"ISP Digital Design" LTD

For us architecture is not just a profession, but a vocation. Our professionalism, diligence, timely delivery, and responsibility to the task are only some of the reasons to select us as a partner in realizing the architectural idea.

Our understanding of contemporary architecture is influenced by the development of modern technologies and the introduction of digital design in everyday design work. Our work draws inspiration from "hi-tech" architecture of the West and the Far East, adapted to the architectural traditions of Bulgaria. In each of our buildings we strive to combine a memorable architectural appearance with clear functionality and aesthetics.
ISP Digital Design LTD carries out all activities related to the preparation of project documentation for investment projects, including: architecture, constructions, electrical, plumbing, heating and ventilation, geodesy, geology, health and safety, landscape projects, and technology projects. A full list of our services can be found on our services page.
