Abstract: Estimated cost plays an important role to predict the cost of projects need to be provided by the owner. Estimator are often faced with the question of how much is the cost to build homes. To answer that question we need a model that can be used practically by the estimator or even owner in predicting the costs required to finance the construction of residential houses.
The method will be used in this research is to collect data from the developer who lives in Jakarta, the data calculation of estimated costs of quantity surveying consultancy firm, the data interviews and questionnaires. The data collected was processed using Microsoft Excel to get the model estimation.
Development cost estimation model that can be used by the estimator to calculate the estimated price for residential buildings is Y = -622.48 + 16,19X2 + 6,76X3 where Y = cost of construction of houses, X2 = Total land area, X3 = Building Area, after applying the model in residential buildings, the accuracy of the model obtained is in the range of + 5.40% s / d -16.08% of the development cost for the maximum / minimum land area is 140/36 m2 and maximum / minimum for building area is 150/36 m2
