With regards to the properties on either side of your property, what is the setback for each property? ie the distance between the front boundary and the respective properties.
Is this more, less or the same as the existing dwelling on your property?
why on earth would you think vcat would get involved?
...I'm not sure, from memory they are a bit closer to the front boundary. This is not mine but something I'm considering buying. Being able to build three units would make this block more attractive to me. How would next door properties affect my plans?
So with the the property dimesions being 16.5 x 45.5, the worst case scenario is that 9m from the front boundary cannot be utilised. Or effectively 148.5sqm (9 x 16.5)
Given 750sqm, you will need all the space to build on three. Of course, it depends on what you intend on building as well, their design, how many bedrooms, garages, surrounding streetscape and the nature of the dwellings around you.
