Investigating The Domestic Layers Adaptation During Pandemic, Afifah Karimah, Kristanti Dewi Paramita Jul 2020

Investigating The Domestic Layers Adaptation During Pandemic, Afifah Karimah, Kristanti Dewi Paramita

Interiority

This paper expands the theoretical understanding of building layers proposed by Brand (1995) by investigating changes in the domestic environment during the COVID-19 pandemic. Brand’s layer framework breaks a built environment into “shearing layers” to examine its adaptation processes. This paper argues that ways of managing the risk of virus transmission in the built environment redefine the understanding of these layers. This paper takes the perspective of interiority to address these layers as instruments with the spatial qualities required of a resilient domestic environment. The study unpacks the theory of Brand’s layer framework, proposing the principles by which layers adapt …

The Charms Of An American Queen Anne: Rediscovered A-Lá Covid-19, David T. De Celis Jul 2020

The Charms Of An American Queen Anne: Rediscovered A-Lá Covid-19, David T. De Celis

Interiority

This moment, the 2020 COVID-19 pandemic, has provided an opportunity—sometimes forced via crisis, or via moments of quiet reflection—to consider the inside, interior time and space, in new ways. In America, like other countries, architectural styles have come to us from foreign lands. Numerous domestic structures were influenced by British events from the 1700s–1800s. These styles—these architectures—were transformed by local/regional/national influences and events—events like this current international pandemic—that push the proverbial pause button, and cause us to re-think design. The author, who now resides and works (along with his family) in an 1886 Queen Anne style home, contemplates the various …
