StructArt

What StructArt does

StructArt is a Bulgarian civil engineering and construction company headquartered in Sofia, founded in 1998 and operating for over 25 years (originally as HELI-N OOD, rebranded to StructArt in 2019). The company specializes in residential construction — designing, developing, and selling its own apartment buildings — and provides general contracting services across public, administrative, industrial, residential, and hotel projects, having completed over 30 sites and 200,000+ square meters of gross floor area in Bulgaria.

StructArt's technical backbone is its 5D Building Information Modeling platform, which integrates design, schedule, and budget into a unified project delivery system, supplemented by specialized expertise in geosynthetic soil reinforcement, crystalline concrete waterproofing, and green roof construction. The company owns an equipment fleet including Liebherr tower cranes, scaffolding systems, and excavators, which is operated both for internal projects and rented externally via subsidiary RentConsult Ltd. Additional revenue lines include natural stone import (marble, travertine) and property management of company-owned real estate.

The business model combines own-development sales (one-time, project-based apartment sales), general contracting (professional services, quote-based), equipment rental, and materials supply. Go-to-market is direct sales via office visits, phone lines, and email, targeting four primary segments: residential property buyers/investors (primary), commercial/institutional clients, construction companies/contractors, and government/municipal projects. The company operates across multiple Bulgarian regional markets (Sofia, Bansko, Kardzhali, Sozopol) and is led by its two co-founders, Engineers Nikolay Kolev and Nikolay Yanev.
