COS DEVELOPMENTS

Residential land development
across South East Queensland.

Identifying well-located land and creating considered residential communities through disciplined planning, development and delivery.

INTRODUCTION

Local knowledge. Disciplined development.

COS Developments is a privately owned South East Queensland property development company focused on residential land subdivision in established and emerging growth areas.

We manage the development process from site identification and acquisition through due diligence, planning approvals, civil delivery, marketing and settlement.

LANDOWNERS

Own land with development potential?

Selling property for development is different from selling a conventional residential property.

COS Developments work directly with landowners to understand their property, investigate its development potential and determine whether there is an opportunity that works for both parties.

If we have contacted you about your property, or you believe your land may have development potential, we would be happy to have an initial confidential conversation.
