Staging - Japanese Joinery Timber Frame Construction - House No. 1 - Part 3 in Hayama, Japan

Japanese House No. 1 - Timber Frame Construction Series - "Tatemae" - January 2021
In this series, we are in Hayama, Japan where we are participating in a new Japanese house build. The house design is a mix of traditional Japanese carpentry set on top of a modern concrete slab. This was done as per the request of the client and architect who decided on this style. The house is situated on a hillside overlooking picturesque Hayama.
House Information:
Land Area: ~310 sq. meters (~94 tsubo) (~3337 sq. feet)
Building Area: ~120 sq. meters (~36 tsubo) (~1292 sq. feet)
Total Living Area: ~102 sq. meters (~31 tsubo) (~1098 sq. feet)
The house has a living room/dining/kitchen open plan, 2 bedrooms with additional guest room, toilet room with vanity, washer/dressing room, Japanese split shower with bathtub, and an attached wooden deck.
In Part 3 of the House No. 1 build, we are staging the rest of the wood for the Tatemae (建前) that will happen very soon. There is always a big build up at the work site on the days leading up to the Tatemae. Tensions are pretty high and the stress levels can be elevated. There is a lot of pressure on the carpenters to make sure everything is correct and all the pieces are there. A missing piece or an incorrectly cut part can cause a big slow down in the process. We learn a little about chemical anchors and how the deck posts will be installed in this house. The posts for the decking will not be fastened down to the stones, instead they will be set over threaded rods which will be enough to prevent any side to side shift.
This episode does not show much technical information, however, we have a chat with the CEO and Founder of Fujimoto Traditional Carpentry, Ryo Fujimoto. He tells us about where, what, and why he builds traditional homes vs. the modernized "scrap and build" style construction predominately found throughout Japan. We would have to agree that garbage in Japan is a big problem. With industrialization and modernization happening for the last 70 years, there has been a lot of throw away products that end up collecting on this tiny island nation. This is not only a problem in Japan, but in other places of the world which are going through the same cycle of industrialization and modernization. It is interesting to listen to the carpenter's stories and why they decided to do this type of work and construction. Most Japanese carpenters share the same feelings about building a quality product that will last a long time and be healthy for the environment. Stay tuned for Part 4 where we see the culmination of all the hard work performed for the last 3 months.

Love the concept of earth to earth for building materials. Keep up the great work!

[@Riessu]

It was a really wonderful message ! Earth to earth with a minimum impact .... Only the concrete one ^^ I will surely enjoy your next video without concrete ! xD

[@alexchiperi]

It ALWAYS rains on tatemae! 😀

[@thecarpentrylife]

So true!

[@leemelbourne3297]

Such beautiful pieces of timber. It would be great to work on a build like this.

[@tabbycat8760]

best video ever, thank you so much, oh god i wish i will be building these houses some day, carpentry is the best thing ever

[@paulnibart1870]

That's really cool, thank you so much for sharing ! I wonder what kind of prices one have to pay to build a house like that ?

[@thecarpentrylife]

Thank you for watching. I think the final cost for this house with interior and exterior finishing was around $250k. It was built for a small family (3 people). The house is around 100 sq. meters. (1075 sq. ft.). I would think that the rising cost of wood globally and domestically will probably add around 25% to the cost today. This house was built from Japanese wood purchased in mid 2020.

@@thecarpentrylife do you think wood prices will come down or stay expensive?

[@HandToolsWoodworker]

Thanks for sharing! Which part of Australia 4:53 are you going to?

[@thecarpentrylife]

I believe the build will happen about an hour outside of Sydney. I am not sure the exact location.

[@Theo-zm9rm]

Very nice video ! Do you have the full name of the french carpenter Romu ( 8:28) or any contact ? I'm currently buying a land in France, and i would like to contact him for my project

I have watched numerous videos here on Japanese construction techniques. I am preparing to build a timber frame structure with wood that I have milled, and I am considering the anchor bolts for holding down the sills. At the 7:45 mark in this video (kzbin.info/www/bejne/hKTPemuHi7ugjNE) you can see the nut that gets threaded onto the anchor bolt. Where do the Japanese builders buy these nuts, and why are these nuts preferred? Thanks.

[@thecarpentrylife]

These are zabori nuts that are designed to stay tight in the event of an earthquake. These semi-permanently binds the wood foundation to the concrete formed foundation. The threaded rods are bent rods embedded in the concrete during the pouring process. There is some science and earthquake calculations that are considered when placing these threaded rods. Thank you for watching

[@GingerJohnnyOR]

@@thecarpentrylife I have not found any manufacturer of such hardware that ships to the US...do know where I might find a source?

[@RogierYou]

How much does a traditional build like this cost?

[@thecarpentrylife]

It is hard to say. You would have to quote it in the months prior to building it. Wood prices have fluctuated a lot in the recent year so it would be incorrect for me to give a price.

[@RogierYou]

@@thecarpentrylife just a very rough idea. $250k - $500k ?
