Renovating a Neuchâtel home without getting the priorities wrong
In short
A practical guide to working with an interior designer Neuchâtel: the real role, the project phases, the fees (15 to 22 % on renovations, 120 to 300 CHF per hour) and the constraints specific to the canton, from an old yellow-stone building stock to the UNESCO watchmaking quarters of La Chaux-de-Fonds and Le Locle.
In Neuchâtel, many homes are over a century old. Behind a yellow-stone façade, inside a maison de maître on the Faubourg de l'Hôpital or in a building of the watchmaking quarter, a layout that looked fixed often hides unexpected room to manoeuvre. You just have to read the fabric of the building before the first partition goes up.
A profession of space, not decoration
An interior architect organises space: circulation, light, volumes, storage, services. It is structural work that begins long before the choice of materials and colours. It should not be confused with a decorator, who dresses an existing space, nor with an ETH/EPF architect, the only professional qualified for the envelope and load-bearing structure of a new building.
- Survey of the existing space and diagnosis of constraints (load-bearing walls, ducts, ceiling heights)
- Design of the layout and volumes, with costed variants
- Selection of materials, lighting and technical installations
- Construction dossier and bespoke joinery details
- Coordination of trades and site supervision through to handover
An old building stock and a yellow stone to respect
The canton has a high share of old buildings, often predating 1950. The yellow stone of Hauterive, which earns the city of Neuchâtel its nickname of the « yellow city », clads the façades, staircases and surrounds of many maisons de maître. These elements are frequently listed in the heritage inventory: you renovate the interior, but you touch neither the façade nor the openings without a permit.
In the lakeside wine villages, from Auvernier to Cortaillod or Boudry, the same logic applies to old volumes and cellars. An old building also holds surprises: out-of-square floors, missing insulation, ageing services. A serious survey up front keeps such discoveries from blowing up the budget mid-project.
La Chaux-de-Fonds and Le Locle: the UNESCO framework
La Chaux-de-Fonds and Le Locle have been UNESCO World Heritage sites since 2009 under the heading of « watchmaking town planning ». The plan of parallel strips, the façades and the internal typology of the buildings bear witness to the organisation of watchmaking work, with large north-facing windows to capture the light. Façades and the urban structure are strongly protected; depending on the case, certain interior elements are too. Before any project within this perimeter, consult the relevant municipal service — the rules differ from one building to the next and deserve a case-by-case check.
In a watchmaking building, the first question is not « which style ? » but « what can we touch ? ». The answer shapes everything else in the project.
The phases of a project, from sketch to site
Measurements, building diagnosis, definition of needs and a realistic budget envelope.
Plans, layout variants and a first cost estimate so decisions come before the spending.
Final plans, technical details and, where needed, a building application or heritage opinion.
Consulting the trades, comparing quotes and awarding the works.
Site management, coordination of trades, quality control and final acceptance.

What an interior designer Neuchâtel costs
Fees are calculated as a percentage of the construction cost or by time spent. On a renovation, expect around 15 to 22 % of the works; for a fit-out in a new build, 12 to 18 %. The hourly rate is most often between 120 and 300 CHF depending on experience and complexity. The SIA standards serve as a benchmark, but their fee scales have no longer been binding since 2020: everything is negotiable and must be set out clearly in the contract.
Indicative ranges by project type
On an old building, set aside a reserve of 10 to 20 % for the unexpected. Without serious management, overruns commonly reach 15 to 25 %. A Neuchâtel word of caution: any building constructed before 1991 may contain asbestos (tile adhesives, floor tiles, sealants). A survey before demolition is essential and its cost must be anticipated.
Renovating an old property or building new
- Character, ceiling heights and original materials
- Central locations, often near the lake or the centre
- Heritage constraints and possible technical surprises
- Higher fees (15 to 22 %) because every detail is bespoke
- Energy performance and freer layouts
- Fewer structural surprises, a more predictable site
- Less character, standardised volumes
- Lower fees (12 to 18 %) and better-controlled timelines
When to call in a professional
Not every project justifies a full mandate. But as soon as you move a partition, touch a protected property or coordinate several trades, professional support quickly pays for itself — through the mistakes avoided and the quotes better negotiated.
- Redistributing rooms or opening up a living space
- Renovation in a listed building or a UNESCO zone
- A project combining kitchen, bathrooms and services
- An old building with an uncertain diagnosis (asbestos, services)
- A tight budget to optimise without sacrificing quality

Describe my projectFAQ
An interior architect designs the organisation of space: distribution, volumes, light, services and bespoke joinery. A decorator works on the atmosphere of an existing space (furniture, colours, textiles) without touching the structure or the plans.
On a renovation, fees generally represent 15 to 22 % of the construction cost, against 12 to 18 % for a fit-out in a new build. The hourly rate is most often 120 to 300 CHF. Since 2020, SIA fee scales are no longer binding: everything is negotiable and should be set in the contract.
Not always. Both towns are UNESCO-listed under watchmaking town planning, with strong protection of façades and the urban structure, and sometimes of certain interior elements. You must consult the relevant municipal service before any project, as the rules differ from one building to the next.
Yes, for any building constructed before 1991. Asbestos hides in tile adhesives, floor tiles or sealants. A survey before demolition is mandatory and its cost must be built into the budget from the outset.
Allow a reserve of 10 to 20 % of the budget. On a poorly known old building, overruns often reach 15 to 25 % without a serious upfront survey and rigorous site management.
