In Sydney it is obvious many strata apartment blocks are dilapidated and near the end of their lives. Under-maintenance from insufficient sinking and administrative funds is often as much to blame as age.
For a building to be demolished and redeveloped, the strata scheme must first be terminated. This can happen either by application to the Supreme Court or by application to the registrar-general. The latter is the most common, as it is cheaper and easier. However, there is a catch. It is available only if all owners agree. It is impossible if one or two owners hold out, refusing to sell or agree to the termination.
