Last October, I was given a tour of the Oya stone quarry in Tochigi Prefecture. In order to cut out the desired stone from the Oya stone bedrock, the transport routes and construction flow lines are literally carved into the Oya stone. Rather than assembling small parts, he creates space by sculpting the earth. I was overwhelmed by the spatial beauty of the stone quarry, carving a staircase in the depth direction into the vertical bedrock. Thank you Mr. Kaminaga for this valuable experience.
大谷石の露天掘り現場。地球を彫刻して石を切り出す。
Oya stone open pit mining site. Carve the earth and cut out the stone.
Thank you to Konno Construction and I-Chief Builder for the beautiful staircase. There were no dowel holes in the tiers, and the force girders were joined perfectly in a curved shape, and to top it all off, all of the processing was done on site rather than in a processing facility...I'm really grateful.
WAXで拭き上げるとたいへん美しい木目が現れます。
When wiped with WAX, a very beautiful wood grain appears.
脚の甲が当たった時に柔らかいように太鼓面を取りました。
I made the drum surface so that it would be soft when it hits the top of the leg.
力桁を半分掛けたところです。
This is where the power digit is multiplied by half.
力桁をピッタリと頑丈に継いでいます。
The force girder is connected perfectly and firmly.
The photo shows the stair treads and wall paneling. The thickness of each wall paneling is not uniform. But why does it fit perfectly with the tiered board without any gaps? He casually puts on a cool face as the master carpenter, but...
The contrast between the lively red Japanese pine and the cool wood-wool cement version worked well, but I connected the air supply and exhaust pipes from the ceiling-suspended range hood on the left side of the photo to the opening in the wall on the right side. Of course, the height has been carefully calculated so that it goes under the central beam and does not touch the top of the hanging cabinet on the right.
Additionally, thin-walled steel pipes (spiral ducts) are used for both the supply and exhaust pipes, so if you don't wrap the pipes tightly with insulating material, you will end up with severe condensation after you move in.
This is Kita 7-jo House, where yesterday's heavy snow has cleared up as if it were a lie. Including the tower, it is as tall as a four-story wooden building.
The exterior material is larch wood. These materials are from Tokachi, the hometown of Konno Construction Co., Ltd., which is in charge of the site. Most buildings these days have exteriors made of materials other than wood. I myself have used various materials such as sheet metal, plastering, siding, etc., but before I knew it, wooden exterior walls became the most popular choice.
It's not that I don't like other materials; it's mainly thanks to the deepening awareness of homeowners and local efforts that have made it easier to use wood, but materials that are appropriate for the environmental era have gained civil rights. As an author, I am very happy about this.
Unfortunately... there is still a strong negative image that wood burns and rots, but that is not necessarily the case. Nowadays, additional insulation improves fire resistance, and as a result, the wood exterior has even been certified by the minister as a fire-retardant structure. The research is conducted by Hokusouken (Northern Building Research Institute) in Asahikawa.
For that reason, although it looks like a wooden exterior at first glance, it is actually fireproof. The exterior design allows for safe use even in built-in urban areas.
昨日の大雪で屋根の上には１ｍ以上も雪が積もっています。
Due to yesterday's heavy snowfall, more than 1 meter of snow has piled up on the roof.
From the snowy eaves, you can see that the prevailing winter wind blows gently from the back of the screen to the front. By installing a passive ventilation exhaust port on this side (downwind side), you can easily obtain exhaust power from natural energy.
床ガラリの見本です。今回は床材がナラ材なので枠材は共材としてスッキリ納めようと思います。
This is a sample of the floor louver. This time, the flooring material is oak wood, so I'm going to use the frame material as a common material to fit it neatly.
こんな感じに自然に床と枠が同化します。
In this way, the floor and frame will naturally blend together.
室内はどんどんボードが張られて行きます。
Inside the room, more and more boards are being put up.
