Buying a resale property in Lagos and reworking it to your own specification is a familiar route for overseas buyers. British and Dutch buyers in particular take on older townhouses in the centre and dated villas along the coast, drawn by the chance to shape a home rather than accept someone else’s finish. The sums only hold when the renovation budget is understood before the offer goes in. What follows is our reading of what a project realistically costs across the western Algarve in 2026.
1. Why Renovation Appeals to Lagos Buyers
Renovation stock in Lagos ranges from 1960s and 1970s apartments near the marina to stone cottages in the villages behind the coast. The appeal is consistent across nationalities, even where the motive differs. The economics sit close to the wider new build vs resale question that shapes the Lagos market, because a well-run refurbishment can land below the price of a comparable new development.
- British buyers chasing a period townhouse in the historic centre
- Dutch buyers reworking a coastal apartment for year-round use
- German buyers upgrading the energy performance of an older villa
- American buyers arriving on new direct routes and wanting a finished home without a developer premium
2. What Renovation Costs Per Square Metre in 2026
Renovation is priced per square metre of floor area, and the range is wide. Contractors across the Algarve quote broadly along three tiers this year.
- A cosmetic refresh with new paint, flooring and light fittings at roughly €500 to €800 per square metre
- A standard renovation with rewiring, replumbing and quality finishes at roughly €800 to €1,100 per square metre
- A premium rebuild with designer materials and integrated systems at roughly €1,100 to €1,500 per square metre
On a 120 square metre apartment that spread runs from around €60,000 for a light refresh to €180,000 for a full premium rebuild. Structural work, roof repairs and moving walls sit outside these figures and are costed separately, which is where an old building can surprise an owner.
3. Kitchens, Bathrooms and Pools
A handful of line items account for most of the variation in a Lagos quote. They also overrun most often, usually because the specification creeps upward once the work is under way.
- A new kitchen between €5,000 and €25,000, with cabinetry taking around 40 per cent of the budget
- A bathroom between €3,000 for a refresh and €15,000 for a spa specification
- A standard concrete pool between €15,000 and €25,000, with infinity designs reaching €30,000 to €40,000
- Interior painting from €4 to €12 per square metre and exterior work from €8 to €18
4. Permits and the Reduced VAT Rule
Works in Lagos need municipal authorisation, and the route depends on how far the project goes. Lighter jobs run through a prior notice, the comunicacao previa, while structural change needs a full licence from the camara. Municipal fees are modest against the build cost, but the paperwork sets the timeline.
- A prior notice for lighter works at roughly €200 to €500 in municipal fees
- A full building licence for structural change at roughly €1,000 to €2,000
Labour and materials normally carry the standard 23 per cent IVA. Works on buildings inside a delimited urban rehabilitation area qualify for a reduced 6 per cent rate, and Lagos has designated roughly 50 hectares of its historic centre as such a zone. Sitting inside that designated area is enough for the works to qualify, which widens the number of central Lagos properties that benefit and can shave several thousand Euros off a refurbishment invoice.
5. Timelines and Living Around the Work
On-site duration is only part of the calendar. Permitting, material lead times and the summer slowdown, when many Algarve trades are stretched, push the real programme longer than the raw build window suggests.
- A kitchen in two to four weeks on site
- A bathroom in two to three weeks
- A full apartment in four to eight weeks
- A full villa in eight to sixteen weeks
Most overseas owners budget for a project running across two seasons rather than one, and they plan for a spell when the property is not habitable. British and German buyers who intend to use the home over the following summer generally start work in the autumn.
6. Adding the Purchase Price to the Sums
Renovation only makes sense against the entry price. Lagos sits among the more expensive markets in the Algarve, with idealista price data putting the median asking price at roughly €4,500 to €4,600 per square metre in 2026 and coastal stock spreading far wider. Buyers browsing lagos property for sale should read a dated asking price as the start of the sum rather than the finish.
- Purchase price plus acquisition costs, roughly 8 to 10 per cent for a resident buyer, covering progressive IMT, the 0.8 per cent stamp duty and legal fees
- A steeper bill for most overseas buyers, since from 1 September 2026 non-residents pay a flat 7.5 per cent IMT on the whole price, with escrituras before that date on the old progressive scale and the flat rate reclaimable if the buyer becomes resident within two years or lets the property out
- Renovation at the per square metre tier the property actually needs
- A contingency of around 10 to 15 per cent for the faults older buildings hide
A resale bought at a discount and renovated to a high standard can still finish below the price of an equivalent new build, which is why the route holds across British, Dutch, German and American buyers alike.
The Reality of Renovating in Lagos
Renovation in Lagos rewards buyers who cost the whole project before they commit, and it exposes those who fix on the purchase price alone. The building fabric, the permitting route and the VAT position on a central property all move the final figure, sometimes by tens of thousands of Euros. A realistic budget pairs the per square metre tier with a genuine contingency and a calendar measured in seasons.
We guide buyers through this at the offer stage, reading the condition of a property against local build costs and pricing the work before an offer is made. That assessment is where a renovation project in Lagos either stands up or quietly falls apart.
