Once you’ve decided to take on a full house renovation, the next question is usually: what does that actually involve? A “whole house” renovation covers a lot more than new paint and a fresh kitchen. Here’s what’s really included, from the structure out.
Short answer: a full house renovation typically covers structural and exterior work (cladding, roofing, glazing), what’s behind the walls (wiring and plumbing), a full interior transformation (kitchen, bathrooms, living spaces), council consent and compliance, and the project management to bring it all together under one roof.
What does a “full” or “whole house” renovation actually cover?
A full renovation is different from a single-room upgrade because it treats the whole home as one project, rather than a series of separate jobs. That scope is also what drives the budget, so it’s worth reading alongside what a whole house renovation costs. Depending on your home’s age and condition, a full renovation generally means:
- Structural and exterior work: cladding, roofing, windows and doors
- Electrical and plumbing throughout the home
- A full interior fit-out: kitchen, bathrooms, living and bedroom spaces
- Council consent for any restricted building work
- One team managing every trade, from start to finish
The structural and exterior work
For older homes especially, the exterior is often where the biggest transformation happens. This can include stripping back to the existing cladding, adding a cavity system for weathertightness, and installing new cladding and roofing, along with replacing single glazing with double glazing throughout.
We recently completed this exact scope on a Lockwood home: we strapped a cavity over the existing aluminium-clad tongue-and-groove cladding, then installed a mix of steel roofing and cladding with James Hardie vertical Oblique cladding, and replaced every window in the home with double glazing. It’s the kind of work that transforms a home’s appearance from the road as much as it improves how it performs.
What’s involved behind the walls
This is the part homeowners see the least of, but it’s often where a full renovation earns its name. Older homes weren’t built to modern electrical or plumbing standards, and problems aren’t always visible until the walls are opened up.
On that same renovation, what started as a planned rewire turned out to be essential rather than optional: the original wiring had been damaged by rats and needed a complete replacement for the home to be safe and the Electricians can issue a Electrical CoC, which will be submitted to council in order to get a code of compliance certificate CCC. Without the full rewire, neither of the certificates would be issued therefore would not get Code of Compliance. It’s a good example of why a full renovation is worth doing properly. Issues like this rarely show up on a pre-renovation inspection, and a partial renovation can leave real risks untouched.
The interior transformation
Inside, a full renovation typically covers:
- Kitchen renovation, usually the most visible and valued space in the home
- Bathroom and ensuite renovation
- Living, dining and bedroom spaces, including layout changes, flooring, and finishing
- Insulation and interior linings, especially where walls have been opened up for wiring or plumbing
Because everything is being renovated together, finishes and layout decisions can be made to work as one cohesive home, rather than a patchwork of different eras.
Council consent and compliance
Any structural or weathertightness work, such as new cladding, moved walls, new windows, or a rewire of this scale, is restricted building work under New Zealand law, and has to be signed off by a Licensed Building Practitioner (LBP). This is one of the areas where DIY or an unlicensed handyman simply can’t help you, and where a compliance shortcut now can become a very expensive problem when you come to sell.
How The Reno Guys manage the whole process for you
A full house renovation touches almost every trade: builders, electricians, plumbers, roofers, glaziers, and more. Coordinating all of that yourself is where most of the stress in a renovation comes from. We manage the entire project end-to-end, with one point of contact, all trades scheduled and coordinated, and clear communication throughout, so you’re not the one chasing people to turn up.
How long does a full house renovation take?
Timelines vary with scope, but a full structural renovation covering recladding, rewiring, and a complete interior overhaul is a matter of months rather than weeks, particularly on remote or rural sites where access and weather can affect scheduling. We’ll give you a realistic timeline as part of your quote, based on your home and site specifically.
