Consumer Affairs Victoria published a series of what you need to consider from different aspects when you want to do some home improvements and small works.
It contains checklists and guidelines which helps you understand the whole process and in case of needing any help, there are some good resources there too.
You can go to http://www.consumer.vic.gov.au/housing-and-accommodation/building-and-renovating/types-of-home-building-projects/home-improvements-and-small-works to get some more information.
At Designs Plus, we proud to help Victorians for their home improvement needs. To see the full list of our service you can visit our Service page or give us a ring and we can explain it to you.
