John F Kennedy Center for the Performing Arts, Steven Holl, under construction: Holl was tasked with adding 10,000 sq m to the already sprawling centre. Not known for his subtlety, the architect has managed to design a handful of low-slung white appendages that enhance the existing structure without stealing the show. They flank a grassy landscape of gingko trees, pools and performances spaces

每一次总统选举都会使华盛顿进入人口流动。然而，除了政治之外，这个城市也欢迎年轻的家庭和毕业生，因为他们逐渐把自己重新定位为一个伟大的全才。随着惊人的绅士化和一场美利坚合众国革命，将华盛顿人引入纽约式生活，你会认为城市的织物会自圆其说。

然而，要在这里建造这些东西是非常困难的。繁文缛节是生活中的一个事实，保守派的老一辈人也是如此。花了一项新的棒球专营权，启动了摇摇欲坠的海军造船厂的重建工作。大卫·阿贾耶(David Adjaye)著名的非洲裔美国人历史文化博物馆(National Museum Of Africa American History And Culturation)于去年开业，这座博物馆

在一个以政府办公空间为特征的官僚主义城市，当地设计师/开发商布鲁克·罗斯(Brook Rose)看到了一个罕见的地标仓库的潜力，这个仓库曾用于制造一些第一批旋转式陀螺仪发动机。与此同时，纽约建筑师史蒂文·霍尔(StevenHoll)的奥巴马时代的基础设施项目将在较短的时间内开放，对艺术也同样如此。位于底特律国家购物中心(NationalMall)以南两个街区的SmithGroupJJR将一个具有里程碑意义的运输仓库改造成了博物馆，在辉煌上与史密森人匹敌。

上升的东西往往会被镜面玻璃淹没。但也有例外。虽然规划者们为罗杰斯合伙公司和PWP重新设计宪法花园提供了绿色照明，同时REX建筑公司还设计了一座精致的玻璃办公大楼，但也有一些示范性的项目取得了成果。

Museum of the Bible, SmithGroupJJR, opening November 2017:  Conceived to house some 40,000 biblical artefacts, one for each square metre of space, the non-sectarian Museum of the Bible launches later this year, opening at the original train portal, decorated, fittingly, in stained glass displaying a portion of the Great Isaiah Scroll

Museum of the Bible, SmithGroupJJR, opening November 2017: Jerusalem-stone columns punctuate the 12m-high flatiron, where much of the collection of scriptures, stones and antiquities sit beneath a backlit mock-fresco ceiling. Further up a floating stairwell, a two-storey rooftop addition blanketed in a glass curtain wall houses a theatre and ballroom with views over the Capitol

Rosedale Residence, Kube Architecture, 2017:  Let the Obamas have Kalorama, with all its media scrutiny and hopped-up security. Two miles northwest, on the last available plot of a 280-year-old heritage area, Kube Architecture has built a 600 sq m house bordering three acres of parkland and literal white-picket fences

Rosedale Residence, Kube Architecture, 2017: Named for the Rosedale Conservancy, the family home is made of two offset saltbox structures, modern barns that nod to the neighbourhood’s rural history. It’s just 15 minutes to Georgetown or the National Mall, but the clean, wide-windowed build, stepping down to rolling lawns, is miles outside town in spirit – and as self-contained as can be, with an outdoor pool and two-storey indoor basketball court

National Gallery of Art extension, Hartman-Cox, 2016: Last year the East Building of the National Gallery of Art, an annex originally designed by IM Pei, added an impressive 1,200 sq m of exhibition space to an already cavernous plan, with two new galleries and a sculpture terrace, inaugurated with a highly distinctive electric-blue ‘cock’ sculpture by Katharina Fritsch

National Gallery of Art extension, Hartman-Cox, 2016: The expanded spaces, designed by local architects Hartman-Cox, will allow for the exhibition of larger sculptures and installations, like Calder mobiles and epic Rothko canvases

The Helicopter Factory, Brook Rose and Mike Burton, under construction: Developer Rose partnered with Baltimore architect Burton of Urban Design Group to split the weathered-brick space into two large flats and repurposed a newer annex into 13 townhouses, landscaping a courtyard between the two types

Woodridge Library, Bing Thom Architects, 2016: This public library located in fast-gentrifying Woodridge, a residential neighbourhood in northeastern DC, is business in the front, fun in the back. A contemporary yet subtle street presence in grey precast concrete belies an interior flooded with light from the lattice-topped indoor-outdoor penthouse

Woodridge Library, Bing Thom Architects, 2016: An oculus in the third floor directs it downward into the atrium, accessed by wide stairs and swooping balustrades. The stacks stick to the perimeter and wide, round bookcases echoing the oculus, leaving most of the floor to circulation. Double-height glazing on the back wall faces a deep terrace and the open green of Langdon Park

Rock Creek, NADAAA, 2015: NADAAA from New York and Boston, effectively doubled the volume of this 1920s brick house and added as much glazing as the structure would allow. All that remains now is a narrow, classical façade in the vernacular red brick and the grandeur, familiar to this forested neighbourhood north of the city

Rock Creek, NADAAA, 2015: The interior was recast in light laminated plywood panelling, flooring and built-ins. It rises to a vast skylit play loft that carries natural light down through the home – not that any more is needed for all the deep, wide window bays and multi-level voids connecting the common rooms

Rock Creek, NADAAA, 2015: At its heart, a zig-zaggedy spiral staircase with jagged wood balustrades like teeth. Creatively carved wood peek-a-boos between rooms add interest
