Hi All,

Thanks for visiting my blog.


Under the new Auckland Unitary Plan (AUP) the  maximum building coverage of private properties has became larger, if these sites are in Mixedhousing suburban, Mixedhousing urban or Terrace Housing and Apartment residential zone.



The building coverage refers to the building footprint in relation to a site area.

For example, if the Max. building coverage is 35% and the area of the site that the building sits on is 500m2, the building footprint will be able to be up to 175m2 (500m2 x 35%).

It normally means  that the larger the building coverage is, the larger the house you can build  your site.

Max. Building Coverage in Different Residential Zone

Single House: 35%

Mixedhousing suburban: 40%

Mixedhousing urban: 45%

Terrace Housing and Apartment: 50%

You can check which residential zone is for your property by following the link below:

Auckland Council GEOMAP 

The building coverage was in many cases only 35% before AUP came out so there has been a big change except for Single House zone.

If you planing to build a new home or do extension of the existing house you have a great opportunity now.


Please let us know if you have any enquiries.



新しいAuckland Unitary Planでは、もし該当する物件が、 Mixedhousing suburban, Mixedhousing urban or Terrace and Apartment のいずれかの住居ゾーンである場合は、Maximum Building Coverage (建蔽率)が大きく拡大されます。



Building Coverageとは、住宅の一階部分の広さが土地に対してどれだけの割合であるかを表すものです。
例えば、Maximum Building Coverageが35%の場合は、500m2の土地に住宅を建てる場合、一回の床面積は175m2(500m2 x 35%)となります。
Max. Building Coverageが大きければ大きいほど、より大きな建物を建てられる事になります。
(Building Coverageは厳密には一階床面積とは多少違いますが、ここでは説明を割愛します)

住居ゾーンによるMax. Building Coverageの違い

Single House: 35%

Mixedhousing suburban: 40%

Mixedhousing urban: 45%

Terrace Housing and Apartment: 50%

AUP施行前は、多くの場合Max. Building Coverageは35%でしたが、AUP後はSingle Houseゾーンを除いて、大きく変更されました。





新的奥克兰统一规划建筑设计下,你所有的房屋该当独栋别墅,中密度别墅,公寓三个里的一个的住居区域的话,建蔽率(Maximum Building Coverage)被大扩大了。
Building Coverage是房子的一楼的面积对土地的面积的比列。
批示Maximum Building Coverage是35%的情况,想建房屋对500m2的土地上的话,可以建175m2大的面积的房子(500m2×35%)
Max Building Coverage是越大越好,如果可以做越大的房子。

Maximum Building Coverage的不同批住房区域

独栋别墅: 35%
中密度别墅: 40%
中密度都市: 45%
公寓: 50%
奥克兰统一规划建筑设计实施之前大多数是35%的Maximum Building Coverage。

I love architecture and design so much that I have been to so many buildings and places around the world such as Sydney Opera House in Sydney, CCTV building in Beijing, Empire State Building in New York, Royal Palace in Bangkok, Houryu-Ji in Nara, etc. However, the residential building attracts me the most. For nearly 10 years I have visited heaps of local and historical homes around New Zealand which I feel the builders’ great workmanship as well as occupants’ life.

From this experience my aim is to design and provide the comfortable and affordable houses with the spirit of Japanese workmanship that people enjoy and improve their quality of life.

In this blog I write my everyday experience of work to show what is a designer’s work and how it goes at Japan Homes.

Any comments or questions are very welcome.
