How we build your modular granny flat

We discuss your goals, who the space is for, your budget and what you're hoping to achieve on your property.

• Share your suburb, property ownership status, family needs and indicative budget.
• We talk through your chosen model or bespoke design and answer preliminary questions.
• An obligation-free conversation — we provide an indicative proposal before detailed site feasibility.

Once your budget and indicative scope are aligned, a preliminary assessment of access, available space, slope, overlays and utility services.

• We review council mapping, planning zones and secondary dwelling rules.
• Check street access, delivery route clearance and crane reach.
• Identify existing power, water and wastewater connection points.
• Detailed, site-specific investigations follow budget alignment and may incur additional cost.

A detailed, itemised project scope separating the modular building, site-specific costs and chosen upgrades.
