First Floor Additions

Expand living space vertically with custom-designed first-floor additions.

We cannot speak more highly of Nick and the Addspace Team! We added an additional bedroom and living area in the Inner West all whilst working from home & home schooling 2 kids and I still can't fault the process. The quality of the work is great, Nick and the team assisted with everything from design through to DA approval and communication was top notch. Our neighbours commented on how respectful and nice the team were and that included any contractors Nick engaged. We were on time, on budget and even got another mini project (built in bbq area) snuck in the mix. We are loving our new space

2 storey Rear extension - highly recommended
We wanted to renovate our home in the inner west for quite some time and sought many quotes. Chose Add Space for design and build services and we are so happy that we did - from start to live-in.
Nick and his design team are quick and thorough in communication, not leaving you waiting for an answer. Great management and expertise from Add Space - from a brutal council process to various contractors to after care.
Nick's build team are also phenomenal, and my neighbours were so impressed with how respectful they were on-site.
Renovation was efficient

Cant thank Nick and the add space team enough for the phenomenal job they did with our attic renovation. Nick transformed the space into a spare bedroom, lounge area and bathroom and we are so incredibly happy how this project has turned out. Nick guided us through the whole process, had open and regular communication to keep us up to date with the project and organised everything from start to finish. Would highly recommend addspace to everyone!!!
