You cannot “strata a strata” – you can only re-subdivide a strata scheme and you will require a notice of resolution from the strata company (unit owners) permission of the entire Strata scheme. Under Survey Strata you cannot have multi-tier strata lots, only single tier (side by side). It is possible to get around this by reverting the strata scheme back to freehold (application to WAPC) and cancelling the survey strata but this is a long process. If the units are built it may be best to rent them and will be the only option if you cannot obtain approval from the strata company. Further-more you cannot have buildings/stores/car-bays encroach parent land boundaries or have a part lot over an easement.
