New prefab vs used relocatable homes in NZ: the pros and cons
New prefab vs used relocatable homes in NZ: the pros and cons
Are you a home buyer, owner or developer in New Zealand? Chances are, you’ve considered building a prefab home or buying a relocatable one – whether it’s to live in or as an investment.
So what’s the real difference between prefab homes and relocatable (or transportable) homes? More specifically, new prefab builds and used relocatable houses? And how do you know which option is right for you?
In this guide, we’ll unpack the key differences, together with the pros and cons of each. It’s the ideal tool to help you decide which one works best for your budget, lifestyle and goals.
What are new prefab homes?
Prefab (prefabricated) homes are built offsite. Once completed, they are transported to site by truck, where they are installed on permanent foundations.
At Advance Build, this construction process happens inside a controlled factory environment, eliminating weather delays and maintaining consistently high standards.
Advance Build’s streamlined factory process gives you:
- Cost-certainty
- Quality control
- Guaranteed move-in date
- Hassle-free process
- Customisable designs.
All backed by a reputable company with 16+ years in the industry.
What are used transportable homes?
Used transportable (or relocatable) homes are older existing houses that have moved from one site to another. They differ from new prefab homes because they have already been lived in.
Prefab homes, on the other hand, are newly built before being transported to a site for permanent installation.
Typically, used relocatable homes:
- Have been lived-in
- Require transport and reinstallation
- Often need renovation to meet building codes and modern living standards.
Key considerations of used relocatable homes
Thinking about buying a used transportable home in New Zealand? Here are a few things to check first:
- Condition + maintenance – Used transportable homes often show wear and tear, so make sure you inspect the structure carefully. Hidden damage can quickly turn into expensive repairs.
- Building code compliance – Older homes may not meet New Zealand Building Code standards. Before you commit, check whether you need to organise upgrades or new consents to comply.
- Transport + installation costs – Permits, transport and site preparation costs all add up. Know your numbers first!
- Renovation + restoration costs – Relocatable homes often need upgrades (e.g. new plumbing, wiring or insulation). Get quotes early to avoid budget surprises.
- Long-term durability – Relocating homes that aren’t designed to be moved can impact the structural integrity of transportable homes. It’s worth considering how it will perform long-term compared to a new prefab build.
What is the difference between prefab homes and relocatable homes?
When comparing new prefab homes vs used relocatable homes, it’s helpful to look at how each is built, delivered and designed. Here’s a breakdown of those factors and what they mean for cost, quality and longevity.
| Factor | New prefab homes | Used relocatable homes |
| Build process | Built brand new in a controlled factory environment. This ensures precision, consistency and time-certainty. | Existing homes are transported to another site. As older buildings, they may already be showing signs of damage – which can worsen during the move. |
| Design | Modern, functional layouts designed for today’s lifestyles. | Older layouts that may feel dated or need upgrades to suit your needs. |
| Delivery | Delivered to site once completed at the factory. Purpose-built to withstand the move, so minimal risk of damage during the transportation process. | Lifted, transported and reinstalled on new site. Not specifically designed for moving, so more prone to damage during the relocation process. |
| Customisation | Fully customisable. Choose finishes, layouts and materials to suit your style and budget – e.g. add old villa-style charm with cabinetry, trims and classic fixtures. | Limited flexibility – you’re adapting an existing home, rather than designing from scratch. |
| Cost | Higher cost because the house is brand new. At Advance Build, these costs are predictable and all-inclusive. | Lower initial purchase price, but potential for higher transport, repair and compliance costs. Often hard to manage and budget for. |
| Lifespan | Brand new buildings give you long-term durability and low maintenance living. | Shorter remaining lifespan (depending on your home’s age, materials and existing condition). |
The pros and cons of new prefab vs used relocatable
Tips from someone who’s been there
When Dave opted for a used relocatable home, he ended up experiencing an ‘absolute headache nightmare.’ He says new prefab homes are a far simpler, cost-certain approach to building.
‘It’s cost effective and time effective, with no variation or anything to be unsure about,’ he explains.
So, what are the pros and cons of prefab and transportable homes? Let’s take a closer look.
New prefab homes
New prefab homes in New Zealand are purpose-built for modern living, offering quality and efficiency from the start. Here’s what to consider.
The pros of new prefab homes
- Brand new – Every part of your home is built to the latest New Zealand building standards using modern materials and energy-efficient design.
- Customisable – Choose your layout, colours, fixtures and finishes.
- Cost-certain – Turnkey pricing means you know your total cost upfront (no hidden extras or surprises along the way).
- Warranty – Advance Build homes come with a 10-year warranty on workmanship and materials, plus a 1-year defects and remedials period.
- Hassle-free – One dedicated, experienced team handles everything so you don’t have to.
The cons of new prefab homes
- Higher upfront cost – The initial price is higher than a used home. However, long-term costs are lower once you factor in fewer repairs, renovations and delays.
💡Dave’s top tip
Don’t struggle through processes you aren’t familiar with, Dave advises.
‘When you’re self-managing a secondhand relocatable project, there are lots of these small things that would generally be caught by Advance Build.’
Used relocatable homes
Used relocatable homes can appear to be an easy accommodation solution – but they come with a few catches. Here’s what to weigh up first.
The pros of used relocatable homes
- Lower purchase price – Usually less expensive upfront than buying new.
- Character and charm – Many relocatable homes are classic villas or bungalows and feature period features that add instant appeal.
- Availability – Because the house already exists, you can move faster from purchase to site placement.
The cons of used relocatable homes
- Wear and tear – Older homes often need repairs or upgrades before you can move in.
- Renovation and compliance costs – Bringing an older home up to current New Zealand Building Code standards can add significant time and expense.
- Hidden / unforeseen expenses – From damaged framing to outdated wiring, surprises can quickly increase total costs.
- Transport risks – A home that’s not designed to be moved increases the risk of cracking or structural damage. This then needs fixing once onsite.
- Project management – Unlike a turnkey prefab build, you’ll need to coordinate movers, builders, trades and councils yourself.
💡Dave’s top tip
He says to look beyond the (often attractive) sale price of a used relocatable home and understand the potential costs.
‘Generally after a house has been relocated, it requires a full renovation anyway…your actual final cost is almost impossible to forecast…we went $500,000 over our project [budget].’
Should I buy a used transportable home or a new prefab?
That question depends on your goals, budget – and how hands-on you want to be with the process.
If you want a modern, low-maintenance home with cost-certainty and minimal hassle, a new prefab home is your best bet.
Prefab homes are:
- Built for long-term living
- Designed to meet current New Zealand Building Code standards
- Able to be relocated in the future (with some planning and effort).
On the other hand if you’re drawn to character homes and don’t mind some renovation and project management, a used transportable home might appeal. These can be found across regions like Northland, Waikato and Taranaki – but keep in mind that each project can bring unique challenges and variable costs.
