Who we are

We are with you every step of the way, from vision to reality.

We support you at every stage — from the first outline of an idea to a unique design solution, from construction through to commissioning.


Tetiana Cherkai

Director @ TCH Project

There are many design companies in Ukraine. So why choose us?

Our answer is simple: we do not just design buildings — we create intelligent facilities.

Our approach is built on three core principles:
  • Efficiency and resource conservation: we implement solutions that optimise the use of energy and resources.
  • Systematic approach: we use standardised products and proven system-based solutions that enhance functionality and comfort without unnecessary cost.
  • Safety without compromise: we place special emphasis on fire protection systems, structural strength, and reliability in the challenging realities of wartime.

We work with public and industrial facilities of any complexity. Our unique experience allows us to design not only in accordance with Ukrainian building regulations, but also to international standards (EN, NFPA), which is essential for attracting foreign investment.
