作为其环境、经济和规划价值的一部分，该项目保留了原来的封套。一个实质性的较低的居住空间是敏感地插入到原来的织物下面，以利用在现场向后方的下降，延伸到现有的住宅下面，向外的花园改造它-而一个精心设计的后方底层以上包含了现有的节奏，前面的房间在新的更低的地面在下面。

The project retains its original envelope as part of its environmental, economic and planning values. A substantial lower ground living volume is sensitively inserted beneath the original fabric to harness the fall in the site towards the rear, extending deeply beneath the existing dwelling and outwards towards the garden to transform it - while a re- crafted rear ground floor above enfolds the existing rhythm of front rooms over the new lower ground below.

这两个级别都接受一个中等大小的轻量级加法，它外推现有的墙壁对齐度、排水沟水平和围壁高度-即立即扩展和颠覆现有的几何图形，以呈现依附在保留的后织物上的原始白话形式的解释镜像片。一个偏心屋顶形式外推原来的南部屋顶飞机，以减轻相邻的影响-提升到光明和树木的看法向东，同时也折叠向上，以进入北部的光线和天空通过一个唯一的防火窗口沿边界。

Both levels accept a modestly-sized lightweight addition which extrapolates existing wall alignments, gutter levels and enclosing wall heights - that at once, extends and subverts existing geometries to present an interpreted mirrored slice of the original vernacular form attached to the retained rear fabric. An eccentric roof form extrapolates the original southern roof plane to mitigate adjacent impacts - lifting to light and tree views to the east, while also folding upwards for access to northern light and sky through a sole fire-rated window along the boundary.

该项目的大部分都是在保留的砖石和屋顶封套内精心制作的。在最初的屋顶形式中雕刻的拱形天花板和天窗扩大了进入底层中部的光线和天空的体积-同时有意识地让出了楼面面积，允许在空间上扩展到较低的层次，并向上延伸到外部环境的视图，以加强与其设置的联系。

The majority of the project is carefully crafted within the retained masonry and hipped roof envelope. Vaulted ceilings and skylights carved within the original roof form expand volumes for access to light and sky within the middle of the ground floor - while consciously surrendered floor area permits a generous stair void that spatially expands to the lower level below, and upwards to views of the external environment to strengthen connections to its setting.

位于低地半地下后方深处的公用设施使起居空间能够直接连接到花园和夹克兰达树，而上面经过改造的底层增加了浴室、主卧室和适应性卧室，为将来的研究提供了灵活性。开窗安置改善了自然光通道，并促进被动通风，由吊扇和屋顶通风系统，以排气捕获的热量，从原来的屋顶空间。

Utilities located deep within the semi-subterranean rear of the lower ground enable direct connection of the living space to the garden and jacaranda tree, while the re-worked ground floor above adds a bathroom, main bedroom and adaptable bedroom providing flexibility for future use as a study. Fenestration placement improves natural light access and promotes passive ventilation, assisted by ceiling fans and a roof venting system to exhaust trapped heat out of the original roof space.
