What Doors Solve, and What They Cost
In a house with a dedicated puja room, an open mandir is the better object: nothing between you and the deities, air moving freely, smoke rising away. In a flat where the puja space shares a room with the sofa or the study desk, that same openness becomes a daily compromise. The mandir is permanently on display in a room being used for other things, it collects that room's dust, and there is no way to close it when the household is away. Doors resolve all of that, which is why this design has them and why it is built tall and narrow rather than wide.
They also cost something, and we would rather say so than let you find out. A closed box traps what burns inside it, so a sealed mandir develops smoke darkening on the interior faces far faster than an open one. The answer is not to pretend otherwise but to build the carcass with ventilation at the back and above the canopy, so air moves through even with the doors shut and smoke has somewhere to go. The inlay on the doors is worked in a pale material set into routed recesses in the teak rather than painted on, so the symbols stay crisp for the life of the piece instead of wearing off the surface. Every element is carved, inlaid and polished by hand by master Indian artisans.
