If you have a large section with a poorly located house on it and are looking at re-development opportunities, an On-site Shift should be considered.
On-site Shifts involve lifting and shifting the original dwelling and relocating it to achieve a better section layout, freeing up land for extensions, subdivision, a minor dwelling, garage or landscaping.
This is a great option to increase the equity and value of your land. Other options include demolishing and building new, however there are considerable costs involved here for what could be a similar outcome.
