Home has multilayered characteristics integrating memories, desires, intimacy, privacy, identity, function and even language
[50]. The domestic environments reflect occupants’ behaviours because of their numerous physical, psychological and social contextual experiences (Figure 9). The domestic environment has various purposes and meaningfulness related to occupants’ spatial and environmental factors. Generally, a domestic environment is the combination of three types of spatial zones (e.g., public, semipublic and private) distribution
[43]. The domestic indoor environment can be connected with the external outdoor environment. Each area of a domestic environment has its different spatial and environmental factors that may accelerate occupants’ psychological responses
[4][51][52]. These factors in the domestic setting are associated with occupants’ preferences (e.g., needs and demands). Moore (2000) illustrated that domestic environments reflect diversities of occupants’ preferences due to their living experiences
[53]. Caan (2011) described that human experiences are essential in indoor living spaces to mediate tangible and intangible design factors
[2]. Graham (2015) addresses the different issues of human perceptions related to the domestic environment
[4][52]. Sussman (2015) and Hollander (2021) emphasises the need for understanding human cognitive experiences in the creation of living environments
[44][45]. There are different types of human experiences (e.g., physical, mental, emotional, spiritual, social, subjective and virtual) in built environments. Occupants’ living experiences are different in every step of their life activities
[2][3][54]. From the literature review, it has been identified that human factors e.g., privacy, variety, identity, control, order, security, choice, sociability and aesthetics in different living spaces of a domestic environment influence occupants’ psychological experiences relating to their spatial and environmental needs and demands
[2][7][55]. From the literature, it has been identified that the overall indoor environmental components such as light, colour, temperature, ventilation, materials, layout, shape, size, height, ergonomics, opening and greenery affect occupants’ psychological responses negatively or positively
[2][41]. Other indoor air qualities such as dust, mould, moisture, odours, pollutants and dampness are directly related to occupants’ physical and mental wellbeing
[2][5][41]. Occupants may prefer to control these issues according to their preferences. The outside environmental relationship through openings, window, balcony and toilet attachment may create a spiritual connection with occupants’ minds
[3][6]. Domestic satisfaction or comfort depends on the occupants’ needs and preferences closely related to their spatial and environmental factors in living environments
[43].
