Extending your home is a wonderful way to add value to your property, increase the space of your home, or add a room to suit your wants and needs in adverse to the hassle of picking up all your belongings and moving into a completely new house.

Although extending your house is an exciting venture, you should take a moment to take some things into consideration during your design process prior to commencing any construction if you would like to save time, money, and any sentiment of regret.

Council Check

It is mandatory to attain approval from your local council when creating an addition to your home – Including small projects. This will most likely require a Development Application.

The reason why creating an extension to your home requires council approval is because there may be restrictions on:

  • Height and size
  • How close you can build from your property boundary
  • Special buildings and areas, i.e. heritage buildings, environmentally sensitive areas, and bushfire prone areas

Council checks can take over six months to attain planning permission, but with a structural engineer to check and approve your plans beforehand, you are more likely to have your proposed plans approved in a shorter manner of time. This gives your council more confidence in your plan if it has already been checked by a professional and if the structural issues have already been eliminated from your plan.

Expanding Out OR Up

 There are pros and cons to expanding your house outwards or upwards. Expanding your house outwards will consume a portion of your yard space, therefore you need to ensure that you have the space for your extension, or you will need to cut down the size of your extension.

Alternatively, you can add another storey to your house, which could possibly add significant value to your home and save you from compensating your land space. Unfortunately, converting from a single-storey house to a double-storey house is more complicated than extending your home outwards. There is much more structural work and things to consider, such as:

  • Removing and reattaching a roof to the extension
  • Ensuring that your structure can handle the additional loads
  • Scaffolding costs
  • Your overall budget


From an aesthetic perspective, it is optimal that your new extension to your house blends to an extent with your existing house so that it does not stand out so blatantly in comparison to the rest of your home or with the architectural integrity of your neighbourhood. Some ways that you can portray seamlessness throughout your house would be to utilise the same materials such as brick or wood, carpet or tiles, curtains, or doors.
