Quick Answer
A Nalukettu house is a traditional Kerala home built around an open central courtyard called the Nadumuttam. Its design emphasizes natural lighting, ventilation, thermal comfort, and functional living spaces. Known for its wooden construction, sloping roofs, and balanced layout, the Nalukettu style remains an enduring example of sustainable and climate-responsive architecture.
What is a Nalukettu House?
A Nalukettu is a traditional Kerala house designed for large joint families. It has an open space in the center called Nadumuttam. Rooms are built around this open area, covering all four sides. The big open space in between the rooms lets sunlight and fresh air in, so the house will be cool and bright.
Family members can occupy this courtyard for their family reunions, conferences or any other purpose of their choice. These homes are not only beautiful and functional but also very representative of Kerala’s culture and intelligent design. Nalukettu houses continue to fascinate many with their peaceful environment and natural way of life.
Components of a Kerala Nalukettu Home
Several components of a Kerala Nalukettu home are as follows:
1. Padippura (Entrance Gateway)

Padippura is the main entrance to the house, built into the boundary wall. A tiled roof on top of it gives them a traditional look. Earlier, it had a door, but now it’s open to allow vehicles to enter. A small traditional lamp is often placed under the roof for decoration.
2. Poomukham (Main Veranda)
Poomukham is the front veranda of the house, located just after the staircase. The wooden pillars support the sloped tiled roof and keep the sides open. In ancient times, the head of the family (Karanavar) used to sit in the reclining chair along with the spittoons. The chair had long rails on the sides for leg support, ensuring comfort.
3. Chuttu Verandah (Side Passageway)
From the Poomukham, an open covered walkway extends along the front of the house. This passage is called Chuttu Verandah. It usually has hanging lights spaced evenly from the sloped roof, adding to its beauty.
4. Charupady (Wooden Benches)
Next to the Chuttu Verandah and Poomukham, there are wooden benches with decorative carved backrests. These benches, called Charupady, are used by family members and guests to sit and relax.
5. Ambal Kulam (Sacred Pond)
At the end of the Chuttu Verandah, there is often a small pond with sloped sides. This pond, called Ambal Kulam, is used to grow lotus flowers (Ambal). It also helps maintain positive energy around the house.
6. Nadumuttom (Central Courtyard)
Nadumuttom is the open courtyard in the center of the house. It separates the house into four parts and provides rain, fresh air, and sunlight to penetrate. The open space provides positive energy and natural ventilation. Tulasi, or holy basil, is grown in the center, cleansing the air. Ettukettu and Pathinarukettu are the two or four courtyards in some larger houses.
7. Pooja Room (Prayer Room)
A dedicated place for worshipping is placed in the northeast corner of the house. Face the idols facing east or west, and when you are praying, stand in the reverse direction. The walls often have wooden paneling to create a sacred and peaceful space.
