Xylem（木质部）是Francis Kéré为Tippet Rise艺术中心设计的一座展亭，也是牧场草原游客安静的聚集庇护所。Xylem以树木重要的内部生命结构层命名，是一个游客们可以聚集在一起交流、欣赏Grove溪流沿岸白杨与棉白杨树林景色或者独坐思考的地方。
Xylem, the gathering pavilion for the Tippet Rise Art Center, has been designed by Francis Kéré as a quiet, protective shelter for the visitors of the ranch. Named to evoke the vital internal layers of a tree’s living structure, Xylem is a place where visitors may gather to converse, contemplate the views of the aspen and cottonwood trees near the bank of Grove Creek, or sit and meditate in solitude.

Located in a slightly sunken landform between the main facilities of the Art Center and the beginning of the hiking tracks, the pavilion rises in a clearing surrounded by aspen trees, facing a small creek. Entirely carved in wooden logs, the pavilion symbolically invites the visitor, who in the Tippet Rise Art Center is confronted with nature at its widest scale, to access the most secret part of nature, the heart of the trees. The sustainable pine wood used for the entire pavilion, locally sourced from a natural pruning process that saves forests from parasitic bugs, is employed in its raw appearance.

The logs of the canopy are assembled in circular bundles bore by a modular hexagonal structure in weathering steel, lying on top of seven steel columns. The upper surface of the canopy is carved sinuously in order to create a rounded topography that blends in the surrounding hills. At the same time massive and light, the roof is inspired by the “toguna”, the traditional most sacred space in every Dogon village, a wooden and straw shelter designed in order to protect from the sun but at the same time to allow the ventilation of the shaded space underneath.

展亭中，光束穿过垂直的原木形成独特的光影游戏，柔和地照射着下部有机形态的木质座椅和圆形抛光混凝土平台。座位元素的空间复杂性通过策略性的布置，凸显周边景观迷人的景色，鼓励游客根据自己的意愿就坐在不同的位置。通过探索，游客能够发现展亭不同的空间布局。在这里，游客可以一群人聚集在一起或与朋友交谈，与伴侣一同躺下来欣赏浪漫的景致或者独坐冥想。Xylem欢迎着游客和Tippet Rise艺术中心附近的整个社区，在Montana与Burkina Faso之间建立了独特的联系。它与Francis Kéré在Burkina Faso家乡村庄中的Naaba Belem Goumma中学同时建造，这所学校是Francis Kéré对其父亲的致敬之作，将面向Burkinabè草原整个区域的孩子开放。
In the pavilion, sunbeams penetrate between the vertical logs, creating a play of light and shadow that softly hits the underlying organically shaped seating, equally carved in wood. and the polished concrete circular platform. The spatial complexity of the seating elements emphasizes the stunning views of the surrounding landscape through strategic positions and encourages different appropriations by the visitor, who is invited to inhabit them at his wish. Through exploration, the user can in fact discover the different spatial configurations of the pavilion, gather in small groups or have a chat between friends, lie and watch the romantic views with his partner, or sit and meditate in solitude on his visit of the Art Center. Xylem welcomes visitors and the whole community that revolves around the Tippet Rise Art Center to a unique linkage between Montana and Burkina Faso as it is built in parallel with the Naaba Belem Goumma Secondary School in Gando, Francis Kéré’s home village in Burkina Faso, dedicated to Francis Kéré’s father, which will be open to the children of the entire neighboring area in the Burkinabè savannah.
