Cost of an Apartment Renovation in Enghien-les-Bains: 2026 Prices and Advice

The price per sqm of a renovation in Enghien-les-Bains

For the Belle Époque villas or early-20th-century houses (1900-1930) commonly found around the lake, costs are often 15 to 25% higher due to the specific materials that need preserving (period parquet, mouldings, millstone or stone façades). LUPOQ Rénovation notably carried out a project on a 1930s house in Enghien, with a listed façade and strict heritage-architect requirements.

What affects the final cost in Enghien-les-Bains

The proximity of the lake and the high property pressure in Enghien-les-Bains create strong demand for high-end renovations. The main variable remains the original condition of the property: a 1970s apartment requiring a full electrical upgrade (to NF C 15-100 standards) will cost considerably more than a home that has already been partially renovated.

The requirements of France's heritage architects (the ABF) are a key factor in Enghien. Certain façades, roofs or architectural features cannot be altered without prior approval, which extends approval timelines and sometimes requires more costly substitute materials. LUPOQ Rénovation supports its clients through these administrative procedures.

Site accessibility also plays a role: buildings without a lift or villas with narrow private courtyards can generate additional logistics costs. Delivering materials through the tree-lined streets around the thermal baths can also extend handling times.

Duration of a renovation project in Enghien-les-Bains

Project duration varies depending on its scope. A partial renovation (a single room, bathroom or kitchen) takes 2 to 4 weeks. A full renovation of a 60 to 80 sqm apartment generally requires 6 to 10 weeks of actual work.

In Enghien, you should factor in the time needed for ABF approvals when the property is affected: the statutory review period can reach 2 months. LUPOQ Rénovation identifies upfront whether your project is subject to these procedures so this can be built into the overall schedule.

For houses with gardens or outbuildings to renovate, seasonality also matters: waterproofing or roof insulation work is best scheduled outside periods of heavy rain.

How to get a fair price for your renovation in Enghien-les-Bains

The best guarantee of a fair price is a detailed, itemized quote drawn up after a visit to the property. LUPOQ Rénovation carries out on-site visits in Enghien-les-Bains and provides accurate quotes that account for local heritage constraints.

Be wary of remote estimates given without a prior visit: the reality of a Belle Époque villa or a lakeside apartment can hold surprises (damp, ornamental ceilings, period flooring). Our in-house teams assess each trade separately for total transparency.

LUPOQ Rénovation is covered by a ten-year structural warranty on all structural work and provides a single point of contact to coordinate the different phases of the project. To request a quote, call 07 68 53 54 13 or use our online form.

A housing stock that is not Parisian

Enghien-les-Bains is a spa town north of Paris and its building stock reflects that history: nineteenth-century villas and townhouses around the lake, early twentieth-century apartment buildings, and later stock further out. The proportion of individual houses is far higher than in Paris, which changes the technical picture entirely.

A house has its own roof, its own façades, its own drainage and often its own heating plant. None of these are shared, which removes the co-ownership constraint but adds scope that a Paris apartment simply does not have.

What drives the cost on this stock

On the older villas the recurring items are the roof, the joinery, the drainage and the thermal performance of the envelope. On the apartment stock the picture is closer to Paris: the state of the electrical and plumbing installations, the floors, and the level of finish.

Two variables carry more weight here than in Paris. First, the presence of a garden and external works, which are frequently underestimated. Second, thermal renovation, because the older detached stock performs poorly and the works to correct it are substantial rather than cosmetic.

Energy performance and what it means for a sale

Since the tightening of the rules on poorly rated housing, the energy label has become a commercial fact rather than a formality. On the older stock around the lake, a poor rating is common and the works to move it are structural: insulation of the envelope, replacement of the joinery, the heating system, and controlled ventilation.

Ventilation is the point most often skipped and the most consequential. Insulating and sealing a house without providing controlled ventilation replaces a draughty house with a damp one, and the mould appears in the second winter.

How the quotation is built

The property is surveyed before any figure is discussed. On a house that means the roof, the drainage and the envelope as well as the interior. The survey produces a defined scope, the scope is priced line by line, and the price is fixed contractually before signature.

Items that cannot be assessed without opening up are identified as such rather than absorbed into a round figure, so that the owner knows in advance what could move.
