Not every site should move forward. Our role is to help you understand what is worth pursuing, what needs caution, and where the real value may sit.
What this initial read can't tell you
We're builders. That's why we charge for our judgment first — a builder who can't tell you "don't build" is giving you a sales pitch, not advice.
About the practice
GY & Co. is a boutique practice focused on land strategy for 600–900sqm homeowners in the North Shore and Eastern Suburbs. We exist to answer one question honestly — before you commit to a builder, what does your block actually support?
We don't build. We don't design. We don't take referral fees from builders. Our only job is to help you decide clearly — which is why every site review here uses public NSW planning data, and every deeper feasibility is site-specific, not templated.
Site Review is founder-led. When you apply for a Feasibility Review, you're speaking to the advisor doing the work — not a call centre, not an intake form pretending to be personal. We take a limited number of properties each month.
Next step
This page gives you a directional read on the site. To act on it, you need site-specific numbers — exact CDC eligibility, real cost ranges, and an honest call on viability. Pick the path that fits where you are.
