About us

Define Engineers is a practice of structural and building envelope engineers founded in 2017. At the core of the firm are the virtues of ingenuity and precision which filter through the work we do. The company is formed as a collective idea to enjoy the challenges of inventive design engineering. Vlad and Andy, the founders, have more than 20 years of combined experience in the fields of complex structural and facade engineering. They have lead and managed some of the world’s most innovative award-winning projects. At Define Engineers we believe quality engineering can deliver exceptional value to our clients and to society.

At Define Engineers we collaborate with the world’s most talented architects and designers.

Our vision

At Define Engineers we collaborate with the world’s most talented architects and designers. We are engineers who endeavour to integrate into the design process through fostering collaborations and by employing the latest technologies and research. At the heart of our organisation lies the desire for elegant and constructive solutions to any problem no matter how elaborate it may seem. This is achieved through a combination of highly analytical approach and engineering intuition. We believe the future of our industry is digital and we embrace it on all levels from our communication through to technical design and fabrication information. Our expertise in materials allows us to be innovative and push the envelope with ground breaking solutions. Our experience and understanding of the industry means our solutions are always considered in terms of value and reliability but it’s also giving us the confidence to innovate with new materials, technologies and fabrication techniques. Define Engineers’ close relationships with the leaders in the industry and outstanding research organisations means we can design, engineer, specify and test with confidence.

Define ethos

We define our work as inventive engineering, harvesting the power of computational design, advanced analysis, contemporary materials and modern manufacturing processes. At Define Engineers we believe that the best designs involve seamless integration of all disciplines involved and remain as attentive to the detail at concept level as during fabrication. We boil things down to the most fundamental truths and then question and reason up from there. We praise highly our ability to become part of tightly knit design teams where we embrace the joys and burdens of collaborative design.

  • Passion for innovation
  • Meticulous attention to detail & technical rigour
  • Computational design at the heart of our practice
