Colombo city is the business capital in Sri Lanka. The growth of businesses in the city is increasing day by day. As a result of this situation, many urban dwellers those living outside the capital are attracted to the city.

Most of the suburban population who travel to Colombo daily cannot afford to build their own houses within city limits as the cost of land and cost of construction are not within their means. Purchasing an apartment on payment in instalments is an ideal alternative especially to private sector executives who travel to Colombo daily with their whole family as most such children attend prestigious schools in Colombo. The Sky Residencies high-rise building project was planned to cater to this sector of population with availability of state of the art apartments priced reasonably leading to improvement of quality of life.

Sky Residencies is is planned for a height of 165m and consist of 46 stories including 5 parking floors, 40 apartment floors and a recreational floor. This is designed to facilitate 160 apartments with the choice of 2 bedroom and 3 bedroom apartment. Sky Residencies is designed according to the green concept to achieve sustainable development. It will become one of the most sustainable buildings in Sri Lanka and will be unique in its architecture and structural features. Facilitation of obtaining a soft loan from a reputed bank to the purchaser is planned to attract buyers.
