海辺の別荘-野間の改構 / ナノメートルアーキテクチャー

Sand prevention and reconstruction to revive the way of living of our predecessors

“Why not?”
It is this beachfront villa renovation that makes you think so.
Mihama Town in Aichi Prefecture is located at the Chita Peninsula’s tip, and the site is the best location with the sea in front. There are no buildings next to each other. Because it was rewritten to the impossible construction area by the change of the regulations, it was inevitably not a rebuild but a renovation.

Strong sea breezes carry a lot of sand in addition to salt damage. Sand also enters from the gaps of the sash, and sand accumulates on the windowsill. A warehouse was built on the seaside to prevent sand from blowing into the garden, but sand blows in from the warehouse’s gap and the existing building. The measures were repeated on the spot, and the view of the sea was lost. The problem was also on the second floor. It is a mixture of Japanese-style and Western-style interior decorated by former residents, and it stands out before enjoying the sea.

The request was 4 points. To prevent sand more than ever, to get a view of the sea, to have a place where the garden and living room can be used together, to be a calm place on the second floor. There were no existing drawings, and when we went on the survey, we could see the same tiles as the exterior walls from the back of the living room wall on the first floor. In other words, it was expected that the living room was being used as an outdoor piloti. Originally, the sea view from the garden without the warehouse would have been wonderful, after going through the continuous piloties to the garden.

In this renovation, we thought it would be desirable to go ahead while recovering the original goodness and solving it.
We made a sand room, which was not an air room, which integrally surrounded the outer wall, window, and warehouse with a polycarbonate corrugated sheet. It is an environmental device that also serves as a cover to protect equipment on the outside wall from salt damage and serves as a double outer wall to reduce sand’s ingress. In addition, since the corrugated sheet is easy to replace, it is easy to maintain. The corrugated plate adopted frost type so that scratches and salt crystals in the sand were not noticeable.

As a result, the living room returned to the dirt floor to pass through to the garden and became a semi-indoor space. On the second floor, the excess material was reduced, and black lines were inserted to divide the space between Japanese and Western. Both were organized by pulling in the street.

Reading from the history of fighting with the former’s site, a situation appeared that “it should have been.” It is a work that was solved by evolving architecture and usability. (Atsumi Nonaka, Yuki Mitani)
