Clear, honest price ranges by size, plus the site and approval costs that catch people out. Then a fixed quote on your actual block, so you can plan with confidence.
The first question almost everyone asks is a fair one. What does a granny flat actually cost in Sydney? It depends on your block and how you finish the home, but the ranges are well understood, and we are happy to lay them out plainly. We have built granny flats across Sydney for over 30 years, so these are the numbers we work with every day.
The base build price is only part of the picture. Most Sydney projects also include:
Roughly $3,000 to $10,000, more if the block slopes or needs clearing.
Water, sewer, power and stormwater, roughly $15,000 to $30,000.
Roughly $5,000 to $11,000 depending on the pathway.
Driveway, paths and landscaping, roughly $8,000 to $23,000.
Sandstone or rock under the surface, and how far services run to the sewer.
See the full sequence on our process page, or compare options in our NSW granny flat cost guide.
For a lot of Sydney owners it does, over time. A second dwelling commonly rents for about $450 to $650 per week depending on size, finish and location, and it can add value to the property as a whole. We run through the numbers in our granny flat investment guide and rental income guide. None of this is financial advice, so check your own situation with your accountant or adviser.
We provide a fixed price contract so you know what you are paying. Clear inclusions and a fixed price are two of the most important things to look for in any builder.
Choosing a standard design, a simpler finish and a flat, easy-access block all keep costs down. A studio or one-bedroom home costs less than a full two-bedroom build.
Approval and certification are usually a separate line item, around $5,000 to $11,000. We help you understand the approval pathway for your block.
