Project Description

As the name suggests, this house was designed to bring in the presence of the five elements of nature , Earth, Water, Fire, Air and Space into the building. Water bodies, internal courtyard, large windows, use of natural materials etc connects the inhabitants to these elements. The house is a zero energy development with closed loop systems for Building materials, Processes and Technologies just like nature.

Climate Analysis


Bangalore has a tropical savanna climate with distinct wet and dry seasons. Due to its high elevation, Bangalore usually enjoys a more moderate climate throughout the year, although occasional heat waves can make summer somewhat uncomfortable. The coolest month is December with an average low temperature of 15.4 °C (59.7 °F) and the hottest month is April with an average high temperature of 36 °C (97 °F). Winter temperatures rarely drop below 12 °C (54 °F), and summer temperatures seldom exceed 37 °C (99 °F). Bangalore receives rainfall from both the northeast and the southwest monsoons and the wettest months are September, October and August, in that order. The summer heat is moderated by fairly frequent thunderstorms,

Design Approach


The presence of the five elements of nature: water, air, earth, fire and space in a building results in the development and balance of all the three faculties of man, i.e. the psychological, physical and spiritual. This was the defining principle of the design. The house is an improvised example of the traditional Kannada home “Thotti Mane”, with an internal courtyard.

The house has an E-W orientation due to site dimensions and spaces are arranged according to the day lighting and ventilation required. The existing slope was transformed into a landscaped waterfall directing the rainwater into the lotus pond.

The house is spread along the east-west direction, facing north. A two-level open to sky courtyard with a waterbody - Thotti, open kitchen and dining with a double height enlivens the environment of the house. The interior spaces seamlessly merge into each other producing a calm relaxing ambiance. The house has high ceilings and ventilators throughout the house to ensure enough draft for thermal comfort continuously.

Special Feature


Large windows, increased floor heights and use of skylights ensure optimum daylight.

A Rainwater Harvesting sump of 75,000 ltrs DEWATS system has been used for water treatment and 500 ltr/day of recycled water is used for gardening and flushing after treatment. Water bodies within and outside the building are fed by Rainwater. Water saving fixtures for taps.

Ventilators on each window and door ensure cross ventilation of spaces. Use of terracotta, filler slabs, mud blocks and stone in the building keeps the interiors cool. The presence of an internal courtyard with a water body maintains humidity and enhances the comfort levels.

Local, recyclable natural materials like bamboo, stone, mud blocks, terracotta and local labour are used for construction, making it extremely cost effective.

Mud blocks made from excavated soil are also used for filler slabs, reducing the amount of concrete required. Use of locally available variety of Bamboo and stone for construction. Collection of rain water. Treatment of waste water Solar PV for power Solar water heater for hot water Daylighting Natural ventilation

A large 3500 sqft double curve shell roof on all bamboo support is a novelty in the building. It lends the interiors a very pleasant and cool ambiance.

Building Material


Bamboo poles as columns and beams and bamboo splits for under structure for the shell roof; composite load bearing and frame structure with filler slab for intermediate slabs; Stone and mud block masonry and bamboocrete wall for interior partitions and first floor walls

Concrete foundation columns for Masonary foundation for Compressed stabilized earth block masonry walls. Bamboo column has 2' x 2' x 2.5' concrete footing with ms pipe at the center to anchor the bamboo to the footing.

Load bearing compressed stabilized earth block masonry. Prefab Bamboo-crete walls for partitions.

All doors are wooden. Windows with wood frame, glass panels and louvers for ventilation. All wood used is certified wood bought from auctions of the forest department

Granite flooring for living room and terrazzo, oxide, marble flooring for bedrooms; Bamboo flooring for informal living, Son's bedroom, Staircase and Stair room flooring with waste wood

Lime wash for all the mud and bamboo crete walls for the interiors; Bedroom interiors with PEP finish; Bamboo members finished with Touchwood coat. Exteriors are exposed mudblocks with silicon waterproof coat or lime wash.

Filler slabs with mud blocks for flat roofs. A 3500 sq ft lightweight double curve concrete shell roof with a span of 8.5m-10m and length of over 45m is supported by bamboo columns and beams. The roof itself is reinforced with a bamboo-split mat. A Tarpaulin painted on one side is above this split bamboo mat, acting as a water proofing member. Hollow stabilised compressed mud blocks made from excavated soil have been used for filler slabs, reducing the amount of concrete required. They have been used in the particular design for thermal and acoustical comfort, and it has worked successfully. Bamboo splits mat over round bamboo beams and columns for under structure of the shell roof.

The house is a modern rendition of a traditional Kannada house incorporating the solar passive elements.

Lessons Learned


The house has been used for various experiments with natural and low energy building materials and Construction technologies. Bamboo crete walling is used effectively for partitions. The unique 45m long double shell roof uses Bamboo-split mat and Bamboo fiber reinforced concrete, new technologies that have stood the test. This huge roof rests on Bamboo supports, proving the strength of Bamboo. It could be used for large constructions like stadiums, community halls, etc

The house feels very peaceful and welcoming like a temple after a long stressful day out. It feels cool in the summer and warm in the winters. The natural light, ventilation, vegetation, water features gives it an atmosphere of a peaceful idyllic resort.

The house is an example of a high end contemporary home with low end materials and traditional values at extremely competent cost without any compromises.
