Know What You're Getting Into... Before You Extend

Feasibility-first advice for homeowners planning an extension who want clarity on cost, approvals, and long-term value before committing.

Planning a Home Extension? Start with Strategy, Not Assumptions​

Extending your home can solve space problems, but only if it’s planned properly. Before you add rooms or draw up plans, there are some critical questions to answer.

  • Will council approve what you’re planning?
  • Can your existing home handle the structural changes?
  • Is extending better value than moving?
  • What will this actually cost? And what are the risks?


A feasibility-first approach helps you understand what’s genuinely possible on your block, what it will cost, and whether an extension is the smartest long-term move for your family.

Talk to ROI Projects first. A clear strategy early on makes it easier to carry the right decisions through design, approvals, and construction.

Many extension projects run into trouble long before construction begins. Early assumptions often don’t hold up through design, approvals, and delivery.

Without a clear pathway, costs creep, timelines slip, and compromises appear where they weren’t expected.

Discover How We Assess Your Project

A real example of the feasibility framework we use to test cost, risk, approvals, and value before any design or construction decisions are locked in.

If you’re already planning to extend, the most important decisions happen before drawings, quotes, or builder contracts.

This sample feasibility report shows how we assess projects at the very start.

What’s viable. What adds value. Where risks sit. And what needs to be resolved early to avoid costly mistakes later.

It’s not a checklist or a sales brochure.

It’s a real-world example of how we think and how we plan.

Worried About Disruption, Delays or Budget Blowouts?

Home extensions can be disruptive if they’re not carefully planned and staged, particularly when you’re living in the house during the work. Approvals, staging, budgets, and timelines all need to align.

That’s why we guide you through each step, starting with clear planning and, if you choose, continuing through to completion.

You stay in control. We handle the complexity.
