House Extensions Coburg: Redefine your Dream Home

You might like Coburg for its multiculturalism and many places to eat from various locations around the world. Or perhaps you like Coburg because of its proximity to Brunswick and its more relaxed suburban feel. You might also like Coburg because it’s so close to Merri Creek, with lots of walking and biking trails for kids and adults alike. There are so many reasons to enjoy Coburg, including the fact that its shops are affordable and the people are friendly. For all these reasons, you may really want to stay in this suburb rather than move away. But what do you do when you’re running out of room in your home? What if you can’t afford to buy a bigger house in the same neighbourhood? That’s where house extensions in Coburg come in.  As home extension builders of distinction, Extensions Unlimited has been building home extensions in Coburg for over since 1994.
