什么是granny flat？

注：可以简单理解为国内的东厢房，西厢房~

Designed for one or two persons, a granny flat is a self-contained living area usually located on the grounds of a single-family home. … In the building industry, the granny flat is most often known as an accessory apartment or accessory dwelling unit (ADU).

老奶奶公寓是一种独立的居住区域，通常位于独户住宅的地面上，适合一到两个人居住。在建筑行业，“奶奶公寓”通常被称为附属公寓或附属住宅单元(ADU)。

Building a granny flat is increasingly popular across Australia, but it’s not straightforward, due to differing rules.

在澳大利亚各地，建造老奶奶公寓越来越受欢迎，但由于规则不同，建造过程并不简单。

They can be custom-built, pre-fabricated, transportable, or even flat-pack.

它们可以是定制的，预制的，可运输的，甚至是扁平包装的。

建个granny flat有什么好处？

For home owners with the space, building a granny flat in the backyard can be a shrewd investment – delivering rental income and boosting a property’s value.

对于有足够空间的业主来说，在后院建一套祖母公寓可能是一项精明的投资——既能带来租金收入，又能提升房产价值。

With a two-bedroom granny flat in some parts of Sydney yielding up to $720 per week in rental income, the appeal of adding one is self-evident. 

在悉尼部分地区，一套两居室的祖母式公寓每周的租金收入高达720澳币，因此增加一套的吸引力不言而喻。

注：一年52个周，一周720，一年租金3.7万澳币……四年回本

A custom-built, two-bed flat with a kitchenette and bathroom costs about $130,000 to build, all up – although the exact amount depends on finishes.

一套带有小厨房和浴室的定制两居室公寓的建造成本约为13万美元（应为澳元，余同），全部加起来——不过具体金额取决于装修情况。
