How much does interior finishing cost in 2026?

How much does turnkey interior finishing cost in 2026? At estimental, we answer this question based on actual cost estimates prepared for our clients — not on general market approximations.

The cost of comprehensive turnkey finishing at our studio in 2026 ranges from 4,560 PLN/m² to 9,500 PLN/m², depending on the finishing standard, scope of work and chosen materials.

The prices we quote include not only basic finishing, but also custom joinery, air conditioning and freestanding furniture. The average project cost at our studio is currently around 5,200 PLN/m².

Every project is different, because every client has different needs, expectations and scope of work. Two units of identical size can differ in budget by hundreds of thousands of zloty.

General construction works and custom joinery usually have the greatest impact on the budget. The greater the functional remodelling and the higher the standard of materials, the higher the final cost.

The only reliable way to determine costs is a detailed cost estimate prepared for a specific property and a specific scope of work. At estimental, we prepare it free of charge after a meeting with an architect — with no obligation and no rounding.
