San Diego County · Founder-Led Construction

Powerful builds engineered for coastal living.

From ground-up residences to accessory dwelling units, Troia Construction pairs executive oversight with field-first leadership. Based in La Jolla, we deliver precise craftsmanship, rapid decision making, and clear communication at every milestone.

Southern California Builders

Angelos started in Limassol, Cyprus, where at his family company he built over 50 timber-frame homes, becoming the first to bring this construction style to the island. He moved to the United States to build on his own path, where he met Robert Amarin, an experienced contractor in the mining industry. They began with smaller projects, grew each time, and founded TROIA Construction.

From our home base on Prospect Street in La Jolla, we guide homeowners, developers, and architects across Greater San Diego with tailored project delivery. Robert and Angelos stay on site, on the phone, and accountable from the first consultation through turnover.

Builder-led value, zero middleman markups

Every project is run by the founders themselves, combining cost transparency with field-first craftsmanship from day one.

No Middleman Markup

“As an owner-operated builder with an in-house team, we eliminate the heavy markup that ‘paper contractors’ add to your final price.”

Built By Real Builders

“Our founder’s deep, hands-on experience in framing and concrete means we’re true craftsmen, not just project managers.”
