katsuhiro miyamoto architects: residence renovation in osaka

the latest undertaking by katsuhiro miyamoto architects is a renovation project of a 27 year old wooden residence built in a low storey and high density area of southern osaka city. using undulating lattice surfaces that employed one thousand 2 by 4 wood pieces, miyamoto was able to address key problem areas of the building. three spot gardens integrated with the interior space was established to increase the amount of light and wind that enters the building. meanwhile the lattice surfaces which are able to tilt slightly inwards and outwards with rotating blades help to create a more spacious appearance as one is able to move them to combine multiple spaces together. the lattice surfaces also double as seismic reinforcements against natural disasters.

the lattice surface blades are composed of a round chamfer, which is a 45 degree angle cut on the shorthand side of the visible wood. this creates smooth pleats in spite of the continuous curvature.

the lattice surfaces not only provide character to the space but also double to give a functional use. for instance, the large gaps created between the uneven lattice surfaces and the structural walls allow ideal space for the installation of storage.

an elegant moire effect is created via the incoming light between the lattice surfaces. during night time, interior light shines outwards, thus, acting as streetlight for the public pathways.
