We’ve compiled the most common questions about Custom Homes, Knock Down Rebuilds, and our building process to provide immediate clarity and transparency.
Cost plus construction is a building contract where you pay the actual cost of labour, materials, and subcontractors, plus an agreed builder’s margin. Unlike a fixed price contract, the final cost reflects exactly what was spent — with full transparency at every stage.
A fixed price contract locks in a total build cost upfront. A cost plus contract means you pay actual costs plus the builder’s margin. Fixed price suits clients wanting budget certainty. Cost plus suits clients wanting premium finishes, design flexibility, or building on complex sites where costs are difficult to estimate accurately.
Not necessarily. Fixed price contracts often include contingency buffers to protect the builder from cost increases. With cost plus, if materials come in under budget, you benefit directly. The key is choosing a builder you trust to manage costs efficiently and transparently on your behalf.
With Ozzie Dream Homes, cost plus contracts include full open book access — you can see all invoices, supplier quotes, and receipts. We get competitive quotes from subcontractors and pass savings directly to you. Our agreed margin is fixed and transparent from the outset.
A cost plus contract covers all direct construction costs — materials, labour, subcontractor fees, council fees, inspections, and site-related costs. The builder’s margin is charged on top of these actual costs. Ozzie Dream Homes provides a detailed cost schedule at the start so you understand exactly what’s covered.
Yes — full transparency is a core principle of cost plus contracting with Ozzie Dream Homes. You receive access to all invoices, receipts, and subcontractor quotes. Regular cost reports are provided throughout the build so you always know where you stand against budget.
Cost plus is particularly well-suited to complex or high-end custom builds, difficult sites, or projects with evolving designs. If your project involves premium finishes, significant site challenges, or you’d like flexibility to upgrade materials during construction, cost plus may be the right approach.
Our management fee is agreed and fixed before construction begins — there are no surprises. The exact percentage depends on the project’s size and complexity. Contact us for a consultation and we’ll provide full details of our cost plus fee structure upfront.
