Last week we examined the three room layouts that evolved within the tatebunwari pattern, where the basic principle of room division is that of transverse ‘columns’ across the dwelling - the room adjacent to the doma (typically called the hiroma) bounds the doma for its full width, and the rooms further ‘in’ are generally parallel to the hiroma and also span the full width of the dwelling. This week we will look at the other subgroup of three room layouts: those that developed from the yokobunwari pattern, where room divisions are longitudinal, and more than one room bounds the doma.

The first subtype of the yokobunwari pattern is called the mae-zashiki-gata 前座敷型or ‘front zashiki’ type. In the example of this type shown below, we have the front zashiki of the title, where more formal or public-facing activities would take place, and also possibly more utilitarian activities in the area of the zashiki bordering the doma. To the rear of the zashiki are two rooms: the doma-bordering daidoko 台所, where eating of meals and other household activities were undertaken. The daidoko might also be used for sleeping. At the most ‘interior’ part of the dwelling is the nema 寝間, used mainly for sleeping.

The *maezashiki* type, *yokobunwari* pattern.

The second type is called the tatenarabi sanma-dori 竪ならび三間取り which I will call the ‘row type’ in contrast to the ‘column type’ discussed in the last post. Here the three rooms are arranged parallel to one another so that each borders the doma on their short side. The example below is typical, with again the front zashiki, the middle daidoko, and the rear heya for sleeping.

Analysing these patterns and layouts and contemplating the possibilities inherent to each pattern and type can be a productive exercise for any architect or designer. Without corridors or other distracting auxiliary spaces, they have the purity of architects’ schematic bubble diagrams, but made real; there is an appealing directness and clarity to the functional and spatial relationships they contain.
