Transportable Home Building Terms Explained: A Plain-English Glossary for NZ Buyers

Building a new home throws a surprising amount of jargon at you. Consents, geotech, civil works, CCC, turn-key, the list goes on, and most of it is never properly explained. For a first-home buyer especially, that language can make the whole process feel more complicated and more risky than it actually is.

This plain-English guide clears that up. It walks through the transportable home terminology you are most likely to meet, grouped by the stage of the journey where it comes up, so understanding building terms stops being a source of anxiety and starts being something that gives you confidence. You can see how these stages fit together on our process page.

Ballpark. The realistic early estimate we give you after our first meeting, once we understand your section, your chosen plan, and any changes. It is not a fixed price; it is an honest indication of what your project is likely to cost so you can plan before committing.  

Concept design. The stage where your home takes shape on paper. You work through layouts, materials, and key features so the design suits how you live, looks the way you want, and fits your budget.

Preliminary building contract. The stage that removes the unknowns. Before any fixed price is set, we complete the engineering, surveying, and council discussions needed to confirm exactly what can be built on your site. This is where guesswork is replaced with certainty.

Fixed-price building contract. Exactly what it sounds like. Once the design, approvals, and technical details are confirmed, we provide a contract with a locked-in price, scope, and timeline. From there, the number does not move, right down to the small details.

Turn-key. A complete service where we manage everything from consents and site works to delivery and final connections, and hand you the keys to a finished home. You are not coordinating trades or chasing council yourself.

Geotechnical report (geotech). An assessment of your ground: how stable it is, how it drains, and what kind of foundations it needs. Ordering a geotech report early is one of the best ways to avoid surprises later, because it tells us how your land actually behaves before anything is built. If you have been reading about a geotechnical report NZ councils commonly ask for, this is it.

Surveying. The work that confirms your boundaries and pinpoints exactly where your home can legally and practically sit on your section. It ensures the home is positioned correctly and complies with the rules that apply to your site.

Stormwater assessment. A check of how rainwater will drain from your site and your new home, and where it will go. Councils want to know stormwater is managed properly, and this assessment provides that answer.

Civil works and site works. The physical preparation of your land so it is ready to receive your home: earthworks, foundations, access, and drainage. When people talk about civil works NZ wide, this groundwork is what they mean, and on a turn-key Exeter build it runs in parallel with your home being built in our yard, which saves time.

Foundations. The base your home is placed and secured on. The right foundation type depends on your ground conditions, which is exactly why the geotech report comes first. 

Building consent. Formal approval that confirms your building work meets the New Zealand Building Code. A transportable home in New Zealand actually involves two separate building consents, which is a detail that surprises a lot of buyers.

Yard Building Consent. The first of the two, and one we take care of. It allows us to build your home in our Rotorua yard. You do not need to do anything here; it is part of how we work.

Local Building Consent. The second consent, which goes through your local council and allows the home to be moved onto and connected up on your site. This is the one tied to your specific piece of land.

Draughtsman. The person who prepares the drawings for your Local Building Consent, showing where the home sits on your section and how it connects to services. Because every council has slightly different rules, working with someone in your area helps everything go smoothly. Councils usually need at least 20 working days to process a consent application.

Code Compliance Certificate (CCC). The council’s formal sign-off, issued once the completed work has been inspected and confirmed to meet the building consent. It is the document that says your home is officially compliant and complete.

Healthy Homes Standards. New Zealand’s minimum standards for heating, insulation, ventilation, moisture, and draughts, particularly important for rentals. Every Exeter home, right down to our entry-level range, is built to meet them.

For the questions buyers ask most often about consents, compliance, and what is included, our FAQs page is a useful next stop.

Double glazing and thermally broken joinery. Double glazing means two panes of glass with a gap between them, which keeps heat in and cold out. Thermally broken aluminium joinery adds an insulating barrier within the window frame itself, reducing condensation and heat loss. We use double-glazed, thermally broken joinery as standard across Exeter homes, as part of meeting the Healthy Homes Standards. 

Cladding. The exterior skin of your home, the weatherproof layer that protects the structure underneath. It also gives your home much of its feel: we use durable fibre-cement products that can look like weatherboard, schist, brick, concrete, or timber-grain, paired with a Coloursteel roof and chosen to stand up to the New Zealand climate with minimal maintenance. 

Minor dwelling and granny flat. A minor dwelling is a smaller, self-contained second home on the same section as a main house. It is often called a granny flat, and recent rule changes have made these easier to add in many areas. A transportable home can make an excellent minor dwelling.

Ready for site connection. You will see this next to plumbing and electrical. It means the home is fully wired and plumbed internally and simply needs to be joined to your site services once it is placed. It is a normal, expected part of the delivery stage, not an extra you have forgotten.

Delivery and placement. The day your finished home is transported from our Rotorua yard to your site and positioned on its foundations. We arrange and oversee the entire process, including the transport logistics, so you do not have to.

Service connections. Hooking your home up to power, water, and drainage. Some of this involves third parties whose timeframes we coordinate on your behalf.

Finishing touches. The final works are completed once your home is in place, such as lawns, landscaping, and letterboxes, so it is genuinely ready to live in when we hand over the keys. 

Handover. The moment the keys are yours. And with Exeter, support does not stop there; our team stays available for questions as you settle in.

None of these terms are as complicated as they first sound, and a builder who is happy to explain them plainly is usually a builder worth trusting. Jargon should never be used to keep you in the dark or to gloss over costs. The more clearly you understand the process, the more confident you can be in the decisions you are making.
