What does it cost?
Basement conversions with Refresh Renovations Auckland Central typically start from around $75,000*. Where costs move beyond that depends on factors like council requirements, waterproofing, soundproofing, and structural work, all of which vary a lot from home to home. This estimate also doesn't cover excavating and building a brand new basement from scratch, that's a different scope entirely. Your Renovation Consultant will give you a firm cost estimate before any construction begins, and if you're working to a tighter budget, they can help find cost-effective ways to get there without cutting corners on quality.
*Ballpark estimate only, subject to change based on your specific project.
What to think about before you convert
Every basement conversion raises a similar set of questions: how people will get in and out of the space, how it'll be soundproofed and insulated, where plumbing needs to run, how the layout should work, and what council will require before you can start. Your consultant walks through all of this with you at the design stage, alongside your own style preferences, so there are no surprises once construction starts.
How it works
1. Initial Consultation: A local consultant visits your home to understand the space and what you want from it.
2. Scoping and Feasibility: We assess access, structure, and site conditions to confirm what's realistic.
3. Detailed Planning and Costing: Full design and a firm cost estimate before anything is locked in.
4. Build Stage: Construction managed start to finish by your dedicated project manager.
5. Project Completion: Final walkthrough and handover.
One Renovation Consultant stays with you the whole way, so you're never juggling multiple trades or chasing updates yourself.
