Sample selection is the moment when plans turn into real surfaces, materials and appliances: floors, tiling, kitchen, sanitary installations and countless details. Contrary to what is often assumed, the big cost lever in a project is not the material, but the volume, the floor area and the plot.
That is why saving on the fit-out rarely pays off: the material is what you see and use every day. What matters is not choosing as cheaply as possible, but choosing consciously. Every option needs a price tag, so that material selection in a Swiss house build is never a decision made in the dark and you know every extra cost.

Do your material wishes fit your budget?
A short review brings clarity before extra costs add up.

1. What is sample selection?
Sample selection is the phase in which clients choose the specific materials, surfaces and fittings for their building. Abstract plans turn into tangible decisions: which floor covering, which tiling in the bathroom, which kitchen, which taps, which doors.
For many clients this is the most emotional phase of the project, because the house takes on a character for the first time. That very emotion is also the risk, because it pushes the budget out of view.
2. When does sample selection take place?
Sample selection usually takes place after the building application and before or during construction. The exact timing depends on the trade: some things have to be decided early, others later, such as surfaces and appliances.
What matters is that the sample selection is coordinated with the construction programme. Anyone who decides too late blocks the site. Anyone who decides too early and unprepared pays for corrections later. Sound detailed design sets out when which decisions are needed.
3. What impact does material selection in a Swiss house build have on costs?
An honest assessment helps here: the largest part of the construction cost is not fixed during sample selection, but much earlier. Volume, floor area, number of storeys, basement and plot determine the cost framework far more strongly than the choice of a floor covering. The article What does it cost to build a house shows how these big levers work.
One important conclusion follows from this: saving on the material achieves relatively little, but it can be a daily irritation, because surfaces and fittings are what you see and touch every day. It makes more sense to invest consciously in quality there and to settle the big cost questions early, in the concept phase.
Sample selection still needs discipline. Extra costs add up, and without an overview you decide item by item in the dark. The value of material selection in a Swiss house build therefore lies less in saving than in deciding consciously.
4. What does "standard" mean in the specification?
The specification defines which fit-out standard is included in the agreed price. It is the reference against which every choice during sample selection is measured. Anything above that standard is an extra cost. Anything below it should produce a credit.
That is exactly why the specification matters so much. If it is vaguely worded, such as "high-quality materials" or "to be chosen", the clear reference is missing and almost every choice becomes an extra cost. How to review a specification is covered in the article Having the construction contract and specification reviewed.
5. What are budget items and extra costs?
In practice, contractors often work with budget items: an amount is set aside for the kitchen, the tiling or the sanitary installations, within which the client can choose. If the choice lies above that amount, an extra cost arises.
Area | Standard (budget item) | Possible extra cost |
Kitchen | e.g. CHF 25,000 | + CHF 10,000 to 40,000 |
Bathroom (per bathroom) | Standard fit-out | + CHF 5,000 to 20,000 |
Floor coverings | Laminate / simple parquet | + CHF 30 to 120 / m² |
Sanitary taps and fittings | Standard range | + CHF 200 to 1,500 per item |
Indicative values, strongly dependent on product and project. Have every extra cost itemised before you decide.
Standard item: clearly defined scope, included in the price.
Budget item: an amount as a placeholder, with the specific choice made during sample selection.
Extra cost: the difference when the choice lies above the standard or the budget.
Basic rule: every option needs a price tag. Have the extra cost shown to you for every choice before you decide. That way you decide consciously about quality instead of exceeding your budget without noticing.
6. Which areas are sampled?
Almost everything that is visible or tangible is sampled. The most cost-relevant areas are usually the kitchen, the bathrooms and the floors.
Floor coverings (parquet, tiling, natural stone)
Wall and floor tiling in wet rooms
Kitchen including appliances and worktop
Sanitary appliances and taps
Internal doors, fittings, balustrades
Heating, ventilation and controls (in part)
Experience shows that the largest extra costs arise in the kitchen and in the bathrooms, because many high-quality options are available there.
7. Which mistakes happen most often?
The typical mistakes are less a question of taste than of preparation.
Deciding without a budget comparison: extra costs are accepted one by one, without seeing the total.
A vague specification: the reference against which extra costs are measured is missing.
Emotional upgrading: "while we are building anyway" leads to a higher standard item by item.
Late changes: decisions are changed after ordering, which triggers additional costs.
These mistakes are avoidable if you treat sample selection as a conscious decision and not only as a matter of taste.
8. How do you prepare as a client?
Good preparation halves the risk. Before the sample selection appointment, get clarity on the agreed standard and on your budget for surcharges. Define in advance where you want to invest and where the standard is enough.
Read the specification and mark the budget items.
Set a conscious surcharge budget that you do not want to exceed.
Prioritise: where does quality pay off and where does it not (visible versus invisible)?
Ask for the extra cost to be itemised transparently for every choice.
That way you make your decisions consciously and not in the moment.
9. How do you keep track of the budget and the overall picture?
During the sample selection, keep a simple list of the chosen items with their respective extra costs. That way you see continuously how the total is developing, instead of only at the final account. This reconciliation is part of general cost control during the construction phase.
It helps to look at extra costs not in isolation, but against the overall budget. A single surcharge looks small, the sum of many surcharges rarely is.
10. Three practical examples
Practical example 1: the sum of the small surcharges
One family chose "just something a bit better" for many items. Individually the extra costs looked small, together they clearly exceeded the budget. A running list would have shown the trend early.
Practical example 2: the vague specification
In one project the specification was imprecisely worded. Almost every choice therefore became an extra cost, because no clear standard was defined. A review before signing the contract would have prevented this.
Practical example 3: consciously invested, consciously saved
One client decided in advance to invest in the kitchen and the main bathroom and to stay with the standard for the secondary rooms. This clear prioritisation held the budget and led to a coherent result.
11. Common questions about sample selection
What is sample selection in a house build?
Sample selection is the phase in which you choose the specific materials, surfaces and fittings, such as floors, tiling, kitchen and sanitary installations. This is where the fit-out standard is set.
Should you save on the material?
Usually not. The big cost lever lies in volume, floor area and the plot, not in the material. You see and use the material every day, so conscious quality pays off more there than saving.
How do I avoid extra costs during sample selection?
By having the extra cost shown to you for every option and comparing it against the standard defined in the specification. A running list of the surcharges keeps the budget in view.
What is a budget item in the specification?
A budget item is a placeholder amount, for example for the kitchen or the tiling, within which you can choose. If your choice lies above it, an extra cost arises.
Where do the largest extra costs arise?
Mostly in the kitchen and in the bathrooms, because many high-quality options are available there. This is where conscious prioritisation pays off most.
12. When independent support is worthwhile
Material selection in a Swiss house build calls for decisions whose cost consequences a layperson can hardly judge. Independent support compares the specification with your wishes, sets out extra costs transparently and protects you from exceeding the budget unknowingly.
raumwert plus supports clients with this as part of its owner's advisory, so that sample selection becomes a conscious decision and not the most expensive surprise of the project.
