ランドスケープは、パーク全体が連動して、多様なアクティビティを受け入れる「うつわ」のような場所となるように、「すりばちシアター」や「おおはらっぱ」とパークセンターの関係性、周辺環境への開き方を考慮し、建築とランドスケープを一体的にゾーニングしている。パークセンターのデッキテラスを、敷地北西にある大阪臨海線や阪神高速道路の方向へ開くことで、音楽の大きな音が高速道路等の交通によるホワイトノイズによって緩和される構成とし、敷地周辺の住宅地の方への騒音・視線の配慮として、「実りの森」や「シーパス山」の起伏を設けた。「すりばちシアター」の芝生面の傾斜は、イベント時にはフェスのように芝生に座りながら、デッキテラスで演奏されている音楽が聴ける場所となるだけでなく、パークセンターのデッキテラスの屋根が、「すりばちシアター」に対しての音響反射板となるように角度をつける等、建築とランドスケープが連動して多様なアクティビティを受け入れるデザインを徹底した。敷地は地下水位が高く、平坦な既存地形に対して、高木を植える際には盛土を行う必要があることから、各々の「うつわ」の使われ方に応じたアンジュレーション(地形の起伏)を加え、イタリア、シエナ市のカンポ広場のような、普段使いの居心地のよい場所になっている。アンジュレーションの起伏の高さを、パーク内を歩いている方々の目線からは少し隠れる最大1.2m程度とし、曲線のベンチを設けることで、柔らかな「うつわ」の縁が形成され、各々の場所性を高める効果を持たせている。
パークセンターは、かたちとしても、アクティビティの受け皿としても、公園のランドスケープと一体的にデザインしている。活動を支える多目的ルームやワークショップスペースから半屋外広場、そして屋外の「すりばちシアター」へと、パークセンターから屋外へ連続的に空間がつながる構成とし、使い方によって利用者が自ら環境をチューニングできる仕組みを設けた。多目的ルームは、利用者やプログラムにより、折戸を開くことで「すりばちシアター」と一体で利用可能とし、同時に室内の可動間仕切りによって、ルームの広さを変えることも出来る。またワークショップでの意見をもとに、公園内の多様な活動を支える備品置き場や、緑地管理の方の休憩所として使用する倉庫の面積や数を決定した。またシーパスパークには、さくらエントランス、パークエントランス、ガーデンエントランスの三方向から出入りできることから、パークセンターには、ランドスケープやアンジュレーションの柔らかな雰囲気と呼応する曲線の大屋根を設け、裏側を設けない設計とした。 ファームハウスは、倉庫と半屋外スペースの組み合わせで出来ている。倉庫はファームハウス前に広がる市民農園「めーでるガーデン」の農具倉庫として機能し、半屋外のスペースは、市民農園の利用者が集まって交流できる。ワークショップに参加されていた車いす利用者の方の意見を反映し、車いす利用者も農作業ができるレイズドベッドのある大屋根の半屋外空間を備えている。半屋外のスペースを、園路を歩く公園利用者側に開くデザインとした。ここで育てた野菜は、倉庫横の流しで土を落として、パークセンターのワークショップスペースで調理して、皆と食べることが出来る。
A landscape that serves as a conduit between users and their surroundings, functioning as a receptacle for diverse activities – The zoning of the landscape is designed with a focus on the relationship between the Lawn Square and the Park Center, as well as how the park center interacts with its surrounding environment, emphasizing the manner in which it opens up. The design takes into consideration the potential for events like music festivals on the terrace of the Park Center. By orienting the terrace towards the northwest, facing the Osaka Rinkai Line and the Hanshin Expressway, any loud sounds produced during events are mitigated by the white noise from the traffic on the expressway. The roof of the Park Center's terrace is designed with consideration for its role as a sound reflector. By integrating architecture and landscaping, the sloping lawn of "Theater Lawn" becomes a cozy spot akin to Siena's Campo square on a daily basis, and during events, it transforms into a place where one can enjoy music while picnicking. By creating undulations such as those found in "Berry Forest" and "Sheepath Mountain," we are considering noise, sightlines, and pathways concerning the residential areas around the southwestern perimeter of the site. This undulation creates spaces for people to engage under the shade of the tall trees planted there, acting as vessels to contain activities. Simultaneously, by limiting the height variation to a maximum of about 1.2 meters, activities within these "vessels" are partially obscured from the pedestrian's line of sight, enhancing the sense of place inherent in these "vessels." We are also utilizing existing well water for activities in such as ‘Woolly Stream’ and ‘Play Ring.’ In the summer, we create new activities by turning them into children's water play areas. The Park Center, integrated with the landscape and open to both indoor and outdoor environments – The park center is designed to be integrated with the landscape of the park, both in its form and as a receptacle for activities. From the "multipurpose room" and "workshop space" to the terrace serving as a semi-outdoor plaza, and further to the outdoor "Theater Lawn", the park center is designed with a configuration that seamlessly connects indoor spaces to outdoor areas. This design allows for various possibilities depending on the users' needs, enabling them to tune the environment according to their preferences. The Multipurpose Room, with its movable partitions, not only adjusts the scale of the space but also manages the relationship between indoor and outdoor areas, making it available for integrated use with the park depending on the users and programs. Furthermore, based on workshops and feedback sessions, the area size and number of warehouses to be used as equipment storage areas to support various activities in the park, as well as the rest area for green space management personnel, were determined. Since the park can be accessed from three directions - Sakura Entrance, Park Entrance, and Garden Entrance, Park Center has front-facing features from all angles, eliminating any designated rear side in its design. The curved roof, echoing the curves and undulations of the landscape, is inclined to be higher on the side facing the Theatre Lawn, under which the main volume and the toilet + warehouse volume are separately placed. Farm House for the local community – The Farm House is comprised of the combination of the warehouse and semi-outdoor space. The warehouse functions as the tool storage for the Medele Community Garden, while the semi-outdoor space not only provides the gathering area for users of the Medele Community Garden but also includes the large roofed semi-outdoor space with Raised Beds where wheelchair users can engage in farming activities. This aspect also reflects the opinions of wheelchair users who participated in the workshop. The semi-outdoor space is designed to open up to park users walking along the garden paths. Vegetables grown here can be washed off the soil at the sink next to the warehouse, cooked in the "Workshop Space" of the Park Center, and can be enjoyed together with everyone. Play Park Roof serving as both the gate to the Play Ring and resting place The Play Ring near the Park Center is enclosed by bench walls, providing a space for enjoying muddy play. The Play Park Roof located at the entrance of this space not only provides the shaded resting area for parents while watching their children play but also serves as the gate to the Play Ring. Children who get muddy can use the outdoor showers at the foot-washing area of the Park Center, showing how the entire park is interconnected to support community activities.
