What is the standard garage size for 4 cars?

12 x 7.5 m with 3.0–3.6 m eave height suits most owners. Larger vehicles or a boat? Stretch to 14 x 8 m.

Most residential 4 car garages sit on a 100–125 mm reinforced slab with thickened edge beams or piers per engineering. Gravel bases are more common on rural machinery sheds but are not ideal for garages.

What’s faster: DIY or turnkey?

DIY saves on labour, but turnkey supply-and-install shortens approvals, coordinates contractors, and delivers a single point of warranty—ideal for property investors and time-poor tradies.

Can I add a carport later?

Yes. Many owners add a flat-roof carport as shaded overflow. Pre-plan gutter fall, posts, and roof alignment.

What about a 4 car shed vs 4 car garage?

In industry speak, 'garage' implies secure, door-enclosed parking; 'shed' covers broader uses such as farm machinery storage, workshop, or hobby space. Engineering and approvals are often identical.
