The Story of Core Construct

Core Construct was founded with a simple goal: to bring honesty, professionalism, and real craftsmanship back to the renovation and construction industry in Israel.

We've grown from a small operation into a full-service company trusted by dozens of homeowners across Jerusalem and the Central District.

Jonny Goldsmith

Hi, I’m Jonny. I moved to Israel from New York in 2012, bringing with me four generations of roofing and construction heritage. While I’m a builder by trade, I’m a partner to my clients by choice.

In 2020, I founded Core Construct to bring a more personal, client-focused approach to the industry. I pride myself on being easy-going and accessible — I want my clients to feel like they have a direct line to someone who truly cares about their home. Whether we are roofing or remodeling, my goal is to deliver "American-standard" quality with a level of transparency and availability that makes the entire process feel simple.
