“设计枢纽”
随着学生规模的不断扩大，内布拉斯加大学林肯分校建筑学院迎来了关键转折点：校方需扩展教学空间，但面临两个选择——要么拆除现有建筑，要么在原有的三座历史建筑构成的综合体基础上进行叠加式建设。“建筑大厅”（Architecture Hall）建于1891年，随后于1921年加入法学院大楼，1985年又新建“连廊楼”（Link Building）将两者连接在一起，增设了电梯、消防楼梯和中央大厅。尽管连廊楼的体量不小，却未能有效提升整体城市语境下的建筑群价值。
With a growing student body, the University of Nebraska-Lincoln College of Architecture reached a critical juncture: it needed to expand its facilities but faced a choice to either demolish existing structures or build upon its historic complex of three interconnected buildings. Architecture Hall, constructed in 1891, was followed by the Law College in 1921, and then in 1985, the “Link” Building was added to unify the complex –introducing elevators, fire stairs, and a central lobby. Despite its large footprint, the Link contributed little else to the urban ensemble.

此次新扩建项目正是策略性地利用了这段功能相对薄弱的连廊部分，在保留历史建筑整体完整性的前提下，新增了灵活的设计工作坊与评图空间，并对原有历史剧场进行了修复。同时，新增的主立面与入口标志着学院面向校园的新形象，成为建筑学院作为“设计枢纽”的象征。

The new addition strategically leverages this underutilized infrastructure to preserve the integrity of the historic complex, while introducing flexible studio and critique spaces and restoring its historic auditorium. It also redefines the College’s presence on campus with a new front façade and entrance —a symbol of the design hub.

在紧张的工期压力下，项目采用加速交付模式，虽无法正式申请 LEED 绿色建筑认证，但校方仍坚持实施关键的可持续策略。设计方案采用了预制化的大跨度木结构建造方式，使建筑本身成为对学生具有教育意义的示范性工具。建筑主体几乎完全由木材构成：梁柱采用胶合木（glulam），楼板为交叉层压木板（CLT）。这些构件在工厂预制，并在不到一个月内现场完成安装——每层楼仅用一周时间即可完成搭建。
An ambitious timeline necessitated an accelerated delivery model, with no means to adopt formal LEED certification. Despite this challenge, the University was committed to making a few critical decisions that would place the project on the sustainable spectrum. Our proposal embraced prefabricated mass timber construction, positioning the building itself as a pedagogical tool for its audience. The structure is composed almost entirely of wood, with beams and columns fabricated from glue-lam members and floor slabs from cross-laminated timber (CLT). Fabricated off-site and installed in under a month, each floor was erected in just one week.

这种高效与教学导向的理念也体现在内装选择上：通过有选择地暴露结构与材料，避免冗余施工工序，增强自然采光效果，同时将建筑构造本身转化为教学资源。北立面采用纤维增强复合材料面板（Kalwall），作为一体化外墙系统的单一安装来源，在控制关键视线开口的同时，引入漫反射和间接光线，为设计工作坊创造理想光环境。
This economy and didactic ethos extended into our finish choices, exposing raw materials opportunistically to eliminate redundant trades, enhance daylighting, and reveal the building’s organs as teaching elements. By adopting fiber-reinforced polymer panels (Kalwall) for the north façade, we utilized a single-source for the installation of an all-in-one exterior wall system, minimizing glazed openings for key views while maximizing diffuse and indirect light ideal for studio work.

项目基地位于林肯校区西侧边缘，建筑学院在三个关键空间关系中起到重要转化作用。首先，作为师生往返停车场与橄榄球场的必经之路，该建筑在比赛日亦成为校区的门户与活动节点。其次，作为校园北入口，建筑所在的林荫轴线直接联通校园东西向主轴与由Philip Johnson设计的谢尔顿艺术博物馆（Sheldon Museum of Art）。北立面设计为倾斜状开窗，视线正对这两个重要场所。再次，北立面也成为建筑学院的新主入口，将四栋建筑统一为一个整体。
Situated at the western edge of the UNL campus, the College of Architecture plays a transformative role in three key site relationships. First, as part of the weekly promenade between parking lots and the football stadium, the building acts as both a campus threshold and an outpost during gameday tailgating activities. Second, as a gateway into campus, the north allée links the east-west campus axis directly to the historic Sheldon Museum of Art, designed by Philip Johnson. The raked fenestration of the north façade intentionally orients framed views toward these two event destinations. Third, the north façade serves as the new main entrance for the College of Architecture, unifying the complex into a cohesive whole.

在这四座建筑交汇之处，设计引入一个户外庭院，作为中央开放式教学空间，为师生活动与交流提供了共享平台。
At the intersection of these four buildings, an outdoor courtyard anchors the center of this complex with an open-air teaching space.
