Residence of a Quantity Surveyor at Malabe

The Architectural design was done by Architect, Krishantha and the structural design was done by Chartered Structural Engineer, Isuru S. Amarasena. House is situated around 1 or 2 kilometers away from the Malabe town. The house has four large bedrooms, living, dinning, Kitchen and a large two car Parking area. Lobbies, Ponds, Store rooms and TV lobbies are also included and a garden is also available with a considerable area.

This house is designed in a land with a huge slope where the contour lines are going very closer to each other. The height variation through out the land premise is about 3 floor heights. The soil condition is somewhat good in one edge and in the other edge the soil strength is somewhat weak. The house is two story and a large roof terrace area is included for a ceremonial purpose.

Two major Reinforced Concrete retaining walls were designed due to the existing large level differences. Every floor was deigned in two levels. Some beams were need to be designed as upstanding beams in-order to maintain the architectural features. Square type Pad foundations were used in several places and in the boundary wall line, rectangular type eccentric footings were used. All the columns were tied very well with tie beams as the availability of big slope differences. 9"x9" columns were used with 4T16 bars or 4T12 bars. Access to the water tank area also provided with the RC staircase. This is a good example for a beautiful house design for a rectangular type stripped lands with slopes.
