Our approach is personal, flexible and cost-effective.

We recognise that every situation is unique. Our team has grown to meet the holistic needs of our clients, providing them with impeccable credentials in every aspect of property, from initial feasibility and options, to the structuring of joint ventures through to project management. We firmly believe one solution does not fit all.

The first thing we do is listen. We meet you face-to-face. We want to hear about your objectives, your issues and your priorities.

What we’re aiming for is a level of connection and understanding that will help us become part of your team, matching objectives to outcomes. Certainty of outcomes, value maximisation, bankability and delivery that meet the risk profile of your organisation are at the core of the SEMZ approach.



At SEMZ, we set ourselves high ethical standards. We believe property is a resource that should be utilised in a sustainable way that best meets our clients’ objectives.

This means we’re making a positive contribution towards an improved legacy for future custodians and generations.

As part of this legacy, a percentage of all our earnings is redirected to support research into housing affordability models.

We enjoy working hard and doing what it takes to deliver outcomes. What is most important to us is to foster authentic, trusting, loyal, beneficial and positive relationships beyond the specific tasks at hand.
