Interior design and fit-out – from idea to a move-in ready apartment

The best interiors reflect the needs and lifestyle of the people who live in them. That is why it is worth entrusting your interior design and fit-out to a team that truly understands your expectations and translates them into tangible design solutions. At Fabryka Wnętrz Pod Klucz, every custom project is developed with an experienced architect and transitions seamlessly into the build phase. This ensures the concept delivers not only the desired aesthetic, but also technical feasibility within your defined budget.

Turnkey apartment fit-out with architectural design – what do you gain?

Compared to renovating without a prior concept, completing an apartment with a dedicated design ensures far greater predictability throughout the entire process. Before any work begins, you know exactly what each room will look like, which materials will be used, and what costs to expect. At Fabryka Wnętrz Pod Klucz, custom design packages are available from just 190 PLN/m². 

Documentation prepared this thoroughly allows you to make decisions based on concrete solutions. 3D visualizations let you assess colour schemes, proportions, and overall style before purchasing materials, while dimensioned floor plans provide contractors with precise guidelines. Adjusting at the design stage helps avoid costly modifications during the actual build.

Apartment finishing with an architect step by step

At Fabryka Wnętrz Pod Klucz, completing an apartment with an architect follows clearly defined stages. The cooperation begins with an initial meeting and budget planning. Based on this, you receive a tailored offer that considers your expectations and financial capabilities. Next, you sign the design agreement, which defines the scope of cooperation and subsequent project milestones.

Collaborating with the architect and budget approval

The next stage involves preparing the concept, 3D visualizations, and selecting design solutions. You have a direct impact on the outcome—the architect consults proposals with you and recommends solutions tailored to the agreed assumptions. Once the budget is approved, project delivery begins in line with the established scope and schedule. For new developer-standard apartments, determining expenses early is particularly crucial. A carefully planned budget makes cost control easier and minimizes the risk of unexpected expenses.

From concept to a finished interior

After approving the budget, you sign the fit-out agreement, and Fabryka Wnętrz Pod Klucz takes over the coordination of the entire process. A dedicated coordinator oversees the timeliness and quality of workmanship, supervising each consecutive stage of finishing work. Upon completion, you receive a meticulously finished, move-in ready apartment—complete with a welcome gift. The key advantage of having one company handle both design and fit-out is the close cooperation between the designer and the build crew. Both teams work towards the same goals, allowing the approved concept to be faithfully brought to life in your finished interior.
