is narrow.
Buying on the Costa Smeralda: the Consorzio and its architecture
The Consorzio Costa Smeralda was founded in 1962, with Prince Karim Aga Khan among its first members. At its core was an architecture committee that controlled every building project in the area. According to Domus, its members included Luigi Vietti, Jacques Couelle, Michele Busiri Vici and Antonio Simon Mossa. That is where the style we know comes from: simple volumes, repeated arches, pale or pastel plaster, stone and planting brought right up to the house. It was an invented style, as the sources themselves say, but built with great care for materials.
For a buyer the consequences are practical. Before you offer, ask whether the property belongs to the Consorzio, which architectural rules apply, which annual contributions are due and who must approve an external change. These are questions for the seller and the Consorzio’s offices: we found no current published regulations or fees, so we do not quote them here. A shared rule is also a protection, because it holds together the landscape you are paying for.

What it costs to buy property in Sardinia
There is no reliable average price for villas on the island, and the numbers in circulation are almost always maximums. These are the most recent figures we have read:
| Figure | Value | What it measures |
|---|---|---|
| Porto Cervo, villas | €21,000/m² | Maximum OMI quotation, first half of 2026: the highest in Italy for villas |
| Portofino, villas | €19,000/m² | Maximum OMI quotation, same period |
| Forte dei Marmi, villas | €17,100/m² | Maximum OMI quotation, same period |
| Porto Cervo and Costa Smeralda, best properties | up to €35,000/m² | Peak values for villas, penthouses and seafront homes, Engel & Völkers with Nomisma, 2026 |
The OMI values come from the Italian Revenue Agency’s property market observatory, as summarised by La Voce di New York on 19 October 2026 (in Italian); the peak figure is from the Market Report Italia 2026 by Engel & Völkers with Nomisma, reported by idealista/news. Read them with care: OMI gives indicative ranges by zone and type, not sale prices, and a zone’s maximum does not apply to every house in it.
A villa with direct sea access or a unique position can stand well above the quotation, a dated house set back from the shore well below it. Away from Porto Cervo the values vary even more, and for much of the island we have no comparable source, so we prefer not to print a number. A real estimate needs the OMI values for the exact zone, closed sales of comparable houses and a surveyor’s opinion. Anyone quoting one price per square metre for a whole coast is offering an impression, not a valuation.

Can you buy cheap property in Sardinia?
Many searches mention cheap houses and one-euro homes. Some inland towns in Italy have run such schemes, each with its own rules and renovation obligations set by the municipality. They are a different market from the one this guide covers: inland, in old centres, with a building site attached. By the sea, and above all in Gallura, the protected coast and limited supply work against bargains.
What buyers are looking for
According to the same report, demand in Porto Cervo and the Costa Smeralda comes mainly from abroad and looks for sea views, gardens, panoramic terraces and houses ready to move into. No sales volumes accompany the statement, so it remains a qualitative description. For an architect it says something useful: a house to renovate, in a place where works are slow and limits are tight, should be negotiated on a different basis from a finished one.
Coastal rules: what to know before you buy property in Sardinia
Few foreign buyers realise how different the island is from the rest of Italy on this point. The Regional Landscape Plan (Piano Paesaggistico Regionale, PPR) stems from regional law 8 of 2004 and treats the coastal strip as a single protected landscape, a «fundamental strategic resource» of the island. Its boundary is drawn on the plan’s maps. It is not a fixed distance, and reports from the time of approval put it at an average of at least two kilometres from the sea.
The implementing rules published by the Region (in Italian) say, among other things, three things. Article 20: in undeveloped areas of the strip any transformation is barred, apart from specific exceptions. Article 19: planning zones A and B are excluded, as are, under conditions, some zones C, D and G with approved implementing plans. Article 12: land within 300 metres of the shoreline, 150 on minor islands, cannot be built on, with stated exclusions.
For existing buildings, the same article 12 allows maintenance, consolidation, renovation and restoration if they do not alter the site, the outer profile, the volume, the use or the number of units. In practice, you can rebuild a house’s interior and fabric; enlarging it or changing its shape is another matter.
One caution. The text we read is the 2006 version. Since then rulings and regional interpretive laws have stepped in several times, and the so-called Piano Casa has been amended and taken before the Constitutional Court. We have not verified an updated consolidated text, so we give no extension percentages: they would probably already be out of date. The right answer comes from the municipality for the specific property, starting from the maps on the regional geoportal.

Why the limits create value
A coast where you cannot build is a coast that stays as it is. That is why Sardinia has kept stretches that have vanished elsewhere, and why an existing house in a good spot is a scarce resource. The other side is that a listing with «extension potential» or «sea-view building plot» deserves great caution. Ask which rule grants that potential and see the permit: the project imagined in the price is often the one that can never be built.
Before you buy property in Sardinia: nine checks
These are the checks we run on Sardinian houses, in the order we run them:
- Which planning zone the house sits in. Ask the municipality for the certificate of planning use and read the current plan. This decides whether the house is inside or outside the protected «coastal strip», and what can be done to it later.
- Whether the landscape plan’s boundary touches it. The coastal strip is drawn on maps; you cannot work it out from the distance to the sea. Check it on the regional geoportal and then with a surveyor on site.
- Whether what you see matches the permits. Verandas, pools, pergolas, annexes and closed terraces were often added after the original project. Read any amnesty file through to its conclusion: knowing it was filed is not enough.
- Whether the land carries civic uses. This is a real check in Sardinia. Collective lands are governed by regional law 12/1994 and the landscape plan treats them as protected assets. Ask the municipality and the regional offices before you offer, not after.
- Whether the villa depends on the sea or the public shore. Jetties, moorings, private beach access and works on the shoreline have their own permits with expiry dates. Ask for the document: the view in the price does not include the use of the sea.
- How water, drainage and power arrive. Outside town centres many houses have their own systems. Ask where the water comes from, how treatment works, and what happens in August when everyone is there.
- How the house stands up to wind and salt. The mistral is the island’s design brief. Look at hardware, window frames, railings and plaster, and ask when they were last renewed. Corrosion is the true cost of a house on the sea.
- How it is protected from fire. A villa in the maquis needs cleared margins, access for vehicles and available water. Municipalities keep a register of burnt areas: check it for neighbouring land too.
- Who looks after it from October to May. A house closed for seven months wears out. Gardener, caretaker, pool and systems maintenance belong in the budget before you decide what to pay.

Can foreigners buy property in Sardinia? Taxes and rules
Sardinia has no special rules on who can buy or on purchase taxes. EU and EEA citizens face no limits. Others buy under the reciprocity condition verified by the notary, unless a treaty applies or they live in Italy on a valid permit. You need an Italian tax code to sign. The table shows the figures from the Revenue Agency (in Italian) without «first home» relief:
| You buy from | Registration tax | VAT | Mortgage tax | Cadastral tax |
|---|---|---|---|---|
| Private seller or VAT-exempt company | 9% (minimum €1,000) | — | €50 | €50 |
| Company with VAT, ordinary home | €200 | 10% | €200 | €200 |
| Company with VAT, categories A/1, A/8, A/9 | €200 | 22% | €200 | €200 |
«First home» relief does not apply to categories A/1, A/8 and A/9, and a house called a villa in a listing may belong to a different category from the one you expect. The full sequence, from written offer to final deed, is explained in our guide buy a villa in Italy.
Getting there and staying: airports and seasons
The island has three gateways: Olbia for Gallura, Alghero for the north-west, Cagliari for the south. Olbia has grown fast: a table carried by TravelNoStop shows more than 4 million passengers in 2025, against 3.3 million in 2023. Since 20 May 2026 Delta has linked New York JFK and Olbia with four direct flights a week, according to QN, a sign of how the season is stretching. Still, check the January flights, not the August ones: winter is when you really measure how far a house is from your life.
Arriving by sea gives a different view: our guide to yacht charter in Sardinia covers the island’s routes, and it is a good way to see the coasts before choosing. If you want a property to run as a hospitality business, read Sardinia resort for sale.

An architect's reading: how to live with granite
A good Sardinian house shows in how it handles wind and light. A patio sheltered from the mistral is worth more than an exposed terrace you use a few days a year. Deep shade counts for more than glass: large unprotected windows facing south and west make a house unliveable in July. A wall of local granite stands up to salt and ages well, while pale plaster needs regular care. For materials, see natural stone and luxury pools.
The house should rest on the ground without forcing it. Rock outcrops are both a limit and a resource: in the best houses they enter the garden, sometimes the living room. Keep as much maquis as you can, because it shelters from the wind and grows slowly; an English lawn in Gallura is a water bill and a landscape mistake. This is what we do in the preliminary reading: a written opinion on what the house shows, what is missing and what must be verified.
If you plan to transform an existing house, measure the real margin first with a professional who knows the municipality. The architect Federico Cappellina, founder of ELRE, leads a studio designing contemporary villas; it is a separate activity, with its own client appointments. For professional costs there is the guide to architect fees for a villa in Italy, and for a bespoke project the page Signature Architecture.
How we read the market: the ELRE method
Every assessment goes through three checks, always in the same order: an architectural reading of the project, a check on site by people who work in that market, a comparison with declared sources. The real estate work is done by the Real Estate team; the founder guarantees the method, described in The method. When we hold properties with a mandate you will find them in the selection of villas for sale; we propose none in this guide.
Buy property in Sardinia: frequently asked questions
How much does a villa in Sardinia cost?
It depends on the coast and the position, and there is no reliable average. The most quoted reference is the maximum OMI value for Porto Cervo, €21,000 per square metre in the first half of 2026, which is a zone maximum, not a sale price. An estimate needs comparable sales and a surveyor.
What is the best place to buy property in Sardinia?
It depends on how you will live there. The Costa Smeralda for services and an international market, Santa Teresa for landscape, Alghero and Cagliari for long stays near a city, Villasimius and Chia for the southern sea. The table of coasts sums up the differences.
Can foreigners buy property in Sardinia?
Yes, under the same rules as the rest of Italy. EU citizens face no limits; others buy under reciprocity verified by the notary, unless a treaty or a valid residence permit applies. You need an Italian tax code.
Can you build a villa by the sea in Sardinia?
As a rule, only with great difficulty. The landscape plan’s rules bar transformation in undeveloped parts of the coastal strip, apart from exceptions and excluded zones, and declare land within 300 metres of the shoreline unbuildable, with some exclusions. Each plot must be verified with the municipality.
What is Sardinia's coastal strip?
It is the protected landscape that covers the Sardinian coast. It is not a fixed distance: the boundary is drawn on the plan’s maps and can be checked on the regional geoportal.
Can you extend a villa in Sardinia?
It depends on zone, restrictions and current rules, which have changed several times. The plan allows renovation that does not alter volume and profile; extensions follow specific rules. Ask the municipality about the specific property before you offer.
What are civic uses?
They are collective rights of a community over certain land. In Sardinia they are governed by regional law 12/1994, and the landscape plan treats these areas as protected. Check them before buying land or an isolated house.
What taxes do you pay when you buy property in Sardinia?
The same as the rest of Italy. From a private seller, 9% registration tax, minimum €1,000, plus €50 mortgage tax and €50 cadastral tax. From a company with VAT, 10%, or 22% for categories A/1, A/8 and A/9. Source: Revenue Agency.
Do you need an architect before making an offer?
It is not compulsory, but in Sardinia it is the check that protects you most, because restrictions and permits decide the value. With the preliminary reading we tell you in writing what the house shows and what to verify.
