House of Voids is a multigenerational residence in Vijayawada that organizes domestic life around a series of open-to-sky voids carved from a compact urban mass. Responding to limited frontage, tight setbacks, and Vaastu criteria, the project turns inward, coupling a recessed public edge with a materially robust envelope and an interior landscape of courtyards that structure program, light, and air.

We treated the house as a carved volume, letting voids rather than rooms set the plan, climate, and daily routines, while aligning with Vaastu without letting it fix the architecture in place.

Urban Interface and Threshold Design
The house meets a dense street condition without a compound wall, a local departure that recalibrates how domestic space addresses the public realm. A narrowing, recessed entry compresses movement before release into the interior, while the inward-bending facade marks a measured threshold that keeps sightlines shallow and street glare at bay. This geometry achieves controlled permeability, acknowledging the street as social infrastructure while preserving interior focus.
At ground level, the base integrates stormwater collection through concealed channels, reading as a discreet plinth rather than a defensive edge. The detail supports street performance by removing surface runoff while extending the facade’s tectonic logic to grade. Given the plot’s constrained frontage and tight setbacks on three sides, the massing deliberately privileges interior orientation. External display yields to sectional depth and the microclimatic work of courtyards, with the entrance sequence acting as a calibrated hinge between the city and a more temperate interior world.
Subtractive Massing and Open-to-Sky Voids
A strategy of subtraction organizes the plan and section. Stacked, open-to-sky voids at the core act as spatial anchors that stitch together three levels through bridges, edges, and staggered overlooks. Their dimensioning and placement are tuned to admit high daylight while avoiding glare, distributing illumination to circulation and adjacent rooms, and ensuring privacy from neighboring properties. By centering unbuilt space, the project replaces a typical stacked-room logic with a continuous spatial field governed by air, light, and view corridors.
The voids operate as environmental devices. Proportions balance width and depth to sustain usability through the day, while the vertical shafts induce buoyancy-driven airflow that draws cooler air from lower levels and exhausts warm air above. Lateral openings and the sectional offset of voids reinforce cross-ventilation. As social condensers, these courtyards host everyday activities for multigenerational living without collapsing privacy, establishing gradients from communal edges to more secluded interiors, and allowing simultaneous, layered occupation.
Envelope, Material Logic, and Environmental Performance
The envelope is defined by dark grey, leather-finished granite assembled as a dry-clad skin, paired with vertical wooden fins. The granite’s low chroma satisfies cultural constraints on pitch-black surfaces while providing durability and thermal mass. Timber introduces tactility and a finer scale at apertures, thickening the threshold and moderating views. Together, they establish a robust exterior with a calibrated interior softness.
Custom brackets allow the granite to project up to 600 millimeters beyond the building line, enabling chamfers and undulations that deepen reveals and create self-shading. These variations act as a thermal buffer, limiting solar gain and sheltering openings from wind-driven rain. As sunlight shifts, the facade registers changes through shadow bands and subtle tonal shifts on the honed surfaces, offering legible environmental feedback across the day. The combined weight of the cladding and the air gap of the dry system stabilizes interior temperatures, complementing the courtyards’ convective cooling.
Cultural Parameters as Design Framework
Vaastu functions here as a generative framework rather than a fixed template. The placement of voids, the negotiation of building lines, and the controlled projections are aligned with these spatial logics while serving climatic and programmatic aims. Material tonality, kept to dark grey rather than black, acknowledges cultural criteria without reducing the architecture to symbolism. The result is a house where inherited spatial rules are worked through tectonics and section.
This approach demonstrates how traditional planning can be retooled for urban density. Courtyards provide environmental regulation and social coherence, the articulated facade manages heat and privacy on a tight site, and the threshold design addresses the street without fortification. By letting cultural parameters set constraints that are answered through constructional and spatial precision, the project shows a path for domestic architecture that is at once contextually literate and operationally rigorous.
About Studio Urban Form + Objects
Studio Urban Form + Objects (Studio UF+O) is an architecture and design practice based in India, founded in 2015. Led by principal architects Prachi Parekh and Vineet Vora, the studio is committed to exploring spatial identities through a lens of cultural resonance, material clarity, and environmental responsiveness. Their design approach often interprets traditional principles through modern forms and tectonics, as exemplified by projects such as House of Voids, which investigates the role of subtractive space in dense urban contexts.
