How much does a complete apartment renovation cost?

Expect between CHF 800 and 1,800 per m2 for a complete renovation, i.e. CHF 80,000 to 180,000 for a 4-room apartment of 100 m2. A partial renovation (painting, floors, one wet room) costs between CHF 400 and 900 per m2. The level of finish and structural changes affect the budget.

How long does a complete renovation take?

For an apartment, allow 2 to 4 months on site. For a detached house, 4 to 8 months depending on the extent of work on the envelope. Add the time to obtain a building permit if required, generally 2 to 4 months in Western Switzerland.

Do I need a building permit to renovate?

An interior renovation without structural changes generally does not require one. However, work on facades, windows or the roof, or extending the building, requires a permit. Rules vary by canton and municipality: your contractor will guide you through the process.

Is an asbestos survey mandatory?

Yes: for any building constructed before 1991, an asbestos survey is mandatory before renovation or demolition work. If asbestos is found, removal must be carried out by a recognised company. Allow for this item in your budget and schedule.

Can you live in the home during the work?

For a complete renovation, it is strongly discouraged: dust, noise, water and power cuts make daily life difficult and slow down the work. Room-by-room phasing is sometimes possible for partial work. Budget for transitional accommodation.

Complete apartment renovation: rethinking your interior

Fully renovating an apartment means rethinking volumes, circulation and light. Our partners handle every aspect: removing partition walls, new room layouts, electrical work to OIBT standards, plumbing, screed and floor coverings, kitchen, bathroom, interior carpentry and painting. An apartment from the 1970s or 1980s is brought up to today's standard, with a substantial gain in value.

House renovation: envelope, systems and interior

A house adds the dimension of the envelope: roof, facades, windows and insulation join the programme, alongside heating and interior design. The right approach is to deal first with the envelope and the systems (heating, electricity, plumbing), then the finishes. Our general contractors establish a precise phasing that avoids doing the same work twice and makes the most of every franc invested.

Energy renovation: insulate, heat, add value

A complete renovation is the ideal moment for the energy transition: envelope insulation, window replacement, a heat pump instead of oil heating, even solar panels. A CECB+ audit identifies priorities and quantifies the expected savings. Subsidies from the Buildings Programme and the cantons of Western Switzerland significantly reduce the bill, and an efficient home sells or rents better.

What influences the price of a complete renovation

The surface area and scope of work set the order of magnitude: a light renovation (painting, floors, refresh) costs between CHF 400 and 900 per m2, a complete renovation between CHF 800 and 1,800 per m2, and a heavy transformation with structural work can exceed CHF 3,000 per m2.

The year of construction plays a decisive role: buildings predating 1991 require an asbestos survey, and old installations (electricity, pipes) often need to be entirely replaced. Structural changes, load-bearing walls, openings, extensions, require an engineer and a permit.

In Western Switzerland, prices vary by canton and site accessibility. To frame your budget, compare up to 3 free quotes via Edirex.

Permits, asbestos and subsidies in Western Switzerland

Work affecting the structure, facades or use of the building requires a building permit, issued by the municipality under cantonal legislation. Allow 2 to 4 months for the procedure; contracts are generally based on the SIA 118 standard for execution conditions.

For any building constructed before 1991, an asbestos survey is mandatory before work begins. This step protects workers and occupants, and must be included in your schedule.

On the financing side, the Buildings Programme and cantonal programmes (VD, GE, VS, FR, NE, JU) subsidise insulation and the replacement of fossil-fuel heating. Maintenance work is also deductible from taxable income in most cantons: an argument often underestimated in profitability calculations.

General contractor or separate craftsmen: how to choose

A general contractor offers a single contact who manages all trades, an overall price and clear liability in case of defects. It is the most stress-free option for a complete renovation, at the cost of a coordination margin.

Hiring craftsmen separately can cost less, but requires time and skills: coordinating interventions, managing interfaces between trades, tracking warranties. This route suits simple projects or experienced clients.

With Edirex, every partner company is verified against 4 strict criteria: solvency, liability insurance, social charges up to date and commercial register extract. You receive a maximum of 3 comparable quotes to choose with confidence.
