建主は都心に住む60代の夫婦。
子供たちの独立と自身のセミリタイアを機に、温泉と食が楽しめる暖かい場所で暮らそうと、大分県別府市への移住を決めた。それぞれが自分のライフスタイルをもつ2人と、元気な犬たちが暮らす住宅の計画である。「愛犬との自由な生活」と「自然を感じられること」。それが建主からの要望であった。
別府は南北方向の海岸と西方に連なる鶴見岳を中心とした山々、それらをつなぐ扇状地に別府八湯の温泉が広く分布しており、扇状地であるがゆえに坂の街とも呼ばれている。
計画地は、南側に境川の桜が立ち並ぶ砂防公園が臨め、東側は高崎山から別府湾まで一望できる環境豊かな敷地である。また、扇状地がもたらす急な坂道により、この敷地に取り付く南側道路の端から西側道路の端までは1.5mの高低差があった。
交通量の少ない周辺道路と整備された親水公園の散策路は、地域の人々が日常的に利用する場としても親しまれている。その特徴的な地形に寄り添い、家族や犬、周囲とのコミュニケーションを促すような建築を目指した。
南側の豊かな環境と連続するように、ドッグランを兼ねた大きな庭を設け、1階建物ボリュームを敷地北側に配置。塀は圧迫感がなく抜けのある軽やかな形状とし、2階のボリュームは建物の東側に寄せることで、通りに対して余白を提供するとともにのびやかな平屋のような建築とした。
外部のどの場所からもアプローチしやすいように断面を設定し、2カ所の玄関と犬用出入り口、そして散歩道が拡張していくように道路隅切りにも出入り口を設けた。
内部にはリビングダイニングの2つのカウンター、個室やラウンジ、ゲストルームを。外部には開かれた各階のテラスや庭、菜園など、将来を見据え内外にさまざまな居場所をつくった。
地形がもたらす高低差に建物が寄り添うことで、ソトとウチとの多様な関係が生まれたような気がする。
この建築が、そこに身を置く人に新たな発見や生活の豊かさをもたらすとともに、この自然豊かな坂の街との穏やかな繋がりをもつきっかけになればと思っている。（田中悠希＋榎本亮祐）
A house for living with a dog that blends in with its surroundings by taking advantage of the difference in elevation
The client is a married couple in their 60s who lives in the city center.
They decided to move to Beppu City in Oita Prefecture after semi-retiring, and their children also moved out of the house. They desired to live in a location with a warm climate where they could enjoy hot springs and good food.
This is a housing plan for two people who have their individual lifestyles where they live with happy, healthy dogs.
The client had requested the following things: “A lifestyle of freedom with the beloved dogs” and “be able to feel nature.”
Beppu has mountains centering on Mt. Tsurumi that continues to the coast in the northern and southern direction and widely distributed hot springs of Beppu Hatto in the alluvial fan that connects to it. It is called a town of hills because it is an alluvial fan.
The planned site is a land abundant in nature, where you can see the sand control park, where River Sakai’s cherry blossoms line up towards the south, with a complete view from Mt. Takasaki to Beppu Bay in the east. The steep hilly road the alluvial fan creates also creates an elevation difference of 1.5m from the edge of the southern road to the edge of the western road on the site.
The surrounding road with less traffic and the organized walking path of the water park is loved as a place the locals use daily.
We aspired for an architecture that would honor the characteristic topography and promote communication between family members, dogs, and the surrounding people.
As to continue with the environment abundant in nature in the south, a large garden with a place dogs could run around was created, and a 1st-floor building volume was installed in the north of the site. The fence has a light shape without a sense of pressure. The 2nd-floor volume is an architecture that looks as though it is a spacious one-story Japanese building by building it towards the east, creating space towards the street.
A cross-section is set, so it is easy to approach from any location outside. Two entrances, an entrance for the dogs and an entrance, are also created at the corner cut of the road as if the walking path is expanding.
The two countertops of the living-dining space, private room, lounge, and a guest room is in the inside the building. Various places of belonging, such as the open-air terrace on each floor and a garden, were also created, planning for the future.
It is as though the building created a diverse relationship between the outside and inside and is close to the elevation difference the topography created.
It is my wish that this architecture will bring new discoveries and abundant life for people who live there and be an opportunity for them to connect with the hilly town abundant in nature. (Yuuki Tanaka + Ryosuke Enomoto)
