Who you're hiring
Troia is owner-operated. Robert Amarin is on every job. No layers of project managers, no subcontracted oversight, no middleman markup.
From the first site walk to final inspection, you deal directly with the licensed builder responsible for your project. That means faster decisions, tighter cost control, and craftsmanship we put our name behind.
"We don't manage builds from a desk. We frame it, pour it, and stand behind every wall we raise."Talk to the builder
What we build
Three ways we put the license to work.
02
Custom Homes & Remodels
Ground-up residences and whole-home renovations, from preconstruction budgeting through final punch lists, with schedules that hold and design intent preserved.
03
Structural Framing
Framing is the one trade we self-perform, and the only standalone scope we take on. As a licensed General B contractor, our own crews raise the structure your entire build depends on, square and plumb to engineered plans.

Preconstruction
Every build begins at the table.
Before a single board is cut, we sit down over the plans, aligning scope, budget, and schedule so the build runs clean from day one. It's how we protect your timeline and your investment.
