Granny Flats – Portable, Affordable & Modern Living Solutions
Granny flats in NZ are becoming one of the most practical and cost-effective housing
solutions for homeowners seeking flexibility, independence, and long-term value.
Whether you’re planning a backyard secondary dwelling, exploring portable granny
flats, or taking advantage of the new 70sqm building consent exemption, NZ4U2U
provides compliant, high-quality living solutions delivered across South Island NZ.
What Are Granny Flats?
Granny flats are also known as minor dwellings or secondary residential units. They
are self-contained living spaces built on the same property as an existing home.
In New Zealand, they are commonly used for:
● Multi-generational living
● Rental income opportunities
● Downsizing solutions
● Guest accommodation
● Home office or studio space
Modern granny flats designs include full kitchens, bathrooms, insulation, and double
glazing — delivering comfort comparable to a traditional home, in a smaller footprint.
Portable & Transportable Granny Flats
Portable and transportable granny flats offer unmatched flexibility. Built off-site and
delivered ready for placement, these relocatable homes reduce build time, site
disruption, and overall cost.
Key advantages include:
● Faster installation compared to traditional builds
● Relocatable design if you move properties
● Controlled factory construction quality
● Reduced on-site construction risk
NZ4U2U specialises in transportable granny flats delivered South Island wide,
including Christchurch, Queenstown and beyond.
Granny Flat Cost – What Should You Expect?
One of the most common questions is: How much does a granny flat cost in NZ?
Costs typically depend on:
● Size (commonly 30sqm to 70sqm)
● Level of finish and customisation
● Site preparation and foundations
● Delivery distance
● Council and compliance requirements
Portable granny flats generally offer more predictable pricing compared to traditional
construction. Investing in a secondary dwelling can also increase property value and
create additional income potential.
For tailored pricing, NZ4U2U provides transparent quotes based on your land,
location, and design preferences.
New 70sqm Granny Flat Rules (From January 2026)
From 15 January 2026, new legislation introduced by MBIE allows certain single-
storey, standalone granny flats up to 70sqm to be built without a building consent,
provided strict conditions are met.
Key requirements include:
● Simple design that meets the Building Code
● Work carried out or supervised by Licensed Building Professionals
● A Project Information Memorandum (PIM) must be obtained before
construction
● Council must be notified before work begins and after completion
● All exemption criteria must be satisfied
The exemption operates alongside the National Environmental Standards for
Detached Minor Residential Units (NES-DMRU), which may allow construction
without resource consent if permitted activity standards are met.
This legislative update makes building granny flats more accessible — but
compliance remains essential. NZ4U2U stays up to date with all regulatory
requirements to ensure your project is fully compliant.

Frequently Asked Questions About Granny Flats

building consent exemption if all conditions are met. A PIM is still required, and
council notification obligations apply.
What is the difference between a minor dwelling and a granny flat?
In NZ planning terminology, a minor dwelling or secondary dwelling is often used

Yes. Modern transportable granny flats must meet the New Zealand Building Code,
