Architecturally, Mohar Haveli is a fine example of traditional Shekhawati haveli design, blending indigenous Rajasthani building practices with Rajput and Mughal influences. The structure is organized around courtyards, which form the functional and social core of the haveli, ensuring ventilation, light, and climatic comfort in the arid landscape. The facades and interior walls are adorned with elaborate fresco paintings, a defining feature of Shekhawati architecture, depicting mythological themes, floral patterns, local life, and decorative motifs rendered in natural pigments on lime plaster. Architectural elements such as ornate gateways, carved wooden doors, jharokhas (overhanging balconies), and painted ceilings add to its aesthetic richness. The spatial hierarchy—from public areas near the entrance to more private inner sections—reflects traditional social norms of merchant households. The restoration of Mohar Haveli has retained these original architectural characteristics while sensitively adapting the spaces for museum use, making it a compelling example of conservation-led adaptive reuse.
