Dual occupancy homes can be designed in all sorts of ways, depending on the owner’s specific needs and preferences, layout of the developed land, and several other factors. A big question that often pops up during planning and design, however, is whether or not they require a partition wall between the two homes.
The Short Answer: Yes, a Partition Wall is Necessary
Your dual occupancy home requires a partition wall provided that both properties are attached to one another. If your dual occupancy homes are physically separated, no partition wall is necessary.
Many dual occupancy homes are designed to be attached, and in these circumstances an engineered partition wall is needed to comply with Australian building codes related to structural integrity and fire safety.
Is the Partition Wall any Different from Ordinary Internal Partition Walls?
Yes. The partition wall used between dual occupancy homes is different from ordinary partition walls commonly used in buildings. Simple partitions are not load-bearing and often make little difference in fire safety or thermal or sound insulation, but the partition wall used between dual occupancy homes must meet certain standards outlined in the National Construction Code.
The most important consideration is for fire resistance, and the wall must meet a specific fire resistance level whereby, in the event of a fire, the spread is slowed as much as possible.
Moreover, the wall must provide some degree of acoustic insulation. Both dwellings will have separate tenants, so they must each have sufficient privacy.
How is the Partition Wall Built?
The dual wall required for attached dual occupancy homes is typically built with similar materials used in the overall home construction, i.e. either timber framing or block masonry.
For timber frame construction, the partition wall may be built with timber as well or it may be built with steel framing. The wall is lined with fire-rated boards and insulated with acoustic batting.
For block masonry construction, the partition wall may be built using concrete blocks or double brick. These materials are naturally quite excellent for acoustic performance and deliver fire resistance.
Privacy is Essential
Fire resistance is the most important aspect of a partition wall, but for practical purposes beyond fire safety, privacy is usually the biggest concern for tenants of both units.
Poor acoustic performance can lead to tenants hearing all sorts of things from their neighbours, and if you are a landlord with both units let to tenants, this can lead to disputes and vacancies. The disruption simply isn’t worth it, so make sure that your units are sufficiently separated with a partition wall that provides privacy.
Comfort and tranquillity are what tenants rightfully should be looking for when renting your dual occupancy home. These are not always guaranteed from an apartment unit, but with a dual occupancy home there is more of an expectation that tenants will have a little more privacy and comfort. Don’t overlook the importance of the partition wall.
How to Design a Dual Occupancy Home that Maximises Privacy and Safety
The partition wall is an important element of dual occupancy home design and construction that should not be neglected. When it is necessary, it must comply with Australian building standards and regulations.
