The 9-Tsubo House With Kids? [That's 320 sf, btw]

9tsubo_house.jpgHaving a kid in a 400-square foot apartment? That's nothing. In Japan, they've been designing houses for kids plural to fit on 320-sf lots since 1952--and loving it.

A Japanese firm Commdesign has commissioned several architect/designers to create variations on a "minimum house" concept called the 9-tsubo house [tsubo is a unit of measure equal to the size of a tatami mat, about 35-sf] originally developed in 1952 by the architect Makoto Masuzawa. People can then order semi-customized versions for between $120-170,000.

This year's design [those Japanese also love buying houses online using only tiny little images--or maybe it's shown actual size?], by life+shelter, a Tokyo firm run by an architect couple (with two kids), addresses the theme, "living with kids." They set out to create a space that is fun, safe and has low ecological impact. Their model house went on display 10/1 at D-Akihabara, an old middle school that's been converted into a design museum.

While all these websites are in Japanese, you can run the URL's through Excite Japan's translator for a decent English approximation. [for English, change the option under the URL box; it's default setting is for E-to-J translation.]

My wife and I lived in a 3.5 tsubo "monthly" apartment in Yokohama for 7 months... after that, I think I could handle a spacious 9 tsubo with the kid.

You've seen Japanese cribs, high chairs, etc... very compact. I'm sure that a family could use the space a lot more efficiently than the equivalent space in North America...

One tsubo is roughly the size of two jo, or tatami mats. A 9 tsubo space is about 19 mats, give or take. 19 jo is a lux space for young single folk...

[d'oh, thanks. and it appears the 9-tsubo thing originally referred to the lot/floorplate, not the interior (some of the designs have up to 17-tsubos of floorspace). It's also the case that there aren't enough lots that can accommodate the 3x3 house in Tokyo, so they had to make weird-shaped versions, too. -ed.]

Greg got the "tsubo=1 tatami" wrong, but he was right about the sqare footage; one tsubo is about 36 sq. feet...

I think the Japanese interior layouts do make pretty efficient use of space though; things like sliding doors, miniature appliances, etc make a huge difference. I guess the downside is you usually have a cramped refridgerator and no oven...

G;day...... having trouble with the websites.. trying to find pictures of interior of the updated Sumire-Aoi 9 Tsubo house.. apartently retro fitted to have bedrooms for the twin girls on the second floor.

Any other websites that you know of with floor plans?

Thanks, Ben
