Heating Pipes and Staircases

Winter greetings everyone - just a week to go until Christmas! Things are certainly winding down here in Japan so this will be one of the final updates for 2019. Yuko and I have another 3 trips over to site in the next two weeks but I can't promise we will be able to get any blogs up. Mum is coming over from the UK for 9 days and we will be out and about touring Japan (she has no idea where we are going yet!).

This week our house was tested for air-tightness using a kind of big mechanical fan and a computer in order to generate the readings. Our builders take air-tightness pretty seriously with insulation and correct sealing a priority at all stages of construction. Their aim in our case was to create a house that 'leaks' less than 1.0cm2 per m2. Our reading came out at 0.6cm2, which some Googling and consultation with other house builders we know tells us is excellent. 

To put that in perspective, another family we know with a Passivhaus-type house in the North part of Japan (much, much colder and snowier than Osaka) had a reading of 0.4cm2. Burning 6 logs on their wood burning stove in the evening keeps their house warm until the evening the next day. If we can get anywhere close to that, we'll be very happy.

Last Sunday we headed over to the house just after lunchtime to discover that the mortar has lightened a little bit since the last visit. The slightly brighter colour looks great, especially when it catches the sunlight. Other than that, the house is pretty much identical on the outside, although the side walls of the penthouse on the roof now match it in colour (this may have happened a while ago but the only place to see the penthouse is by looking back from the second floor balcony, which we kept forgetting to do).

Inside, there are some relatively big changes. Firstly, we now have a staircase from the ground floor to the living room floor. The woodwork looks excellent (although most of it is under protective covering) and the gradient is perfect. Holes for foot lights and switches for turning them on are all where they are supposed to be and the wires are labeled correctly. The cupboard under the stairs looks like it will be spacious and practical. 

The only problem currently is getting up and down the staircase. Since they are still preparing to build the stairs from the upstairs up to the roof, the second floor has temporary boarding in place over the new stairs with a small hole through which to emerge. This means that the second part of the climb from downstairs involves crawling up like a tortoise. Going down is not much easier.

Upstairs, the ducting is now pretty much all in place and mostly boarded over. We were probably lucky to catch it this week as before long it will be completely covered up and we will no long be able to see how it works. I'll use the photos below to explain it as best as I can:

The black thing is the fan that draws warm air from the living room upstairs through the long silver pipes hidden within the ducting around the top of the room. This fan will eventually connect up with a downward pipe on the LHS of the picture above which will transport the warm air downstairs. It is then released through vents in the downstairs floor, heating the downstairs areas of the house. The hot air then rises and is blown back down again, creating a cycle.

Here you can see how the pipe runs inside the ducting. A few more days and this will all be covered up.

Here you can see how the ducting runs along the top of the room. It has encroached a little bit on the highest point of the ceiling and the room does feel a bit different now it is filled in, although it actually frames the space quite well I think.

At the top is the little window through which the hot air will pass into the pipe.I guess it is going to have some kind of vent or grate across it rather than just a hole. Interesting that such a simple looking hole in the wall hides a relatively complex system behind it.

Pretty clever eh?

I guess that's where I should wrap up for this entry. I'll put the remaining photos we took below with a comment under each as per usual. I'm hopeful that I will get another entry up before the end of the year but you never know. Time always seems to get away from me in December. If for any reason I don't manage it, have a very happy Christmas and a great start to 2020.

First Planning Meeting


There have been a number of stages in the process to date that have generated excitement. Receiving the phone call to say that our land offer had been accepted, our first meeting with an architect, our first show home visit etc. etc. None of those could quite match, however, the excitement of the first planning meeting. This was the first real chance to explain and discuss what we wanted in detail and to start sketching out what we hoped would become our dream house.

The meeting would take place at K’s offices with the architect...oops. As I type this, I’ve just realized that our architect is also K. Right, executive decision time. K the architect is going to become A the architect (for architect, obviously). Let’s hope we don’t meet any Aono-sans or Aoki-sans later in this process!

We sat down with K and A and they started by asking us some more questions about our budget. This is not something we intend to discuss in much detail on this blog so let’s just say that we gave a modest figure that was below our maximum budget but enough, we hoped, to get us started and designing something close to what we want. All seemed pretty fine so far.

As we went through the features that we wanted to include in our house, it should be noted that, unlike with the builder who we had rejected, it was us providing all of the detail as well as showing photos, giving descriptions and indications of size. We were only questioned when something wasn’t communicated clearly, when we hadn’t provided enough detail or when they wanted to offer us some advice. No lifestyle coach questions this time around thankfully!


The list of stuff we mentioned in our meeting. English below!

I’m not exactly sure how to write up the specifics of the meeting so I think maybe the best way is for me to just give a list of what we want in our house and a brief explanation for each thing. That’s the important bit anyway, so here goes...

Downstairs

l  Porch area – useful for leaving umbrellas, buggies, muddy shoes and for having a covered postbox. No fetching the post in the rain!
l  Genkan (玄関) – A must in any Japanese house. A place to take off and put on shoes. In Japanese houses you never wear shoes inside (unless of course you are in a rush and forgot to turn the air con off but otherwise NEVER). We want a spacious genkan as it’s the first thing you see when you get home and, as any mother will tell you, first impressions are important.
l  Master bedroom – Size not hugely important but must have enough space for a Western bed and a couple of bedside tables. Dressing table space is a nice-to-have. We are adamant that we want a reasonable sized walk in closet. Right now, we have a kind of walk in closet/pantry/storeroom and it’s not big enough for all our clothes.
l  Kids’ bedroom – Since we don’t have kids yet we want a space that can be multi-use and could be adapted depending on how the future pans out. We decided we want to leave this space as open as possible for that reason.
l  Study – Since moving to Japan, I’ve never really had space for a desktop computer and, as such, a lot of work gets done on a laptop in the living room or at the kitchen table. We want a study which will have enough space for 1/2 computers as well as to store our books, paperwork and files. We want it to be big enough for a sofa bed and coffee table. If it can function as an overflow guestroom, so much the better.
l  Laundry Room – A rarity in Japan but becoming more popular in recent years. Washing machines are often placed in the bathroom (sometimes even outside) but, having introduced Yuko to the concept, she seems sold on the idea of having a small space for the washing machine, ironing clothes and for storing cleaning equipment and supplies. Important that this room has easy access to drying area outside.
l  Bathroom and Toilet – I was happy to have the toilet in the bathroom as per most Western houses but Yuko considered this sacrilegious and so I was quickly put in my place. The bathroom is one area we thought we could probably economize a bit. Neither of us takes baths often so a small Japanese-style tub/shower room would suffice. We used the words ‘cheap’ and ‘simple’ a lot. 

Upstairs

l  Kitchen/dining area – Large open plan kitchen with island and attached dining table. We want the island to have a bar counter with bar stools for breakfast and morning coffees. Some discussion as to whether to put the hob or the sink on the island but we suggested the sink at the meeting.
l  Wine cellar – The piece de resistance of the upstairs floor. We (mainly Tom) want to have an area where we can store and display wine. Three reasons for this. We like wine, it looks nice and the Japanese climate is horrendous for keeping wine so it needs to be stored properly. We (again Tom) showed pictures of professional-looking restaurant-style glass wall wine storage which were met with raised eyebrows. Plan B would be a wine room of some kind. Plan C a wine cellar fridge and bar area. Watch this space.
l  Living room with wood burning stove – Perhaps a nod to British winter culture, a coincidence that our builder is a specialist importer of stoves or a pragmatic heating solution, either way we have decided that we have to feature a wood burning stove in the house. Luckily, the builder produces lots of off-cuts when building houses so he has promised us a lifetime’s supply of free fuel as long as we are prepared to drive the 2 minutes down the road to get it!
l  Tatami-room – We want a traditional Japanese space called a washitsu (和室) or tatami room. The floor of this room is covered in tatami or Japanese traditional reed mats. Very important for special occasions and doubles as a sleeping space for Japanese guests.
l  Pantry – separate room for food is really important as we often shop at Costco (Western food is much cheaper there than in regular Japanese stores) so we need plenty of space to put all the pasta!
l  Upstairs toilet
l  Large outside balcony – We had seen this at the show house and decided that we also liked the idea of a raised outside space on the upstairs floor. This seems like an obvious inclusion until you read the next part...

Further Upstairs (!)

l  Roof Terrace – Since where we are building has some incredible views over Osaka, we want to make best use of this. There is a house directly to the west of our plot (albeit with significantly lower foundations due to the gradient of the road) but we want to maximize our view as best we can. As such, we want to build a large roof terrace where we can enjoy sundowners and maybe a bite of food. We had absolutely no idea how to work this and so made the request, stressed its importance and left it in the hands of K and A.

That’s the laundry list of house features more or less. There’s probably a few small things that I’ve forgotten and I’ll leave thoughts about outside the house for a later post but hopefully that gives a reasonable impression of what we are trying to do.

A few additional points:

-       We stressed that we want to go for (slightly more expensive) sliding doors where possible as these are a much more efficient use of space.
-       Several specific larger storage areas rather than lots of bits of small clever storage in unusual places which seems to be a bit of a trend. (How do you remember where anything is!?)
-       Nice wood in most areas. Cheaper wood in kids’ spaces.
-       Simplicity and open space wherever possible.

I’d say that this has become quite a long post already so I think I’ll leave it there for today. Soon you’ll see our laundry list turn into our first plan! Stay tuned!

竣工 - The End :-)
