Comprehensive interior finishing Warsaw

estimental is a Warsaw-based interior design and build studio run by licensed architects who are members of the Chamber of Architects of the Republic of Poland. We combine interior design with complete turnkey execution, providing both within a single service and under one contract. We operate throughout Warsaw and the entire Mazowieckie region, working on both newly built developer-standard apartments and renovation projects.

Every project is priced individually, without rigid finishing packages, and our clients receive a detailed cost estimate before signing a contract.

We work according to our own quality standards, which are significantly more stringent than the applicable European standards. As these standards are explicitly included in our contracts, clients have a clear and straightforward way to verify the quality of our workmanship.

In 2026, the cost of comprehensive turnkey interior finishing at our studio ranges from PLN 4,560/m² to PLN 9,500/m², depending on the finishing standard, scope of work and materials selected. The prices we provide include not only the basic finishing works, but also custom-made furniture and built-ins, air conditioning and freestanding furniture. Following a consultation with an architect, every client receives a precise, detailed cost estimate — without rounded figures or broad estimates — free of charge and before signing a contract.

Our service is designed for clients aged 25–65 who are looking for excellent workmanship, professional expertise and convenience, and who want to entrust the entire interior finishing process to one reputable company. Our clients do not have to spend time travelling between showrooms or searching for finishing materials themselves. We have an extensive in-house library of samples and catalogues from leading manufacturers of flooring, paints, wallpapers, furniture fronts, worktops and sanitary fittings. If there is something we do not have in our collection, we arrange for the relevant samples to be delivered for our design meetings, saving our clients a considerable amount of time.
