One of the first questions I hear from clients is: «how much will it cost?». The honest answer: it depends — but it can be calculated before you sign any contract. In this article I break down the price of an interior design into its components, so you know what you're really paying for and how to compare quotes in Łódź.
What determines the price of an interior design
The price of an interior design isn't a single number — it's the result of three variables: the apartment's floor area, the scope of work (whether you need just a functional layout or full contractor documentation) and the level of 3D visualizations. The more decisions you make at the design stage — instead of on the construction site — the more work the documentation requires, but the fewer surprises await you during the renovation.
How much does an interior design cost in Łódź — market ranges
To give you a reference point, here are the approximate market rates in Łódź and the surrounding area (2026). These are prices you'll find across different studios — the actual quote always depends on the scope:
Approximate market rates (Łódź, 2026)
- Concept design (functional layout, moodboard, basic visualizations): usually around 80–160 zł/m².
- Full design with technical documentation: most often around 160–320 zł/m², averaging about 270 zł/m² in Łódź.
- Design with realization support: the top of the range — the more on-site control involved, the higher.
Source: averaged market data for Łódź (2026); Łódź tends to be a few dozen złoty per m² cheaper than the national average.
Example: how much will a 50 m² apartment cost?
The easiest way to understand the range is a concrete example. For a 50 m² apartment, at market rates:
- Concept scope: 50 m² × ~80–160 zł = approx. 4,000–8,000 zł
- Full design with documentation: 50 m² × ~160–320 zł = approx. 8,000–16,000 zł
These are market ranges, not a fixed price list — which is why, instead of naming a figure «blind», I prepare an individual quote once I know the floor area and scope. The difference between a concept and a full design is above all the technical documentation — what your contractor gets in hand so they don't have to guess where the electrical or plumbing installations should go.
A good design isn't an extra cost — it's how you avoid overpaying during the renovation.
What else affects the final cost
Beyond the scope of the design, the final price can be affected by:
- The number and complexity of rooms — a kitchen and bathroom require more work than a bedroom
- The number of changes and iterations during the design
- Travel outside Łódź — a site visit in another city
- The scope of realization support and the number of on-site visits
How to choose the right scope for your budget
A concept design alone makes sense if you already have a trusted contractor and mainly need a functional layout and visualizations to «see» the result. A full design with documentation is the choice for most people buying a new-build apartment — the documentation protects you against contractor errors. A design with realization support I recommend if you're renovating remotely, investing in rentals at a larger scale, or want control over every stage without being on site yourself.

Frequently asked questions
How much does an interior design cost in Łódź in 2026?
On the Łódź market, an interior design typically costs from about 80 to 320 zł/m² — from a concept alone to a full design with documentation and realization support. The final cost depends on the floor area, the scope and the number of 3D visualizations. At Stefańska Design I prepare an individual, free quote once I know your floor area and scope.
Does the design price include 3D visualizations?
Yes — 3D visualizations are a standard part of an interior design. Their number and quality depend on the chosen scope: from a few views per room to a high-resolution series with 3D animation. The exact scope is set when quoting.
Is the design billed per m² or as a flat fee?
As standard we bill per square meter of the apartment's floor area — it's transparent and easy to estimate before the start. For non-standard projects (commercial, single rooms) we set the price individually.
Is a design worth it for a small apartment?
Yes. The smaller the floor area, the more important it is to use every centimeter. A good functional design usually pays for itself by avoiding costly mistakes and do-overs on site.
