The different parts of a nallukettu house are
- Padippura – Characterized by a step and tiled roof, padippura is the entrance to the compound. This is one of the most distinguishing features of the structure with a top naalukettu gate, consisting of an elaborate, temple-like gopuram.
- Poomukham – A space that has tiled roofing with supporting pillars.
- Chuttu verandah – A corridor that runs around the house.
- Nadumuttom – the central courtyard of the structure that is open to the sky. The most interesting aspect of this part of the home is that it houses the holy basil, the auspicious tulsi plant in the center exuding positive vibes.
- Pooja space – Ishana, the north-east corner of the house, the space where both wisdom and wealth reside in a home, the idols of the deities face either east or west.Nalukettu houses were typically made of teak wood. Most of the materials used in the construction were sourced locally, these included wood, red bricks, and mud.
These homes had excellent ventilation and lighting which kept the house well aerated and lit up at almost all times of the day. Gabled windows on the top of all naalukettus always ensured cross-ventilation and allowed enough light into the attic, while extended rafters gave ample protection from the heavy rains that are characteristic of kerala.
