Common Questions

Do I need a council permit?

In NSW, outdoor rooms under 20sqm that meet a 1m boundary setback are often classed as exempt development. However, use restrictions apply. Always check with your local council.

Do I need a concrete slab?

No slab is needed. We raise and level a galvanised steel base over most ground types, providing a long-lasting and stable foundation.

How long does installation take?

From the time we receive your deposit, most projects are completed to lockup stage within 1–2 weeks. On-site work typically takes about 1 week.
