we believe in creating communities for everyone to participate in!

our purpose

In 2014, we commenced work on our first foray into socially responsible housing with the construction of 10 specialist disability units at the Belle Apartments, Belmont. The development was undertaken for the Summer Foundation as part of study for the yet to be formed National Disability Insurance Scheme. The housing project was a huge success and since then we have continued down the road to provide much needed assisted living solutions away from the segregated and institutional housing models of the past.

At insitu Housing, we believe we not only have the responsibility, but also the opportunity, to enable people with disabilities to participate equally in our communities. We are committed to developing beautiful and innovative apartments and communities that are structured to support residents in developing their capability to live as independently as possible.

our core values

Our Model

Along with the beautiful and functional features that are presented within our SDA apartments, we have incorporated the concierge model to better service our residents along the East Coast of Australia.

The concierge model includes an on-call support worker available for anything you may need. With our concierge presence, YOU have the option of reducing your one-on-one support and living the life that you choose.

A few examples of how the concierge can assist YOU:

  • The extra person to assist with a hoist transfer
  • On-call overnight supports, or unexpected supports that occur
  • Emergency support, for when something goes wrong

The concierge model of living allows YOU more choice and control over who provides your day-to-day assistance and personal support.

Ultimately, we are here to provide you with more freedom to live how you like. We encourage you to bring your personal supports and day to day supports with you work with you.

U choose who comes and goes each day and provides your supports.
