Residential Flat Building

PROJECT DETAILS | Project Type

A Residential flat building is a building containing 3 or more dwellings on one lot of land.

Examples include apartments, units and boarding houses that have other dwellings above or below, often with shared access and common areas. It does not including attached dwellings or multi dwelling housing.

How do I determine the number of residential flat buildings?

You only need to enter the number of residential flat buildings in the development and not the number of units. On subsequent tabs the building can then be named and the number of dwellings in each building nominated. This breaks the development into separate sections for the purposes of certification and assists the certifier to ensure the relevant commitments are met for that building.

You must follow these guidelines to ensure the building is evaluated correctly by BASIX.

  • Where a unit building is attached to a row of townhouses, enter one unit building and the number of multi-dwelling houses.
  • Where there are more than one unit building on the site enter each as separate buildings, even if the buildings share the same underground facilities such as carpark.
  • Where two unit buildings are attached but are not internally connected, enter each as separate buildings.
  • Where two buildings are internally connected by a walkway but are otherwise effectively separate buildings, enter each as a separate building.
  • Enter a podium with a tower above as one unit building.

If two unit buildings have separate entrances but join above at some point and are internally connected at that point, enter each separately and make a judgement on a logical separation point. This is not critical however it will just assist the certifier with inspecting the building. Unit buildings should be clearly labelled on plans, with separation points indicated.
