From a single engineering firm to a multi-brand group
Mechart has grown the trust it earned in mechanical engineering into digital products and web production, becoming a multi-brand technology and engineering group.
Our Story
For over 15 years, Mechart has provided professional design, consultancy and advisory services in mechanical engineering. We have successfully delivered more than 500 projects across residential, commercial and industrial buildings.
On top of this engineering heritage, we added new capabilities to meet the needs of a changing world. We brought our growing portfolio of solutions under a single corporate umbrella, forming the Mechart Group of companies.
Today, our umbrella covers Mechart Engineering in mechanical engineering, Mechart Digital in digital production, and SiteDesk in PropTech. Each specializes in its own field while sharing a common understanding of quality, reliability and innovation.

Our Mission
Our mission is to integrate our deep engineering discipline with the digital capabilities of our era, delivering reliable, sustainable and high-value solutions to our clients. From the first feasibility study to commissioning, we anchor every step in technical excellence, transparent process management and measurable quality. Our aim is not only to meet the needs of today, but to build future-ready structures and systems that create long-term value for our stakeholders.
Our Vision
Our vision is to be a pioneering technology and engineering group—recognized as a benchmark in its region and trusted internationally—with a broad capability spanning engineering, digital production and PropTech. By combining the strength of our multi-brand structure with a continuously evolving R&D mindset, we aim to set the standards that shape our industries, create a lasting difference in every field we enter, and make sustainable growth a corporate habit.
