Cost of an Apartment Renovation in Neuilly-sur-Seine in 2026

The price per sqm of a renovation in Neuilly

Every project is different: it is the starting condition and the chosen level of finish that drive the figure, not just the floor area.

What pushes the cost up (or down)

Three items carry the most weight: electrics and plumbing (if everything needs bringing up to code, this is a significant budget line), the kitchen and bathrooms (the most expensive rooms per sqm), and the chosen level of finish (entry-level tiling and marble are worlds apart in price).

In Neuilly, local constraints add to this: strict co-ownership rules, regulated working hours, and sometimes a cramped lift that complicates rubble removal. These factors don't blow the budget, but they should be anticipated from the quote stage to avoid unpleasant surprises.

How long does the project take?

For a full apartment renovation in Neuilly, allow on average 8 to 14 weeks depending on the floor area and number of trades involved. A partial renovation (a kitchen or bathroom alone) is completed in 2 to 4 weeks.

At LUPOQ Rénovation, the schedule is provided before work begins and held to contractually — so you know exactly when you get your keys back.

How to get a fair price

The only reliable price is one established after a site visit. Be wary of quotes given over the phone: a Haussmann-era apartment with mouldings to restore and a recently built apartment are not comparable at all. LUPOQ Rénovation visits free of charge in Neuilly, draws up a detailed, itemized quote, and fixes it contractually before work begins.

Why Neuilly is not simply Paris with a different postcode

Neuilly-sur-Seine sits immediately west of the Bois de Boulogne and its housing stock is a mix that Paris does not have in the same proportions: late nineteenth-century buildings comparable to Paris, a substantial 1930s stock with generous volumes, and post-war blocks. Each behaves differently once the walls are open.

The 1930s buildings in particular are often reinforced concrete rather than timber joists, which changes almost everything: the floors are stiffer and take underfloor heating better, the partitions are frequently hollow terracotta rather than plaster, and the service risers are laid out differently. A quotation copied from a Haussmann apartment does not translate.

What drives the cost here

The variables are the same everywhere and their weight is different. In Neuilly the recurring ones are the age of the electrical installation, whether the plumbing has ever been renewed from the riser, the standard of finish expected in the area, and access.

Access matters more than people expect. Many Neuilly buildings have narrow lifts or none, restricted parking for deliveries, and building rules that limit noisy work to a short daily window. Each of those extends the programme, and time on site is a cost line whatever the finish.

Co-ownership rules and the general assembly

Work touching load-bearing elements, common pipework, the façade or the building's structure needs authorisation from the assembly of co-owners, which meets on its own schedule. In practice this is the item that most often delays a Neuilly project, because owners assume it is a formality and discover it is a vote.

The survey establishes early which parts of the scope require authorisation, so that the request goes in ahead of the programme rather than interrupting it.

How the quotation is built

No figure is quoted before the apartment has been seen. The survey opens up what needs opening, establishes the state of the concealed services and the floors, and produces a scope. The quotation then prices that scope line by line, and the price is contractual before signature.

Where the state of something cannot be established without demolition, it is identified as such rather than buried in a provisional sum, so that the owner knows in advance which item could move and why.

Reading a quotation properly

A quotation that fits on one page is not a simplification, it is a lack of detail that will be resolved later at your expense. What a serious document shows: the demolition and disposal separated from the construction, the electrical installation described by circuit rather than by room, the plumbing described from the riser rather than from the visible fittings, the floor build-up specified including the levelling, and the finishes named by product reference.

Where an item cannot be established without opening up, it should say so explicitly. Ambiguity in a quotation always resolves in favour of the person who wrote it.

Working with an owner who is abroad

Most renovations in Neuilly commissioned by foreign owners run without the owner present for most of the programme. That works when three things are set up at the start: a single named contact rather than a general line, reporting at the milestones where a decision becomes irreversible, and a written rule about what the site may decide alone and what must wait for you.

Handover is the one stage worth travelling for. An hour walking the apartment with the site manager, list in hand, catches what no photograph shows, and the signed list is what the one-year guarantee attaches to.

What we survey before quoting

Five checks, carried out in a single visit, remove most of the uncertainty. We open the consumer unit and count the circuits: a board with rewireable fuses, a missing earth or undersized conductors call for a full rewire, not a partial upgrade.

We sound at least one point of the floor. In the older buildings along boulevard d’Inkermann the floors are timber joists, which limits the load they accept and determines whether a traditional screed is possible at all.

We locate the soil stack and measure the height available beneath the finished floor. A gravity drain needs a steady fall of one to three centimetres per metre: this measurement, not the layout drawing, decides where a kitchen or a shower room can actually go.

We check the nature of every wall to be altered, and we measure the access route from the street to the flat. In the 1960s to 1980s buildings on the Saint-James side, the technical ducts are closed and shared, so the connection point does not move and the room is redrawn around it.
