For many investors, the question about interior design starts with the price list. That’s understandable. But before you compare rates, it’s worth knowing what you’re actually buying: just an idea for the layout, a refined functional plan, visualisations, technical documentation — or a design that’s prepared from the start for the subsequent build.
If you want a short answer: in Katowice and across Silesia interior design most often falls in the range of around PLN 80 to 250+ per m². The spread is wide because the price depends on the scope of work, level of detail, number of rooms and whether the design is meant to be just a concept or a complete base for execution.
What does a good design usually include?
Functional layout
Zone arrangement and ergonomics of daily use.
Materials and mood
Colours, surfaces, lighting and style coherence.
Documentation
Drawings and arrangements needed by contractors on site.
Decision coordination
Fewer changes during works and greater budget predictability.
What does the price of an interior design depend on?
The biggest influence on price is scope, not square meters alone. Two apartments of similar size can have completely different quotes if one needs a basic concept and the other a full design with documentation, custom built-ins and refined lighting.
- Functional layout: are you only changing furniture arrangement, or rebuilding the daily logic of the apartment.
- Level of detail: a concept alone is one thing — a full design with drawings for contractors is another.
- Number of rooms and technical zones: kitchen, bathroom, laundry or wardrobe always require more decisions than a simple living room.
- Material scope and details: the more non-standard solutions, the more design work.
- Connection with execution: a design built for a specific delivery process is usually more practical and precise.
Indicative price levels per m²
Treat the figures below as indicative. This isn’t a rigid price list, but a good reference point before the first conversation and quote.
| Design scope | Indicative price | For whom |
|---|---|---|
| Concept and functional layout | approx. PLN 80–120/m² | for investors who want to set functions well and lead some decisions on their own |
| Concept design with visualisations | approx. PLN 120–180/m² | for those who want to see style, materials and the interior mood before delivery |
| Comprehensive design with documentation | approx. PLN 180–250+/m² | for investors who want to organise the whole project and limit the risk of changes during works |
In practice, a well-prepared design costs less than a series of fixes done after the crew arrives. That’s why interior design should be assessed not as an additional cost, but as a tool that organises the budget and process.
What does an interior design usually cover?
It depends on scope, but with a well-prepared design the client gets not just inspiration, but above all a set of decisions needed for smooth execution.
- analysis of the household’s needs and lifestyle,
- functional layout of rooms,
- selection of materials, colours and lighting,
- visualisations showing the aesthetic direction,
- technical drawings for contractors,
- list of key materials and equipment.
The more detailed the design, the fewer decisions you have to make under time pressure once crews are on site.
How long does interior design take?
Design lead time depends on the scale of investment and how quickly the investor makes decisions. For a developer apartment it usually looks like this:
- 1–2 weeks to gather needs, take measurements, brief and plan the functional layout,
- 2–3 weeks to develop the concept and refine the direction,
- 1–3 weeks for materials, visualisations and technical documentation.
For a standard investment that’s usually about 4–8 weeks. For larger houses, more demanding interiors or longer decision processes, the design takes longer.
When does interior design genuinely save money?
The biggest saving doesn’t come from the drawing itself — it comes from limiting the number of changes during execution. This is especially important in new developer apartments, where investors often start with “we’ll see on site” and end up moving sockets, changing plumbing and buying things in a rush.
A well-prepared design helps to:
- plan the budget better before work starts,
- avoid clashes between installations, furniture and lighting,
- order materials in the right sequence,
- limit fixes and unnecessary “quick” decisions.
Is it worth combining design and execution in one company?
In many cases yes — because then the design is created from the start with real execution capabilities in mind. It’s not just an aesthetics question, but also one of work sequencing, purchase logistics, sensible technical solutions and budget control.
If one team designs and executes, the risk of a gap between visualisation and reality is usually simply lower. So at the consideration stage it’s worth seeing not just the design itself, but also what completed projects look like. See Hekabe projects and the Atal example if you want to assess the standard of detail and consistency of the result.
Interior design in Katowice: what to settle before the conversation?
Before you ask for a quote, prepare a few pieces of information:
- square meters and property type,
- whether it’s a developer apartment, house or commercial unit,
- what scope you’re interested in: just a concept or a comprehensive design,
- whether you plan execution with the same team afterward,
- your indicative budget and start date.
That way the design conversation quickly moves from inspiration to real decisions and a real quote.
Frequently asked questions
How much does an apartment design cost per m²?
Indicative ranges most often fall between approx. PLN 80 and 250+ per m², depending on scope and level of detail.
Can I order a design for one room?
Yes. Many projects start with the kitchen, bathroom or living zone, where most technical and budget decisions are made.
How long does interior design take?
For a standard developer apartment, usually around 4–8 weeks, depending on scope and decision pace.
Is it worth commissioning design and execution from one company?
In many cases yes, because it reduces the risk of misunderstandings, fixes and gaps between design and final execution.
