Sandstone House in Bangalore: reclaimed sandstone for a contemplative home

Sandstone House is a residential project by studio 4Brick Studio, built in Bangalore, India, and completed in 2025. Designed for a couple of art and antique collectors, the house uses waste sandstone sourced from the Gwalior Mint quarry.

the project: a home for art and antique collectors

Sandstone House was conceived as a living space designed to house and display a personal collection of art and antique objects, with rooms conceived as a sequence of contemplative spaces where natural light and material texture play a central role in the perception of the interiors.

The clients' collection, accumulated over decades of travel, includes pieces with their own history of wear, patina, and repair, and the design team wanted the architecture itself to share that same sense of accumulated time rather than presenting a pristine, newly built backdrop that would have felt at odds with the objects on display.

waste sandstone from the gwalior mint quarry

A distinctive element of the project is the use of waste sandstone - blocks and fragments deemed unsuitable for standard processing and generally destined for disposal - sourced from the Gwalior Mint quarry. This choice responds both to a sustainability rationale and to the search for an imperfect, non-uniform material texture consistent with the atmosphere the project pursues.

a dialogue between raw stone and natural lime

The reclaimed sandstone was paired with natural lime finishes, creating a dialogue between the roughness of raw stone and the tactile softness of lime surfaces, generating a material contrast that accompanies visitors along the home's interior path.

Lime plaster was chosen partly for its compatibility with the breathable, moisture-regulating qualities of natural stone masonry, avoiding the risk of trapped humidity that can occur when porous stone walls are paired with modern cement-based renders, a detail particularly relevant in Bangalore's humid climate.

imperfect materials as a conscious aesthetic choice

The project overturns the traditional approach that favors uniform, flawless materials, consciously choosing stones with imperfections, color variations, and irregular textures as a defining element of the overall aesthetic, in line with a contemporary sensibility increasingly oriented toward material authenticity.

why stone reclamation is a growing trend

Sandstone House fits within a growing international trend that sees architects and designers taking increasing interest in quarry waste or reclaimed materials, not only for sustainability reasons but also as a source of original aesthetic solutions, difficult to achieve with standardized first-choice materials.

Quarries across India and elsewhere generate significant volumes of stone considered commercially unviable due to size, color inconsistency, or minor structural flaws, material that has historically been treated as waste; architects who actively seek out these reclaimed stocks are helping create a secondary market that reduces quarry waste while also lowering material costs for projects willing to embrace visual irregularity.
