Plans of Proposal 7
Roof plan
Second floor. Main bed room and study.
Walk in closet is reintroduced. Toilet is swapped with washing room.
Groundfloor
Basement. Steps down to frontdoor in same layout as first design.
Materials
The front façade will be made of brickwork. Brickwork is less commmon in Japan than in the Netherlands. Most brickwork look alike buildings in Tokyo are clad with tiles or brick strips. The real thing (picture above) can be distinguished in the details.
Especilally on corners the true thickness of the brick is revealed. A real brick has length - width - height proportions of 4:2:1. As the above image shows these bricks are merely thick tiles.
Another distinguishing detail in quality brickwork is the appearance of the joints. Real brickwork has fully mortared joints (see far above image) whereas most fake brickwork lacks sealing of the joints. The above image only has sealing left under the top ledge.
The color of the sealing mortar has a major influence on the appearance of the façade. A light mortar will fade the color of the brick. A dark mortar (or none) will create a starker color.
The basement of the house will have a 'solidity' outlook. For this we could use natural stone.
A cost saving alternative is fair face concrete.
The garage shutter shall have a color that matches the basement façade.
Example of a wooden bay window.
Corner detail of standard Japanese façade planking.
To be used for the south and north façade.
Roof will be covered with standard Japanese shingles.
The bay on the east side of the house will have the image of stacked limestone blocks. In Holland this is made with plasterwork with sculptured joints. For this project we could use panels which give the same image.
Studies on 2F, option 5 and 6
Looking for options for a study and two bedrooms in the second floor.
Solution by splitting the bathroom in two sections, combinations with the toilet.
Major change by bringing the laundry balcony to the south side. These changes are combined with an extension of the footprint by 60 cm in east-west direction. Thus we can create more storage room and have e more fluent plan.
Façades of Proposal 4
Proposal 4 for the façades is mainly a study on cost saving
by means of reducing the number of windows.

Review of Proposal 3
Main issue is to check the budgetary frame now!
Design issues:
The bay window is considered built-up area. In order to avoid this its depth should be less than 50 cm. The floor of the bay window should be at least 30 cm above the adjacent floor level. This is good news as it may help create free height for the access of the basement garage.
The counter in the kitchen is open to the living room. Look for options for a walk through along the façade.
The two doors to the terrace may be wider, structure allowing it. To be checked.
Basement flat: preferably the size of the study and the size of the bedroom are to be swapped. Toilet can be cancelled.
On the second floor a small study is requested. The program is revised in: 1 main bed room, 1 small bedroom and 1 small study. The bedrooms may have a higher ceiling or even be open to the roof (loft) as height restriction allows this. Both the corridor and the bathroom are considered big to Japanese standards.
Also a narrow balcony along the second floor will be appreciated. As long as it is less than 1 meter wide it will not be counted as built up area.
The current design of the skylight in the bathroom, the toilet and the staircase is much appreciated.
It has been said that Belgian bricks are available in Tokyo. To be checked with the co-architect.

The glass roof on the northern side covers the bathroom, the toilet and the staircase.

Basement.Envelop
This is the "envelop". It shows the height limitations in order to allow sufficient sunshine on the neighbouring lot. In our case we may build 5 meters high on the most northern boundary. From there the maximum height increases with 60% of the horizontal distance to the northern boundary.
The dashed line showes the water table in the ground.
