About UCG Poland
American project discipline, built in Poland.
UCG Poland is part of United Construction Group, founded by U.S. Marine Corps veteran Brandon Jarnesky.
Our story
From United Construction Group to Poland.
United Construction Group was founded by Brandon Jarnesky, a U.S. Marine Corps veteran, on one idea: a client should hire a single team and never need another contractor.
Brandon brought the discipline of military service to the job site: briefed crews, clean sites and documented days. Over more than a decade, that standard has carried United Construction Group from single bathrooms to whole homes, custom builds and commercial fit-outs for national brands. We do not just build structures; we plan, design and build the spaces people want to live in.
UCG Poland brings the same model to Poland, focused on commercial development (offices, hotels, retail and mixed-use buildings) and a select number of private residences: one accountable team for design, permits and construction.

Values
- 01
Craftsmanship
Veteran discipline on every site: briefed crews, clean work areas and documented days, so the finish is as precise as the schedule.
- 02
Transparency
We tell you honestly whether we are the right team for your project. If we are, you get a real number and a real schedule, in writing.
- 03
One-team accountability
From the first visit to handover you speak with the person accountable for the work, not an account manager relaying messages.
- 04
Attention to detail
Shadow gaps, stone edges, the feel of a switch, and a site-safety programme that protects your family and neighbours. We care about what others overlook.
