Approvals

Most serious projects should be checked against council, certifier and site requirements before money is spent.

Costs

Base prices rarely tell the whole story. Services, site works, transport and approvals can change the budget.

Next steps

If you are unsure, send the location and intended use first. That makes the next conversation much clearer.

Common questions

Do I need council approval for a granny flat?

It depends on the property, council area, zoning, size, use and final design. Many projects require some form of building approval, certification or council-related check before work starts.

Can I rent out a granny flat?

Rental rules can depend on local planning rules, property setup and the way the building is approved. Check this early if rental income is the main reason for the project.

What is the difference between a granny flat, modular home and container home?

A granny flat usually refers to a secondary dwelling on a property. Modular homes are built in sections or modules. Container homes use shipping containers as the main structure or design base. Approval and site questions can still apply to all of them.

Can you help with finance or return on investment?

Start with the Finance and ROI Calculator. It helps compare repayments, possible rent, cashflow and the extra costs people often forget.

What costs should I allow beyond the building price?

Allow for approvals, drawings, engineering, soil or site reports, foundations, services, plumbing, electrical, water connection, septic if needed, delivery, crane access, decks, stairs and finishing items.

Can I buy floor plans only?

Yes, you can start by comparing granny flat floor plans and shipping container house plans. Check the site and approval pathway before relying on a plan for construction.

Do container homes need approvals?

Often, yes. A container building still needs to be suitable for the site, intended use, engineering, services and local approval pathway.

What information should I provide for a quote?

Send the address, suburb, state, postcode, intended use, preferred size, timing, photos of access and any known issues such as slope, trees, septic, easements, flood or bushfire risk.

Can you supply 20ft or 40ft offices?

Office and studio enquiries can start from the 20ft and 40ft Container Offices page. Delivery, access and fitout details matter before final pricing.

Are digital guides refundable?

Digital guides and courses are usually delivered instantly, so access and product problems are handled under the Refund Policy. Warranty and general terms are outlined on the Warranty and Terms page.
