SHREENATH- Kamahalli- COURTYARD HOUSE
Kamahalli is a small hamlet in Nanjangud taluk in Mysore district located 34 km from Mysore and 19 km from Nanjangud. The day when the client, Mr. Shreenath walked into the R-LEEF architect and consultant’s office with a handmade model of their dream house we interns knew we had a client who knew what exactly he wanted. Under the mentorship of Ar. Rajesh Kumar Jain we set to work and put forth the designs which would blend with the environment. During our visit to the site, we had the opportunity to see cob houses that were more than a hundred years old we also had the opportunity to see an old underground granary used to store grains in a natural way to preserve grains for a long period of time.

Vinay Ramanath’s residence is a traditional design built with stabilized interlocking Earth bricks and natural stones like Bethamcherla, Kadapa, Tandoor, and Granite. Kadapa stones are used as the base for small span roofing, tandoor stones are used in stairs and veranda benches. The use of Maruti clay blocks in the filler slabs has made the structure thermally insulated and thus low energy-consuming. The use of cement has been drastically reduced because of ISMB material. Reusing the old wooden window frames and shutters adds to the eco friendly and cost effectiveness of the structure. Most of the building materials are locally sourced. All the above inputs have reduced the carbon footprints of the overall project.

TEMPLE
RENOVATION
Shri Kameshwara Temple is located on the banks of the river Nugu in Kallambalu Village HD Kotte Taluk Mysore District. This temple is estimated to be around eight hundred years old the superstructure is at present buried in the soil to a depth of around five feet.
The temple has been renovated once but the older folks in the village do not remember when and say it was during their elder’s time suggesting at least a hundred years back. A stone inscription however suggests that the temple ‘Punarchetana’ was done in the year 1872 subsequent to which buttresses and iron clamps were put up to hold the temple falling apart from the vegetation grown profusely in and around the temple remanences of which are still present.
The village representatives have approached R LEEF Architects and Consultants Mysore to conserve the temple and bring it back the temple to its past glory

The architect’s team from R LEEF led by Ar. Rajesh Kumar Jain went around the temple complex and made a visual assessment of the structure and chalked out the process of collecting documentary and physical evidence for further analysis to evolve strategies and options for the conservation project and its implementation
The evidence collected in the form of measurements and photographs was analyzed and necessary drawings of the temple layout the positioning of the columns and the section of the temple were drawn. The important aspect of the tilting of the walls due to the growth of vegetation on the roof of the temple structure which apparently looks to be the cause of structural deterioration was measured and analyzed and documented. In continuation with the conservation process, the requirements for the retention of the signs are to be developed along with strategies and options for the final implementation.

The architectural intern team under the mentorship of Ar. Rajesh Jumar Jain from R-LEEF Architects and Consultants Mysore visited the temple site on 09 March 2022 and 18th & 19th April 2022. In accordance with the principles of conservation went about the conservation process is based on architectural conservation. The team after understanding the place gathered evidence both documentary and physical. The measurements of the entire temple complex including the buried portions were measured. Necessary excavations to study and measure the structure were undertaken. A detailed measurement record of the site has been documented. The architectural skills of free-hand sketching of the interns came in handy for collecting the documentary evidence of the conservation project.

SKYLIGHT Between the living room and dining, a hall skylight is provided which helps have more light into the semi public area. A natural waterfall using rainwater is also done on the wall to enhance the aesthetic of the building PARAPET The parapet wall’s combining jail and clay blocks, Kadapa for coping
The entire surrounding landscape i.e., the trees, vegetation, and ponds, significantly compliment the building by adding serenity and beauty to the ambiance and providing fresh cool Amongair. the rich landscape are trees bearing mangoes, coconuts, sapotas, bananas, papayas, avocados as well as bonsai, and innumerable flower species.
GREY WATER RECYCLING
There are 3 rainwater recharge pits that help in groundwater recharge.
The average yield is 20lts/head/day Or 7300lts/head/year.
This system of recycling greywater is integrated within the landscape
CRITICAL APPRAISAL
LANDSCAPING
There is a grey water recycling pit that treats grey water, which is linked to the rootzone of the plants planted around the pit and can be used to flush toilets or water the plants after treatment.
RAIN WATER HARVESTING SYSTEM Collecting Rainwater Where It Falls • Filtration • Storage • Usage for Potable and Non-Potable Purposes • Recharging the Ground Water Table NATURAL WATER FILTER DEWAT SYSTEM (DEWAT) refers to a decentralized, communitylevel wastewater treatment Thetechnology.passive design uses physical and biological treatment mechanisms such as afloatation,naerobic sedimentation,aerobicandtreatmentto treat both domestic and industrial wastewater sources. CRITICAL APPRAISAL
Construction techniques of bio pool
CRITICAL APPRAISAL
What are Bio pools? Bio pools are natural swimming pools. Rather than relying on chemicals to keep them clean, they either use ecological systems (plants) to foster the development of living systems and organisms or manipulate biological stress points to create naturally pure water, like mountain lakes The classic bio pool works by having two zones: a central swimming area and a shallower surrounding area, with plants specially chosen to purify the water. Plants purify water by consuming excess nutrients and de acidifying it by removing carbon dioxide.
BIO POOL
The thundering arrestor is yet another installation that helps prevent lightning damage to the apparatus because of high voltages.
CRITICAL APPRAISAL
A sailor depends on stars to find his way, and this interest of the client helped develop a customized observatory on the terrace which is the most attractive element in the design.
