When a referral agency becomes involved in your assessment process for your development application, it can result in unexpected costs, unplanned re-designs, and delays for your application approval. All of which can significantly affect your proposed development. To prevent such frustrations talk to your town planner or building certifier and determine if a referral is required before you submit your application. Here is The Oil Stone’s brief explanation on Referral Agencies.
Exempt, self-assessable, assessable, compliance, prohibited. All these words refer to development approval categories in Queensland, and it is essential to know which category your project belongs to before you begin planning. So how do you determine which category, and how will the result affect your proposed development? Here is The Oil Stone’s brief explanation.
We need to talk about separating walls and what the building certifier means when they refer to separating walls. Separating walls are essential to protect against noise and fire, but choosing the right installation or modifying an older system, can seem quite a daunting task. Here is The Oil Stone’s quick discussion.
Class 1a Dwelling Units
Class 1a Dwelling units have a separating wall between each dwelling unit that extends continuously from the ground to the underside of the roof of the units.
Class 1 buildings cannot be built on top of each other, and each is totally independent of the adjoining class 1a except they share a separating wall.
Please note I did not use the term fire wall. Separating walls function as fire separation, however, they are not fire walls as defined in the BCA Volume 1.
Class 2 Dwelling Units
Class 2 dwelling units are not independent of each other like Class 1a buildings. They can share entries, hallways and roof space, or be built on top of each other.
In a Class 2 Dwelling, the space contained within the floor, walls and ceiling of the dwelling unit, is separated from the other common parts of the building or other Class 2 Dwellings. The separation is achieved by constructing the bounding floor, walls, and ceilings of the dwelling to comply with the required fire, sound, impact and insulation ratings.
Please note I did not use the term fire walls or separating walls. Class 2 buildings do not use fire walls or separating walls to separate dwelling units.
