当开始对加州郊区丹维尔的一栋几乎空无一人的70年代的办公楼进行改造时，西德尔-帕克拉万建筑事务所认为他们对主要的室内范围有一个清晰的认识。该项目要求对外部进行适度的升级，将一些最不吸引人的元素淡化或移除，并进行新的油漆和种植。相反，他们发现与一个具有前瞻性的建筑部门和一个富有冒险精神的客户的合作之旅，导致了一个大胆的设计，改变了建筑的价值和它所在的郊区角落。

When beginning the renovation of a nearly empty 1970’s office building in the California suburb of Danville, Sidell Pakravan Architects thought they had a clear understanding of a primarily interior scope. The program called for modest upgrades to the exterior, with some of the most unattractive elements toned down or removed, new paint, and plantings. Instead, they found a collaborative journey with a forward-thinking Building Department and an adventurous client, leading to a bold design that has transformed the building’s value and the suburban corner lot where it sits.

在第一次设计审查委员会会议上，建筑师们预计丹维尔会要求增加更多的元素，以符合该地区盛行的淘金热土建筑。令他们惊讶的是，委员会向建筑师和业主提出了挑战，要求他们以更现代的风格对建筑进行改造，以适应城市的环境，并使其脱颖而出。客户同意了。该建筑经历了全面的改造，为曾经平淡无奇、未被充分利用的建筑带来了新的身份。设计策略包括为现有的结构设计一个新的围护结构，并增加一个大胆的体积声明，对材料、历史和社区的规模保持敏感。新的建筑立即引起了城市的赞誉，新的租户名册也搬了进来。

During the first Design Review Board meeting, the Architects expected that Danville would require adding more elements to align with the gold rush vernacular architecture prevalent in the area. Much to their surprise, the board challenged the Architects and the owner to overhaul the building in a more contemporary style that would fit the city’s context and stand apart. The client was on board. The building underwent a total transformation, resulting in a new identity for what was once a bland, underutilized structure. The design strategy incorporated a new envelope for the existing structure and an addition of a bold volumetric statement that remains sensitive to the materials, history, and scale of the neighborhood. The new building immediately drew praise from the city, and a new roster of tenants moved in.

作为对建筑围护结构的物理层的研究，该设计策略为丹维尔的 “旧金山棒 “建筑历史增加了另一个层次。19世纪末的旧金山棒式建筑风格使用简单的木条来装饰以经典矩形窗台为主的外墙。虽然这种风格因其装饰性很容易被认可，但它最好被理解为当时的木材技术的结果。因为这种风格在简单的装饰策略中使用了一种广泛可用的材料，允许有很多变化，它反映了在一个快速增长的时代所碾磨的木材类型。带着对木材技术如何促进美学语言的兴趣，本设计使用了新的垂直木板和突出的窗体，以唤起丹维尔历史城区的建筑。

As a study in the physical layers of the building envelope, the design strategy adds another layer to Danville’s “San Francisco Stick” architectural history. San Francisco Stick style of the late 1800’s used simple wood strips to decorate facades dominated by the classic rectangular bay windows. Although the style is easily recognized for its decorative qualities, it is best understood as a result of the wood technology of the time. Because the style used a widely available material in a simple decorative strategy that allowed lots of variety, it reflects the type of wood milled during a time of rapid growth. With interest in how wood technology can foster an aesthetic language, this design uses new vertical wood boards and protruding window volumes to evoke the architecture of Danville’s historic downtown.

当代的木材加工厂和林业管理使我们可以获得一系列鼓舞人心的木材品种、规模和纹理。为旧金山棒子语言增加了一个新的层次，这个设计也将这些当代技术产品分层在经典的加州木结构上。这个建筑有一个简单的木质结构，被包裹在一个丰富、复杂、多层次的包装中。

Contemporary wood mills and forestry stewardship make available an inspiring range of wood species, scales, and textures. Adding a new layer to the San Francisco Stick language, this design also layers these contemporary technology products over classic California wood construction. This building has a simple wood structure enclosed in a rich, complex, multi-layered wrapper.

在结构上，现有的8000平方英尺的建筑和新增加的3000平方英尺的建筑都有一个两层的木质框架结构，在地面的混凝土板上。木结构是由传统的花旗松托梁和墙骨、Glulam梁以及由工程木材和钢制成的 “Red Built “开放式腹板桁架组成。建筑表皮的第一层是原始的T-111护墙板；它本身就是木材技术历史课上的一层。下一层是用可持续矿物密封剂完成的雪松雨幕。

For the structure, both the existing 8,000 square-foot building and the new 3,000 square-foot addition have a two-story wood-framed structure over a concrete slab on grade. The wood framing is a mix of conventional Douglas Fir joists and studs, Glulam beams, and “Red Built” open web trusses made of engineered wood and steel. The first layer of the building skin is the original T-111 siding; itself a layer in the history lesson of wood technology. The next layer is a cedar rain screen finished with a sustainable mineral sealant.

它包裹着现有的和新的建筑体量。在地面上，涂漆的红柏木箱引入了另一种纹理和规模，给建筑带来了新的重量，同时提供了急需的存储空间。从工地上一棵垂死的雪松树上回收的木材被用来制作护栏、门把手和楼梯踏步。同样地，主要的窗台也被重新诠释为现代的尺度，以回应日益扩大的郊区规模。完成的项目是各种医疗和牙科诊所的所在地，现在是社区的一个繁华的医疗中心。

It wraps the existing and the new building volume. At the ground level, painted cedar shake boxes introduce another texture and scale, giving the building a new heft while providing much-needed storage. Wood re-purposed from a dying deodar cedar tree on the site was used to make guardrails, door handles, and stair treads. Similarly, the dominant bay windows have been reinterpreted in a modern scale that responds to the increasingly suburban scale. The completed project is home to various medical and dental practices and is now a bustling healthcare hub for the community.
