Frequently asked questions — interior design

An interior design covers 7 service stages: a project meeting with a site survey, material selection and moodboard, a 2D functional layout, 3D visualizations (and AI animation in the Premium package), technical documentation with a cost estimate, realization coordination and final styling. The whole project is delivered as one package — we define the scope at a free project quote.

The technical documentation for an interior design is a full set of construction drawings for the renovation crew: wall elevations with dimensions and material notes, an electrical diagram (sockets, light points, switches), a plumbing diagram (water and sewage points) and a full material specification with prices. Plus an execution cost estimate, so you know what everything will cost before work begins. Technical documentation is available in the Standard and Premium packages.

A 2D floor plan (functional layout) is a top-down plan with furniture, built-ins and dimensions — essential for the renovation crew. A 3D visualization is a photorealistic render showing what the interior will look like after the renovation: specific materials, furniture, colors and lighting. Visualizations let you make material decisions before the renovation and avoid costly changes mid-way. In the Basic package: 3–4 views, Standard: 5–7 views (higher quality), Premium: 8 high-resolution views + AI animation. More on the 2D plan: floor plan design.

An AI animation is a short video (usually 15–30 seconds) showing the designed interior in motion — as if you were walking through the space. It's generated from the 3D visualizations using AI tools. Available exclusively in the Premium package. It's great for showing the design to family or the renovation crew.

I design both single rooms (bathroom, kitchen, living room, bedroom) and whole apartments and houses. A single-room design is a good option for a staged renovation or when you want to test the collaboration. A whole-home design gives aesthetic coherence and is more cost-effective per m².

Yes — material selection is an integral part of every package. In the Basic package I prepare a moodboard with a list of recommended materials and price alternatives. In the Standard package I deliver a full specification with products, prices and links. In the Premium package I additionally arrange showroom visits with the client (up to 4 hours), so you can see and touch the materials before deciding.

Realization coordination means meeting the renovation crew on site — I walk them through the design, answer the contractors' technical questions and verify they understand every detail. It prevents errors caused by the crew's own interpretation of the design. Realization coordination isn't mandatory, but I strongly recommend it for full renovations. It's available in the Premium package. If you'd like the designer by your side for the whole renovation, you can add design supervision (nadzór autorski) as a separate service.

The cost depends on floor area, the number of rooms and the scope: a concept with 3D visualizations (Basic package), full technical documentation for the crew (Standard), or realization coordination as well (Premium). I prepare an individual quote after a free 30-minute project call — no obligation. The same terms apply in Łódź and across the Łódź region (Pabianice, Zgierz, Piotrków Trybunalski, Bełchatów, Skierniewice and nearby).

The Basic package includes: an online project meeting, site survey, functional layout (2 versions), moodboard, material selection and 3D visualizations (3–4 views). No technical documentation — suitable when you have a trusted crew that doesn't need construction drawings.

The Standard includes everything in Basic, plus: an on-site project meeting (up to 4 h), functional layout (3 versions), higher-quality 3D visualizations (5–7 views per room), a full material specification, technical documentation (electrical and plumbing diagrams) and an execution cost estimate.

The Premium includes everything in Standard, plus: 8 high-resolution 3D views, AI animation, material showroom visits (up to 4 h), realization coordination, final styling of the finished space and a personalized artwork for your interior painted by the designer.

Payment is split into three parts, and you always pay for a stage you've already seen and approved — no upfront payment for the whole project:

1. 50% — after the measurement and the approved concept (functional layout),
2. 30% — after you approve the 3D visualizations,
3. 20% — on delivery of the complete design (in the Standard and Premium packages — with technical documentation).

Design supervision is my support during the renovation: site visits, answering the crew's questions, checking the work against the design and helping with orders. It isn't included in the design price — it's a separate service billed per site visit, and you decide whether you need it. To make the renovation easier to plan, I offer visit packages matched to the floor area:

• apartment of about 40 m² — 3 visits,
• apartment of about 80 m² — about 5 visits,
• apartment of about 100 m² — up to 8 visits.

We set the exact number of visits based on the scope and schedule of the renovation. The Premium package includes realization coordination.

The first meeting (30 minutes) is free and non-binding — over Google Meet or by phone. It lets you assess our working style, and lets me understand the project scope and propose the right package.

I always communicate all costs at the start — no hidden fees. Additional costs can only apply to: revisions beyond the package scope (e.g. changing the entire layout after approval), extra site visits outside the Premium package, or special orders. Every such option is discussed and priced in advance.

Interior design at Stefańska Design covers 7 stages. We start with a project meeting and questionnaire, then a measurement visit with a site survey. Next I prepare the material selection and moodboard, several 2D functional layout variants and 3D visualizations. Once the design is approved, I compile the technical documentation with a cost estimate. The Premium package adds realization coordination on site and final styling. At every stage you know what's happening and what to expect next.

The timeline depends on the chosen package and floor area. Basic and Standard packages: ~3–4 weeks for an apartment up to 60 m². The Premium package with realization coordination: ~7–10 weeks plus the renovation time. If decisions are made quickly and revisions are limited, it can be shorter. The clock starts when the contract is signed and the materials (floor plans, photos) are handed over.

As early as possible — a designer can only genuinely help before the key renovation decisions are made. When buying a new-build apartment: 3–6 months before the planned fit-out (developer customization requires a design). For a full renovation: 6–8 months ahead, to allow time for design, orders and material deliveries. If you're not sure — write to me and we'll figure it out together.

Meetings take place at your home, online (Google Meet/phone) or out and about (material showroom visits). The first meeting — always free, usually online. On-site surveys: I cover Łódź and the entire Łódź region — Pabianice, Zgierz, Piotrków Trybunalski, Bełchatów, Skierniewice, Sieradz and nearby. Design presentations and revisions — online or in person. Clients outside the region are served fully remotely.

Yes — the design is created iteratively, in close cooperation with you. At the concept stage you get revision rounds within your chosen package. If bigger changes come up after the technical documentation is approved (e.g. changing the entire functional layout), they may be priced separately. I make sure every stage stays clear and flexible for you.

Your involvement matters, but you don't have to be present at every stage. Active participation is needed for: the brief and design questionnaire, approving the functional layout variant and signing off the visualizations. The rest — design work, specifications, documentation — I handle myself and present as finished proposals.

Three things are enough for the first meeting: (1) a floor plan — the developer's PDF, a plan from Google Maps or your own measurements; (2) a few inspirations — photos from Pinterest, Instagram or interior magazines; (3) a rough renovation budget. If you don't have any of these — reach out anyway. We'll start with a conversation about your needs.

No — it's best to choose the crew after the technical documentation is ready. With a finished design and cost estimate, you can invite several crews to quote and compare offers on the same basis. It's standard practice that usually lets you negotiate better prices and avoid budget surprises.

Yes — developer's standard (a finished shell with plaster and screed, without finishes) is the most common situation among clients in Łódź and the region. It's the perfect moment for an interior design: you have full freedom in planning installations, you can design the lighting from scratch and choose all the materials without constraints from previous decisions. I work with new builds across the entire Łódź region.

I design interiors tailored to your preferences and lifestyle — I don't impose a single aesthetic direction. The most common styles: modern minimalism, Scandinavian, loft/industrial, classic and eclectic. If you have something else in mind — boho, japandi, glamour, vintage — we'll find the right direction together at the first call.
