Indian architecture practice Sanjay Puri Architects has used fluid surfaces and S-shaped form to create this house in Gandhinagar, India. 

Named Nine X Nine House, the 1,672-square-metre house is situated on the southern side of a 3,311-square-metre site, while fluid volumes flowing  between nine existing trees, with two of the trees separating the open deck sections.

The home is slowly revealed from the gate as one enters the site, which is situated between a sizable group of trees on the northwest corner.

All of the rooms on the northern side are directed toward the huge garden created by the developed spaces on the southern side. With temperatures above 35°C for the majority of the year and the sun in the southern hemisphere, the orientation is designed to respond to the hot environment that is common in this area.

The house simultaneously creates a "T" shape in both plan and section. With a central spiral staircase at its center, a central spine splits off to the east and west as it is entered from the northern side. The home is divided into two halves, one on the ground floor and one on the upper level.

An open stairway along an undulating wall with a waterfall connects the underground level to the ground level garden, while a spacious sunken courtyard area on the western side lets in natural light and air. 

The areas are passively cooled by this waterfall on the west side and a shallow reflecting pool on the northeast side. Three more trees were kept on the southeast side, and six of the original trees were kept in the sunken courtyard.

The living room, dining room, kitchen, and guest bedroom are all located on the first floor of the house. Three family bedrooms are located on the upper level, each of which has a window overlooking the garden and trees on two sides. 

Entertainment areas and a small gallery showcasing the owners' art collection are planned for the underground level.

Large cantilevered decks that are partially open and half covered open from every room of the home, creating transitional areas that may be used in various ways depending on the weather. During the sweltering summer months, when temperatures can reach 50°C, these deep recesses help to keep the internal volumes cool.

White marble flooring, wood furnishings, and muted accents abound in the interior's minimalistic design.

Because of its energy-efficient construction, the house doesn't need air conditioning for the most of the year. Each section receives plenty of natural light, and the inside is furnished with natural materials, water recycling, and rainwater collection.

The Nine X All of the existing structures and trees between the nine homes are preserved in their contextual design. Because of its orientation and layout, it reduces heat gain and creates spaces that blend in with the natural environment, making it climate-responsive.

Sanjay Puri Architects designed a museum wrapped by grey fluid concrete in the city of Nathdwara, India. In addition, the firm sculpted a house with steep and punctuated arches to respond to the hot desert climate of Rajasthan in India.
