…The plan has been registered in June 2011, but seems to be unusual in that the “whole of the building including floors, walls, ceilings, roof, verandahs, balconies, terraces, steps, landings, paving and other landscape surfacing and any other structures standing on that lot form part of that lot” – the quoted words are taken directly from the registered plan and also written on the plan is “The stratum of each lot is limited to a height of 20 above and a depth of 10 below the upper surface level of the ground floor of the respective residence forming part of that lot…
This does not sound odd to me. It seems like an attempt to define what would be normal ‘class B’ units in the ACT. I am in the middle of a terrace-like set of townhouses. Here my unit (IE ‘lot’) is from the mid-point of the party wall with my neighbour on one side to the mid-point of the wall on the other side. The roof, the walls, the courtyard areas, the balcony are all part of my lot and my responsibility to maintain. The OC takes out an insurance policy for the entire property however so I only need to insure the contents. This is the normal arrangement of townhouse units in the ACT. IE where the strata are arranged side by side we have class B. Where the strata are arranged vertically, one above another, such as a block of flats we have class A and things are more like in NSW.
Extensions are possible if approved by the OC. About 10% of our units have had substantial extensions done.
