東国三社の一角・息栖神社の参道沿い、船溜まりに湧く忍潮井に面して建つ地域交流拠点施設。江戸期に茶屋町として賑わい、昭和初期まで文人墨客が宿泊した柏屋旅館があったこの地の記憶を継承し、参道と水辺、歴史と現代をつなぐ場として計画された。
This community exchange facility stands along the approach to Ikisu Shrine — one of the three great shrines of the Togoku Sanja — facing the Oshioi spring that rises at the edge of an ancient boat basin. The site was once home to the Kashiwaya Inn, a celebrated Edo-period teahouse where literary figures came to stay. The facility inherits that layered history, conceived as a node connecting the shrine approach with the waterfront, and the past with the present. The generous second-floor cantilever is achieved through a reciprocal timber structure inspired by segai-zukuri. Stone-paved flooring drawn in from the approach creates an inner pathway; entrances on three sides welcome visitors from every direction. Closed to the street yet open to the community.
息栖市内に残る国指定重要文化財・山本家住宅に見られる伝統的な木造片持ち構法「せがい造り」に着想を得て、茨城県産一般製材の短材を井桁状に4段組み合わせたレシプロカル構造によって、大断面材を用いることなく大きな跳ね出しを実現した。
Inspired by segai-zukuri, a traditional timber cantilever technique seen in the nationally designated Important Cultural Property Yamamoto Residence within the city, a reciprocal structure — combining short lengths of standard-cut Ibaraki timber in four stacked, grid-like layers — achieves a generous overhang without large-section members.
東国三社の一角を担う息栖神社の参道沿い、常陸利根川から引き込まれた船溜まりの一角に湧く忍潮井（おしおい）に面して、この地域交流拠点施設は建つ。整備前の参道には店舗がなく、参拝を終えた人々はそのまま帰路についていた。本計画は、参拝者の滞在する場所を提供するとともに、神栖市の情報を発信する拠点として計画された。
This community exchange facility stands along the approach to Ikisu Shrine — one of the three great shrines of the Togoku Sanja — facing the Oshioi spring, a sacred well that rises at the edge of a boat basin fed from the Hitachi-Tone River. Before the facility was built, the approach offered no places to stop, and visitors would simply turn home after paying their respects. The project was conceived to provide a place where pilgrims could linger, while also serving as an information hub for Kamisu City.
住宅地に囲まれた敷地では、周辺住民へのプライバシーへの配慮から、参道側への大きな開口という選択を難しくした。その制約を逆手にとり、2階床を支えるレシプロカル構造を建物の内外に連続させ、参道の石畳風の床仕上げを基壇や室内に引き込み、室内では参道からつながる「裏参道」として施設を貫いている。施設の3方向に出入口を設け、参拝者も地域住民もどこからでも入り込める構えとしながら、参拝者や地域住民が自然に立ち寄れる開放性を確保し、閉じながらも地域に開かれた構成となる。
外観は、息栖神社に見られる茶・朱・鳥居の鼠色・銅板屋根・石畳風仕上げなど、神社の色彩と素材を纏う。強いランドマーク性よりも地域の日常に静かに溶け込むことを優先したこの建物は、歴史や風景、人々の営みを緩やかに接続し、そこに集う人々の活動そのものを主役にする器として機能している。
Surrounded by a residential neighborhood, the site made a large opening toward the shrine approach difficult, out of consideration for the privacy of nearby residents. Turning that constraint to advantage, the reciprocal structure supporting the second floor runs continuously between interior and exterior, drawing the approach's stone-paved finish into the podium and interior to form an inner approach that threads through the building. Entrances are set on three sides, allowing both worshippers and local residents to enter from any direction — securing an openness that invites people to stop by naturally, in a composition that is closed to the street yet open to the community.
The exterior draws from the colors and materials of Ikisu Shrine — earthy browns, vermilion, the grey of the torii, copper roofing, and stone-paved finishes. Prioritizing quiet integration over bold landmark status, the building gently connects history, landscape, and the lives of those who pass through it.
水辺へと張り出すテラスからは、船溜まりと常陸利根川の水景、そこに沈む夕日が一望できる。
From the terrace that reaches out over the water, visitors watch the evening sun sink into the Hitachi-Tone River below.
