Over usage of natural resources for construction of buildings has caused many environmental problems. Hence mainstream requirements of building projects such as cost effectiveness and rapid construction should be achieved while ensuring that the impact on the environment is also minimum. In this context, it is beneficial to use recyclable or renewable materials as building elements. This paper describes a successful adoption of the combination of such systems in a rapid building construction project in Sri Lanka. The building envelope consists of two and three storey steel portal frames, walling system based on compressed straw panels, upper floor with precast concrete slab panels supported on a steel framework, and ceiling made from compressed straw panels. The successful application of these systems indicates the possibility to adopt them in the future for rapid, cost effective and sustainable building construction.

Concrete is the extensively used material in the construction industry and there are two main types of concrete. Those are the insitu concrete and precast concrete. In this paper researcher analysis, the factors affecting the cost-effectiveness of using precast concrete wall panels over the block wall construction in Sri Lanka. Here the researcher mainly focuses on the main cost-effectiveness factors of construction of the wall in Sri Lankan construction industry. The main aim of this exploration is to deliver an impression of the growth and submission of Preformed concrete wall panel system in Sri Lanka. Other aims are to evaluate the advantages, disadvantages, and performance of precast concrete wall panels. And identify the limitations and cost effectiveness of the precast concrete wall panels in Sri Lankan Construction industry. In here researcher is going to used semi structured questioners as the main data collection methodology. A researcher is going to be analyzing collected data by using the software. Also, the researcher is planned to compare the precast concrete wall and block wall by calculations. Finally, the researcher is premeditated to conclude by highlighting the comparison of the precast concrete wall panel over the block wall by using charts and mathematical calculations.

"Different conditions made a difference in the housing types adopted in the otherness of a predominantly Western Modernism in the first half of the 20th century. In the second half, Western Europe saw the development of the so-called participative planning, while mass housing in totalitarian regimes was built in Eastern Europe. Economic efficiency, as a benefit-costs comparison, was differently seen. However, in earthquake prone Romania, pre-cast concrete housing was tested 30 years ago full-scale in the 1977 earthquake and proved well-resistant. In this paper two different housing constructions out of pre-cast
reinforced concrete elements are presented, one from the East and one from the West of Europe, analysing the rationale behind and the success of the model adopted. The first is a
multi-family urban housing construction type built in Romania from the 1960s through the 1990s with a load-bearing system constructed from large pre-cast reinforced concrete panels.
Buildings of this type are typically high-rises (10-11 stories), although there are also mediumrise buildings. A low-rise housing complex in the periphery of Wiesbaden is an example of
the use of pre-cast reinforced concrete spatial cells in Germany. Architectural quality was achieved through variety and optimisation obtained through applying the integral planning
method: specialist engineers involved in the first stages of the architectural project."
