  • Inclusivity and transparency

Thornhill Estate is an upmarket residential estate and we take pride in our serene surroundings, the tranquil setting, secure open spaces and natural beauty of the many trees and waterscapes that lend it a unique country feel.

We are very fortunate to have a well-established management team of staff and Trustees, assisted by various sub-committees, with various portfolios including security, maintenance, gardens, architecture, governance, financial, legal and social.

To maintain our current privileged lifestyle and security requires that all residents and their guests adhere to the rules and regulations prescribed in the governance documents. It is incumbent on all residents of Thornhill Estate to familiarise themselves with the THOA Constitution and the Code of Conduct, Rules and Regulations, including any other documentation that may become relevant from time to time. Everything you need to know about living on the Estate is available below, including the Constitution and Conduct Rules, together with the various Addenda and forms.

If you are still unsure about something, take a look at the FAQs and if your questions still remain unanswered you are welcome to contact the office.

The safety and security of our residents is of the utmost importance to the Thornhill Home Owners Association. In this regard we require the co-operation and compliance of all residents and their visitors in respect of our Security Rules and Regulations.

iMvula Protection Services is our contracted Security Service Provider and has a proven track record on our Estate. Besides the two Armed Reaction vehicles patrolling exclusively within our Estate, we also have iMvula Security staff positioned at our Main Gate Entrance and on-foot patrols along our perimeter and inside the Estate.

It is important to note that, whilst iMvula take care of our common areas and perimeter, it is also the responsibility of our homeowners to ensure that basic security measures are taken to protect their homes.

Access control is governed by means of a biometric (fingerprint) system on which all residents are required to be registered. Should an individual’s fingerprints not be able to be read by the system (as is sometimes the case with elderly people), then that person will be issued with a free Access Card, with a replacement cost of R150.00, should the card be lost or damaged.

Please ensure that you familiarise yourself with the security procedures below. Should you have any questions please contact the Estate Management.

Security Overview


The Security objectives provide an environment that minimises potential criminal activity by way of:

  • Gated controlled access
  • Perimeter fencing and
  • Security patrols of the common and perimeter fence.

They maintain good conduct standards of members and occupiers of erven in the Estate for the general benefit of all members in accordance with the Code of Conduct, Rules and Regulations adopted by the Thornhill Home Owners Association;

In order for any Security procedure to work, it is essential that all residents and visitors participate in this process, as no system could operate without the correct mindset of the participants. In order to achieve this each resident within the Estate has certain responsibilities and these are as follows:

  • To ensure the security and integrity of his or her own household. It is impossible for any security force to be able to secure every house in the Estate the size of Thornhill;
  •  To abide by the access control system rules; regardless of how inconvenient you may believe the system is, it is there for your protection;
  • To assist the general security by reporting suspicious activities timeously so that they may be reacted to immediately.


The Security functions of the Estate are directly controlled through the Estate Management team that operates on mandates given by the Security Committee. This Committee is chaired by the Trustee holding the Security portfolio and comprises elected residents, Estate Management and representatives of the Contract Security Company. The Committee meet on a monthly basis to:

  • Constantly assess the Security risks;
  • Assess methods of preventing and minimising the risks;
  • Assess the performance of contractual services;
  • Adjudicate tenders and equipment purchases;
  • Review the presentation of all incidents that have occurred since the previous meeting. Where serious incidents occur, the Chairman and Committee members are advised immediately such reports are received.


Security personnel are contracted by the THOA through a Security contractor who is appointed by the Security Committee and Trustees through a tender process.

The following security functions are carried out by our contractor:

  • The provision of Estate Security Supervisors on a 24/7 basis. The supervisors are responsible for ensuring that all security functions are properly fulfilled; they attend to any reports received, including the non-compliance of any conduct rule;
  • The supply of manpower at the gates on a 24/7 basis. These guards provide oversight of the automated access control system for residents and visitors. The personnel are under direct instruction from THOA not to act on their own initiative in allowing entry or egress; where it is necessary for them to over-ride the system for any reason, they may only do so under direct instruction from Thornhill Management.
  • The supply of patrol guards and patrol vehicles based on the given mandate;
  • THOA does not provide a remote monitoring and reaction function. However, such service may be obtained from the Security contractor as a privately contracted function independent of the THOA. Estate Security and the armed patrol vehicles are nevertheless under instruction to assist residents wherever possible.

Personnel performance is appraised on a monthly basis and in terms of our agreement: where performance levels drop below a pre-agreed level the service provider is placed on terms and may be required to decrease their monthly billing by 1% for each percentage point below the pre-agreed level.


All telephonic reports should be made through the Estate Management telephone numbers:

  • THOA Estate Office 011 608 0835
  • Main Gate 011 608 4361

The Main Gate telephone is manned on a 24/7 basis, but the Estate Office telephone is only manned during office hours.

Should you note any transgressions by the Security Personnel please do not take up the matter with them. Instead please report this to the Estate Management who will take the necessary action where required.

All contractors are required to register with the office; failure to do so will result in a Non-compliance Notice being issued to the homeowner. Please click on links below to view the contractors rules and registration forms.
