Real Estates Fees



Real Estate Fees — There are many unwanted fees associated with buying and selling property. When it comes to selling, styling your home, if necessary, can cost up to $6,000. Then there’s the marketing, which depending on your budget, can cost anywhere from $1,000 to $10,000. Just when you think that’s everything, there may be an auction fee of $400 to $1,000—on top of the real estate agent’s overall 2% commission. Based on the Melbourne median house price of $918,000, this could be approximately $18,000.

Conveyancing Fees



Conveyancing Fees — Conveyancing fees can vary, you can expect to pay anything from $800 to $2,000. Not too much in the grand scheme of things, but it all adds up.

Stamp Duty



Stamp Duty — Based on the Melbourne average house price of $918,000, you will be charged Stamp Duty of approximately $50,000. Stamp Duty Fees fluctuate, depending on:

  • Where you live in Australia

  • The type of property you are purchasing

  • If you are a first home buyer or not

  • Whether you are purchasing a vacant land, new home or established home

  • If you are a foreign purchaser

Moving Costs



Moving Costs — Don’t forget the ‘big move’ can be costly too. If you choose to do it yourself, hiring a van or a truck for a day can cost $200. Or, engaging a team of professional removalists (which is often a wise choice) is likely to cost around $2,000.



By deciding not to move, that’s a potential saving of approximately $89,000 to re-invest and put towards improving your current home.

How much does
a second storey
addition cost?

When comparing pricing on a second storey addition in Melbourne, it is important not to go by price per square metre. There are three main reasons for this:

1. Quality can vary immensely — It is important to remember that not every second storey extension builder in Melbourne delivers a project to the same standard. Materials, finishes and execution vary in quality, and therefore in price too.


2. Every project is different — Depending on the scale and complexity, and the areas involved in the new double story addition, price per square metre will vary. Designs featuring unusual shapes and angles will, naturally, be more expensive than designs with simple square shapes. This is due to the extra building materials required, rather than any added difficulty in the execution. kitchens and bathrooms will also increase the cost of the two storey extension significantly. The average cost of a kitchen ranges from $30,000 to $75,000, and a bathroom from $20,000 to $40,000. The overall costs of a second storey addition, without rooms such as these, will be considerably less than one with.


3. Every property is different — Often, the existing home will need upgrading to suit the new second storey addition. The design of the 2nd storey extension, and the way it integrates into the existing structure will ultimately dictate the extent to which the ground floor will need to be upgraded. Other factors such as council overlays, energy efficiency, bushfire zones and soil classification have the potential to impact the overall cost of the project and affect the cost per square metre.


On average, the cost of a second storey addition begins at approximately $250,000. As third-generation extension builders, the Team at XL Built harness 45 years of experience to assess and quote a project as accurately as possible. With excellent communication and foresight, XL Built will work with you throughout the build to ensure any additional costs are minimised and managed.
