Residential building fabric is all too often razed in order to create new residential structures that maximize the zoning envelope, to the detriment of the neighborhood fabric and scale. By contrast the design approach for this project integrates analysis of typical characteristics of construction vis-a-vis the era of construction, building-site relationships, and sustainable strategies in order to join competing interests, save the building and preserve its role in the community.

住宅建筑结构经常被夷为平地，以创造新的住宅结构，最大限度地扩大分区范围，从而损害邻里结构和规模。通过对比，本项目的设计方法综合分析了建筑与建筑时代的典型特征，建筑与场地的关系，以及可持续发展的策略，以加入相互竞争的利益，拯救建筑并保持其在社区中的作用。

This house, built in the 1960s, faces south on a wooded lot in Bethesda, Maryland. The Bethesda house had limited and lifeless connections to its site, and a dearth of habitable spaces that adjoined the landscape.

这座房子建于20世纪60年代，位于马里兰州贝塞斯达的一片林地上，朝南。贝塞斯达的房子与它的地点有着有限的、没有生命的联系，而且周围的景观也缺少可居住的空间。

With excessive energy consumption, poor construction characteristic of its era compounded by considerable deterioration as the baseline condition in which we found the home, the house then suffered a major blow–burst pipes rendered the house uninhabitable. This last event prompted the owners to either raze or resuscitate their home.

由于能源消耗过多，建筑质量差，加上我们找到房子的基线条件严重恶化，这所房子随后遭受了严重的爆管，使房屋无法居住。最后一次事件促使房主们要么把房子夷为平地，要么让他们重新振作起来。

We implemented passive approaches for daylight and ventilation, a new vapor-managed building envelope, a state-of-the art insulation strategy, and updated high-efficiency mechanical systems.

我们实施了日光和通风的被动方法，一种新的蒸汽管理建筑围护结构，一种最先进的绝缘策略，并更新了高效率的机械系统。

We stewarded the development of a masterplan that manages stormwater, creates habitat for indigenous species, and selectively embraces trees thereby preserving the quality of the community. Our strategy saved the existing building, preserve the site and the existing trees contributed to the preservation of the neighborhood history.

我们制定了一项总体计划，管理雨水，为土著物种创造栖息地，并有选择地拥抱树木，从而保护社区的质量。我们的策略拯救了现有的建筑，保护了遗址，现有的树木也为保护邻里历史做出了贡献。

The renovated home includes 25% increased fenestration with glazing type and area tuned towards exposure, and a new building envelope achieving a 35% improvement over the new International Green Construction Code code baseline.

翻新后的住宅包括25%的窗洞，玻璃类型和面积调整为暴露，新的建筑围护结构比新的国际绿色建筑规范基线提高了35%。

Bringing in daylight and natural cross ventilation, the new design maximizes the benefits of available sun in winter and abundant shade in summer provided by the wooded context while retaining the tie between house and site that inspired the original design.

新设计引入了日光和自然交叉通风，最大限度地利用了冬季可用的阳光和茂密的夏季阴凉处的好处，同时保持了住宅与场地之间的联系，启发了最初的设计。
