Understanding House Extension Costs Committed to building sustainable, energy-efficient homes
When planning a house extension, understanding the costs involved is crucial. Various factors, such as the type of extension, design complexity, materials, and labor costs can all affect the final price.
Type of Extension
- Single-Storey Extensions
- Double-Storey Extensions
- Garage Conversions
- Second-Storey Additions
Design and Materials
Your choice of custom design and materials will also impact the cost. High-quality finishes and sustainable building options may come with a higher price tag, but they will ensure the long-term durability of your extension.
Site Preparation
If your site requires extensive preparation, such as excavation or the removal of trees, this can also add to the overall cost of your extension.

Types of House Extensions
We specialize in all types of extensions and renovations, helping you find the right solution based on your needs and budget. Here’s an overview of the most common types of house extensions we offer in Melbourne:
-
Single-Storey Extension
For homeowners looking for cost-effective solutions, single-storey house extensions are an excellent option. These are ideal for adding extra space to your living area, such as a new kitchen, bathroom, or lounge room.
-
Double-Storey Extensions
Double-storey extensions are perfect if you need to create more space but don’t want to take up more land. By building upwards, you can add more space without compromising your yard or garden area.
-
Garage Conversions
If your garage is underutilized, a garage conversion could be the ideal solution. This cost-effective option allows you to repurpose the space into a home office, guest room, or living room.
-
Second-Storey Additions
A second-storey addition allows you to expand your home vertically, which is perfect if you need extra space but don’t have the luxury of expanding outwards.
