作为经济适用房，Waratah二手房是由简单的基本原则形成的；通过最大的效率来降低成本。使用高性能的预制材料，创造了简单的箱体形式，加快了施工时间，并保持低成本。
An exercise in affordable housing, Waratah Secondary house is shaped by simple underlying principles; minimise costs through maximum efficiency. The use of high performance, prefabricated materials create the simple, box form expediting construction times and keeping costs low.
由于防洪控制的原因，主要的生活层高出自然地面1.2米。硬质和软质景观包括楼梯、露台和土堆被引入。这些户外连接为居民提供了独特的区域，同时又是开放和独立的。
Due to flood mitigation controls, the primary living level is elevated 1.2m above natural ground. Hard and soft landscaping including stairs, decks and earth mounding are introduced. These outdoor connections provide inhabitants with distinct zones that are simultaneously open and separate.
我们的客户在每一个可用的机会都倡导灵活性。建成后，Secondary house是一个单间卧室的工作室住宅，在家工作或商业工作室空间。将开放的工作室分割成两个相等（床位）的房间，提供了额外的租赁选择。
Our client championed flexibility at every available opportunity. As built, Secondary house is a one bed studio dwelling, work from home or commercial studio space. Splitting the open studio into two equal (bed) rooms provides additional rental options.
为了提高效率，我们选择了简单、低维护的建筑形式，并将现场装饰保持在最低限度。建筑由砖石基础（抗洪），与预制的模块化组件组成，包括。结构保温墙体和屋顶板，预制纤维水泥板，金属网围栏板和模块化的细木工板，所有指定的手段，通过现场外预制，最大限度地减少现场浪费。
A simple, low maintenance building form was selected for efficiency with on-site finishing kept to a minimum. Construction consisted of a masonry base (flood resisting), with prefabricated, modular components, including: Structurally insulated wall and roof panels, pre-finished fibre cement sheet panels, metal mesh fencing panels and modular joinery all specified as a means of minimising on-site waste through off site prefabrication.
在预算有限的情况下，我们优先考虑的是实际经验而不是技术。我们优先考虑的不是通过集成建筑系统来节约能源，而是投资于建筑围护结构。我们选择结构保温板（SIPs）作为主要材料，因为它具有环境效益、优越的保温性能和安装速度。大开间提供了交替捕捉和清理热量的能力，通过双层玻璃，木质可操作门窗，促进交叉通风，为居民提供热舒适度，以减少供暖和制冷成本。
With budget limitations, we prioritised the physical experience over technology. Our priority was not on energy saving by means of integrated building systems; we invested in the structural building envelope. Structural Insulated Panels (SIPs) were selected as the primary material due to their environmental benefits, superior insulation and speed of installation. Big openings provide the ability to alternately capture and purge heat as required through double glazed, timber operable doors and windows, promoting cross ventilation and providing thermal comfort to the inhabitants to reduce heating and cooling costs.
二手住宅不仅仅是一套老式公寓，它通过空间高效的规划增加了郊区的密度，减少了建筑占地面积，最大限度地利用了可用的室外空间。
More than a granny flat, Secondary house increases suburban density through spatially efficient planning reducing the building footprint to maximise the available outdoor space.
