Haven range · Kitset granny flats
Three designs, all sized to fit the 70m² rule.
A kitset minor dwelling arrives flat packed and is set up on your section in about a week, not months. It goes where a crane can't, and you get more say in the plan. All three designs are 70m² or under, which is the size limit for building without a building consent.
SleekHaven 50 · 2 bedroom
Two double bedrooms either side of the bathroom, and one long open room for kitchen, dining and living. Room for a couple, a small family, or two flatmates.
From $204,990
All-in, incl GST, for a standard install in Auckland. Sloping or hard-access sites, and other regions, are quoted for your address.
Includes a Haier appliance pack (cooktop, oven, rangehood and dishwasher) for the first 10 orders, until 31 December 2026.

Why people build them
Six reasons a granny flat makes sense right now
Family, rental income, working from home, and the 2026 rules.
Why people build them
Six reasons a granny flat makes sense right now
Family, rental income, working from home, and the 2026 rules.
A parent, close but independent
The original reason for the name. Mum or Dad on the same section, with their own front door, kitchen and bathroom, and family a few steps away when it matters.
Rental income from land you already own
A self-contained one or two bedroom home rents at a real number in every main centre. The table below shows what that looks like where you are.
Adult kids who can't yet buy
Their own place at a rent that lets them save, without the two households living on top of each other.
Working from home properly
An office that is not the dining table, that can become a rental or a flat for family later.
Value added to the property
A compliant second dwelling with a full document pack is an asset a valuer and a buyer can both count.
Faster and simpler since 2026
Under 70m² and inside the conditions, there is no building consent, so the wait and the consent fees go, and a kitset arrives while the site is being prepared.

Indicative ranges for a new, self-contained dwelling, as at September 2026. Actual rent depends on the suburb, the finish and the market at the time. Gross yield uses the Auckland from price incl GST for a standard install; other regions carry delivery charges. Not financial advice.

Council charges
The size you pick changes what you pay council
Why 65m² and 70m² are both lines worth knowing about.
Council charges
The size you pick changes what you pay council
Why 65m² and 70m² are both lines worth knowing about.
Up to 65m²
SleekHaven 37 and 50
Inside the exemption size limit, and in Auckland usually inside the smaller band for council and Watercare charges. We check the charges for your address.
66 to 70m²
SleekHaven 70
Still inside the exemption size limit. Council charges can step up at this size, so we show you that number before you choose.
Over 70m²
Needs a consent
Outside the exemption. A standard building consent applies, which adds time and cost. We run it for you.

Asked most often
Are the prices all-in?
Yes, for a standard install. Each Haven price is the from price for the home delivered, built and connected in Auckland on a flat site with normal access, including GST, the PIM and paperwork. Sloping or hard-access sites, and addresses outside Auckland, are quoted for your section after the site check, and the number you sign is the number you pay.
What is the Haier appliance pack?
The first 10 Haven orders placed before 31 December 2026 include a Haier cooktop, oven, rangehood and dishwasher at no extra cost. It is confirmed in writing on your quote.
Exempt from consent. Is it exempt from the Building Code?
No, and it does not need to be. Our Haven plans are designed in New Zealand to the New Zealand Building Code, and the build is carried out or supervised by Licensed Building Practitioners. Exempt from consent means council does not inspect it. It does not mean the standard drops, and ours does not.
Do I still have to deal with council?
Not if you would rather not. Council needs a project information memorandum (PIM) application before work starts and the completion documents afterwards. With your permission we prepare and submit all of it on your behalf, and hand you the copies for your records.
There is no code compliance certificate. What is my proof?
Council does not inspect exempt work, so it does not issue a CCC. Your proof is the document pack: final plans, records of work, certificates of work, and electrical and gas certificates. Banks and insurers ask for it, so we hand it over complete.
What about resource consent?
That is a separate set of rules. National standards now allow most detached minor dwellings without a resource consent, but some sites still need one. We check yours at the site check.
