Why Choose Sure Space
Here's what sets us apart.

Working with Master Builder Darren Long, who is qualified by the Master Builders Association of NSW, means superior knowledge and craftsmanship you can rely on.
-
No curveballs. No unpleasant surprises. No rushed work. Just honest, seamless, and exceptional work every step of the way — from the very first consultation to the final finishing touches.
-
Our team started as shop fitters and joiners, creating beautiful and detailed furniture, beautiful restaurants and luxury stores. The same level of detail brought to boutique fit-outs is now available for your home.
-
Building your home with Sure Space means you’re working with the same team from start to finish. We’ve developed our systems and processes around you, the client, with the highest aim of raising industry standards — and that means delighting you from start to finish.
-
We’re big enough to get savings from our suppliers that we pass on to you, but small enough to care about every single job we take on.
-
We too are sick of blokes in our industry who leave clients hanging. That’s just unacceptable. At Sure Space, you are always informed of our progress and your burning questions answered.

Thank you for your hard work this year building our dream home in Glebe.
We are delighted with the outcome and found you and your trades to be professional and easy to talk to. The challenging site and audacious design was no match for your team. I have no hesitation in recommending Sure Space to anyone looking to renovate or build.
