...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?
Obvisouly check with Glen Eira Council, but the wording for Res Zone 1 development states various standards for building and development (Standard A3 & B6)
In a development context, where there is an existing building on both sides of your block, and the site is not on a corner, then setback is
the average distance of the setbacks of the front walls of the existing buildings on the abutting allotments facing the front street or 9 metres, whichever is the lesser.
So depending on the setback of the adjoining properties, will influence how far back you can start building from. The closer to the front boundary they are, the better for you (in the development context). 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.
