Digital placemaking embeds digital technology to enhance form, activity, and meaning. The inclusion of digital material into conventional placemaking diagrams indicates gaps and leads to the development of new propositions. This study aims to develop new propositions, principles, and criteria for digitally enhanced architecture for sustainable placemaking. The novelty lies in the new proposition of digitally enhanced architecture by using digital information as a formal material for sustainable placemaking through multisensory experience and two-way user-form interaction. This study uses a systematic literature review method to analyse 38 theoretical and 20 case studies based on constituent aspects (form, activity, meaning) in digital placemaking and media architecture theory to formulate design principles and criteria. The developed propositions are digital information technology as form, reciprocal multisensory interactions as activities, and perception for place meaning. The principle is digital form stimulates users’ sensors to respond via two-way interactions, constructing a perception of place meaning. The criteria are building architectural forms from digital information as a physical setting and stimulating two-way multisensory interactions for spatial perceptions and experiences associated with memory and meaning. These findings apply to places with inaccessible physical forms, so digital information can replace and stimulate interactive activities to construct, strengthen, or restore place meaning.

Ijen Geopark has geotourism prospects from its geosites, biosites and culture-sites diversities. This study aims to give concepts to design an educational geotourism facility that is accessible for diffable people with inclusive design approach. Design process uses force-based framework. Identified forces are accessibility, black lava rocks, site contour, and local materiality. Design method uses regionalism that responds to site and enhances regional characteristics. Tourists get the education through multi-sensory experiences. Circulation bridge is less than 8% incline for independent use by all users, with landing areas as viewpoints. Local bamboo plant stimulates auditory sense. Black lava rocks’ texture is recognized through tactile sensory.

Placemaking transforms space into place by arranging form, activity, and meaning aspects. In a historical urban village context, the physical forms of historical objects are often altered due to space scarcity and growing needs. It could weaken the historical meaning of the place. Digital technologies could represent the lost historical forms or activities as digital placemaking strategies. Combining the Pepper Ghost illusion technique and digital projection produces a virtual layer to represent past events superimposed onto the site's surroundings to strengthen the place's meaning. It provides a practical digital placemaking strategy for urban village communities. This study aims to evaluate the design prototype of the virtual layer strategy by identifying factors that affect design performance and proposing design recommendations. This study was conducted by experiment and prototype testing. Testing with participants involved semi-structured interviews for data collection and content analysis to identify the factors. This study also provides schematic design implementation in Kampung Kungfu Kapasan, Surabaya. The results recommend designing the screen on a human scale, balancing environmental brightness for content clarity and visual comfort, as well as integrating installation design and surrounding elements. The overlapping strategy of past and present conditions forms a virtual layer as a layered enclosure. It affects how users perceive the surrounding environment, thereby shaping their perception of the place's meaning.

Metaphor technique adapting organic shape from nature requires advanced technology for its development. Metaphor with regular irregularity concepts provides better camouflage and harmony within context. Irregularity on bird’s nest metaphor is shown better in section plan. Conceptual thinking by section integrating various parameters requires dominant understanding toward structural context. Design context is a pavilion at Nansha Bird Park, Guangzhou, China. The presence of the pavilion should not interfere bird's habitat. Design purpose is making a pavilion that camouflage with minimum interruption toward site. Design approach applies metaphor technique. Metaphor utilizes natural shape (biomimicry) of bird’s nest as nest for humans and birds. By cutting the pavilion into half, the structural complexity of bamboo construction can be shown clearly. Form finding process is done by digital technology and parametric design to achieve optimal form from desired metaphor. Site contextuality is responded specifically by the utilization of bamboo material and construction. Structural system utilizes interwoven bamboo layers to shape monocoque structure with vector-active system. Exploration is done by Rhino 5 and Grasshopper application. Form exploration focuses on bamboo layers as pavilion's structure. Patterns by Grasshopper’s script are applied to each layer. The pavilion’s shape is derived from basic spherical shapes as a metaphor of bird's nest. The resulting shape is stretched to create more space and split in half to expose its structure. Pavilion design responds to site and climate by considering the relationship of function, material, and bamboo construction parameters. Limitation on parametric concepts makes optimization simulation problems have to be adjusted with constructability.

Architectural heritage interventions often preserve visual form while leaving acoustic memory and everyday sound practices outside the design brief. This article positions soundscape as an architectural material for heritage media architecture and tests it through Sanggar Kungfu Kapasan, a historic Chinese-diaspora kampung in Surabaya, Indonesia. The research combined contextual and soundmark mapping, Pepper’s Ghost prototyping, architectural translation of a semi-transparent virtual layer, and comparative evaluation using 2D visualization and immersive VR. After deduplication, 37 participants evaluated the 2D material, 31 evaluated VR, and 24 completed both modes for within-subject analysis. VR significantly improved perceived physical quality (Δ = +0.46, p = 0.0007, d_z = 0.80), communication quality (Δ = +0.42, p = 0.0218, d_z = 0.50), and overall evaluation (Δ = +0.20, p = 0.0285, d_z = 0.48). Sound-specific VR ratings were positive for place-meaning support (M = 5.87) and scene formation (M = 5.65), and the soundscape design index correlated with communication quality (r = 0.47, p = 0.007). The findings show that soundscape strengthens narrative legibility and architectural fit when deliberately coordinated with visual layering, scene sequencing, and cultural context. The study contributes a soundscape-informed, feng shui-readable workflow for pre-installation evaluation of multisensory heritage interventions. Because the respondent pool was predominantly composed of architecture students, the results are interpreted as a preliminary design-user evaluation rather than community validation.
