Oriels, Stucco and the Abbey District: Rethinking Eastern Swiss Rooms
In short
An interior designer St. Gallen organises the layout, light, materials and furnishing of apartments, villas and commercial spaces in the city and across eastern Switzerland. This guide explains the role, project phases, fees of 15–22 % of the works and the local realities: the old town, painted oriel façades and the cantonal heritage office. Use it to estimate budget, timeline and the right moment to bring someone in.
An apartment in a textile-era townhouse, an oriel overlooking Gallusstrasse, high rooms with stucco – and yet nothing works. The kitchen is too small, the light falls wrong, every alteration runs into the protected façade. This is exactly where professional design that respects the existing fabric earns its place, instead of fighting it.
St. Gallen is no ordinary building site. The city lives between its medieval old town, the lavish villas of the textile era and the demand for contemporary use. Designing an interior here takes more than taste: it takes someone who connects construction, permits and aesthetics.
What an interior designer actually delivers
An interior designer does more than surfaces. They organise space: layout, circulation, daylight, acoustics, materials, lighting and furnishing. They coordinate the trades, review quotes, supervise the site and keep budget and schedule on track. In a protected building they also become the translator between your wishes and the heritage office's requirements.
The difference from a decorator or a kitchen showroom is scope: an interior designer starts with analysis and ends at handover. They think in uses and flows, not in single products. That is decisive in older buildings, where moving a wall has structural and legal consequences.
When you need an interior designer St. Gallen
Not every project needs expert design. For a repaint or a sofa, a good tradesperson is enough. But as soon as you move walls, renovate a Belle Époque villa, touch a listed façade or convert a home into commercial space, things get complex. Bringing someone in early then usually saves more than it costs.
Record the existing fabric, check building substance and protection status, clarify needs and budget.
Layout, material and lighting options, a first cost estimate, feasibility under heritage protection.
Detailed and execution drawings, a building application where work is involved, coordination with the heritage office.
Request quotes, compare them, select the trades and prepare the contracts.
Supervise the site, secure schedule and quality, final acceptance and snagging.
What design costs – and what construction costs
For the design work, renovations run at roughly 15–22 % of the construction cost, and new builds at about 12–18 %. Work can also be billed by time, commonly 120–300 CHF per hour. SIA fee scales have not been binding since 2020, so scope and rate should be clearly set out in the contract.
Ballpark figures for an apartment renovation
These figures are guide values, not a quote. In older buildings, hidden surprises push the bill up: old pipes, damp walls, non-load-bearing floors. Plan a reserve of 10–20 %. Without that buffer, a poorly anticipated renovation quickly overshoots the first budget by 15–25 %.
In the old town we design not against the building but with it. An oriel is not an obstacle, it is the best seat in the room – if you use it well.
Old town, oriels and the abbey district: building under protection
St. Gallen wears its heritage openly: the abbey district, with its cathedral and library, has been a UNESCO World Heritage site since 1983, among the very first Swiss sites inscribed. The car-free old town is famous for its roughly 111 richly decorated oriels – from the camel to the pelican bay window. To build here is to work in a sensitive setting.
Any work on a protected or townscape-defining building falls to the heritage office – at cantonal level for the Canton of St. Gallen, and in the city through the municipal service attached to urban planning. Façades, windows, oriels and sometimes interiors may be protected. Check the status early; to our knowledge the split of responsibilities in the canton is in flux, so confirm the current position.
- Check the protection status before buying or designing, not after.
- Involve the heritage office early for façade, windows and oriel.
- Document the original fabric before anything is removed.
- Ask about possible grants toward the extra cost of heritage-appropriate solutions.
Interior designer or architect: who does what
- Focuses on space, light, materials and furnishing within the existing shell.
- Ideal for renovation, change of use and fit-out without touching the structure.
- Coordinates joiner, painter, electrician and kitchen fitter.
- Knows period details: stucco, parquet, oriels.
- Focuses on the building envelope, structure, extension and new build.
- Needed for an extension, an added storey or work on load-bearing elements.
- Responsible for the building application on larger alterations.
- Often works alongside the interior designer on complex projects.
Many St. Gallen projects need both roles. A textile villa turned into consulting rooms calls for a structural check as much as a well-resolved interior concept. Settle at the outset who leads, so that responsibilities and fees do not overlap.
Textile villas and period renovation in eastern Switzerland
The wealth of the embroidery era shaped the city: around 1900 more than half of the world's embroidery output came from the region, and the textile barons built prestige villas with oriels, frescoes and elaborate finishes. This stock is coveted today – and demanding to renovate, because original details must survive while services and comfort are brought up to current standards.
For any building erected before 1991, an asbestos check before work begins is sensible, for instance in old adhesives, panels or floor coverings. It is part of serious planning and prevents costly stop-work orders. As the hub of eastern Switzerland, St. Gallen also offers a dense network of trades specialised in such restorations.
How to find the right partner
Look for relevant references on comparable buildings, clear communication and a transparent fee model. A professional register such as VSI-ASAI and training at schools like ECAL, HEAD or within the HES-SO are markers of qualification. More important than any diploma, though, is that the person understands your building and your use of it.

In the end, preparation decides success. Clarifying protection status, budget, reserve and schedule early avoids the classic traps of period renovation. A good interior in St. Gallen respects the history of the house while making it fit for life today.

For design, renovations run at roughly 15–22 % of the construction cost and new builds at 12–18 %. By the hour, rates usually sit between 120 and 300 CHF. SIA fee scales have not been binding since 2020, so it pays to set the scope out in the contract.
Only after coordinating with the heritage office. Façades, windows and the famous oriels of the old town may be protected. Check the status before designing and involve the cantonal or municipal heritage service early.
Preserving original details – stucco, parquet, oriels – alongside contemporary services. For a building predating 1991, an asbestos check before work is important. Plan a reserve of 10–20 % for hidden surprises.
For space, light, materials and furnishing within the existing shell, an interior designer is enough. Once you touch the structure, extend or add a storey, an architect joins. Many St. Gallen renovations combine both roles.
In older buildings, plan a 10–20 % reserve, because hidden defects – old pipes, damp – only appear during the works. Without a buffer, a poorly anticipated renovation often overshoots the first budget by 15–25 %.
