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.

Drawings are in vertical order, so the roof is on top.


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

Second floor.
Note that the large balcony is partly covered by the roof, indicated with a dashed line.

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.
