Late Architect Milroy Perera’s legacy is kept alive by his team at Milroy Perera Associates together with Maga construction. Architect Arosha Perera is currently leading the team as project architect.
The late architect’s design proposal will be executed captivatingly in Clearpoint residencies which by far is becoming the future of high rise buildings, with its minimal carbon footprint and reduced maintenance cost – a product of creative architectural design and cutting-edge technology bringing about sustainability, conservation and environmentally responsible living to the forefront. The designer’s aim is to offer sophisticated urban living in a serene country side setting. Milroy Perera was a pioneering Architect alongside Geoffrey Bawa for the design of the Heritance Kandalama. The almost one kilo meter horizontal stretch of greenery at Kandalama has been translated to a vertical stretch with planted terraces circling the entire structure and an inbuilt self-sustaining watering system at Clearpoint residencies. It steps aside from the typical apartment complexes with compacted units while redefining the idea of congested urban living.
Even though the location remains within a few minutes of a drive from the central business district of Colombo, the complex sits peacefully away from the hustle of the busy roads overlooking the Diyawanna Lake. The building consists of 171 spaciously designed 2, 3 and 4 bedroom apartments, a limited number of penthouses and presidential suites spread over 46 floors. A roof top swimming pool, gymnasium, squash and tennis courts are among the many amenities provided in the complex. Upon completion, Clearpoint will be the tallest residential vertical garden in the world, with planted terraces circling the entire structure and an inbuilt self-sustaining watering system. Individual pools will be provided upon early requests of clients while a combined apartment will have the luxury of a shared private pool which is an exclusivity of Clearpoint. In place of ordinary balconies, all apartments will be equipped with large terraces with self-sustaining gardens with an abundance of local species. There is also provision for the occupants to grow their own plants. Maintenance purposes calls out for modularized strategies where the concrete floor would be free from loose soil while the trees will be held by plastic containers. These terraces will prevent the apartments from direct exposure to sunlight. Hence while providing shade; it will also lend itself as an extra entertainment space. These terraces that offer a formation of a green cover through the planting of trees will provide a natural cooling system for the entire building, resulting not only in a fresher and more relaxing atmosphere, but less energy spent on air conditioning. This blanket of planted terraces also endows the building with an innate sound proofing system, blocking out the sounds of the hustle and the bustle of the city around it. Since all apartments receive less heat due to the windows not being exposed to direct sunlight, it has been possible to reduce the size of air conditioners, thus requiring less energy to be used. In addition, all apartments are cross ventilated for the purpose of cooling the inside naturally. All living areas including bedrooms are equipped with multi-split type inverter air conditioners and ceiling fans. These air conditioners are state-of-the-art units fitted with ‘inverter technology’ that consume 40% less energy than average air conditioners. All toilets and bathrooms are mechanically ventilated. The kitchens will have access to natural ventilation but the cooking areas will be mechanically ventilated as well. Electric geysers will be replaced with a centralized gas for heating water. In a significant step towards sustainable development and energy conservation, Clearpoint Residences uses solar panels to generate electricity for common areas and mechanisms such as lobby and corridor lighting, elevators and the recycling system. Additional electricity will be sold to Ceylon Electricity Board using a net metering system. An automated drip irrigation system has been incorporated throughout the building so that terrace gardens are maintenance free. The drip irrigation system will save water when compared with a sprinkler system. Additionally the water used for irrigation is recycled from the grey water output of the residence, which is also used in the sanitation systems of apartments, thus reducing water usage by 45%. One of the main uses of water in apartments is for flushing. In an effort to reduce the water usage, recycled water is used for flushing. Water is collected from apartment showers, bathrooms and sinks. Running it through a recycling system which will purify the water to be less than 10 BOD (Bio Oxygen Demand) the Recycled water is mixed with rainwater and sent through to the bathroom water closets
and to the drip irrigation system, which means flushing and the drip Irrigation does not require water from the mains. Solid waste Generated from the apartment is separated into glass, paper, plastic and metal (with the aid of the occupants) in the garbage room which is situated on each floor and negatively ventilated so outdoors do not escape into the lift lobby. The waste will be then collected and sold to the relevant authorities.
The income earned from this process will be used to maintain the building, further reducing the cost of maintenance. The foundation of the building is built with reinforced concrete piles. The superstructure is a shatterproof concrete tubular structure which encompasses flat slabs, designed for seismic resistance.
Clear point residential complex is planned to be completed and be ready for occupancy by mid-2017. While encouraging sustainable ways of living in the city, the complex will undoubtedly make a turning point in urban architecture in Sri Lanka by setting the benchmark for future high rise developments in the country.
