A bridge over a stream connects the two sides of this concrete house in India by Mumbai firm Architecture Brio (+ slideshow).
House on a Stream was designed by Architecture Brio as a weekend retreat near the town of Alibag, on a site with a stream meandering through it.
The architects chose to separate the master bedroom from the main part of the house containing the kitchen, dining room, living room and guest bedroom by arranging them on either side of the stream.
Monolithic concrete boxes containing the various rooms rest on the uneven ground and cantilever over the water, while trees grow in the gaps between.
"Like an organism trying to make most use of its resources and surroundings, the house with its several limbs reaches out into the landscape, making full use of the views within the site and dramatises special moments: a beautiful tree, a view of the mountains beyond or the cascading stream during the monsoon rains," said the architects.
A walkway covered by a pergola links the bridge with the entrance to the larger part of the house. Next to it, a narrow swimming pool follows the course of the stream and adjoins a sheltered verandah that becomes an extension of the dining room when sliding doors are pulled back.
The living room and both bedrooms also feature doors that can be slid or folded back to open these spaces onto outdoor decks that bring the occupants closer to the surrounding nature.
The kitchen is located at the centre of the house, with a high ceiling containing a skylight contributing to the bright space, around which the other rooms are arranged.
By offsetting these surrounding rooms and raising the level of the living area, the architects intended to give each space a sense of autonomy, while strategically positioned windows create views from one part of the building to another.
Concrete cast against wooden planks gives the building's exterior a textured finish, which will be enhanced as it gains additional patina over time. The natural aesthetic is enhanced by timber screens that cast delicate shadows on the floors and walls.

House on a stream
Landscape
With a stream running through the house, this retreat in Alibag is delicately woven into the landscape, alternately opening up and closing itself to the different characteristics of the site.
A multitude of medicinal and fruit bearing trees provide for an intimate ambiance and comfortable microclimate. Though seasonal, the stream bed allows for an interesting landscape feature throughout the year. The house is placed on the banks of the stream where it makes a sudden S-curve. A short walk along the stream before entering the house builds up an element of anticipation.
Like an organism trying to make most use of its resources and surroundings, the house with its several limbs reaches out into the landscape making full use of the views within the site and dramatises special moments: a beautiful tree, a view of the mountains beyond or the cascading stream during the monsoon rains. What started out as a Cartesian response to the site became deformed, stretched and pushed in.
Program
The house consists of two parts: the day areas of the house such as the dining/kitchen, the living room and entrance verandah are separated from the master bedroom by a bridge that spans across the stream.
Since the owners are passionate about cooking, the kitchen is made the heart and centre of the house, a large, inviting volume with a high ceiling and a skylight that floods the space with light.
This space forms the anchor of the house from where its various limbs branch out into the landscape around existing components of the site. The living room on the left is lifted off the ground to have a panoramic view of the mountain range in the distance. The guest room embraces an existing tree to create a courtyard and just peeks across the dining room to have a view over the length of the stream. The pool is aligned along the stream acting as a celebration of it during the monsoons, and a memory of it during the dry season.
Orientation
The orientation of the program is based on climatic considerations. The bedrooms are mostly west facing with large verandahs and get the evening sun.
The living rooms faces east once again with a large verandah. The kitchen, dining, and pool areas all look towards the north and are shaded by large trees. The south façade of the house is predominately closed and more solid with the exception of a picture window that frames the view out from the pantry to the fields beyond.
Monolithic character
While the external structural concrete shell contracts and expands in plan in section it does so as well. The external form of the house responds to site and its orientation and flows from high to low in accordance with the monolithic fluidity of its form. Internally, however, it responds to the creation of space, and directs the eye to frame a particular view.
The outside and inside are therefore apart and internal spaces are defined with volumes created by the changing thickness of the internal ceiling.
The heaviness of this mass however is reversed by the lightness of the white washed walls and ceilings. A central skylight and large sliding doors, which span from floor to ceiling and wall to wall bring in the outside into the interiors. The cantilevered ‘limbs’ of the living room and two bedrooms defy the heaviness of the concrete volumes. By not resting it on the ground the relationship with the landscape paradoxically is strengthened.
Internal relationships
A series of asymmetrical axis create a path of discovery through the house. The arrival path is aligned with the axis of the pergola, which embracing the pool enters the dining room on the left side. One corner of the dining room overlaps with the conically shaped volume of the kitchen. By shifting the axis of the dining room off the axis of the kitchen and raising the level of the living room, this becomes a more secluded space.
Furthermore it allows a glazed door in the kitchen to open up to the outside and view along the external living room wall. At strategic positions in the house steel framed box windows protrude through the concrete walls. Placed symmetrically on the interior walls they highlight specific elements of the site, such as the bark of a tree, or peek from the master pavilion to the main house.
Materialisation
The house is cast in plank-finished concrete with a vertical grain. The homogenous materialisation emphasises the sculptural quality of the house that is moulding itself about the site. Concrete being left exposed in the humid Indian climate, attracts a patina that becomes more rich and alive over time. More so the grey textured surface provides a muted surface against the vibrant green surrounding.
Elegant timber screens further soften the greyness of the con- crete. They not only form a buffer between the interior space and the exteriors, but also create an intensive play of shadow and light on the floors and walls.
