## Positioning

GY & Co is not positioned as a generic builder. Its core point of difference is land-first feasibility before design and construction.

The company helps homeowners answer:

- Can my block support a second-storey addition?
- Should I extend out, add up, add a granny flat, test duplex potential, or avoid overcapitalising?
- Is CDC realistic, or will the project need DA?
- What site constraints should be checked before paying for drawings?
- Does the extension make sense for the family, council pathway and likely build budget?
